Intel Alder Lake source code has reportedly been leaked
Intel Alder Lake source code is now online
Tom’s Hardware reports that Intel could be in trouble after a serious data leak.
It is reported that 12th Gen Core series source code has now been posted online after it was leaked by a 4chan group. The source code is 2.8GB in size after compression, and it appears to contain important information such as BIOS data. The data was already published on Github, however given the size of this leak it may take time to assess what exactly was shared by the perpetrators.
The majority of the data appears to cover BIOS or chipset information for Alder Lake-S CPUs (desktop). Should this leak be proven real, it may uncover some secrets that Intel engineers would probably prefer to keep to themselves. Thus far, there are no reports on any security sensitive data being leaked, for instance Trusted Platform Module source code, which would be a much bigger problem for Intel.
The source code to the Intel Alder Lake has been leaked online.
* Alder Lake CPU was released November 4, 2021
* Source code is 2.8GB (compressed)
* Leak (allegedly) from 4chan
* We have not reviewed the entirety of the code base, it is massive— vx-underground (@vxunderground) October 8, 2022
While the data clearly originated at Intel, the source of the leak may not be the CPU maker itself. It is reported that some data are referring to “Lenovo Feature Tag Test”, which could suggest that OEM partner could be the true source of this leak.
In 2021 and 2022 we have seen some leaks of confidential information that was stolen by hackers. This includes data on AMD new and old future processors or NVIDIA leak that confirmed the codenames of future architecture and configurations of all Ada Lovelace GPUs.
Update: Mark Ermolov, Intel platform security researcher, might have already found some interesting data in regard to SGX (Intel® Software Guard Extensions):

AMD Ryzen CPUs Sold More Than Intel’s Alder Lake CPUs Last Month, Continue To Retain Strong DIY Market Share Hold In Germany
The latest sales and revenue share of AMD’s Ryzen & Intel Core CPUs from Germany’s largest tech retailer, Mindfactory, have been published by Ingebor on Reddit.
Intel Alder Lake CPUs Boost Market Share Globally But AMD Ryzen CPUs Continue To Dominate The DIY Segment In Germany
Over the last couple of weeks, we have reported how the PC market is on a general decline due to rising inflation. Both AMD and Intel are expected to lose desktop revenue in the coming quarter but it looks like Germany’s DIY segment remains a stronghold for AMD’s Ryzen CPUs which continue to outsell Intel’s latest and greatest Alder Lake CPUs.’
Intel Core & AMD Ryzen CPU Sales/Revenue Figures By Mindfactory (Credits: u/Ingebor):
Looking at the sale figures, Mindfactory reports that in June, 63% of the CPUs sold were from AMD and 37% were from Intel. AMD Ryzen CPUs amounted to over 7,500 units while Intel CPU sales hit almost 5,000 units. Of all the AMD CPUs, sold, the most popular CPUs were the Ryzen 5 5600X, the Ryzen 7 5800X, and the Ryzen 9 5950X. In fact, the Ryzen 9 5900X sold more than the mainstream Ryzen 5 5600G and the Ryzen 5 5500. This is mainly due to the discounted deals that the Zen 3 line up received given it’s almost two years old now.
Intel, on the other hand, saw almost the entirety of its sales coming from the 12th Gen Alder Lake lineup. Intel’s most popular CPUs were the Core i7-12700K, the Core i5-12400F, and the Core i5-12600K The revenue split was also the same with Mindfactory’s 61% CPU revenue coming from AMD or over 2.5 Million Euros while Intel CPUs amounted to 39% or slightly above 1 Million Euros worth of sales. You can easily note the downward trend in the sales and revenue figures which is a recall to the declining PC market mentioned above.
Intel Core & AMD Ryzen CPU Per-Chip Figures By Mindfactory (Credits: u/Ingebor):
The highest revenue came from the top three chips, the Ryzen 5 5600X (435,000 Euros), Ryzen 7 5800X (416,000 Euros), and Ryzen 9 5900X (391,000 Euros). Both Intel and AMD CPU prices are on the decline and Intel has recently initiated a retailer-specific price cut which would drop prices by up to 5% on certain 12th Gen Alder Lake CPUs. This price cut is planned for the current month so that won’t be reflected here since these figures are from the previous month.
As for the family split, both Intel and AMD have their latest Alder Lake (12th Gen) and Vermeer (Ryzen 5000) CPUs amounting to 75% of the sales and 83% of the revenue. The AMD Ryzen Threadripper and Intel Core-X HEDT lineup has entirely disappeared from the chips which are due to the fact that DIY enthusiasts haven’t gotten any new product family in over two years. AMD has announced that Threadripper 5000WX CPUs will be coming to the DIY segment but these will be full-fledged PRO parts which will require users to spend a lot more than they used to for the HEDT family.
Based on the report, it looks like Germany will continue to be AMD’s stronghold unless Intel comes up with something really really good. We will see if Raptor Lake is able to take away further market share from AMD in the mainstream segment later this year considering that the red team is going to focus its AM4 on the mainstream and AM5 on the high-end segment.

Dell’s new XPS 13 adds Alder Lake CPUs, but this is more than just a spec bump
Today Dell is launching the 2022 revision of its XPS 13 to include Intel’s latest 12th-gen Alder Lake CPUs that add more cores and a hybrid architecture, while saying the new version is its thinnest and lightest 13-inch XPS ever. The new laptop is 13.9mm thick (0.55-inches) and weighs as little as 2.59 lbs, compared to its predecessor’s 14.80 mm (0.58-inches) and 2.64 lb starting weight for a non-touchscreen model. The new XPS 13 is available starting today in the US and Canada, starting at $999 with Windows 11 or $949 for an Ubuntu 20.04-equipped Developer Edition.
The flagship XPS 13 has gone from previewing the future of laptops when Dell introduced the InfinityEdge design with thin bezels in 2015, to kind of stale a few years later, and now, good enough to earn our review calling the last iteration “everything a Windows laptop should be” on its way to placements in multiple “Best PC laptops” lists.
To avoid accusations the line is becoming stale again, Dell is splitting wilder options out with the XPS 13 Plus that kicked off the year featuring a touch bar, flush keyboard, and slightly more powerful P-Series CPU options, as well as a new 2022 XPS 13 2-in-1 announced today that replaces the old thin and foldable design with a tablet + folio keyboard case.

On the outside, the new 9315 model has a similar look to the 11th-gen CPU-powered 9310 that debuted in 2020 before adding an OLED display option last year, but the differences should show up as soon as you open it.
Dell says it “removed superfluous steps, reduced finishes and materials” on the new laptop that pulls back on contrasting interior to highlight the “curated and premium” CNC machined aluminum that’s now the star of the show both inside and out. It’s a look that’s familiar, but quite clean in either the sky (grey) or umber (brown) tinted aluminum finish, and hopefully, it maintains the sturdy design plus solid keyboard and trackpad we lauded in 2020. Other touches like the fingerprint sensor / power button and Thunderbolt 4 ports on either side remain unchanged, but there’s no headphone jack on the laptop this year.
More notable changes are inside, and address some of the weaknesses we called out on the 9310, with a bad webcam, speakers that lacked bass, and a keyboard that could get hot to the touch under load. The internal layout has been redesigned to include Dell’s smallest motherboard ever, which measures 1.8x smaller than the previous model, making room for larger speakers and other tech. The spec sheet mentions using that space for a larger battery, however, it lists the new model’s unit at 51 watt-hours, compared to the 9310’s 52. It also has a single fan design now instead of dual.
We’ll need to review the new model to see what its new chipset and design make of those changes, which could be an area for the new Alder Lake CPUs inside to shine. As we’ve explained before, this generation of Intel chips is better positioned to do battle with the competition from AMD, Apple, and everyone else by adopting a setup similar to many ARM-based CPUs, with more cores that are split up between ones built for performance or power efficiency.
At launch, Dell is listing two 10-core CPU choices of either Intel’s i5-1230U or i7-1250U with Iris Xe graphics, RAM choices of 8GB, 16GB, or 32GB, and SSDs in 256GB, 512GB, or 1TB sizes. According to Dell, the most power-efficient i5 model could stream Netflix continuously for up to 12 hours, or 11 hours on the most efficient i7 setup, and up to 6 hours on a model equipped with the i7 chip, 16GB RAM, 1TB SSD, and 4K display.
As far as displays, there’s no new OLED-equipped version available now, with choices including a 4K UHD+ (3840×2400) touch display, or FHD+ (1920 x 1200) in either touch or non-touch configurations. This year it includes support for WiFi 6E, however built-in 5G is reserved for the upcoming 2-in-1 version. The aluminum in the frame is low-carbon to reduce its carbon footprint, while this year’s model ships in new packaging made of “100 percent recycled or renewable content.”
The webcam is updated too, separating the infrared and RGB sensors in ways the company says will make you look better in low light, and while Dell finally put the camera in the right spot a few years ago, it’s still limited to 720p. Whether or not that’s true, this model is also adding Dell’s ExpressSign-In tech that uses a proximity sensor in combination with the Windows Hello facial recognition-capable webcam to detect when you’re in front of the laptop and automatically log you in, as well as lock it when you walk away or dim the screen to save battery life while you’re looking at something else.
AMD Ryzen 7 5800X3D CPU Beats Intel Core i9-12900K In Gaming Benchmarks Despite Alder Lake Using High-End DDR5 Memory
AMD’s Ryzen 7 5800X3D has been tested against the Intel Core i9-12900K once more and we will see if DDR5 is enough to keep Alder Lake in lead.
AMD Ryzen 7 5800X3D Retains Gaming Lead In Latest Benchmarks Against Intel Core i9-12900K Despite Alder Lake Running DDR5-6000 Memory
The latest gaming benchmarks for the AMD Ryzen 7 5800X3D are once again published by tech outlet, XanxoGaming. Today is also the day when other media outlets will be posting their own 5800X3D reviews.
The previous benchmarks did feature the AMD Ryzen 7 5800X3D running against an Intel Core i9-12900K CPU but only with DDR4 memory up to 3600 Mbps. The latest benchmarks show us what the performance looks like when the new 3D V-Cache CPU is tested against Alder Lake with DDR5 memory. For this purpose, a set of DDR5-6000 CL40 memory was utilized, and that gives another $ advantage to the red team considering the high prices attached with going the DDR5 route on the Z690 platform. Meanwhile, users can simply run their existing DDR4 kits on the AM4 platform and the CPU upgrade alone will allow for much higher performance.
As for the benchmarks, besides Assassin’s Creed Origins, the AMD Ryzen 7 5800X3D outperformed or managed to stay on par with the Intel Core i9-12900K (Plus DDR5-6000 memory). This is again an impressive showcase of 3D V-Cache offering a bigger performance bump over Intel’s fastest Alder lake CPU for gaming. Another section where 3D V-Cache really helps is the 1% lows which are much higher than what Intel’s Core i9-12900K produces in the same games.

The Ryzen 7 5800X3D is turning out to be a great gaming CPU as far as its price is compared to the Intel flagship, the Core i9-12900K. AMD can have a very disruptive offering as it says its last hurrah to the AM4 platform. It will be available for $449 US when it hits retail on the 20th of April.
AMD Ryzen 7 5800X3D reaches gaming performance parity with Intel Alder Lake in another early review
AMD Ryzen 7 5800X3D tested
Another day, another review of AMD latest gaming Zen3 CPU has just been posted by TechPowerUP.
AMD Ryzen 7 5800X3D, Source: TechPowerUP
The official review embargo for 5800X3D lifts in 2 days (April 14th), but the CPU will not be available for sale until April 20th. This has clearly not stopped tech reviewers from obtaining a sample sooner. After the first review from XanxoGaming, we now have TechPowerUP review, which carries a lot more data. We have confirmed that this TPU is not required to wait till April 14th, because they never signed the NDA. Therefore, one should not expect this review to ‘disappear’.
What this review obviously does not have are official launch charts. What we can tell is that there are some more detailed gaming charts there, but that shouldn’t really matter anymore, because we now have two sites with independent results. That should give us a good idea of what to expect.
It is worth noting that TPU ran 5800X3D with 2x 16GB DDR4-3600 (16-20-20-34 1T) memory and Alder Lake CPUs with 2x 16GB DDR5-6000 (36-36-36-76 2T / Gear 2. The X570 Gaming motherboard was updated to the latest AGESA 1.2.0.6c supporting 5800X3D. All games were tested with GeForce RTX 3080 FTW3 Ultra from EVGA.
With permission, we are only sharing relative gaming performance charts with three resolutions: 720p, 1080p, 1440p and 2160p. AMD has put a lot of emphasis on gaming performance of this new 8-core Zen3 processor with 3D V-Cache, claiming 15% higher performance on average than Ryzen 9 5900X. Unfortunately, this claim is not reflected in relative performance charts prepared by TPU. The media tested the following games: Battlefield V, Borderlands 3, Cyberpunk 2077, Doom Eternal, Far Cry 5, Metro Exodus, RDR2 and Shadow of the Tomb Raider.

What is confirmed though is the fact that 5800X3D trades places with Intel’s Core i9-12900K processor in gaming tests. With 140 USD lower price tag and well-established AM4 platform, that shouldn’t go unnoticed by potential buyers.
The CPU lacks overclocking capability and has lower clocks though, this means that in application test suit it is actually 3% slower than Ryzen 7 5800X (without the 3D V-Cache). In games, however, it is a worthy counterpart to Intel 12th Gen series, the reviewer even says that the 5800X3D reached gaming parity with Alder Lake.
Averaged over our 10 games at the CPU-bottlenecked 720p resolution, the Ryzen 7 5800X3D can gain an impressive 10% in performance over its 5800X counterpart. […] Individual games will show vastly different results though, the highlights here are Borderlands 3 and Far Cry 5. Borderlands 3, which has been extremely CPU limited in all our testing gains an enormous 43% (!!) in FPS. Far Cry 5 is the most memory-sensitive title in our test suite, +35%, wow!

Spectre V2 vulnerability strikes again in Intel Alder Lake & Arm CPUs, AMD chips unharmed
VUSec security research group and Intel have revealed another Spectre-class speculative execution vulnerability called branch history injection, or BHI. The new exploit impacts all Intel processors released in the last several years and specific Arm core processors. Intel processors affected include the most recent 12th Gen Core Alder Lake CPUs. Surprisingly, AMD chips have shown no effect from the vulnerability at this time.
Spectre V2 hits Intel and ARM CPUs once again, affecting newer Intel and Arm cores
BHI is a proof-of-concept attack affecting vulnerable CPUs open to Spectre V2 exploits. The interesting part of this particular attack is that several mitigations were currently in place on the affected CPUs. BHI avoids the Intel Enhanced Indirect Branch Restricted Speculation (EIBRS) and the Arm ID_PFR0_EL1 CSV2 assignment. VUSec reports that BHI enables cross-privilege Spectre-v2 exploits, allowing kernel-to-kernel (intra-mode BTI) exploits and permitting attackers to place predictor entries into the global branch prediction history make kernel leak data. The result of the attack leaks arbitrary kernel memory on specific CPUs and could reveal hidden data such as passwords.
Intel reports that the company’s processors starting with Haswell (introduced in 2013) and spread to the recent Ice Lake-SP and Alder Lake CPUs. Intel will release a security patch to mitigate the exploit.
Arm cores, such as the company’s Cortex A15, A57, A72, Neoverse V1, N1, and N2, are reported to be affected. The company will also introduce five mitigations for their affected core series. It is currently unknown if custom series, such as the cores from Qualcomm using Arm’s technology, are affected by the new exploit.
Linux systems have received mitigations for Spectre-BHB / BHI on Intel & Arm-based systems. There were added security measures for AMD systems that could potentially be affected.
Client and server machines should not be affected as long as those machines have the installed patches from the two companies. The impact the mitigations will have on performance on affected devices is unknown. Security researchers advise disabling unprivileged eBPF support to increase precaution from the attack.
The attack, as demonstrated by researchers, was previously mitigated by default in most Linux distributions. The Linux community has implemented Intel’s recommendations starting in Linux kernel version 5.16 and is in the process of backporting the mitigation to earlier versions of the Linux kernel. Intel released technical papers describing further mitigation options for those using non-default configurations and why the LFENCE; JMP mitigation is not sufficient in all cases.

Intel Forcing Motherboard Makers To Disable AVX-512 Support Across All Alder Lake CPUs Through Upcoming BIOS
During our testing of the Intel Alder Lake Desktop CPUs, we discovered that AVX-512 support was left untouched and could be enabled with ease though this instruction set is all set to be disabled through an upcoming BIOS.
Intel Alder Lake Desktop CPUs To Lose Their AVX-512 Instructions With The Next Major BIOS From Motherboard Makers
While Intel’s Alder Lake CPUs are not officially stated to support AVX-512 instructions, they can be enabled by disabling the efficiency ‘Gracemont’ cores and leaving the performance ‘Golden Cove’ cores running. This delivers slightly better performance and higher efficiency than the standard AVX2 instructions. While the E-cores have their own advantages in a number of workloads, it looks like the AVX-512 instructions net higher efficiency too.
But that’s all about to be changed as Igor’s Lab reports that Intel has been directing motherboard makers to remove support for AVX-512 on Alder Lake CPUs through an upcoming BIOS update. It’s no surprise that this move comes just a few days before Intel plans to launch its non-K Alder Lake lineup which will feature a majority of P-core-only models (Core i5 and Core i3 to be non-hybrid).

These chips have the potential to be a hot item for entry-level servers and workstations where their AVX-512 goodness can be put to use. Intel doesn’t want that to happen and as such, they are trying their best to remove support of the instruction set from the equation. However, there’s more, Igors Lab explains that the standard AVX2 instructions have a very strict thermal throttling feature across all hybrid chips which is recognized within HWiNFO as ‘IA: Max Turbo Limit – Yes’.
Intel Alder Lake AVX512 & AVX2 Support / Limits in HWiNFO (Image Credits: Igor’s Lab):
The thermal lock results in limited clock speeds and a reason stated is to avoid electron migration degradation inside the new chips. Now there are a few systems that can hit the 5.2 GHz max clocks of the chip due to these throttles as many PCs won’t have adequate cooling to hit those high clocks.
Fortunately, there are already workarounds for both of these AVX hurdles, the throttling of AVX2 and the removal of AVX-512. For example, Asus has implemented a patch in their BIOS versions for “Maximus” series motherboards that disables AVX2 throttling. The only important thing here is that the clock must already be set in the BIOS at boot time. A subsequent change via in-OS software will otherwise get caught in Intel’s catch net again.

Now you can hold on to your existing BIOS and retain AVX-512 instructions but the latest stock of motherboards are expected to carry these BIOS out of stock. Also, you’d definitely need a better BIOS from the one available at launch to have good stability and DDR5 compatibility of your Alder Lake CPUs but upgrading would mean saying goodbye to the instruction set. So it’s a really weird move by Intel and if they are being so furious about this one feature on consumer CPUs, then they shouldn’t have had it in the first place.
Intel Demos Samsung PM1743 PCIe Gen 5.0 SSD on Alder Lake Platform, Almost Hits 14 GB/s Bandwidth
Intel has demoed Samsung’s recently unveiled PM1743 Gen 5.0 SSD on its Alder Lake Desktop CPU platform, showcasing the improvements in bandwidth against a Gen 4.0 SSD.
Intel Puts Alder Lake’s Gen 5.0 Capabilities To The Test With Samsung’s PM1743 SSD, Achieves Almost 14 GB/s Throughput
The demo was showcased by Intel’s Chief Performance Strategist, Ryan Shrout, who had the whole thing planned out for a press unveil at CES 2022 but since all major companies have backed out & canceled their on-site events, switching over to virtual-only conferences/keynotes, Ryan decided it was time to show the PCIe Gen 5.0 capabilities over on his Twitter feed.
Perks of the job! Was going to save this demo for #CES2022 but with that off the table, why not just share it with everyone right now?! Here’s a 12th Gen @intel Core i9-12900K system paired with a new @Samsung PM1743 PCIe 5.0 SSD getting over 13GB/s!! pic.twitter.com/oyL08KzDtV
— Ryan Shrout (@ryanshrout) December 30, 2021
The demo is comprised of an Intel Alder Lake Core i9-12900K CPU that was running on an ASUS ROG Maximus Z690 APEX motherboard. The APEX comes with two PCIe Gen 5.0 slots (x16 & x8), electrical. While the GPU, an EVGA RTX 3080 FTW3, was installed in the first slot, the second slot featured an adapter board that let Ryan equip the Samsung PM1743 SSD. The adapter is used to convert and adapt the enterprise tier or any 2.5″ drive to the PCIe slot using an x4 interface.
With the SSD installed, what’s left to see is the performance and like most high-end PCIe Gen 4 SSDs, the one Ryan used to compare (WD SN850) ended up with around 7000 MB/s throughputs. It was a bit lower than 7000 since the drive had an OS loaded onto it but the Samsung PM1743 Gen 5 SSD ended up almost twice as fast with blisteringly fast speeds that could read 14,000 MB/s or 14 GB/s within the IOMeter test.
Ryan also mentions that he did test dual Samsung PM1743 SSDs too, probably in RAID0 mode, and hinted that they were ‘fast’. You can see the two PCIe Gen 5.0 SSDs running together and offering up to 28.3 GB/s of throughput which is literally insane.
A few asked why we didn’t show both of the PCIe 5.0 drives running at the same time. Fine @IanCutress here you go. Addressing them independently in IOmeter for a combined bandwidth over 28 GB/s!! https://t.co/107wlJ4wit pic.twitter.com/c8fecGkxli
— Ryan Shrout (@ryanshrout) December 30, 2021
PCIe 5.0 offers a bandwidth of 32 Giga transfers per second (GT/s), doubling that of PCIe 4.0. Leveraging a proprietary controller designed to support the latest PCIe standard, the PM1743 will deliver outstanding read and write speeds to accommodate the rapidly increasing performance requirements of data centers.
Samsung’s PM1743 will feature a sequential read speed of up to 13,000 megabytes per second (MB/s) and a random read speed of 2,500K input/output operations per second (IOPS), offering 1.9x and 1.7x faster speeds over the previous PCIe 4.0-based products. Moreover, write speeds have been elevated significantly, with a sequential write speed of 6,600 MB/s and a random write speed of 250K IOPS, also delivering 1.7x and 1.9x faster speeds, respectively. These remarkable data transfer rates will allow enterprise server manufacturers deploying the PM1743 to enjoy a much higher level of performance.
via Samsung
Samsung is the first to offer PCIe Gen 5.0 compliant SSDs of the enterprise but we can expect other manufacturers to hop onboard the consumer/enterprise bandwagon later next year as Gen 5 gets a wider adoption by the next-generation of AMD and Intel CPU platforms.
