AMD demonstrates Ryzen 9 5900X prototype with 3D V-Cache stack chiplet design

I don't believe this. It says Prototype. And the thing is that prototype may not enter into mass, serial production!
Maybe it's just an experiment.


AMD had never used previously the word "prototype" in their presentations.

Seriously, what is the matter with you? Do you have a selective memory, or are just sticking your fingers in your ears to block out the sounds of facts rebuffing your idiocy?

Lisa Su literally said at Computex that 3D stacked Zen 3 CPUs will enter mass production at the end of the year. i.e. this year. Are you calling her a liar? Do you think he is stupid enough to make such a statement if it was not going to happen?

Are you really this mentally ill?
 
She said something very different, though. Unless she speaks about several different "Next-generation" products:

"
We remain on-track to launch next-generation products in 2022, including our Zen 4 processors built with industry-leading 5nm process technology and our RDNA 3 GPUs.

No mention about any Zen3+ in that article, nor in any newer one.

What's the codename of this? Every new generation has a codename.
The 5900X is Vermeer, what's this, then?
Do you even know what name it has?
"5900X prototype with 3D V-Cache"?!

Sounds very strange.

Less strange than you sound right now. Just make up a code name if that helps you with reality.

The first post of the first page has all the details you need.
 
Call it non-existent, then :D

Q- How much of the performance gains delivered by AMD’s Zen 4 CPUs, which are expected to use a 5nm TSMC process and might arrive in early 2022, will come from instructions per clock (IPC) gains as opposed to core count and clock speed increases.

Bergman: “[Given] the maturity of the x86 architecture now, the answer has to be, kind of, all of the above. If you looked at our technical document on Zen 3, it was this long list of things that we did to get that 19% [IPC gain]. Zen 4 is going to have a similar long list of things, where you look at everything from the caches, to the branch prediction, [to] the number of gates in the execution pipeline. Everything is scrutinized to squeeze more performance out.”

“Certainly [manufacturing] process opens an additional door for us to [obtain] better performance-per-watt and so on, and we'll take advantage of that as well.”

Zen 4 might be pulled forward to early 2022.
 
I genuinely question the moderation of these forums when 4K goes on these insane tirades. Literally thread trashing, trolling and outright disruptive behaviour, yet nothing is ever done about it.

All right. Now prove that any new AMD chip actually exists, show some benchmarks of engineering samples, please!

Now 4K why does anyone have to prove anything to you. Granted the below is about EPYC but proves 3D Cache is working and in use on ZEN 3 cores. Even better it is taken from your favourite sauce

AMD EPYC Milan-X CPU Specs Leak Out - 64 Zen 3 Cores, 280W TDP, & Insane 768 MB Thanks To 3D V-Cache Technology
The AMD EPYC Milan-X lineup is no mystery, we already saw the chips listed at several retailers & preliminary specifications were listed too. Now we know the exact core clocks and the amount of cache that the new Zen 3 chips with 3D V-Cache vertical chiplets stacking technology will offer for server customers.


AMD EPYC Milan-X server CPU lineup will consist of four processors. The EPYC 7773X features 64 cores and 128 threads, the EPYC 7573X features 32 cores and 128 threads, the EPYC 7473X features 24 cores and 48 threads while the EPYC 7373X features 16 cores and 32 threads. The models along with their OPN codes are:

  • EPYC 7773X 64 Core (100-000000504)
  • EPYC 7573X 32 Core (100-000000506)
  • EPYC 7473X 24 Core (100-000000507)
  • EPYC 7373X 16 Core (100-000000508)
The flagship AMD EPYC 7773X will rock 64 cores, 128 threads and feature a maximum TDP of 280W. The clock speeds will be maintained at 2.2 GHz base and 3.5 GHz boost while the cache amount will drive up to an insane 768 MB. This includes the standard 256 MB of L3 cache that the chip features so essentially, we are looking at 512 MB coming from the stacked L3 SRAM which means that each Zen 3 CCD will feature 64 MB of L3 cache. That's an insane 3x increase over the existing EPYC Milan CPUs.

Now i know you are probably going to ignore this or spout something about it not working on desktop or it will not happen. Fact is we do not know what AMD will call the ZEN 3 desktop parts that have 3d Cache, maybe they will just stick XT on the end of the current models and bump the clocks a little to go with it, i do not believe the last gen XT range had a super special codename but i could be wrong. Either way i believe if AMD see Alderlake as a threat we will see these soon

This thread is awful to read now, I've got 4k blocked so 90% of this page is hidden posts

Had them blocked for ages now, no idea why they continue to let the user post, and create threads etc. They bring the forum down, and waste bandwidth for others. I honestly prefer the rabid fanboys, to the almost incoherent drivel.

agreed, zen3+ vcache may be cancelled since it may make zen4 look like a pointless upgrade needing new mobo and ddr5 for a 5% increase in ipc over what zen3+ would have offered.
