AMD Ryzen 7 5800X3D Retail CPU Gets First Independent Tests
An early retail unit of AMD's upcoming Ryzen 7 5800X3D has made its way to a Peruvian site called XanxoGamging, who put it through its paces in a few benchmarks, of which none so far are game related. The tests run on the upcoming CPU suggests that it's about as fast as a Ryzen 7 5700X in most single and multi-core tests. This should largely be down to the slower clock speeds of the Ryzen 7 5800X3D, which holds it back in these benchmarks compared to the older Ryzen 7 5800X.
However, it seems like some benchmarks can take advantage of the extra cache and the Ryzen 7 5800X3D is outperforming the 5800X in Blender, by a small margin. That said, the Cinebench R23 results are not overly impressive, neither are the CPU-Z or Geekbench 5 numbers. None of this is really unexpected though, especially as AMD has specifically mentioned that the 3D V-Cache doesn't bring additional performance to most software. XanxoGaming has promised more benchmarks and game tests tomorrow, but mentions that it feels strange losing performance in normal software due to the lower clocks, but that they hope the performance can be improved over time by an improved UEFI/AGESA.

The tests were done with 3200MHz CL14 RAM, so that could account for some of it, but not much.
Also 1.2.0.6 C is needed, but the full support version is 1.2.0.7 with the “for now” unofficial chipset driver.
So of course, people test synthetic benches that don't benefit from the cache.Oooooooor you could understand that's totally irrelevant, as the cache doesn't help cinebench performance at all.
At best I would consider it a beta-test for future technologies...
Pretty obviously, extra cache will only help workloads where the same instructions are continually repeated and enough of them will fit in the cache to give that advantage.
Any benefit will be game and engine specific. What code will fit in the extra 64mb l3 that would have come from RAM before?
Will we see games that won't benefit, or be even slower due to slower core clock, and some that will benefit more? And reviewer coul then pick and choose which message he wants to display? :-)
Interesting note in the F36c bios on that mobo.

- benefits gaming,
- no major increase in consumer workloads,
- benefits in enterprise workloads (depending on use case).
Granted, no one will use 5800X3D for enterprise workloads, but that's where Milan-X steps in, which is already used in the industry.
But as usual, wait for actual gaming benchmarks.
That's Samsung B die. Was quite expensive, and can be easily overclocked to maximum Ryzen can even handle in 1:1. How many Ryzen users have quicker RAM? And how much does it even matter in benchmarks that do scale - as oposed to Cinebench, also most games outside fringe cases, min frames or ultra high framerate?
And no, "PBO +200MHz overclocking" never worked as AMD explained in that video. A lot of time and resources was spent to even get Ryzen 3000 processors to achieve marketed boost clocks (even for just a fraction of a second), forget achieving anything higher in a meaningful way.

And true, 3000 series never boosted that high for long. Zen 3 sure did, easily.
It's an overclocking feature for tweakers, it was never advertised by amd as "+200Mhz all the time" or anything
AMD themselves said that the biggest beneficiary of all that extra cache is gaming. I expect things like rendering and compiles to get negligible benefit as those things are generally not cache-limited in any way on the existing 5800X.
i guess it'll be as fast as a 5800X at 5Ghz all core in games.
The performance gain is not in all tasks. But the Milan-X benchmarks have shown that there are substantial gains, it remains to be seen if any of these apply to our use.
