Discussion Intel current and future Lakes & Rapids thread

Yes. 2S = 2P so two socket. 2S SF 288c/288T vs 2S Bergamo 256c/512T.
Few here got too carried away br OMG 288 Core Sierra Forest. Well its like the previous leaks. Only 144 per socket and... get this: 36 Quad Clusters each with 3 MiB of L3. Same internal ring per cluster. Good luck with that.

I can't tell if this is a serious post or not.

SRF AP clearly supports 288 cores on a single package (2x 144c dies).

No, the chip recently announced at Innovation is 288c on one package so 576/576 on 2S

What do we know about Meteor Lake's efficiency by now? Specifically, how exactly Is the low power island managed and utilized, what do we think is going on with the compute tile under load wrt watts/perf, and will the chipset arch severely hurt idle power draw?

Overall not much.

LP e-cores are generally inactive in a heavy multi core workload. By design it’s not supposed to have SoC and Compute tile running their cores simultaneously.

Default behavior is to try to fit any task solely on SoC and if the workload is large enough it will migrate to compute tile.

how many memory channels a socket ? 12? even 12 is sounding pretty skinny , I will be very interested to see bulk TLS with PFS performance, I assume hyperscale is the target?

Yeah funny how even the ODMs thought that chip was axed. It's probably vaporware intended for maybe one client. Also if it's only available in a 1P configuration because reasons that would be hilarious . . . but I'll give them the benefit of the doubt that maybe they'll be able to get a 2P Sierra Forest-AP to work.

 

[AMDK11]

This dual compute tile version of SierraForest appears to be an SP LGA4710.The same GraniteRapids with 3 compute tiles also looks like SP LGA4710.Note the PCB cutouts and the similar PCB size to LGA4677.

I don’t know why you would think this. This is equivalent to Intel releasing a chip with 2x36 core Xeon cores in a single package. Not really challenging to do.

Cloud vendors will buy this in a heartbeat. Shoot, depending on price and motherboard availability, I might be encouraged to buy a couple.

Remember Cooper Lake Cascade Lake-AP?

Remember Cooper Lake Cascade Lake-AP?

If GNR/SRF-AP lack competitiveness, AMD never need to prepare Turin@500W.

Supposedly they are solving memory BW problems with MCR-DIMMs. At least for GNR, but since they share I/O and socket i think same will apply SRF-AP.
I think as always with Intel, the main worry is their mesh and memory subsystem performance in general. How much actual BW cores can use and what is the latency on the loaded system. Those are the key questions. Also MCR-DIMMs probably have some latency tradeoffs as well.

It's gonna be two schools of cloud "performance": AMD with it's massive cumulative L3 bw in socket, versus Intel, that will be working best when keeping things local to 1-4 cores in L2.

Also HotChips talked about 2 or 4 cores sharing 4MB L2, i wonder if that will result in additional products and how many cores, how much L3 they will have.

 

[DrMrLordX]

Eh they'll do it anyway. Intel still has a lot of market volume selling discounted Sapphire Rapids, which is what they did with Cascade Lake-SP for years before that. The only way a competitor can break that stranglehold on vendors in particular is to continue to excel. It's slowly eating away at Intel's marketshare, but for now all it's doing is killing Intel's margins, which is almost as good.

 

[nicalandia]

So if AP supports 2 socket...

That AP Socket is Vaporware anyways. Bergamo is compatible with SP5 MB.

You don't believe GNR-AP exists? Or do you mean to suggest SRF-AP is a different socket? Or do you mean that AMD has a 12 channel socket but Intel's version is vaporware?

Not sure if serious.

 

[nicalandia]

You don't believe GNR-AP exists?

Oh it exist as much as the 56 Core per Socket(MCM 28 cores per Module) Cooper Lake did, but did any of you got to play with them? Did any Reviewers like Phoronix, Serve The Home got to review them? Did it made any difference against AMD Epyc?

GNR-SP and SRF-SP will be the ones people will actually bench.

Cascade Lake-AP is NOT socket model.

Intel Xeon Cooper Lake To Offer Up To 56 Cores Per Socket Next Year - Phoronix

Whoever thinks the AP Models will make any difference it's beyond deluded. Emerald Rapids, Sierra Forest, Granit Rapids while positive improvements over Sapphire Rapids will not change the landscape much if any. Intel is two generations behind AMD in Server Performance.

If you think that there were no 56core Cooper Lake products because there was no demand.
That is simply mistake.

Oh I am sure Intel Made many of them for select customers. Did it make any difference? Did it stop EPYC from beating Skylake/Ice Lake CPUs and eroding market share? It made no difference. Those type of customers get that type of CPUs nearly for free anyways.

Do you think Intel was able to launch 10nm/56c product in 1H20?
Nonsense.

No, but the 56 Core Cooper Lake-AP was 14nm and socketed

It’s feels like this forum has a requirement to grossly overstate the performance lead Genoa has.

How is Genoa ahead by multiple generations when SPR outperforms Milan? How does that make sense?

Source

Genoa is a generation ahead in raw compute while at parity or behind in feature set (depending on what the client wants).

Yeah. Intel confirm that Sapphire Rapids, AMX processor, is even regaining market share.

Emerald could provide ~40% AI performance and also Granite ~3x.
Clearly, there are more good opportunities in 2024 market time frame.
