Review Zen4 3D review thread

[Hitman928]

Thread to focus on Zen4 3D cache CPUs.

New gaming king (as most expected), though the 2 CCD 7950x3d does seem to have issues with some games, more than I would expect of it getting stuck on the "wrong" CCD. I imagine it will get cleared up with subsequent updates but we'll see. Simulated 7800X3D showed no such issues and overall has the gaming lead (real product might be slightly slower though depending on in game clocks).

Computerbase also has the 7950x3d as the gaming champ. They (and TPU) also show that efficiency while gaming is extremely good.

Ryzen 9 7950X3D im Test gegen 5800X3D und 13900K(S)

Zen 4 3D ist da. Im Test erweist sich AMDs Ryzen 9 7950X3D gegen 7950X, 5800X3D und Core i9-13900K(S) als schnell und effizient.

Just to toot my own horn a little, it landed spot on with my prediction of fastest gaming CPU but not significantly so over a 13900k on average, but with much higher efficiency.

Additional reviews, will add more later.

Have to say I was thinking it'd be faster in games... but when it wins, it wins big time.

HWU did see a decent additional performance gain "emulating" the 7800X3D. Guess Process Lasso might be worth using.

Looks like the automatic scheduler algorithm isn't working correctly 100% of the time. TPU found setting to "prefer cache CCD" in the bios can have a large effect on some games.

 

[Hitman928]

Factorio results for those interested in those types of games. It is complete domination though another game where you would want to set BIOS to prefer cache CCD if you get the 7950x3d.

Factorio numbers are bad.

Being a few percents better than 13900K in gaming while consuming half the power, that is a very good achievement. (from Computerbase data)

Thanks, added to OP.

For Factorio, see HWUB results. It gets stuck on the wrong CCD for some reason (or maybe even goes back and forth). Hopefully this is something that gets worked out with time but you can set to "prefer cache CCD" in the BIOS in the mean time which should fix it.

Looks like they have some room for improvement on the scheduler since setting it to prefer cache helps.

7950X3D power consumption shines, as expected with a 120W TDP. Uses less power than a stock 13600K at full tilt:

It's the same story as with the initial issues during the Alder Lake launch: they need time to cover all the edge cases. The "prefer cache CCD" option sounds like a good patch until the dynamic scheduling is mature enough.

While I've seen a few people go on about Spiderman:remastered and how it uses the e-cores to precompile shaders etc, doing so comes at a significant energy cost. The 7950X3d manages to perform very well for around 85 watts with the 13900ks pulling around 200 watts in comparison. That's 40% of the power usage. THAT is a significant difference.

Seems like 7800X3D will be the one to wait for if gaming is the primary use case. Costs less than its bigger siblings and 13900K/S and doesn't require expensive RAM.

 

[tamz_msc]

So there is a clear consensus that except for a few instances, a single-CCD X3D CPU, i.e. 7800X3D, will be much better for gaming than a dual-CCD CPU with only one CCD having v-Cache.

So why then does the 7900X3D and 7950X3D exist in the first place?

Precompiling shaders is supposed to happen only once, unless you change the GPU driver. Power consumption during precompiling shaders is a non-issue.

[Timmah!]

The top clocks speeds are bit disappointing. Compared to vanilla 7950x graph i mean.
I was bit excited yesterday, but not so sure now. Would love to see more in-depth review concerning tuning, if something can be done about this. Otherwise i will probably stick to that 7950x, since i care more about productivity performance.

Nobody is gonna buy these two for gaming. Usually it is the performance tapering out as you go higher tier that drives ASP. Like Core i5 < Core i7 < Core i9. With these it is the opposite.

It's basically the best desktop CPU by a long shot now. Versus 13900KS, gaming is faster, app performance is the same (more or less) and power efficiency is better by a factor of 2x! Insane perf/watt, I wonder if MTL-S can match this level of efficiency. Job well done AMD!

Meteor Lake doesn't target the consumer desktop market.

 

[leoneazzurro]

7800X3D should be set up for lower boost than 7900X3D/7950X3D cache CCD, so if the results of the 7800X3D are simulated using the 7950X3D there may be some inaccuracy even if it's unlikely the CPU will hit max boost except some edge cases. In any case, 7900/7950X3D behaviour will likely improve in time when newer releases of the drivers will come out, and if someone does also productivity tasks they guarantee higher performance in that regard.

 

[utahraptor]

I appreciate the trouble toms went to in showing stanrdard, expo mem and pbo. Also they did the flight sim people asked for.

13900K and KS still have the best single core performance. They still lead in some applications as Excel.
