3D V-Cache is coming to AM4 in early 2022 on AM4

1 : Anonymous2021/10/12 15:33 ID: q6otai

In the recent 5 years Later video uploaded by AMD, Robert Hallock confirms that there will be Zen 3 CPU's featuring 3D V-Cache on AM4 in early 2022

Here's the link to the part in the video:

Finally, actual confirmation! My waiting has paid off.

3 : Anonymous2021/10/12 17:34 ID: hgdn1t9

I have mild buyers' remorse about my 5800X, but realistically I know that it's a bonkers powerful CPU and already more powerful than I need.

96MB L3 cache tho...

ID: hgdswhf

It all depends on what you were running before your 5800X and ask yourself, could you've waited until mid 2022?

I was still running a Phenom II X6 and definitely COULDN'T wait any longer 😀

ID: hgdwiiy

And a year after that something even more powerful will be released. There’s no point waiting for new tech or you’ll just be waiting forever.

ID: hgelfyw

Similar boat here. I updated from a Phenom II X4 to a Ryzen 5 3600xt. I knew Zen4 was coming but I don't even remotely regret upgrading a few months ago.

ID: hge8503

And that's where we disagree. My Phenom is doing great

ID: hgdt569

because at some point next year you can get a processor that is at the very very best and likely only in gaming 15% faster ? I will take a wild guess and say the average uplift in performance is likely closer to 5-10% and not 15%.

surely the product of interest is Zen 4 with AM5 and DDR5 etc with a large performance bonus ?

PCIe 5.0 etc.

ID: hge6qok

Oh christ yes, I'll be disappointed if this 5800X doesn't last me at least 6 or 7 years. I got 7 years out of a Phenom 965. I'll probably run this CPU until the motherboard dies.

By then we'll be looking at whatever the generations after Zen4 bring us. Heck, we might be talking about ARM vs RISC...

cant wait to buy the 8 core one

ID: hgdpa0p

did they actually confirm it's coming to the 8 core ? they only said high end zen 3 so that might be 5900x and 5950x

ID: hgdptpd

Or just Threadripper.

This is why I chose to go with the 5600X instead of the 5800X even if my budget could accommodate the latter. I would rather stay with a mature, stable platform than deal with the teething issues of a new one and was comfortable sitting on AM4 for a number of years. Given that, I didn't want to go all out with the initial release of Zen 3 and wanted to see what Warhol would bring to the table. Though Warhol didn't materialize in the form we expected, I'm going to be very interested in what Zen 3D ends up being.

I'll probably up my core count when upgrading to Zen 3D as well. AMD likely can't overcharge with the rumored performance of Alder Lake, either. It was a gamble at the time, but I'm glad I went with the 5600X.

ID: hge4ext

I definitely wish I went 5600x over my 5800x.

The extra heat is just swirling away in my case throttling my gpu

That cache will certainly unleash some cache bottlenecks that ryzen desktop parts might had, but I don't expect a lot of improvements. In layman terms, the cinebench test scores will be very similar with or without v-cache. The gaming performance will be improved though.

ID: hge7218

on intel side cache stacking will for sure unlock performance because cores were having to constantly access RAM due to low amouts of cache where APUs will see biggest benefit

but for AMD cache stacking means that latency penalty is even lower because cores do not need to visit slow RAM hence why unification of L3$ was a 25-30% uplift from zen 2 to zen 3 especially in gaming

7 : Anonymous2021/10/12 15:39 ID: hgd6amv

Will it be APUs with 3D VCache?

ID: hgd6vwl

Despite APU's probably benefiting the most from it, I doubt it.

I would assume its just a 5600X, 5800X, 5900X and 5950X with 3D V-Cache and maybe some higher boost clocks

ID: hgdlexm

My money is on just the 5900X and 5950X getting V Cache. Gut feeling says yields are going to be sorta low at first and you’d want your highest margin parts to be the cutting edge

ID: hge61iq

I wouldn't completely rule it out for APU's. AMD have been pushing pretty hard in recent years to grow their laptop presence so if it helps them with a performance & efficiency boost on mobile platforms expect them to go for it in my opinion. It'll certainly take 6+months longer to arrive I would imagine though.

ID: hge2mr6

Unfortunately doubt they'll do it because it'll cost more and APUs are generally low cost parts. It'd be amazing for them though

ID: hge5n9j

Amd won't release a vcache Apu anytime soon. Their current APUs already have their cache cut in half compared to their non-apu chips. And it doesn't fit the market segment either. It would increase power usage in mobile, desktop users would get a discrete GPU and non-apu Ryzen instead, and DDR5 will give a boost to APUs shortly.

We could see vcache in APUs in performance laptops once DDR5 matures in a few years.

Wonder how it'll stack up against ADL which seems to have around a 20% single core uplift (based on leaks) over RKL.

ID: hgel9g0

Large last level cache doesn’t help most workloads that much after a point. For example your cinebench score likely won’t improve at all. But gaming is kinda special in how much it likes to do unpredictable memory accesses that benefit from large last level cache to reduce main memory accesses. Most applications are rather predictable and the cpu has likely prefetched the data to L1 before it’s needed.

So in short your gaming performance will likely increase significantly but general applications likely not much if at all.

That late? What like 8mo before zen 4.

10 : Anonymous2021/10/12 19:04 ID: hge07z2

Nothing new. This simply aligns with AMD's comment about starting the production at the end of 2021.

11 : Anonymous2021/10/12 19:08 ID: hge0udx

anyone has a suggestion whether it’s Worth waiting for a 3D V cache 8/16 cpu? And also price range? 400€ would be the max I would pay for. I could buy a 5800x now for about 360€

ID: hge28eo

They might not even release a 3D V-Cache 5800X version. It's very possible that this is for 5900X and 5950X only. We don't know.

ID: hge4k3y

Don't expect the new 8 core with V-cache yo be less than what the 5800x was on release

12 : Anonymous2021/10/12 16:24 ID: hgdctg5

Am I being too optimistic hoping this will be supported on my B450 Tomahawk (non max)?

ID: hgdl834

Yes and no. Technically B450 can absolutely support it. It’s just Zen 3 with more bits. Will AMD lock the AGESA update down? Maybe. Maybe not.

ID: hgdmojf

If not then I'm sure the 5800xt will be sub 350 USD by then so it'll work out one way or another.

ID: hgdhisv

It will yes.

13 : Anonymous2021/10/12 17:24 ID: hgdljfi

Am4... Though correct I figure that they will only be supported with a x570 board. Seeing they already had to "force" zen 3 to work on x400 boards.

ID: hgdqe2x

Pretty sure that B550 will also.

ID: hge1hp0

Yea should have said x500. I hope they work for the x400 series but I doubt it, at least officially.

Seeing it can run a zen 3, a deviant of it should be able to run it as well. Unless there's some hardware specific things it needs, besides the top size

14 : Anonymous2021/10/12 19:10 ID: hge142e

PLEASE don't be Pro processors...

15 : Anonymous2021/10/12 19:25 ID: hge3c99

Any idea on mobo support? Likely just 550 and 570 I’d bet.

ID: hgecm0b

I wouldn’t hold my breath for any other chipsets. And I’m basing this off of nothing

16 : Anonymous2021/10/12 17:43 ID: hgdod1n

Don't get your hopes up til you see numbers. Depends on the game and settings that massive cache might not be beneficial or a huge boon.

Does anyone know if it's a contagious cache or is it split like Zen2?

ID: hge6xdh

It's a single cache and there are some per-game numbers, both of those were posted on day 1.

17 : Anonymous2021/10/12 19:53 ID: hge7gvc

I heard PRODUCT not productS. So only 5900X?

I kinda want a 5800x with v-cache, wouldn't that make the most sense for gamers? Also alder lake is coming this year..

18 : Anonymous2021/10/12 20:16 ID: hgeav4j

I'll take a 16 core one thanks

19 : Anonymous2021/10/12 20:43 ID: hgees94

I imagine it's a filler CPU series and a testing ground for the actual stacked chips that will come later. Still a beast of a CPU when all is said and done.

Coming to AM4 on AM4

21 : Anonymous2021/10/12 21:17 ID: hgeju79

Hmm, skipping regular Zen 3 looks to be paying off. Can't wait to get the 12 Core SKU

22 : Anonymous2021/10/12 21:49 ID: hgeod73

Been hemming and hawing, so I think I'll just wait for it.

23 : Anonymous2021/10/12 21:54 ID: hgep1tn

400 series will be dropped on final AM4 3d stack skus and not support as we got blocked x370(300 series) users from zen3 CPUs.Thanks Asrock team release the leaked bios and we got support at least with agesa.

24 : Anonymous2021/10/12 22:02 ID: hgeq6ha

thanks for sharing, it seems they were really hammering during this interview the ~15% uplift in games and it's obviously a direct answer to a very promising alderlake cpu family. I will be honest, i never really expected for amd to release another am4 cpu lineup and im pretty sure it only happened because intel looks very good with its upcoming cpu generation.
