One of AMD's most powerful CPUs gets a 60% price cut — 192-core EPYC 9965 CPU costs less than $6000 new and I can't explain why it's so cheap

AMD Zen 5-based EPYC 9965 is on sale on eBay for just under $6,000
With 192 cores and 384 threads in tow, AMD’s offering can handle as much as 6TB of RAM per processor for AI-centric workloads
The CPU not only offers the highest core count in all x86 CPUs to date, but also holds its own against the competition

When AMD unveiled its new EPYC CPUs in June 2024, one particular chip caught everyone’s eye, given how outrageously powerful it was compared to the competition.

The AMD EPYC 9965 CPU was also the company’s most ambitious server-grade offering to date, and one that has held its own against the competition with relative ease thanks to its yet-unmatched 192-core, 384-thread x86 configuration.

At a suggested MSRP of $14,813 (now $11,988) at launch, it is also one of AMD’s most expensive products across the board, with only a few of its server-grade GPUs pushing noticeably higher.

Why the eBay listings are somewhat hard to digest

Despite being unveiled over two years ago, the EPYC 9965 CPU remains largely unchallenged by the competition, thrashing most benchmarks with relative ease. It remains the flagship server chip for AMD-based systems worldwide, with Team Red shipping it globally, including China.

The chip itself is a genuine monster. The EPYC 9965 packs 192 Zen 5c cores and 384 threads onto a single SP5 package, with a 2.25 GHz base, a 3.35 GHz all-core, and a 3.7 GHz maximum boost, 384 MB of L3 cache, twelve channels of DDR5, 128 lanes of PCIe 5.0, and a 500 W default TDP, AMD’s highest yet. It is the densest part in AMD’s 9005 stack, built for cloud providers aiming to cram the maximum number of virtual machines into a rack.

All in all, it is designed primarily to serve hyperscalers and cloud providers, with a focus on low-power, efficient cores that dominate such setups.

Even at its reduced reference price of just under $12,000, eBay listings selling the same CPU for just under $6,000 seem inexplicable, offering a sub-50% discount over current advertised prices and over 60% off its original launch price.

This is even lower than the last time we tracked this CPU in 2025, but there might be an explanation of sorts for what would otherwise be seen as an anomaly. Most server-grade CPUs trade at prices below MSRP, with OEM and negotiated discounts that quickly add up to significant savings for large-scale deployments.

The other explanation that often applies to older server-grade CPUs that often get cycled out or decommissioned by data centers does not apply here, however; the EPYC 9965 does not have a successor yet, and it is hard to imagine a currently available CPU replacing AMD’s most capable chip yet in a data center just yet

Other reasons prices are low could include excessive inventory, canceled orders, or simply someone liquidating hardware in an industry that is increasingly GPU- and memory-focused to meet its AI needs.

Most industry players prefer a direct OEM solution, especially given AMD’s support for PSB-locking (secure boot) on their CPUs for certain vendors, which makes them unwilling to purchase from 3rd-party sellers. This also raises the risk profile for buyers, who could unwittingly end up purchasing a vendor-locked CPU, making for a rather annoying testing and return process.

With a shift in spending towards GPUs and memory becoming prohibitively expensive, hardly helping matters, while enterprise consumers are still buying up the EPYC 9965, prices might reflect a market reality: they are unlikely to be scouring eBay for their next 192-core monster CPU purchase, even assuming they have a compatible motherboard and memory modules to match.
