Epyc 4004 vs 2nd gen Epyc

Hardware Hub CPU
1

Currently my nas is running on an amd 2700x salvaged out of my previous pc. I’ve been thinking about upgrading hardware. Has not been a problem free system.

Question is I have been thinking for awhile about going to something like an Epyc 7302. The cost of 2nd gen epyc is such that for sub $700 you can get a , chip, mb, and lots of ecc ram.

Does anyone see a compelling reason to go 4004 instead of 2nd gen epyc? Cost on 4004 would be much higher.

My use case is pretty lite. Storage, streaming, and a few containers.

Thanks

The main reason to go for Ryzen/EPYC on AM5 is single core performance. Possibly, access to PCIe Gen5.

The main reason to go Epyc is either you need >16 cores or you need >24 PCIe lanes.

or lower power consumption. EPYC Rome and EPYC Siena (8004 series) are really good on low power.

And memory bandwidth and channels are another benefit as well as a lot of good server boards to choose from. AM4/5 has some, but mostly gamer boards. If I want IPMI and all the goodies, EPYC has options…

edit: oh and there are a lot of use cases for 8-16 core EPYC servers. And these small CPUs are dirt cheap…EPYC Siena 8 core is about the same as Ryzen, 16 core is like 700€. I can get a good EPYC Siena board for less than I payed for my X570D4U-2L2T. EPYC isn’t expensive

DDR5 for Siena caught my wallet on fire just looking at it tho.

2nd gen EPYC is a good mix of performance and cost efficiency (and power efficiency) if you pay attention to the models you are getting.

Forgot about that one…150 for each 32G stick. Same expensive stuff as my ECC DDR4 UDIMMs a couple of years ago. Rome with DDR4 RDIMMs is dirt cheap in comparison

You don’t even need epyc 4004. Ryzen 7600 is good enough. As your use case, you don’t even need many pcie lines.

Yeah, on the surface of it 15% extra for a 4244P’s kind of an expensive way of lowering a 7600X to 65 W TDP. I’d hope 4244Ps are at least a better bin for that than 7600Xes but haven’t seen anything to indicate AMD’s doing anything in that regard. A 9600X’d make more of a difference and isn’t much more than a 4244P anyway.
