Intel Xeon E5-2680V4 12-core FCLGA2011-3

The Intel Xeon E5-2680 V4 is a 12-core, 28-thread server chip that's dirt cheap on the used market, with EUR listings ranging from 146 to 342. Multi-threaded performance is solid at 7,363 PassMark, but single-thread is only average. It supports up to 1.54TB of DDR4 ECC memory and dual-socket configs, making it a killer homelab or virtualization CPU. Skip it for gaming or daily desktop use.

The multi-thread score of 7,363 in PassMark puts this chip at the 71st percentile overall, which sounds modest until you remember what you're paying. In our database, that's a solid showing for a 12-core part from 2016. Real-world translation: you can run a handful of VMs, transcode media, or crunch through batch jobs without the system feeling like it's drowning. The 35MB of L3 cache helps keep those 28 threads fed, and the 9.6 GT/s QPI links mean dual-socket boards can scale up to 24 cores and 56 threads if you're feeling ambitious.

The single-thread score of 259 is the weak spot. That's 51st percentile, dead average, and it's the number that matters for anything latency-sensitive. A modern Ryzen 9 7900X will absolutely embarrass this chip in single-threaded tasks, and even a budget desktop CPU from the last few years will feel snappier in day-to-day use. The 2.4GHz base clock doesn't help, though the 3.3GHz boost takes some of the sting out. For server workloads that parallelize well, you won't notice. For gaming or single-threaded productivity, you will.

The obvious modern comparison is the AMD Ryzen 9 7900X. That chip has 12 cores and 24 threads, but it runs circles around the E5-2680 V4 in single-threaded performance and efficiency. The Ryzen is the better choice for a new build if you can afford it. But it costs several times more, and it doesn't support ECC memory on most boards. The Xeon's advantage is the platform: cheap ECC RAM, dual-socket support, and a price that leaves room in your budget for storage and networking.

Against other used Xeons, like the Dell E5-2637 V2 or the PC Server and Parts E5-2697 v2-cr, the E5-2680 V4 holds up well. The E5-2637 V2 is a quad-core part, so it's not even in the same conversation for multi-threaded work. The E5-2697 v2 is a 12-core Ivy Bridge chip with lower IPC and higher power draw. The V4's 14nm process and DDR4 support make it the better pick among these older options. The be quiet! Ryzen 3 Dark Rock Pro 5 and MSI MAG X870E Tomahawk WiFi are odd inclusions in the competitor list, they're a cooler and a motherboard, not CPUs. We'll chalk that up to category matching weirdness and move on.

Here's where things get interesting. The price spread on this chip is wild. In EUR, listings range from 146 to 342 across German, Spanish, French, and Italian sellers. That's a 196 EUR gap for what should be the same silicon. The best deal in our data is the 146 EUR listing, and at that price this chip is an absolute steal for a homelab build. The GBP listing at 90 is even more aggressive, though availability seems limited to a single UK seller. The USD listing at 210 and the CAD listing at 283 are less compelling, but still reasonable for what you're getting.

Compared to buying a new 12-core desktop chip, you're saving hundreds. The catch is that you're buying into an older platform. LGA 2011-v3 motherboards are cheap but aging, and you'll need to source DDR4 ECC memory, which is plentiful but not free. Factor in a decent cooler since there's no heatsink in the box. Still, for a multi-threaded server or workstation, the total cost of entry is hard to beat. Just shop around, because that 196 EUR spread means some sellers are charging way more than they should.

The Intel Xeon E5-2680 V4 is a 14nm server chip from the Broadwell-EP generation, and it's one of those parts that makes you realize how much compute you can get for very little money on the used market. This is a 12-core, 28-thread processor with a 2.4GHz base clock and a 3.3GHz boost, sitting on the LGA 2011-v3 socket. It's not new, it's not flashy, and it won't win any gaming benchmarks. But for homelab tinkerers, budget workstation builders, and anyone running virtual machines or software-defined infrastructure, this thing is quietly interesting.

Who is this for? Mostly people who know exactly what they're getting into. You're buying a retired enterprise workhorse, often sold as a certified refurbished unit with a 90-day warranty. The listing we're looking at is a Japanese-market retail box, and the description leans hard into cloud architecture and data center workloads. That's the intended audience. If you're building a NAS, a Proxmox box, a render node, or a cheap multi-threaded server, this chip slots into a very specific value niche.

What makes it interesting is the platform. LGA 2011-v3 boards are cheap now, DDR4 ECC memory is plentiful, and the E5-2680 V4 supports up to 1.54TB of RAM across four channels. That's a lot of headroom for a processor that costs less than a mid-range gaming CPU. The trade-off is single-thread performance, which is about average by today's standards, and a 120W TDP that means you'll want decent cooling. But if your workload scales across cores, this chip punches way above its price tag.

Gamers should skip this without a second thought. The single-thread score of 259 and the gaming rating of 31/100 mean you'd be better off with almost any modern desktop CPU, even a budget one. If you're building a machine for everyday productivity, web browsing, or office work, this chip is also the wrong tool. The low base clock and average single-thread performance will make the system feel sluggish compared to a modern mid-range processor.

If you need a CPU for a new build with a warranty and modern features like PCIe 4.0 or 5.0, this isn't it. The platform is aging, and the 90-day refurb warranty is short. For those use cases, look at a Ryzen 5 or Core i5 from the last couple of generations. You'll get better single-thread performance, lower power draw, and a proper warranty for not much more money.

If you're building a homelab, a virtualization box, or a budget render server, the E5-2680 V4 is a fantastic value. The 12 cores and 28 threads handle parallel workloads with ease, and the memory support is genuinely impressive for the price. Pair it with a cheap LGA 2011-v3 board, load up on DDR4 ECC, and you've got a serious little server for less than the cost of a mid-range gaming CPU. The 90-day warranty on this refurbished unit is short, but at these prices, the risk is low.

If you're building a gaming rig or a daily driver desktop, look elsewhere. The single-thread performance is average at best, and the gaming score of 31/100 tells you everything you need to know. A modern Ryzen or Core i5 will feel dramatically faster in everyday use. This chip is for people who need cores and memory bandwidth, not snappy single-threaded responsiveness. Know your workload before you buy.
