Intel Xeon E5-2689 8-core LGA 2011-3

The Xeon E5-2689 is an eight-core server chip from the Sandy Bridge-EP era that still holds up for multi-threaded work. Its PassMark multi-thread score of 9,413 is respectable for the price, but the single-thread score of 1,580 is a real drag. At around $110 USD, it's a decent buy for home servers and budget workstations if you already have an LGA 2011-3 board. For gaming or daily use, skip it and save for something modern.

The PassMark numbers tell a pretty clear story. Multi-threaded performance lands at 9,413, which puts it right around the middle of the pack for CPUs in our database. That's not bad for a chip this old. You're getting roughly the multi-core grunt of a modern budget six-core, which means video encoding, file compression, and running a handful of VMs are all totally doable. The 20MB of L3 cache helps keep those eight cores fed without constantly hitting RAM.

Single-threaded performance is where the age really shows. A score of 1,580 puts it in the bottom third of everything we track. That 2.6GHz base clock, with no meaningful turbo to speak of, means anything that relies on one fast core is going to feel sluggish. Opening apps, navigating Windows, and most games will all feel noticeably slower than even a $100 modern chip. The 115W TDP is also worth mentioning. It's not terrible for eight cores from this era, but you're getting a lot less work per watt than anything made in the last five years.

The AMD Ryzen 7 7800X3D is the obvious elephant in the room. It's in a completely different universe, with single-thread performance that makes the E5-2689 look like it's running through molasses. But it also costs several times more. The comparison isn't really fair, but it does highlight what you're giving up. The 7800X3D is a modern gaming monster, while the E5-2689 scores 18 out of 100 for gaming. If you care about frame rates at all, this Xeon is not your chip.

More realistic comparisons are the Dell Xeon E5-2637 V2 and the PC Server and Parts E5-2697 v2. The E5-2637 V2 is a quad-core with higher clocks, so it'll feel snappier in day-to-day tasks but fall behind in heavily threaded work. The E5-2697 v2 is the big brother, with more cores and cache, but it also costs more and pulls more power. The E5-2689 sits in a sweet spot between them, offering a decent core count without the premium price of the higher-end Xeons.

At $110 USD, the value proposition is genuinely interesting if you already have a compatible motherboard. You're getting eight cores and 20MB of cache for less than the price of a new budget quad-core. For a home server or a cheap rendering box, that's hard to argue with. The affordability percentile of 67 means it's cheaper than about two-thirds of the CPUs we track, which is a real selling point.

But the value math falls apart if you're starting from scratch. You'll need to hunt down a used LGA 2011-3 board, which can cost as much as the chip itself. Then you need DDR4 ECC or non-ECC memory, a cooler that handles 115W, and a power supply with the right connectors. By the time you add all that up, you're often within spitting distance of a modern Ryzen or Core i5 setup that will run circles around this thing in every metric.

The Intel Xeon E5-2689 is one of those chips that makes you do a double take. It's a server processor from the Sandy Bridge-EP era, but it's been showing up in budget gaming and workstation builds for years now. Eight cores, 20MB of L3 cache, and a 2.6GHz base clock. On paper, it sounds like a lot of chip for not much money. And honestly, for the right person, it kind of is.

This thing is aimed at people who want a cheap multi-core workhorse. Think home servers, budget rendering boxes, or someone who found an old LGA 2011-3 motherboard gathering dust and wants to breathe some life into it. The 115W TDP tells you it's not exactly sipping power, but it's also not the space heater some of the higher-end Xeons turned into.

The interesting part is the price. We're seeing it listed around $110 USD, which puts it in a weird spot. You're getting eight cores and a pile of cache for less than the cost of a decent dinner for two. But you're also buying into a platform that's over a decade old, with all the quirks that come with that.

Gamers should absolutely skip this chip. The gaming score of 18 out of 100 is one of the worst we've seen, and the single-thread performance will bottleneck even mid-range GPUs. If you're building a gaming PC, look at a modern Ryzen 5 or Core i5 instead. You'll spend more, but the difference in frame rates and overall responsiveness will be night and day.

Anyone building a new system from scratch should also think twice. The LGA 2011-3 platform is a dead end, with no upgrade path to newer CPUs. You'll be buying used motherboards, hunting for compatible RAM, and dealing with the quirks of a decade-old platform. For most people, a modern budget build with a Ryzen 5 or Core i3 will be faster, more efficient, and easier to live with.

If you're building a budget home server, a NAS that needs some actual compute, or a cheap rendering box and you already have an LGA 2011-3 motherboard, the E5-2689 is a solid pick. Eight cores and 20MB of cache for around $110 USD is a genuinely good deal for those workloads. You'll be able to run Plex, handle a few VMs, and crunch through video encodes without breaking a sweat.

But if this is going to be your daily driver, or if you're hoping to game on it, look elsewhere. The single-thread performance is rough, and the platform is a dead end. You'd be better off saving up for a modern budget chip like a Ryzen 5 or Core i5. They'll cost more upfront, but you'll get a platform with an upgrade path, dramatically better single-thread speed, and a fraction of the power draw.
