The fine print on the slides could lead you to believe that they are deliberately underestimating the IPC/performance of Zen 4. Doesn't seem like a good strategy to me, but we'll find out the truth eventually the right way: by reading third-party reviews instead of leaks and marketing claims.
As to why they might be downplaying performance? They could be trying to dampen expectations give some of the wild rumors claiming 40% IPC increases both with and without 3D v-cache included and significant clock speed increases on top of the IPC gains. If these rumors went unchecked, then whatever AMD released would have been met with disappointment (even if they blew Intel out of the water across the board). From AMD's perspective, it's always better to under-promise on early performance previews and over-deliver on performance at release. They did the exact same thing with the original Zen chip.
I also do not think they are deliberately underestimating performance. I think they are just being very conservative in their estimates and careful with their wording.

Originally posted by jaxa View PostThat sounds overly optimistic for Raptor Lake's single-threaded gains. It will probably have a similar bump to this (IPC + clocks = 10-15%), and it will be adding another 8 small cores, but only in the Core i9. But as it stands, that's more than enough to defeat Zen 4. We'll see if that changes in a few months.

But yeah, only time will tell.

Originally posted by Anux View PostI'm confident if they claim 15 % more single thread performance it will be right there, maybe 1 or 2 % off for independent reviews. Since the start of Zen AMD has been pretty honest with their performance claims. If Intel made that claim I would instantly bet its around 7 to 5 % in reality. Intels "benchmarks" must be a meme by this point.
But yeah, only time will tell.

That said, I've not seen a major uplift in speed for the code I actually care about on the 6300 Xeons vs. the 6200 Xeons... and AMD will continue to be popular in the datacentre if their core count keeps going up. We'll see what Sapphire Rapids brings to the table.

Good to see as the competition benefits everyone. I also like the idea of on-board graphics too rather than have special 'g' chips for the purpose. My server boxes for example run headless and normally don't need a monitor, but there are times when you need one to update bios settings and such. That's where the GPU on the CPU come in handy.
That said, I don't see me jumping on the AM5 system right away if not for a long time -- unless current motherboard/cpu breaks of course. I have so much performance just 'sitting there' with my Ryzen 5000 series boxes (5900X and 5600X), I just don't see any need for upgrading. I can't help wonder if there are others out there like me that will just stick with the AM4 platform for the foreseeable future. All my systems run Linux of course. VMs run very well... Just can't see/justify upgrading.Last edited by rclark; 23 May 2022, 09:05 PM.
