AMD's Ryzen 7 5800X3D, the new 3D V-cache processor revealed at CES, may only be produced in small numbers when it lands in early 2022 – and the chip may remain thin on the ground until the second half of the year rolls around, going by the latest from the rumor mill.
This comes from DigiTimes (via PC Gamer), which reports that TSMC, which is making the 5800X3D, is only expected to kick off with 'small-volume production' of the processor, according to the usual industry sources in the know. However, the report also makes clear that production could ramp up considerably when TSMC's new packaging plant in Chunan (Taiwan) goes live later in the year (supposedly in the second half of 2022).
So, while everyone is (rightly) cautious about the potential amount of stock when it comes to many new PC components at launch, it appears that the Ryzen 7 5800X3D could be particularly shaky to begin with – perhaps for the first few months of the CPU being on shelves (or not, as the case may be).
At least if this report is correct, anyway; and note we certainly must be cautious on that score, as DigiTimes isn't always the most reliable media outlet.
[...] We know that component shortages are making life difficult for AMD (and everyone else) anyway, certainly for the first half of this year, and as PC Gamer points out, the company has to prioritize enterprise chips (Epyc) to a large extent at the high-end as these are big profit spinners.
On average at 1080p, the 5800X3D is ~9% faster than the 12900K, which costs 30% more, and ~7% faster than the Core i9-12900KS, which costs a whopping 64% more. That means the Ryzen 7 58000X3D is now both the fastest gaming chip in our test suite and a better value for gaming specifically than the Core i9 models.
Overclocking either of Intel's Core i9 models requires a beefy cooler and robust motherboard. However, despite its much tamer overall power requirements, the Ryzen 7 5800X3D is still ~3% faster than the overclocked 12900K in our cumulative measurement.
[...] AMD's marketing claim is that the Ryzen 7 5800X3D is, on average, 15% faster than the Ryzen 9 5900X. The 3D V-Cache doesn't improve performance in all games, so this will vary, but we recorded a 21% increase over the 5900X at 1080p in our test suite, which is incredibly impressive.
The 5800X3D and the 5800X are built from the same basic design, but the X3D model has a 200 MHz lower boost and 400 MHz lower base clock than the 5800X. Despite that limitation, we recorded a massive 28% gain over the 5800X at 1080p, which is impressive. However, overclocking the 5800X3D's [DDR4] memory yielded an average performance increase of only about 1%, which isn't too meaningful.
[...] These results clearly show that the Ryzen 7 5800X3D is a chip designed specifically for gaming, not for leading-edge performance in application workloads. We've highlighted the 5800X3D beating the 12900K in gaming, but we'd be remiss if we didn't mention that the 12900K is 29% faster in single-threaded work and 62% faster in threaded applications. That chasm grows even larger with the Core i9-12900KS.
