5Ghz+ Firestorm has to wait another year.
Physics be damned.
But why would I?And when Adroc tries to cook up bogus defenses for his big miss today.
Geekerwan found SPEC IPC increase to be around 7-8% for M4.I think you're over valuing the ARM and Apple IPC improvements. M4 was like 5% improvement and has been <= 5% for multiple generations now. The latest ARM big core seems to be < 10% though that's still TBD with proper testing. Apple (and ARM to a degree) have mostly been increasing performance through clock gains. Apple is still IPC king because of the lead they had starting several years ago, but IPC increases have not been good as of late.
Is it iso XCode version or notGeekerwan found SPEC IPC increase to be around 7-8% for M4.
People shit on Apple but it’s hard to
My computations based on Geekerwan data from his first video shows 4.6% IPC increase for M4 vs A17 Pro on SPECint.Geekerwan found SPEC IPC increase to be around 7-8% for M4.
?After the Zen 4 stumble
It feels like good old AMD is back. After the Zen 4 stumble and RDNA3 fail we got a classic "grounds up" design. Zen 3 was a pleasant oddity.
It's 3% less in IPC from Zen 3. I don't consider that a big miss personally, especially since IPC gets harder to extract.MLID got legit AMD slides. Yet, the "30+%" leakerz dismissed them. I mean those having just vague OEM projections at best. Just kek
Btw Cheese was also right - https://chipsandcheese.com/2023/10/08/zen-5s-leaked-slides/

Engineers gets more exited about architecture than actual performance.Yeah, kind of wonder what Mike Clark was on about when talking Zen5, idk, two years+ ago. It’s almost like someone made him take a big cut to the Zen4- Zen5 xtor budget increase.
Tje most telling part of this slide is the missed schedule. We'd supposed to have Zen 6 by now.Not an MLID slide. I was the one that convinced Adored not to do a video on it, because the IPC number was lower than expected. My fault for accidentally giving MLID more credibility.

That's not how you read the slide.Tje most telling part of this slide is the missed schedule. We'd supposed to have Zen 6 by now.
I think they mean Zen 5 still hasn't reached Firestorm IPC.
Well yeah, heavy pro workflows in Geekbench inside fridge is something AMD won't touch Apple in. I doubt they can even do it. Unless it's some slaughterhouse refrigerator with power mains in...And the 9950X will probably be behind a 10W iPad in day-to-day tasks because it didn't achieve that nor did it push clock rates higher. Although I guess it is a fair bit cheaper...
If it is below targets, it's likely the good old chicken bits, new bottlenecks discovered too late and going to get fixed later, generally stuff panning out below expectations, or not as above "expectations" as actually expected (hoped for).The post mortem will be interesting, is the frontend not as bigly as we thought? PRFi or rob sizes smaller then expected? Not a large enough jump in prefetch / predict? If rob >512 and decode a complete rework then I will say zen5 is bulldozer tier execution, they just are in a much better place before hand and made far better architectural choices.
its so pretty.I saw this get posted on Xitter by HighYield... STX, is that you?

isn't that going to Zen6 32Cores?Now is it okay to ask for more than 16 Cores in desktop?
No.isn't that going to Zen6 32Cores?
