The All-Efficient Core CPU: AMD's 64 Core Siena

The talk of new 'efficient' cores from AMD and Intel has me wondering - who did the server CPU first will all efficient cores? The answer, is AMD. First Bergamo, but now Siena - the prime candidate for any upcoming workstation platform! 64 cores, single socket, PCIe 5.0, six DDR5 channels. If you are happy with 3.1 GHz, then Siena is for you!

(and no, Xeon Phi doesn't count)

Here is to hoping for a supported "non-pro" Threadripper based off this...

This upload cadence is more than impressive too.

I know an Intel VP whose department sells edge nodes for telecommunications. The hardware at the edge node is getting so powerful now, they are selling use cases for telcos to basically sell that excess compute power and then sell a more powerful processor as it can be used to generate revenue for the telco. And with the power of the cloud and dispatchable resources it doesn't really matter where the hardware sits or if you lose a small cluster from a cut fiber, power outage or whatever.

You might spend more hardware up front, sell those extra resources and don't need to worry about traditional things that come with a full phat datacenter.

This is super exciting, Ive been working with quite a few EPYC platforms on the edge lately and ive been super impressed. These new chips will only make the next gen of those even better, though w/ how vendors like to stretch things out its probably gonna be a while.

[roamingeek]

FYI. Dell is now quoting a new C6615 Siena based system, but only if you call, not available on the website. It's a 2U4N system in the 6600 chassis.

these also make sense for SMB that would like at least 3 hosts for redundancy.
3 * servers with 9000series epyc is quite expensive and many smaller companies dont need more than a few dozen cores.

[HexerPsy]

I would like the see one of those street side deployments from up close. Never thought about such edge cases and would love to learn more.

[ingoos]

Just goes to show: vigorous competition quickly spurs rapid innovations which, ultimately, benefits everyone.

[tjcarr]

Thanks for explaing Ian, appreciate you helping to clarify the specs on these confusing chips.

I'm betting the next gen TR platform is going to be based on the SP6 socket. Very HEDT like power envelopes and core counts already.

Edit: I apparently missed the leak from August, which indicates socket sp6 for TR 7000

Ty Ian!!! Excellent breakdown of this new Telecom solution! Looking forward to your upcoming tests. Although Cinebench R24 and Crysis sounds fun, I'd like to see V-ray CPU, Chromium Compilation, DaVinci Resolve, After Effects, Unreal Engine compilation, AutoCAD 3d graphics, and CPU performance, although that's not really this new product is about. Might be time for a telecommunication /efficiency benchmark....

The cool thing about Zen 4c is that, unlike Intel or ARM little cores, it is full Zen 4, but with the logic blocks more tightly packed. The benefit is cheaper manufacturing and lower thermals. They didn't do this from the start because it takes longer to design and peak clock speeds are lower. Desktop users probably still want the original Zen 4 for peak clock speeds. Everyone else probably wants Zen 4c for lower power use and cost.

Would you be able to EQ the audio for future uploads? There is a lot of rumble that shouldn't be present in voice, a low cut filter or other audio processing would make it much easier to listen to your videos. Some sound deadning for your room could help too, since there is a lot of room reverb, but I appreciate that is a bigger change to make. That said, hanging up a duvet on some flat wall sections may help for not huge amounts of money?

I'd actually love one of those 8 core CPU's in a system for home use and I'm pretty sure the 8/16 core CPU's would be a viable option for some of my clients for on premises servers. I've been pretty impressed with Epyc since I started playing around with the 7xx2 stuff (ended up grabbing one used for my home proxmox server) and hope TR7000 is generally available this time around now that Intel is making a presence back into the HEDT market.

Siena might also be the pioneer of a line of CPU models that has Xilinx PGA goodness inside, all on SP6.

Tests: ZFS caching (In-memory) performance and latency for database and web applications in single or a 3 node cluster.

My first visit on this channel. Great content and I love the logo 🙂

[chromerims]

Thank you, Dr. 👍
AMD Siena's pcie lanes and ram channels are very appealing.
Kindest regards, neighbours and friends.

[administrator]

Care to explain what Xeon Phi processors were if not all efficiency cores?

[cracklingice]

I was hoping that this SP6 could be re-used to offer up to 32c (zen4/zen4-3d) Threadripper consumer but it doesn't look like that would be possible. It looks like they'd need to at least modify the substrate to chiplet connections. I'd also expect to see a drop to quad channel and ~48 PCIE lanes.
