Are you just writing nonsense or do you state with certainty, that AMD will present us a 24% IPC increase?
Why cut down the structures ? .. zen 4 was well designed for its size 🤔View attachment 101536
The bean counters are counting the mm2 at AMD.
Then there are lamentations and the weeping and gnashing of teeth for the non believers of the bigly IPC gainz
If Zen5 X3D will be released already in September, are any of you intending to buy the vanilla variant in July anyway and if so why?

Probably a consequence of running the same design on client and server (full rate AVX-512). Good for Turin, but not that relevant for GNR and STX.Counting the mm2 but double vector bandwidth and a full rate AVX-512?
Doesn't really add up, dis. Seems like a pretty easy cut if they wanted to save area at all costs.
They added some places and took away in other. But that's not unusual.

I’m guessing the numbers provided to OEMs were the 10-15% range we’ve seen before.
For the Mobile versions, looks like a possibility that they cut L3 cache and some PRF as well, possibly to cut power and cost.Probably a consequence of running the same design on client and server (full rate AVX-512). Good for Turin, but not that relevant for GNR and STX.
Yeah, I know of him he's credible. He's done a lot of good work in the past.
Cutting the PRF (or any other core-private resource for that matter) would be a first for any Zen IIRC?For the Mobile versions, looks like a possibility that they cut L3 cache and some PRF as well, possibly to cut power and cost.

Zen 5 was planned before the latest AI meme. And if they were all about wasting area for AI they'd have added something like AMX.AI AI AI
Yes, usually they design a core and that's what you get across the entire product stack. I think they only customised the FPU for PS5, but that's semi-custom business.And would be extremely out of character for how AMD has generally worked.
I expect Zen 5 to largely just be Zen 5, not "here's Zen 5 but with fewer physical registers here, a smaller scheduler there, an extra cyc of latency on the FMA..."

We already know Strix L3 (16MB for Zen5 CCX, 8MB for Zen5c CCX).True. But there was enough time to gimp the L3, right?
It makes sense. TSMC isn't getting any cheaper so penny pinching on mm2 is only going to get worse. Strix Point laptops are already expensive enough as it is.
Gimp how?True. But there was enough time to gimp the L3, right?
We already have the L3 AIDA benchmark data. There's no decrease in bandwidth or latency compared to Z4.True. But there was enough time to gimp the L3, right?

What if the actual uplift is only +10%, that should satisfy both viewsYep. Thing is, parameterization of stuff like that often costs more in dev/validation than you save in an incrementally smaller core variant. AMD has been wise to mostly avoid it thus far.
I think anyone believing that Strix Zen 5 will somehow be a materially worse microarchitecture than desktop Zen 5 is going to be disappointed.
STX Z5/Z5C=FP 256Yes, usually they design a core and that's what you get across the entire product stack. I think they only customised the FPU for PS5, but that's semi-custom business.
