Intel cancels part of its next-gen Diamond Rapids Xeon lineup, report claims — Xeon 7 will drop models with 8 memory DIMMs to focus only on 16-channel CPUs for extra memory throughput
Up to 1.6 TB/s mixed with 2nd-gen MRDIMM.
Things are heating up again on the server side of CPUs, with both Intel and AMD gunning for the crown. Just yesterday, we covered Granite Rapids-WS, the next launch in the Xeon series, and today we have confirmation from Intel on how Diamond Rapids will shape up. Xeon 7 was originally set to include two lineups: one with 8-channel memory and one with 16-channel, but the former has now been cancelled. Diamond Rapids will therefore be exclusively 16-channel.
Speaking to ServeTheHome, an Intel spokesperson clarified: "We have removed Diamond Rapids 8CH from our roadmap. We're simplifying the Diamond Rapids platform with a focus on 16-channel processors and extending its benefits down the stack to support a range of unique customers and their use cases."
The existing Granite Rapids server chips, along with AMD's competing EPYC Turin lineup, top out at 12-channel memory, which will be upgraded to 16-channel with next-gen products from both companies. Previously, when we first reported on Diamond Rapids earlier this year, both the 8CH and 16CH options were said to be on the table. Now, the pivot to only 16-channel memory could result in improved performance, with approximately 1.6 TB/s of memory bandwidth — up from ~844 GB/s.
Those numbers are achieved not just through more DDR5 channels, but also because Diamond Rapids is tipped to ship with 2nd-generation MRDIMM (Multiplexer Rank Dual Inline Memory Modules) that will boost the maximum memory speed from 8,800 MT/s on current-gen Xeon 6 to a whopping 12,800 MT/s. Xeon 7 will also use the new LGA9324 socket, and top out at 192 cores distributed across 4x 48-core compute tiles. Keep in mind that these cores are still not hyper-threaded; that deficiency will be addressed with Coral Rapids afterward.
In the meantime, Diamond Rapids will go up against AMD's EPYC Venice lineup next year, which is rumored to feature up to 256 cores built on the 2nm Zen 6 microarchitecture, so Intel may lose core-count parity, at least on the server side. The now-cancelled 8CH Diamond Rapids would've succeeded existing 8CH Xeon 6 6700P/6500P SKUs that are designed to be cheaper, but cost-effectiveness often goes out the window when it comes to scaling data centers, especially these days.

thestryker This is a seemingly odd move given the volume the lower SKUs sell. That means no intermediate socket for DMR at all. I don't see how ceding the volume market makes for a good business decision as companies buying in this area aren't suddenly going to be able to double or triple CPU budgets. This also limits multi-socket capability which has been Intel's biggest platform advantage.Reply
About the only thing that makes sense to me is that perhaps Intel is using Coyote Cove as the basis for a new Xeon which will be coming sooner rather than later. The whole Xeon line has been a mess since AMD brought 64 cores to the table and has maintained core count superiority until GNR/Turin (Zen 5 being superior to Redwood Cove). Making that market wait even longer for a true architecture improvement seems like bad business. -

From what I have heard (unconfirmed obvs), Intel is instead pulling the next generation up by a couple quarters or so.thestryker said:This is a seemingly odd move given the volume the lower SKUs sell.

I assume you're talking about 16-channel Diamond Rapids (and also AMD Venice), rather than the cancellation?ashinms said:It's been a long time since I was exited about hardware. This is just what the doctor ordered.
I think the past decade has been pretty fascinating, with the rise of chiplets, massive core-scaling, new I/O interconnects, HBM & other memory tech, wider vector & matrix instructions, E/C-core server CPUs, and hybrid CPU/GPU processors from both AMD and Nvidia. Also, ARM coming onto the scene. It's too bad I only get to read about most of that stuff. -

Yes. The 16 channel server parts. I have to say that the last decade was hell on earth for me. I remember something about AMD announcing this new Zen thing and then waking up missing teeth and divorced. I just want Bulldozer being garbage to be the worst thing in my life again.bit_user said:I assume you're talking about 16-channel Diamond Rapids (and also AMD Venice), rather than the cancellation?

I'm sorry. I just re-activated this account after well over a decade of inactivity and I'm feeling nostalgic.bit_user said:I assume you're talking about 16-channel Diamond Rapids (and also AMD Venice), rather than the cancellation?

Sorry to hear about your misfortunes, but at least this small corner of the internet is somewhere you can simply geek out about computers.ashinms said:I'm sorry. I just re-activated this account after well over a decade of inactivity and I'm feeling nostalgic.
