GM is the top car seller in America, retaking the title from Toyota
New York
CNN
—
One year after losing the title it held for nearly a century as the top car seller in America, General Motors is back on top.
GM
(GM) reported Wednesday US sales of 2.3 million vehicles. Strong fourth quarter sales, up 41% from a year ago, allowed it to end the year with sales up nearly 3% from the 2.2 million US vehicles it sold in 2021, when it suffered a 13% decline.
Meanwhile Toyota
(TM), which had captured the top sales spot in 2021, had its full-year sales fall nearly 10% to 2.1 million, despite posting a 13% increase in fourth quarter sales.
In each of the last two years, industry-wide auto sales were limited by a shortage of parts, primarily computer chips, needed to build the cars and trucks consumers wanted. Total US new vehicle sales are expected to be down to just less than 14 million vehicles when the final sales results are reported across the industry later this week.
That would be the lowest sales total since the country was just climbing out of the Great Recession more than a decade go. Sales bottomed out at 10.5 million in 2009, the year GM and Chrysler declared bankruptcy and received federal bailouts, and had only climbed back to 12.7 million by 2011, the last year the industry sales fell below 14 million.
Sales had been 17 million in 2019, the year before the pandemic upended both the economy and supply chains.
Most forecasts say the supply chain problems are getting better, and that should allow automakers to increase production in 2023. They point to the better sales that took place in the fourth quarter than earlier in the year as a proof of that, even with higher car prices and rising interest rates making it more expensive for buyers than in the past.
That in turn has led them to forecast a modest increase in sales this year to just north of 14 million vehicles once again.
But many experts caution that their forecast of increased sales depend on the US economy not falling into recession, and instead simply experiencing slower growth. And uncertainty about what will happen to the economy is making the outlook for car sales far more uncertain than in years previous, they say.
“I’ve been forecasting the car market for decades now. This next year is the most challenging,” said Charlie Chesbrough, chief economist for Cox Automotive. “Normally we an idea which way it is headed. But this year it could be up or down.”
There are a number of factors supporting new car sales in the coming year, even if the economy stumbles. One is the fact that car rental companies have not be able to buy the supply of new cars they need in the last two years, as automakers limited the supply of cars available for lower priced fleet sales, selling all or virtually all the cars they had to consumers instead.
“Rental companies have been running at half of the purchases that they’re accustomed to,” said Ivan Drury, director of insights at Edmunds.
And Drury said if automakers start to see weakness in consumer demand, they can bring back incentives, including lower rate financing, that they haven’t had to offer in recent years when there was more demand than supply.
“The incentives recently have been virtually nothing,” he said.
So far demand is still strong, as there is pent-up demand from potential buyers who have delayed purchases because they couldn’t find the vehicle they wanted. But both Drury and Chesbrough say the higher average prices and higher interest rates are already driving buyers out of the market.
A turn in the economy, especially if historically low unemployment rates start to rise, could quickly result in lower new car sales.
AMD Zen 4 Ryzen 9 7950X and Ryzen 5 7600X Review: Retaking The High-End
Back at CES 2022, which was held in Las Vegas earlier at the beginning of the year, AMD announced that its new Zen 4 core would be coming sometime in the second half of 22. During AMD’s ‘together we advance_PCs’ live streamed event at the end of August, AMD unveiled its Ryzen 7000 series of desktop processors, with four SKUs aimed at different product segments. Today AMD has officially launched Ryzen 7000 with the Ryzen 9 7950X sitting as the brand’s representative of performance leadership in an x86 processor for desktops.
On paper, the AMD Ryzen 9 7950X is a 16C/32T behemoth to take overall performance leadership in desktop computing. Their entry point into the market is the Ryzen 5 7600X, which has 6C/12T and harnesses all the benefits of the flagship in a more svelte and affordable chiplet-based package. AMD pins its hopes on bringing that all-important performance crown back to its side with Zen 4 with its new architecture based on TSMC’s 5 nm process; prepare for battle. We’ve detailed what Zen 4 brings to the table regarding the new microarchitecture and tests the new Ryzen 9 7950X and Ryzen 5 7600X through our CPU suite.
New Zen 4 Core on TSMC 5nm, Boost Up to 5.7 GHz!!
The latest Ryzen 7000 series of processors are direct replacements to the Ryzen 5000 series, with a new chipset andell as a newly designed microarchitecture both on the front and back end of the silicon’s design.
As it stands at the time of writing, AMD is launching four processors based on its 5nm Zen 4 core, ranging from a 6C/12T part all the way up to 16C/32T; just like with the previous Ryzen 5000 (Zen 3) and Ryzen 3000 series (Zen 2) launches.
The Ryzen 9 7950X: 16 Cores, 32 Threads, New 170 W TDP: $699
Looking at the specifications of the four AMD Ryzen 7000 processors, the top SKU is the Ryzen 9 7950X, with sixteen Zen 4 cores (two threads per core, 32T) two eight-core core 5nm CCDs. The Ryzen 9 7950X has a base frequency of 4.5 GHz, with a turbo frequency on one core of 5.7 GHz,, which as it stands, is the fastest CPU core in the world for the desktop space today.
AMD has also given the Ryzen 9 7950X a larger 170 W TDP, which when compared to its Ryzen 5000 counterpart, the 5950X, is an increase of 65 W (170W versus 105W) This increase in overall power has allowed AMD to improve on its frequencies, as well as giving its Precision Boost Overdrive overclocking technology more room to breathe; more power typically means more performance.
The Ryzen 9 7900X, Ryzen 7 7700X, and Ryzen 5 7600X
Moving one down the stack is the Ryzen 9 7900X, which is a 12C/24T and 170W TDP part; it has a higher base frequency than the 7950X of 4.7 GHz, but with a slightly lower boost frequency of up to 5.6 GHz. AMD has launched one Ryzen 7 part designed for mid-range desktop computing, through the Ryzen 7 7700X, which is an 8C/16T SKU, with a boost frequency on a single core of up to 5.4 GHz, with a base frequency of 4.5 GHz.
Focusing on the entry-level segment, its Ryzen 5 7600X looks to capitalize on offering 6C/12T with its previous series maximum TDP o 105W, at a reasonable price point. The Ryzen 5 7600X includes a base frequency of 4.7 GHz, with a modest (compared to Ryzen 9) boost frequency on a single core of 5.3 GHz.

Comparing apples to apples, so to speak, from the new Zen 4 generation to the previous Zen 3 generations with like-for-like products, Ryzen 7000 has made some big overall improvements to the chips’ capabilities. Starting at the top tier, the Ryzen 9 7950X has an enormous improvement in base and boost frequencies, which makes Zen 4’s efficiency better than any previous Ryzen generation.
This has been possible in part through superior power efficiency, as the Zen 4 article is largely a Zen 3 refinement, but produced on TSMC’s 5 nm process node (from TSMC 7 nm). This efficiency has allowed AMD to boost clockspeeds without breaking the power bank, with the 105W TDP 7700X seeing a 700MHz improvement for no change in TDP. Coupled with a 13% TDP improvement, and the Ryzen 7000 series chips can deliver some significant single-threaded performance gains. And multi-threaded performance is not left out in the cold, either; by increasing their top TDP to 170W, AMD is able to keep the CPU cores on their 12C and 16C parts at higher sustained turbo clocks, delivering much better performance there as well.
Of course one of the key arguments here is that more power equals more which is true on the part of Ryzen 7000 series. Ryzen 7000’s TJ Max for its Precision Boost Overdrive technology stands at 95°C, which means that the CPU will use all of the available thermal headroom to maximize performance.
Although this can be overridden when manually overclocking, this opens up the maximum TJ Max to 115°C. It’s key to note that users will need to use more premium and aggressive cooling types to squeeze every last drop of performance from Zen 4. The fact that Ryzen 7000 runs hot is accounted for by AMD through their design choices and implementations. As such, they have opted not to bundle their own CPU coolers with the retail packages, instead directing buyers to fairly powerful third-party coolers.
New AM5 Socket: AM4 Coolers will Support AM5 Too
AMD has also transitioned to a new chipset for Ryzen 7000, named AM5. Along with AM5 also comes a new socket, the LGA1718. Now what’s interesting is AMD has specified that most AM4 socketed coolers will support the new LGA1718 socket on AM5; this is great for keeping with compatibility from the previous generation.
This also means that AM4 is now a thing of the past, although it does offer some incredible right now, as well as support with the cheaper DDR4 too. AMD has of course switched to support for DDR5 memory, with JEDEC settings across all four CPUs set at DDR5-5200; an improvement in Intel’s 12th Gen Core series support for DDR5-4800.
AMD has unveiled four new chipsets, two Extreme variants named X670E and B650E, with two regular chipsets, aptly named X670 and B650, original and simple. The top tier X670E series will feature both PCIe 5.0 lanes to the top PEG slot, with support for PCIe 5.0 storage devices which are expected in November 2022. As for its regular X670 chipset, PCIe 5.0 to the PEG slot is optional, not mandatory, like on X670E.
The B650 chipsets are designed to be more affordable and, as such only feature PCIe 4.0 lanes to the PEG slot. They do, however feature at least one PCIe 5.0 x4 storage slot. The B650E is reserved for those lower-end boards that want to include PCIe 5.0 to the graphics card, although users looking to utilize PCIe 5.0 support should opt for,X670E; better boards, better controllers, and better specifications.
New I/O Die: TSMC 6nm For Ryzen 7000
As we’ve seen previously from the Ryzen 5000 series, AMD uses chiplet packaging, with two core complex dies (CCD) on its top SKU, with an I/O die hosting all of the PCIe 5.0, the integrated memory controller (IMC), and new for Ryzen 7000, two CU’s of AMD’s rDNA 2 integrated graphics. Some key advantages of AMD’s new 6 nm TSMC I/O die means more transistors, better efficiency at the manufacturing stage, and ultimately most importantly of all, from an efficiency point of view, lower overall power draw.
