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"

The world's Fastest gaming processor

AMD Announces Ryzen 7 5800X3D, World's Fastest Gaming Processor

AMD today announced its Spring 2022 update for the company's Ryzen desktop processors, with as many as seven new processor models in the retail channel. The lineup is led by the Ryzen 7 5800X3D 8-core/16-thread processor, which AMD claims is the "world's fastest gaming processor." This processor...

@nicalandia they said put your clocks ahead an hour, not a month

 

[Timorous]

So with the announced 300 series support looks like I am getting a 5800X3D as a last hurrah for my B350 system that has had a 2200G in it for the last few years.

Should be a reasonable CPU upgrade, 2x the cores, 4x the threads at least 50% IPC and higher clocks to boot.

On his channel, Ian said that last he heard the 5800X3d would be overclockable, so maybe those reports of it not being overclockable were a bit premature.

My X570 Xtreme bios went from having OC features pre F35 bios , F35 removed OC features, F36a has them back.

F35 bios was released 01.28

More than a month away, too late...
And the availability... I can already see only a few lucky ones getting one and all the negative reaction from all the others that waited so much for this thing, along with the collective disappointment at the performance.
There's no way this will be more than a curiosity at this point, right? Right?

Depends. It might be faster than Raphael in some games. That plus a cheaper platform and cheaper DDR4 could make it a popular gamer CPU for anyone that doesn't stream on the same box.

Since When having Zen3 can disappoint anyone? At gaming or otherwise?

I will be CRUSHED if I cannot get the 5800X3D. I've been waiting so darn long for another big cache CPU. But if it is near impossible to buy for MSRP, the wait for Zen 4 will begin...

 

[DrMrLordX]

Odds are decent it'll be out by August.

 

[igor_kavinski]

AMD could have their best ever April 1st joke. Flood the market with Zen 4 CPU's without any accompanying motherboard. I would definitely do that if I were AMD CEO. I would tell the world that the CPUs were ready so we decided to just put them on the shelves. However, motherboards are still undergoing validation so everyone has to wait.

 

[igor_kavinski]

I will be CRUSHED if I cannot get the 5800X3D.

Don't worry. There's no way AMD will deprive you of the CPU of your dreams. If they do that, I will curse them!

Eh, at this point I'm debating returning my 5900X and just waiting another 1-2 years.

Can someone with more knowledge on TSMC 7nm HD process works Help me out here?

According to TSMC their High Density optimized SRAM cell libraries are 0.027 um^2. But if that was the case the L3$ Die on the 5800X3D which is about 36 mm^2 should have 256 MiB of ram..




I am basing my math on Anandtech article about TSMC 5nm(where they calculate um^2 x Megabit to get mm^2 die area)

Early TSMC 5nm Test Chip Yields 80%, HVM Coming in H1 2020

www.anandtech.com

I think that the numbers posted by Anandtech as far as mm^2 per Megabyte are off..

Here is something better, but still is half as Dense as the L3$ 3D Cache.

How is TSMC pulling the L3$ IO Die Densities? It boggles my mind.

 

[BTRY B 529th FA BN]

Just seen Yuri Bubliy's Twitter post right now. Dated March 10th. Seems heat is the issue with OC'ing the 5800X3D according to him

EDIT: read more of the thread and he has some discredit to his name so take it with a grain of salt i guess

It's 2017 AMD Makes an Impressive Comeback, Their Top Performer 1800X is such a world class performer in Workstation class apps because at gaming is not that great. People Praises AMD..





It's 2022, AMD announces the 5800X3D the gaming King processor at $449 and a very good gaming line up(5600 for under $200) that will work on budget AM3 MB during a Pandemic, Chip Shortages, Miners and people still go out of their way to complain about the price?

For what it's worth, the price can't be looked at in a vacuum. In 2017, the equivalent Intel offering was $1000. Meanwhile, Intel has very compelling offerings today, on both price and gaming performance. People just moan about AMD's price because of a few reasons: 1) People still see AMD as the company that gives them a budget-friendly, bang-for-buck option, and when that's no longer the case they whine and moan, and 2) While you can get a lot of performance for the same absolute dollar amount today than 5 years ago, the pandemic and "inflation" has hurt people's pockets and disposable income far more.

 

[biostud]

Who complains about the cost of CPU's these days? You can get reasonable priced CPU in every segment, but obviously the top processors are never those where you find the most value, and it never has been. The cost of a CPU fit for a gaming rig has if anything decreased over time, as the video cards are what limits your fps in gaming in most cases. For a modern gaming computer the cost of the video card is likely to be far greater than the CPU.

 

[gdansk]

I think prices, at present, are reasonable. But AMD was late to the value options which is a bit concerning in my eyes. It may be a function of their limited production capacity but still it is overdue.

 

[Panino Manino]

It was supposed to be "Zen 3 AND MORE!", not it's "just Zen 3 and more".
I can't see this anymore as anything other than just a curiosity.
K6-III+ was better more exciting than this!
I hope to be wrong but I'll stay here expecting the worse until proven wrong.

 

[nicalandia]

I hope to be wrong but I'll stay here expecting the worse until proven wrong.

What could possibly be "Worse"? I just don't get your point here.

Zen3 is a few percentage behind than Alder Lake in 1080P testing and about even on Higher Resolution gaming. Are you expecting this B2 Stepping to be worse?

 

[coercitiv]

So now we know what and why:

General rule of thumb: If you want to achieve higher frequencies you need to lower density. So even if the High Density optimized SRAM cell libraries are used for the X3D SRAM you'd want to lower the density until it can manage to handle a CPU potentially running past 5 GHz.

According to AMD, the V-Cache only helps in gaming applications. "Regular user workloads" do not provide enough cache pressure to see a benefit. Milan-X sees a benefit because it does not run "regular user workloads".
