You are paying for support, more validation, ECC, etc... by going with the Epyc. Don't forget that 1st Gen Epyc embedded went from 4c/4t > 16c/32t. There is a market for 8c/16t server class embedded CPUs. These things need the assurance that the CPU is designed to run 24/7 for years on end. A desktop CPU is not designed for that type of usage.Reply
Please AMD, give us cheap and efficient. Like in the Microserver gen10. All the recent embedded parts are so incredibly expensive. 4 cores 15 Watts is enough. But under 150 euro including a dual nic ITX board.Reply
Gen8 (Ivy Bridge) was even better in some respects, mine's still going strong with an i5-3470T - only two cores, but four threads at least. Got it for about 160 GBP - someone bought too many.Reply
Genoa sample volume available in the channel since 1.7.23 at 6.5% of Milan. On Sapphire Rapids applied computer science project leaving a commercial market volume void, BIG opportunity for AMD to drive 20 M units of Epyc into the enterprise market between Milan and genoa through the end of the year.

I saw semiaccurate article about 2 DPC ram issues for Genoa? Is that resolved here. Based on Charile it will take until H2 of this year and that is impacting ramp at CSP. its not just Charlie. Patrick Moorehead also mentioned it and it came up in recent AMD financial conference. Reply
:( 200W is the *lowest*? Oof. I love Epyc Embedded and use it extensively for firewalls and such, but the Zen 1 foundation has been getting long in the tooth. I've been super excited to see the next gen. But this doesn't seem like a successor at all, rather it's just a mildly modified version of their full fat server chips. The 3001 series were 35 to 100W TDPs. The lowest power ones could work full passive cooling, and even the top end part with quite minimal active.
Going from 35W to 200W and 100W to 360W is, ouch. I guess maybe some OEMs might restrict it from the box and build around the restricted TDP? Might at least get below 100W that way. But while more power top end is all well and good I'm genuinely pretty bummed they couldn't at least do a 50-65W offering. Almost 400W definitely isn't what I've ever thought of as "embedded" territory.Reply
I have the impression Anandtech is run on a skeleton crew these days. All the knowledgable people who used to do the in depth cpu reviews are long gone, and it doesn't seem Anandtech has hired replacements for them. Reply
Basically I think Gavin is meant to be "the new Ian". Which is a role you have to grow into, as Ian did from news and reviews. Perhaps David Kanter of Real World Tech could do a few guest posts in the interim on the more esoteric aspects of CPUs? https://www.realworldtech.com/cpu/Reply

Too bad there isn't a 16c/32t single socket version. Replybrucethemoose - Wednesday, March 15, 2023 - link
The desktop Ryzen die makes more sense because its way more power efficient.If you *really* need EPYC's IO in 16C, then shelling out for the 2P chip is probably a drop in the bucket anyway. Reply

Agreed. To be clear I meant an embedded variant of the desktop silicon, not the actual Ryzen product line.What I am saying is the EPYC IO die is now too big and power hungry for low core count embedded CPUs. Reply

Especially with how well Zen4 scales down. It's nearly 80% performance when locked at 40% of its TDP. ReplyGreenReaper - Friday, March 24, 2023 - link

240W for 32C. 7.5W per core... I know I/O is eating a lot, but that still doesn't seem like a perf/W sweetspot.The 96C part is 3.3W per core at 320W, which is more like it. Reply

Anandtech used to review chips like this. For example, Anandtech reviewed Ampere Altera 2x 80 cores.Now Anandtech reviews PSUs and SSDs. Reply

Hard to find such people sometimes. I mean, first of all they got bought out by Purch:https://www.anandtech.com/show/8790/anandtech-acqu...
then they got sold on to Future:

then Ian left, which IIRC is where the CPU reviews came from:
