Am I... not possible right, but 7601 (Naples) vs 7452 (Rome) 32 cores CPU - is there a RADICAL difference in performance? But the price difference $500-600 vs $2000-2200 is FOUR TIMES! Not sure, there's a 4 times increase... No offence, but...

Rome is still very current, it's Zen 2.

Due to the IO die consolidating memory and pcie access and move to core chiplets and the cpu cores IPC increase of ~15% + higher core clocks and memory clocks... Rome is in a different league, and Milan is another 19% above rome...
Naples is a return to competitiveness, Rome is leadership, Milan is domination.

The 24 core 7402p is significantly faster than the 32c 7601 I would also say the 7601 price is $800 without buying from China.
So you can determine if a 24c for 1-1200 that is faster than an old 32c is worth the generational gains, or if 2k for a current gen 32c is needed for your application. Given the shortage the prices are fine... they are asking msrp for used chips but they are harder to aquire.

There are over supply of cheap epyc Naples available in large quantities (see ebay for example). Likely due to server cpu refresh from naples → rome.
I remembered in 2016 or thereabout there were surplus Xeon E5-2670 (Sandy bridge) chips been flooded in the market (I bought one like $60 back then) but the Ivy bridge cpus (next generation to sandy) were then like 2-4x the price, iirc.

All CPUs are retail versions and not vendor locked. Payment via paypal and US. Free fedex shipping.

1. 2 x 7452 $2K each
2. 1 x 7502 $2.1K
3. 1 x 7313P $900
4. tyan S8030GM2NE $400
5. tyan S8030GM2NE-2T (10G ports) $500

Merry Christmas and Happy New Year!
Are these year end clearance sales? :)
They are nice with reasonable prices. I was looking for one of these (7452) and put out a WTB out here, but no a single offer just few weeks back. But fortunately was able to get one from the other side of the globe ( with better price).

The problem with Naples isn't that its slow on average, it's that there are pathological cases where the internal architecture fails to scale as expected. Looking at @Patriot 's post for example, you would expect that a 7601 roughly matches a 7402 (the 7402 boosts higher and has a generation of architectural improvements, but 25% fewer cores), but the 7402 beats it again by roughly 25%. That's not bad, except...because the desktop parts are clocked so high, a 7402 performs like a 5950X even on workloads that scale, so you end up with a $500 CPU on a $500 motherboard which performs like a $700 desktop part with half the cores. Compounding the issue is the fact that you can't use a Naples chip as a stand-in for Rome until stock recovers, because there are virtually no platforms with simultaneous Naples and Rome support.

Naples was OK in the cloud because the hyperscalers have a different set of metrics - boost performance is not important to them because you expect your physical hosts to be fully utilized in most scenarios, and being able to scale out to tons of I/O is important because you might have a bunch of VMs hammering the disks and network at once. It was also OK for rendering work, but mostly because AMD gave you a good deal at a time when a 28C Skylake was $11K. Now that 24C Skylakes are $500 on eBay it makes a lot less sense.

It's all a little tenuous when you think about it - I'm sure part of the reason why Rome parts are so expensive is because they are "current gen", and that's still worth something to a lot of people. The 5950X is so good (especially now that 32GB UDIMMs are popular) that it's really hard to justify "small" Rome unless you are doing some crazy project with 100G ethernet and tons of passthrough.

what do you mean? there are lots of boards with simultaneous Naples and Rome support.

the issue is no platform provides simultaneous Naples/Rome/Milan support. but just Naples/Rome? lots.
