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"

 

[leoneazzurro]

The video is quite interesting for many other things. There is also the confirmation of Zen4 launch later in 2022, as well as the implicit confirmation that (probably with Zen4) AMD will start to use ML accelerators on its CPUs. And a great focus in improving the power savings with a power management framework.

People put way too much faith in 'leakers'.

 

[leoneazzurro]

Well, it depends on the leaker. Kitty Yuuko is the only one saying that.

Not saying that some leakers don't have legit sources and get a lot of things right, but even the most accurate ones get things wrong. Some people seem to start trusting leakers as if they are AMD project managers once they get 1 or two things right, even if what the leaker says is in direct contrast to an official AMD announcement. Just like fortune tellers, people also tend to only remember when they get things right and forget all the times they were wrong. Everyone should be cautious in believing what any leaker says is my point, no matter how good their track record may be. I think most people on this forum know as much, but it was just a general statement after reading that twitter thread.

The AMD video also confirmes PCIe 5 on the AMD A5 platform in 2022 🙂

Hm, this makes no sense especially after earlier Computex presentation.

But it makes sense, if 3D V-Cache is too expensive+AMD intends to launch the Zen 4 Raphael APU earlier than expected.

I laughed so hard when I saw this Tweet because I knew exactly what it was all about.

The conclusion of the whole mess is: XT for OEMs, V$ for DIY (plus some XTs as well probably)

It also indirectly confirms more clocks from new nodes and architecture. Interesting, as some here were expecting stagnation or regression, saying that, marketing can still spin it as more clock (on mobile) but peak turbo lower.

The XT has more been for the higher wattage parts. But the idea that Zen 3D is too expensive for OEMs sounds right.

The worshipping of anonymous Twitter accounts or clickbait YT'ers is frankly making me take long breaks from hardware content rather than engaging more in the community.

Looking at patents is a decent way out of that if that's your cup of tea.

 

[Joe NYC]

Uhhh

Does TSMC even support stacking on N6 yet? N5 isn't scheduled until Q4 2022.

Yes. Both N6/N7 stacking is H2 2021 on TSMC schedule.

The one and only leak of Threadripper Zen 3 is on B2 stepping. And Threadripper has higher power budget, so you may be onto something...

The pre-B2 stepping Zen 3 is being phased out completely. Has nothing to do with Threadripper. If what uzzi says ends up happening, all that means is that any Zen 3D models are going to be too pricey for OEMs.

lol +1.
Especially since AMD has changed its policy about the pre-release product since Zen, we could barely know anything ahead of release date, that said AMD has tried its best to not leaking anything. Just keep doubts when see something 'leaks' about AMD product.
On the contrary Intel seems to not holding new toys as tight as AMD did, very large amount of leaks bursted out, but still some of them could also be clickbait or inaccurate. This is all my feeling recently.

It's less about pricing and more about focus methinks. AMD just lacks the SoIC bandwidth to feed the OEM, DIY and server markets all at the same time. The former just happens to be the one where V$ will have the least impact from a marketing perspective, so it gets the chop.

At the end of the day, pricing will inevitably be dictated by whatever the market deems to be competitive. It's not like there's any chance of AMD losing money on the lineup, even if they have to be aggressive on pricing.

What? No V-cache CPU in 2021? *GROAN*

if you buy Milan-X you can have it :-D

I think I know why Intel has not poached the 2 AMD marketing clowns "celebrating" AMD loss of performance leadership...

Looks more like AMD won't be marketing Zen3D to OEMs.

Makes a lot of sense to be honest. They're looking for the cheapest products bought en masse, cheaper than tray pricing. AMD wouldn't do that for the cache chips, tray pricing or cheaper.

As few of us speculated here, AMD apparently cancelled Threadripper Zen 3

I think that AMD massively screwed up the TR lineup since they switched Socket with Zen 2, then released TR PRO matching most of EPYC features. Too much product overlap going on there. If I was a Zen 2 TR user I would be angry that AMD left me without upgrade path, but it makes sense to unify everything behind TR PRO than to have Socket 754/939 coexisting all over again.

Yeah, the Threadripper platform / SKUs are quite illogical. You could buy 16 core TR on 8 channel platform, but the 4 channel platform, the minimum is 24 cores

Different markets. The TR Pro's competitive product from Intel is Xeon W. The regular TR is Core X. A 16 core TR isn't going to sell much now that the mainstream platform goes up to that.
