The low price of 1st gen EPYC CPUs on Ebay might be due to high demand, limited supply, or resale market trends.

Just wondering how much a second-hand EPYC costs, and found loads of these £30 EPYC listings, apparently opened but never used, shipping free from China. I assume this is a scam? Or are 1st gen CPUs really not wanted?

Currently, first-gen EPyc CPUs aren't really worth it, mainly because locating quality motherboards is a challenge and those boards can be quite costly. Plus, many of them are prototypes or engineering samples.

Check for any mention of the sample in the description or specs. Regarding the EPYC, beyond the costly motherboard and PCIe 3.0 support, there aren’t major core issues reported beyond those points.

Mostly it's because the newer components are significantly quicker than the older ones. Not quite the $30 CPUs here, but the savings will become apparent when you look at the overall cost. It wouldn't be unexpected to find a 5950x+mobo+ram set for the same price as an EPYC motherboard.

Performance suffers due to excessive power use. Zen 1 runs smoothly at reduced speeds. A 5950x outperforms a first-gen 32-core Epyc in most tasks. Even a 5800x3D usually wins: https://openbenchmarking.org/vs/Processo...X3D+8-Core Only. The best choice is for heavy PCIe needs or budget RAM at low frequencies.

It seems the first-generation EPYC is being phased out in data centers, leading to surplus supply and subsequently lower prices.

In reality, these systems perform poorly and have largely been replaced by modern datacenters. They’re not suitable for most uses because they were essentially a trial product, and only improved significantly in the third generation.

They’re weak compared to today’s standards. Their performance didn’t improve much between 2017 and 2018, and they’re just outdated given how fast CPU technology has evolved over the past six years.

The second generation performs much better and is becoming more accessible at lower costs. The first generation is no longer desirable, especially for home servers, as it's hard to find.

They're only slightly quicker than Broadwell (Xeon v4), which is much more affordable on the second-hand market. Early generation servers sometimes lack support for newer chips too. Many manufacturers didn<|pad|> to not equip their boards with sufficient flash memory to store microcode for both generations. I've been considering EPYC PowerEdge machines to swap in place of the two R730s in my lab, because it would allow me to merge both chassis without sacrificing RAM (There are thirty-two 32GB RDIMMs scattered among them, while the Intel-based R740 and R750 only offer 24 slots. I'd need a quad-socket R840 or a node server like FX2S.) The challenge is that both models come with two Xeon E5-2697 v4 processors. I can't achieve the same processing power in just two sockets on an R7415, which only supports first-gen EPYC. An R7525 would be a better fit, but it's significantly more expensive. Right now it doesn't seem worthwhile, particularly since it's essentially a hobby piece.
