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.







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.

Those DDR5-8000 speeds on Raptor Lake, that some people were taking for granted? The guy who is pretty much an authority on memory overclocking says it is impossible to have a stable build with Raptor Lake and DDR5-8000

His rant was like me during the first month of Zen 4 release. Over a month after release, with better BIOS versions and buying overkill Hynix A-die memory, all issues have been sorted out. I'm confident my system can run any stability test all day long with the settings I posted earlier in this thread.

I let AC:Odyssey con me into upgrades to get smooth gameplay, not falling for that again. Meaning if Hogshardware or another game doesn't run right on my present setup, I'll dump the game instead of the hardware from now on. At most I'll grab a 5800X 3D down the road.

But what if you know the game is 100% buggy but still persists because nothing else is that open (both in therms of world and in terms of user mods)?

Yes, I am hinting on at the Fallout 4 drawcall thread and the similarly buggy Skyrim (first version was build with a x87 code path - so Bethesda have form for releasing half-finished things).

Yes, it would be crazy to spend big for Zen4 3D plus a GPU with at least 16GB just to play modded Skyrim... but I am almost tempted!

He mentioned the comparison with AMD Zen 4 (as of today). I would interpret his remark as there is a cliff - when it starts and runs, it runs 100% stable, or it does not run at all..

While the Raptor Lake system is like a downward sloped line. As the speed is increased, the stability gradually deteriorates. Another notable Buildzoid comment is the randomness and poor repeatability of the results.

PS: nice results there that you posted earlier.

Looks like the benefits of decent memory (DDR5-6000) + V-Cache stack:
(I wonder how much is contributed by optimized timing on the DDR5-6000 vs. out of the box EXPO timings)

Not saying low hanging fruit, but this shows the large IPC gains available outside of the compute pipeline expansion being discussed for Zen 5.

Linus just wrecked the 7950x3d. Turns out it wasn't the gaming king AMD made it out to be.

Bruh. I would not trust a review from LTT. They have so frequently just messed up their product reviews in the past, I'm not even going to bother watching their video this time around.
What do you think is more accurate, LTT, or the culmination of 15+ reviewer's average data showing the 7950X3D taking the gaming crown over the 13900ks? (3Dcenter.org launch review).

He actually address this in the video. Then proceeds to smash why those 15+ reviewers are wrong.

Those 15+ reviews are wrong, but in the other direction.

Problem is the popular games that really show off how great v-cache is like Civ 6 or cities Skylines or Stellaris or World of Warcraft or Path of Exile or iRacing or ACC or MSFS or Satisfactory or RimWorld and so on and so on do not get benched. On occasion MSFS and Civ 6 gets benched although Civ 6 is a tossup between testing for FPS (pointless) and turn time (actually useful). Also HUB do test ACC regularly which is good.

Point is the 15+ reviews show the x3D as being the fastest in the typical AAA skewed benchmark suites. If suites expanded to include other very popular games and genres the lead would likely grow. Just like we see how much faster the 5800X3D is in Factorio over every other non v-cache CPU.



Obviously in this test the 7950X3D went to CCD1 but look how fast the CCD0 result is and look at how much faster the 5800X3D is than the 13900K. A 27.5% lead in this game. That is a generational advantage and the 7800X3D simulation is even 56.9% ahead.

If more actually CPU limited titles were tested in these 'gaming benchmark suites' then the advantage of the x3d chips would be far far higher than what is actually shown.

EDIT: Bottom line is that if you are a AAA focused gamer who plays at 4K or 1440p with a resolution appropriate GPU then the CPU is less impactful for you. If your gaming repertoire expands beyond the typical AAA fare then chances are there are many titles you play where a potato GPU can manage 4K settings easily and the CPU is the actual hold up. Like playing cities skylines with a 400k+ pop city. The CPU is the component that is crying.

Well stated. For many sims, AMD 3D CPUs body most everything else.

It does not speak well for the industry, that no major reviewer has as of yet, instituted a decent sub suite of sims into their huge gaming benchmark selection. The usual suspects counter by saying who cares? Those games are niche. All game genres are a niche, Lamont! you big dummy! Factorio sub reddit has over 324K members. MSFS is huge as I have written about before. iRacing has an estimated 160K daily players and an install base of nearly 7 million. I could go on. But those in denial will continue to cherry pick outlier reviews to assuage their over sized amygdala.

To me it really doesn't matter which CPU is the "gaming king" as long, as there is competition in the market, different price ranges to choose from and generational improvements, then everyone can choose whichever CPU they prefer. Sometimes there is just too much drama
I will do drama over FUD, on every day ending in Y.

I watched the video myself 2 days ago while preparing dinner. I forgot most of what was said but it has to do with the chips dual chiplet structure causing the processor to sometimes downclock or not use enough power to deliver steady frame performance. His teams results in their new lab is a little strange because they also go for the best hardware reasonably available. In the video the 13900K is paired with 32gb of 6800 ddr5. Most people aren't running that speed and other reviewers will stick to 6000 or 6200 since most intel mobos and 13900k's can handle that speed. Their lab needs fine tuning otherwise it's a best of best scenario. During their initial bad results with the bad processor they got into touch with their amd reps and they stated the performance was fine to their puzzlement. Bad chips be damned but I'm sure there's bios and driver improvement to be made to extract the max potential of these processors.

LTT are so incompetent that they managed to nuke all of their YT channels and lose them to some crypto scammers. Hilarious
Youtube unlists channels that get "hacked". An employee downloaded a pdf file made to look from one of their hardware vendors. This attack method makes a 1 to 1 copy of all browser profiles and sends it to the command and control server. It's been a method of attacking larger businesses, critical infrastructure and government. This is the 10th or 12th major channel to get attacked this way.

There is no excuse for that, they are just incompetent.
