Poll: Ryzen 7950X3D, 7900X3D, 7800X3D

Will you be purchasing the 7800X3D on the 6th?

It's complicated and can change on a per game basis, but overall the best configuration for the 7950X3D is all 16 cores enabled, but SMT on. Two outliers to this are Cyberpunk and Spiderman, both work better with SMT on. Spiderman must have been patched recently because that was not the case previously. Some games will run slightly faster with the second CCD disabled, however aside from benching runs it's probably not worth the effort to disable the second CCD for these games. 16 core, tuned with curve optimiser and SMT off will give the best all round results in a wide selection of games. The 7800X3D will probably be the fastest gaming CPU and will steal the crown from the 7950X3D, however as with the 7950X Vs 7700X, I believe the 7950X3D will be faster once tuned.

@Grim5 I've completed MW2/Warzone 2 testing. I'll put a video up on the weekend, but this is the ideal 7950X3D configuration. 16 cores enabled, SMT off. Renderworkercount in COD set to 6. I tested 7, but 6 was faster overall. Here are a detailed look at the results. Pay attention to the CPU FPS, not GPU or overall FPS.

MW2 Benchmark 4K Basic Preset
x2 CCD = 16 cores enabled
x1 CCD = 8 copres enabled
Render = The RenderWorkedThread Count used for MW2 6 = 6 CPU worker Threads etc
7950X3D + PBO + Curve Optimiser

This is why I want the 7800. Having to disable/enable worry about parked cores…the whole thing is so inelegant. It’s like some kind of computer oddity from two decades ago.

But you don't have to do anything ot worry about disable/enable. If the CPU is parking cores itself to an 8-core then you are already at the 7800x3D and then if something uses more cores it un-parks itself and uses those cores as needed. If you want to shift a game from one CCD to another then you can do so via the xbox gamebar if you feel it is not on the optimum core but if you manually pushed any game that is not on the x3D CCD0 then you will loose performance in some titles more than others.

You can enable legacy game compatibility mode in bios and just hit scroll lock to park ecores on the fly. No need to reboot to toggle

I figured that out far too late lol. I don’t like Process Lasso, so that was a God send.
 
@LtMatt @Bencher

Keep in mind that when testing Cyberpunk you should pay attention to the in-game time as that affects the numbers of NPCs active and their routines, so it also affects CPU performance testing. Ideally test between 09:00 - 20:00. Also, performance varies a lot when driving vs on-foot (as well as what parts of the components get stressed).

Great testing tho! I'm loving it. :P

For me the major question has pretty much been answered, and that's that we are now at or above 120 fps in the titles I'm most interested in. The ones that aren't we're talking API (DX11 et al) issues which are unresolvable unfortunately (without a remake). I think something like the 7950X3D will not only crush anything thrown its way this generation, but it will still go hard even for the next cycle (PS6 & co.).

The interesting thing about that slide is its showing performance for the 7950X as if its got a full size iGPU, really?

Have no idea but the updated chart from PCMag says that's what happens in F1 22

Exactly I litereally posted this like 30mins after video done. People are rehashing the same discussion with zero concept or wilful misunderstanding tbh.

Are we in a time loop? This is the same discussion we had about it when the last video was posted where people had a direct quote about why and how it all works.

Not everyone reads pages and pages. Let’s be honest if all posts that are off topic were deleted, there wouldn’t be many left. Once the discussion turns to how much more money AMD has made and how they manufacture their shoe laces and where, it’s turn off time.
 
The tech press didn’t bench it, but apparently the 7900X3D is absurdly faster than the 13900K in Tarkov according to an owner of both CPUs. Tarkov was always quite favourable towards the 5800X3D from memory.

True but it was only 2 pages ago and almost a page long discussion. It just seemed like a few people picking info to start a repeat of the same thing instead of just reading the thread or even glancing at. The day we can have threads on topic and all posts cleaned out proper would be awesome, even this comment ha.

I guess the comparison is this video where its also done in 4k FSR 2.1 in the last segment?

 
LtMatt said:
Yes.

1. Disable Second CCD.
2. Disable SMT.
3. Clean OS, minimal background apps running.
4. 360 AIO +Liquid Metal +100% fan speed.
5.Latest Chipset drivers, game mode enabled in windows and Game bar updated and enabled
6. Tuned CPU, using curve optimiser -28 all core. PBO enabled, max power limit scalar x10.
7. Tuned memory, 6200MhzC28 64GB dual rank, with FCLK at 2167mhz.
8. BIOS memory options, Disable memory power down.

Awesome, thanks! I think I'll need to tweak the PBO settings. Did you test the -28 with P95 or something to verify it's stable? With my previous 5800X there was no way I would have gotten that much of a undervolt.

I use y cruncher 1-7-0 to test cpu stability and 25 runs of TM5 1usmusv3 and 5 runs of Anta777extreme profiles to check stability.

sadly this is AMD for you. make everything more hassle than it needs to. its baffling they still cant work this out. every product the same. just make it work without the extra messing about. its why most just pick intel nvida cause you plug in it works!
