Discussion Intel current and future Lakes & Rapids thread

[511]

I think I misunderstood your post (mentioning SRF).

I did think that NVidia was getting 16-channel DMR, which I think could be (one of the) reasons for cancelling 8-channel DMR - to concentrate the resources.

Nvidia is getting a custom DMR ... Like Hyperscalers get don't know what exactly they get.

The 65nm Presler seemed mostly abandoned in 2006. In fact because they were preparing for Core 2 later that year. And in that case it was the right decision. The company was stable back then though. We'll see whether cancelling -SP means further digging of the hole or Coral Rapids is indeed really good.

Coral Has SMT

Onprem dinosaurs exist and boy there are a lot of them.

Ask IBM 🤣

Revex Vs Capex. Especially for non IT businesses whose profit centres are not directly linked to their IT spend.

yeah red money vs blue money ...... your not allowed to make purple money.

2P today is like the 4P of yesterday. Looking forward to 1P DMR replace old 2P system.

1P 16ch Diamond Rapids?!?!?

You are getting 4 Sockets with DMR so a total of 64 DIMMS with 256GB Kit you are looking at 16TB RAM

@QuickyDuck was speculating about 1P systems. Of course we now know (or at least reasonably conclude) that 1P Diamond Rapids isn't happening.

1P DMR is happening cause why not

What's wrong with that?

Definitely better to have 1 x 16 memory channels than 2 x 8 channels.

 

[DrMrLordX]

Well then I'll welcome my 1P 16ch overlords. Seems like overkill for a 1P setup. Plus as has already been mentioned/implied, it will not be cheap and will be a niche within a niche, e.g. the main shipping volume of Diamond Rapids should have been 1P/2P 8ch systems that seem to have been cancelled altogether.

When you have 192+ Cores you kind of need that bandwidth and they might want to upsell a 192C/12Channel Platform instead of 8+

Having two DIMMs per channel is pointless when you have MRDIMM and LRDIMM that can deliver all 8 ranks that a single channel maxes out at in a single DIMM, so you don't lose capacity and with MRDIMM you also double bandwidth.

Nothing requires you to fill all 16 slots/channels so you can get the same as an 8 channel system if that's all you need. Yeah I suppose Intel will charge more for the 16 channel CPUs than they did for the 8 channel, but they always offer some gimped SKUs at lower prices so I could see them offering ones that are gimped to only 8 or 12 channels down the road.

 

[DAPUNISHER]

The difference between DDR4 and 5 is now several generations of performance difference on LGA 1700. Anyone that kept their DDR4 when upgrading, or chose it because DDR5 speeds and prices were unsavory at the time, is sometimes being held back with even a low end mid tier GPU.

There are (or were supposed to be) a bunch of SKUs with core counts lower than that.

I think it was 128C/96C for SP don't know the exact count

Intel Xeon 6: P-cores vs E-cores for CPU Rendering

Intel's Xeon 6 server processors come in P-core and E-core variants, so we test two similarly priced models to see which is better for a CPU rendering node.

For DMR-SP, I guess top configs were 144 cores(3*48 core tiles) changed to 96 cores(2*48) and a 64 core config?
Though not sure if there were any later changes and a possible 128 core(2*64 ?).

Hopefully RRF(Arctic Wolf E-Cores based Server line) doesn't get cancelled or delayed. If they could get their fabric and other stuff right it could be decent and much more versatile(performance and Instructions support) than SRF.

Uhh about that it has been renamed to DMR-HD

Yeah was rebranded quite sometime ago, prelim max core count still same.

Yup maybe they don't want the forest line marketing name 🤣🤣
