CPU Benchmark Performance: Power, Office, and Science
Our previous set of ‘office’ benchmarks has often been a mix of science and synthetics, so this time we wanted to keep our office section purely on real-world performance.
For the remainder of the testing in this review of the Ryzen 7 5800X3D, we are using DDR4 memory at the following settings:
- DDR4-3200
Power
Looking at the power draw between the Ryzen 7 5800X3D and the other chips tested, it is more power-efficient than the original Ryzen 7 5800X. This could be down to a load VID core voltage as the 5800X3D is actually clocked lower by 100 MHz at turbo clock speeds.
Office
In our office benchmark, the newer Ryzen 7 5800X3D performs similarly to the previous Ryzen 7 5800X processor.
Science
Our science-based benchmarks, for the most part, show that the Ryzen 7 5800X is slightly better computational-wise than the Ryzen 7 5800X3D. This is primarily due to the 5800X being clocked 100 MHz higher than the newer 5800X3D.
Where the extra L3 cache can benefit performance, it does, including in AI Benchmark, but overall the performance is very similar between both chips.

They probably found it not as important as this one.Kangal - Friday, July 1, 2022 - link
There's no Andrei... so maybe you're right.iphonebestgamephone - Friday, July 1, 2022 - link
Andrei be busy with the nuvia cores.Silver5urfer - Thursday, June 30, 2022 - link
Forget this chip because at this point anyone is better off with a 5900X as it's far superior in MT plus higher cores. This thing is locked for tuning, and the X3D is causing the clock speed deficit on top. The only advantage is low voltage for PBO as it runs at 1.3v only vs the usual Zen 3 at 1.4v.The major issue is AMD BIOS and Firmware. It's not upto the mark the 1.2.0.7 is finally out it fixes a lot of things BUT the core problems of USB are not fixed. Anyone who has Ryzen 2000 should get a 5900X once Ryzen 7000 launches, not only you can get more cores at cheap plus also a beast at MT which can be used at any task. Not some gaming only junk. This thing struggles on RPCS3 emulation too. You need ST performance and high clocks for such and major workloads the L3 cache is great but the limitations are not worth spending over $450 for this, you can get a 10850K for $320 if you looked for deals, that's a 10C20T CPU which will destroy this processor in all workloads and if you add OC it will be as fast as a 12th gen, check Tomshardware CPU ranking list for gaming here and see for yourself how 10th gen fares better you don't have to deal with BS BIOS issues, USB problems etc

For those who want to buy new, wait for AMD Ryzen 7000 or Z790, Z690 has ILM problems you must avoid it. Ryzen is buggy platform. You are left with Intel 10th gen, it's best but the PCIe3.0 is it's downside.

The fact that it can trade blows with the 12900K/S often in gaming makes the 5800X3D impossible to so easily dismiss for current AM4 owners. You could get a cheaper 5900X, but if you don't need the extra cores, you won't notice the difference.It would be better to get it on sale for far less than $450, but the supply might be kept low to make that difficult. AMD gets more $$$ from sending these cache chiplets to Epyc Milan-X customers.
Going forward, I think AMD should offer the 16-core 7950X only with V-Cache, delaying it after the other models, and 7800X with and without V-Cache.

That won’t happen as again 7950X is a mixed cpu not entirely for gamers. So the likeliness is high only the 8 core will get 3DVCache again.nandnandnand - Thursday, June 30, 2022 - link
I don't think they will launch it on only the 8-core 2 generations in a row. 5800X3D is an experiment, soon it's time to make it normal. 7950X is the obvious choice since it uses good chiplets and it's a low-volume halo product.It would also be nice to see a 6-core with a bad yield partial cache chip on top, but that's probably a pipe dream.
Khanan - Friday, July 1, 2022 - link
3DVC mostly scales for gaming so again it makes no sense to give it a production CPU. And lol no 7950X is no low volume product, if sells in the millions. It’s a content creation CPU, also who said 5800X3D is a experiment? Lol so many nonsensical comments hereSilver5urfer - Friday, July 1, 2022 - link
5800X3D is an experimental SKU, the fact that it cannot handle tuning is first, second it's not high saturation since Zen 3 is already at peak which means it's low volume. Third, this is a reject EPYC chiplet which is why AMD segregated it to a single SKU vs whole Stack of X3D refresh on Zen 3. Plus this thing is just AMD looking at how things work IRL when they use their 3D Cache for Consumer processors to understand how the CPU makes market react.It is not going to get any new consumers for AMD, AM4 is a dead end socket. Using this SKU priced at $450 to buy is worse and I certainly would not given the QC of AMD in Firmware.
Anything I disagree = nonsense I guess lol.

It would make more sense if AMD did one more "experimental" release with V/3D-Cache on their 8-core Zen4 processor (r7-7800X3D). But then I think they should offer it throughout the product stack, utilising the "X" moniker, and making their Planar/2D-Cache on their regular options:- r9-8950 vs 8950X
- r9-8900 vs 8900X
- r7-8800 vs 8800X
- r5-8600 vs 8600X
