Info 64MB V-Cache on 5XXX Zen3 Average +15% in Games

[Kedas]

Well we know now how they will bridge the long wait to Zen4 on AM5 Q4 2022.
Production start for V-cache is end this year so too early for Zen4 so this is certainly coming to AM4.
+15% Lisa said is "like an entire architectural generation"

AMD Ryzen 7 5800X3D Review: Gaming-First CPU

Making CPU cores faster rather than adding more cores is the best way to boost PC gaming performance. That's why AMD has supercharged their 8-core, 16-thread CPU...

AMD Ryzen 7 5800X3D review

It's time for another ZEN3 review, this time something extra special for gamers. It's the much-discussed Ryzen 7 5800X3D. The CPU, which is on many people's radar, features eight cores and sixteen ...

HWUB review is live!

OK, not gonna lie... this is unexpected. 12900K with DDR5 outperforms the 5800X3D in games. The gains between DDR4-3200 to 3800 is also negligible, though I guess the larger cache somewhat negates the benefits of faster RAM.
Things just got slightly more awkward with AMD's 'fastest gaming CPU' claim. At least it is 15%+ faster than Zen 3 overall, so I'll give AMD that.Thoughts?

Btw, here is the techspot (written version) for those who aren't fans of video reviews: https://www.techspot.com/review/2449-amd-ryzen-5800x3D/

I'm not sure how many of those budget conscious gamers will now be willing to spend $450, basically 2-3 times the outlay of their original Zen 1/2 CPUs, when a $200 Ryzen 5600 gets within ~15% of the gaming performance of a 5800X3D and realistically, at higher res or with more mainstream GPUs, the gap closes further.

It depends on what games you play. On borderland it gives up to 46% Boost over 5600X, 43% over 5800X, and 15% over 12900K/KS

 

[Borealis7]

I can't understand some people here. Yeah Nobody games at 720P(not the point of the benchmark by the way), And whoever plays at 4K is not bottle necked by the CPU but by the GPU, pair any decent CPU of the last 4 years with a 3090 Ti and be happy..

But this CPU, It's the Gaming King at 1440P where most people would agree that is a very impressive piece of technology and from available data, It beats the 12900KS at 1080P and 1440P(TPU and Chancho Gaming)

and for any other purpose, its not that good. (i.e. anything other than 1440p gaming)

 

[nicalandia]

The performance boost is impressive

 

[Timorous]

Holy -redacted- at the factorio result. 56% faster than 5800X and 26% faster than the 12900KS with DDR5 6400.

I like that techspot included 4x8 3200 CL14 memory since that is what i'm using and 3800. There isn't much of a gain from faster memory on Zen 3 compared to Zen 2.

 

[Timorous]

GN tested Troy and the 5800X3D does really well there as well.

Good signs for the games I play so will be buying this on launch, hopefull. Have a meeting that ends at what I assume will be the 2pm UK sales go live point so that might mess it up if it gets dragged out.

PCGH got some very interesting results. Power consumption in games (CPU only):




Performance with power consumption from above:



70W vs. 186W (in games!) for the same performance! And that's already with Intels newest architecture on their "new" process node while it's still N7 and Zen3 for AMD... Crazy.

ANNO! Need to go check how that does.

Was just about to say something about that. Clearly the clocks are reduced because of the heat. But it does make it super efficient. That might be part of the reason why even in games it can be hit or miss. But when it hits, it does real well.

I am sure the 12900KS has a sweet spot for efficiency if you clock it down to 4.7 or so... Except it was pushed beyond reason to take some of the Thunder away from the 5800X3D Gaming King.

Are we just going to pretend no other Intel CPU exists that uses less than 186W? My 12900K feels neglected...

Seriously though, those are some great efficiency figures. The problem is that high end GPUs are soaring past 400W these days... saving a few watts off the CPU is hardly going to affect your power bill.

 

[nicalandia]

Just look at this and tell me with a straight face that this is not the Gaming King.

 

[Timorous]

LTT did a Civ 6 turn time test. No improvement over the 5800X there and ADL is faster. Guess the data set is small enough and it just need raw IPC and clockspeed for that one.

Impressive! But why is the 12600K faster than the 12900K?! Something is off there, surely.

But OK, since you said that, I'll bite. I can't, in all honesty, call the 5800X3D the undisputed 'gaming king' - and no, thats not because I own a 12900K and don't want to relinquish the crown! I was fully expecting the 5800X3D to beat it in the majority of games. And it does... with DDR4. But those DDR5 numbers... yeah DDR5-6400 is crazy expensive still, for sure. But if you are going to argue 'halo gaming, fps is life, cost be damned' then surely a 3090 Ti owner would get the 12900K / DDR5 over the 5800X3D?

People should look it at this way... Games that like Cache. The performance improvement is MASSIVE... For games that don't you can still fall back on the fact that is a Zen3 uArch and that is Top of the line gaming uArch anyways(behind Alder Lake within single digit in games but above Rocket Lake, Skylake, Zen2 )

Yea, was hoping Civ 6 would see a gain but oh well. The Troy, Anno and Factorio results give me some hope that the cache will help in games like Stellaris that I also play. Wonder how it will do in Path of Exile / SW:TOR. Guess I will have to find out. Maybe that person who does the WoW performance testing can get hold of one and we can test it there.

Also in some games the lows were really impressive and the MSFS result at LTT was damn good as well.

EDIT: Oh and the gain in RiftBreaker was also really good too vs the 5800X. Split the DDR4 and DDR5 based 12900K systems.

Not every game is optimized for Cache$.. Cache is very expensive on CPUs(for both the price and Die area), but now that stacking Super Dense SRAM L3 dies vertically is a Reality. I can see many games developer taking a chance with the tech. I believe that in 5 years from now the 5800X3D will be compared to newer CPUs and newer titles to see if Game developers took advantage of it

It beats the 12900K soundly at 1440P and 4K where CPUs are not the bottle neck

I doubt that will happen. Devs will optimise for consoles because that is where the engines get used the most.

Who is to say that next gen Consoles are not getting 3D V-Cache in the future?. To be honest, if there is a single segment in the industry that needs more Cache. that it's Consoles

There is no 12900KS in those comparisons though lol. I'm guessing you mean the 12900K. Close enough.

Again, I have to question those charts when the 12600K is beating the 12900K in gaming. I just can't take those results seriously.

What we have learned from the recent reviews is that the 12600K is really a good Gaming CPU..!
