Question Zen 6 Speculation Thread

[DrMrLordX]

Point being is that 96M is already enough for hot data, and mem hits won't stop until games fit directly into cache (which they won't).

Nethack to the rescue!!! Seriously though, people used to do some really innovative stuff in tiny amounts of memory. I remember someone doing an (admittedly gimmicky) entire first-person shooter that would fit in 640k. It would be interesting to see what modern developers could do with a ~96MB limit.

They don’t?? IGPU is reason why AMD has Sony and MS contracts.

No it isn't. AMD didn't provide iGPUs to those companies for their consoles.

Excellent observations. Shows there is a lot of brand loyalty, enduring instability of their (loony) tuned systems, up to a point of ridicule and surrender (with Arrow Lake).

In the meantime, there is also a lot of deferrals of purchases, until their favorite vendor releases a CPU that is not laughable. So, you will see people hanging onto their Alder Lake, Raptor Lake as long as they can, arguing that CPU performance does not matter, trying to hold out for Nova Lake.

Which, means, there will be a lot of pent-up demand when Nova Lake is released, and margin of Zen 6 vs. Nova Lake will matter. If it takes 2-hi V-Cache, AMD will release it to hold their current margin.

Lisa will have complete victory at hand, but wait, @adroc_thurston says Lisa will rather nickel and dime than go for full victory.

That's why you don't need a 2stack v-cache

there is loyalty in every part of every industry, it takes long repeated stuff ups to break a 30 year old pattern.

So far since Skylake Intel f upped a lot.

Are you trying to mock Alder Lake?

Are you trying to mock Alder Lake?

Nope, Alder lake was good.

Nope, Alder lake was good.

They certainly make mistakes, but there are some good ones too
Personally, I also liked Tiger Lake.

That was Very True but then RTRT happened.

Yes, so very large relatively low latency L3 cache would be nice

 

[Win2012R2]

a) cost
b) no one actually uses iGPUs.

Does not need to be iGPU - make it 600 sq mm GPU + 3D cache, that should move the needle on UE5 perf

What cost anyway? AMD puts 64 MB on 7600X3Ds now, it can't cost much - make a cracking top end GPU with it and sell it for $1k.

It's valid forever until the games neatly fit their workset into a 240M-sized slab of L3 (which is never).

According to AMD that should be enough to cache GPU stuff very effectively at 4k res, which in turn can support more compute.
