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"

So Graph from Techspot 40 games review(They should have added Flight Simulator)

Or Factorio, but if you do this you create the impression that it's faster on average than it really is.

 

[Carfax83]

The fact that the 5800x 3D can gain so much from the extra cache highlights the fact of how much the CPU is hampered by having to wait on memory requests, and also how games can be multifactorial in their dependencies for performance. That Microsoft Flight Simulator uplift is nuts!

The reviews also showed the potency of the Golden Cove core when it comes to raw processing power. Games that depend heavily on CPU processing power like Riftbreaker, the Alder Lake based CPUs with fast DDR5 are just much better performers than Zen 3; even after the 3D cache upgrade.

That Microsoft Flight Simulator uplift is nuts!

Even more nuts when you factor in the possibility that even with a very optimistic 30% IPC uplift, Zen 4 may not be able to match the 5800X3D in MSFS, let alone beat it. Higher DDR5 speeds might help narrow the gap or even overcome it.

I'd love to see some dedicated report about what games and apps are limited by cache size right now and at what cache size or memory latency/bandwidth that may change.

Dang, no listing at my local MC this morning.. 4hrs till store opens

EDIT: AH! Refreshed the page, 5800X3D is listed, signed in, reserved, yay!

Nice to see that they are shipping with this CPU it appears.

Can anyone Please with a $10,000 to spend or that know people in very high places at Phoronix/Serve The Home be kind enough and test MS Flight Simulator with Milan-X 1.5 GiB 3D V-Cache? PLEASE...!

I just ordered mine. £410 in the UK so not too bad.

Here's HUB's 41 (they include flight simulator this time) game comparison between the 5800X and X3D. Not to spoil the video but the 1080p average comes out to 15%, but the more impressive results are in the 1% lows which even see 50%+ gains in a few titles.

 

[nicalandia]

That is the Whole Point of having 3D V-Cache on a CPU to exploit games/apps that benefit from it.

And here is the reason for not including them on the first 5800X3D vs 12900K tests..

Ryzen 7 5800X3D vs. Ryzen 7 5800X: Zen 3 Gaming Shootout

On the menu today is another 40 game benchmark -- actually 41. This time it's the 5800X3D against its spiritual predecessor, the 5800X, to see where that...

Hopefully AMD hasn't put themselves into a corner with gaming performance. If 5800X3D is so much better at games it may undermine their upcoming Zen 4 launch. (for gaming)

I expect Zen 4 to win on average but there might be a few games where the extra cache really helps the X3D so it wins regardless.

Zen4 will be the Superior processor at everything not just gaming. You see on some games the 5800X3D matches the 5800X, the 7800X will be 20% just on IPC, you add Speed on top of that and you will see a massive gain in both productivity and in games. Perhaps a tie in Microsoft Simulator and in Factorio? But on everything else it will be the clear choice

Instead of memory speeds (besides larger L2), isn't the real reason the extra ALU in Alder Lake allowing it to do more work?
(I hope Zen 4 will also come with a fifth ALU, right?)

Zen4 is a Refinement of Zen3, They have kept the same 4 wide ALU

Seems TSMC can have only one 3D stacked manufacturing line at a time. Maybe they have only one fab able to do it.

But does it blend? Can it handle a hydraulic press? These are the questions that need answers.

Please try this 5 minut OC to 4.8 Ghz and see how it performs..

 

[wilds]

Not really a fan of BCLK OC for any platform, but I might give this a go if I am desperate for more performance in a few months. Gonna let some 5800X3D owners really push their CPU while I sit back.
