Discussion Intel current and future Lakes & Rapids thread

If they are buying the ARM server parts, then they are buying E core Xeons. Which is the reason for them existing in the first place.

I don't think there's much buying of ARM server parts beyond the self made chips like Gravitron.

For x86 compatibility, I imagine the cloud vendors would choose Epyc dense over any E core Xeon. That's probally not changing.

5th Gen Intel Xeon Processors Emerald Rapids Resets Servers by Intel

We delve into the 5th Gen Intel Xeon Scalable Emerald Rapids generation and talk both the performance and platform gains around the new chips

Considering that EMR holds up his own on per core perf against Genoa, and simply gets outclassed due having 33% less cores

Emerald Rapids consumes too much power to achieve this feat. And at least in 2P configuration, the top-end Emerald Rapids struggles against the "lowly" EPYC 9554:

Intel Xeon Platinum 8592+ "Emerald Rapids" Linux Benchmarks Review - Phoronix

(yes it's Phoronix, but their test suite for server CPUs is much better than desktop)

Yes it was better than Sapphire Rapids, but eh too little too late.

I'd say GNR, which will have core count parity with Turin and upgraded performance per core, is gonna more than hold its own against Turin, it'll even beat it in a fair amount of use cases.

Again, it's on them to prove such claims. Granite Rapids being "Redwood Cove+" does not inspire much confidence.

I think that it may be due to the lack of any avx-512. Server use that a lot.

For some workloads... Other workloads don''t use it at all, and that's where E core Xeons make the most sense.

Agreed. The last independent player here seems to be Ampere (used by Oracle).

x86 compatibility is becoming less important every year for cloud vendors as many SW has been ported to Arm and Arm-based server CPU have become competitive. Though of course that doesn't mean x86 is going to disappear any time soon.

As far as AVX-512 goes, in the server market I don't think it has enough uses outside of HPC to be a significant differentiator. OTOH for large databases uses hardware accelerators might play a role, though I'm not sure it's a big part of the market (but admittedly one with huge margins).

Keeping ARM out of the server space is reason enough to keep going with Dense and E core parts.

By the way:

That's bonkers performance for Sierra Forest. It's a perfect Cloud and VM chip, which is where the real ARM server threat is.

Yea, Clearwater Forest on Int is basically Zen 5C on 18A with Foveros Direct.

Without HT which can be plus point for some markets
