Discussion Zen 5 Speculation (EPYC Turin and Strix Point/Granite Ridge - Ryzen 9000)

[DisEnchantment]

Speculate at will

 

[igor_kavinski]

how is souped up laptop APU in any way related to semi-custom?

Couldn't they replace the APU's LPDDR5X with GDDR6?

BTW, howz the culture at AMD? Do they cross-pollinate a lot?

they do, a lot of bees work at AMD

I heard Intel has a pollination problem. It got BK fired (eventually).

Good luck with that...

 

[adroc_thurston]

Really not that hard at all.
Just pointless.

Console peasants deserve better!

tl;dr

At this point, how many more CPU drop-in upgrades can X670 or AM5 support? I'm assuming the 9xxx series would be the last for AM5 Desktop

Sony PlayStation 5 Pro teased with PSSR (Spectral Super Resolution) support - VideoCardz.com

Sony PS5 Pro and PSSR According to the presentation page revealed by Moore’s Law is Dead, the next-gen PlayStation console should support a new version of super resolution technology. It was revealed that the alleged PS5 Pro GPU has machine learning capability of 300 TOPS with 8-bit integers...

PS machine learning. Could this mean Strix Halo will be used for PS5 Pro with maybe 20GB RAM?

How did you come up with that?
From when does Strix Halo have a 60CU IGP?
And you can't pair 20GB with 256-bit bus and let's not forget Strix doesn't use GDDR6.

Since it's AMDs DDR5 platform I expect it to be the platform for every future generation until they adopt DDR6. Which generation that will be is the question. Zen 5 is definitely on AM5, Zen 6? Unclear. I'm not sure DDR6 will be ready by late 2025/early 2026.

Anything custom is possible but unfortunately they won't be going with Zen 5 due to compatibility reasons so it's gonna be boring Zen 2.

Or cost effective.

Intel supported DDR5 roughly a year before AMD, but the price and performance benefit made it less than appealing. But they had DDR4 support for the same CPUs. So even if AMD could make zen 6 for AM6 and DDR6, then it is not necessarily a good idea if they want to sell a lot of systems.

Yeah they would be mad to repeat the expensive Zen 4 mistake of launching a new platform that is too expensive compared to their existing one. AM4 is still going strong and AMD is in no hurry to forcefully make it obsolete. Sales of AM4 may only start slowing down once DDR4 stocks start dwindling.

see that's the thing.
DDR6 is not coming to desktop.

Zen 2 is also quite small. If it provides enough CPU capability to exploit the GPU segment, then why change?

Area/power efficiency but Sony is extremely anal about backcompat in a weird way.

Nothing is impossible with a can of beer and a hammer.

Why not?

 

[adroc_thurston]

Why not?

Because it's a server memory and you'll be enjoying LPDDR instead.

 

[CakeMonster]

What is even LPDDR on desktop? Same size DIMMs, just lower voltage? I'd be really surprised if more than that was changed in time for Z6. Definitely not expecting DDR6 that soon anyway either, whether or not it will be for desktop.

 

[Thibsie]

LPDDR is usually there faster than plain usual DDR I believe.

 

[Glo.]

As long as we get 256 bit bus on mainstream solutions, and unified memory architectures, because of it - Im fine with anything AMD and Intel brings.

On the CAMM2 form factor?

LPCAMM2/3 yes.
