What app are they using in this screenshot? https://www.servethehome.com/amd-epyc-7c13-is-a-surprisingly...
Looks very neat!
NOT shipped by newegg but very interesting https://www.newegg.com/tyan-s8030gm4ne-2t-supports-amd-epyc-...
Seems like a good value per dollar for a monero mining rig approx 4 x the performance of a 5950x on monerobenchmark site. Given that the epyc has about 4 times the cache (256MB vs 64MB) this makes sense in the monero world. I'd assume real world performance side by side compairison the epyc would get up past 4x than a real world 5950x which requires a lot of tweaking to get anywhere close the monerobenchmark numbers.. I'd expect the epyc runs better out of the box
I recently picked up a 64-core AMD EPYC Genoa QS (eng sample) on ebay for $1600, and have been very pleased with the performance.
I bought 2 new retail boxed WOF 7402's in 2020 for $734.54 USD each. 96 threads and 256 MiB L3 total, decent single- and multi-core performance. So I can't currently justify upgrading to (used) 7742/7702/7H12, much less any form of Milan or later chips. I also looked into upgrading to 1, 2, or 4 TiB of RAM, but the costs still remain absurd.
I guess I'll take my type-1 virtualized, 2 Romes, 0.5 TiB DDR4-3200 RDRAM, 32 TiB NVMe SSDs, and ~150 TiB net RAID10 of Ultrastar HDD until the wheels fall off, because it's more than I'll need for almost any purpose. Whenever I need more temporarily, I rent it rather than sink personal $ into excess metal.
PS: During the pandemicfest, I shoehorned the H11DSi-NT into a Core V71 TGE with a bit of Dremeling and tapping holes. The case is rammed with enormous Noctua fans, an AX1600i PSU, and USB distribution for a TRNG and an HSM.
Still rocking my EPYC 7282 in my home server, which really sits in a sweet spots: 16 Cores, about $700, 120W TDP (because of the reduced memory bandwidth).
Looks like the 7303 fills that same niche in the Milan generation (and should be compatible with any ROME mainboard, possibly after a BIOS update), or if you're building a new system you can get the 32-Core Siena 8324PN for about 130W TDP.
(While it may be silly to look at TDP for a server CPU, it does matter for home servers if you want a regular PC Chassis and not a 1U/2U case with a 12W Delta cooling fan that is audible three cities over. In fact, you can get the 8-Core 80W 8324PN and still get all those nice PCIe lanes to connect NVMe SSDs to, and of course ECC RAM that doesn't require hunting down a specific motherboard and hoping for the best.)
For home use I'd rather get 7945hx only issue is 96G ram.
This is some fell-off-a-truck stuff. Aren't the weird part numbers with infix letters custom made for large customers (Amazon, Google, et al.)?
Last Generation
Am I mistaken but isn't this AMD's last generation server proc?
The current generation is 7xx4 / 9xx4.
Which should be surprising it's cheaper.
have a 7B13 gathering dust if anyone is in the market in the bay
This naming is confusing. Is 7C13 > 7950X? Why can't companies stick to simple conventions of "higher numbers are better" ...
Even NVIDIA ... A800 > A100 > A10 but A6000 < A100
It's good but I have a feeling anything you find on aftermarket will be used and abused. These chips are designed to handle high thermal load, but if it's been in a DC or server room, it may impact its longevity.
The article states the 7C13, priced in the $1900-2000 range, seems to be a low-cost version of the more common retail 7713P, priced officially around $5000 about 2-3 years ago. But the thing is the 7713P itself is such an old processor that it can be found for even cheaper: from $1300 to $2000 right now.

Of course these are sellers who sell low volumes and who are not well-known, but that's just because all these processors, 7C13 or 7713P, are at their end-of-life so none of the big retailers have them in stock.
