Intel Core i9 10900 10-core LGA 1200

The Intel Core i9-10900F is a 10-core, 20-thread desktop CPU that still delivers strong gaming and productivity performance in 2025. It's a killer drop-in upgrade for existing LGA 1200 owners, especially at the lower end of its CAD 339 to CAD 417 price spread. But the dead socket, PCIe 3.0, and lack of integrated graphics make it a tough sell for new builds.

The 10900F posts a PassMark multi-thread score of 19,649 and a single-thread score of 3,022. In our database, that puts multi-thread performance well above average for desktop CPUs, and single-thread lands in strong territory too. For a 65W part, that's genuinely impressive. Intel's Turbo Boost Max 3.0 helps the best cores hit 5.2GHz, and under sustained all-core loads you'll typically see it settle around 4.6GHz, which is still plenty fast.

In practice, this chip chews through video encodes, code compiles, and heavy multitasking without breaking a sweat. The 20MB of L3 cache helps with gaming frame consistency, and the 10 physical cores mean you can stream, record, and game at the same time without stutter. Efficiency is a standout here, ranking near the top of our charts for a chip of this class. The catch is that it's still PCIe 3.0 only, so you won't get Gen4 SSD speeds, and memory is capped at DDR4. For most people, that's a non-issue. For someone chasing maximum storage throughput, it's a limitation worth knowing about.

Stacked against the AMD Ryzen 7 9800X3D, the 10900F gets absolutely smoked in gaming. The 9800X3D's 3D V-Cache is a different league entirely, and it's on AM5 with DDR5 and PCIe 5.0. But that chip also costs a lot more, so it's not really a fair fight. The more honest comparison is against other 10th Gen Intel parts. The i7-10700K gives you 8 cores and overclocking headroom, but the 10900F beats it in multi-threaded workloads out of the box. The i9-10850K is basically the same silicon with a higher TDP and unlocked multiplier, so if you find one cheaper, grab it instead.

Against older AMD stuff like the Ryzen 5 3600, the 10900F is a clear step up. The owner review mentioning a 40 FPS gain in Warzone at 1440p tells the story. But against a Ryzen 7 5700X or 5800X, the gap narrows considerably, and those AM4 chips have a better upgrade path to the 5800X3D. The 10900F is a great chip in a vacuum. It's the platform around it that holds it back.

Value is where the 10900F gets interesting. In Canada, prices swing from CAD 339 to CAD 417 across two listings, and the lower end of that spread is the one to chase. Newegg currently has the better deal on the refurbished side, while Amazon's listing tends to sit higher. At USD 279 in the US, it's a tougher sell when you can get a Ryzen 5 7600 or even a used 5800X3D for not much more on a platform with actual longevity. But if you already own an LGA 1200 board and you're coming from something like an i5-10400, this is a drop-in upgrade that transforms your system. The math works best for people upgrading in place, not building from scratch.

The Intel Core i9-10900F is a 10th Gen Comet Lake desktop processor that sits in a weird spot in 2025. It's a 10-core, 20-thread chip with a 5.2GHz boost clock and a 65W TDP, and it's aimed at people who want serious multi-threaded muscle without jumping to a newer platform. The 'F' means no integrated graphics, so you'll need a discrete GPU. That's fine for most builders, but it's worth knowing before you buy. Prices are all over the place depending on where you shop, from CAD 339 to CAD 417 in Canada alone, and around USD 279 in the US.

People searching for this chip usually want to know two things: is it still good for gaming, and is it worth buying used or refurbished on a budget. The short answer is yes on gaming, with caveats. The 10900F still pushes high frame rates in most titles, especially at 1440p where the GPU does more of the heavy lifting. One owner reported a 40 FPS jump in Warzone at 1440p competitive settings coming from a Ryzen 5 3600. That's a real upgrade for someone on an older AM4 rig.

But here's the thing. This is a 14nm chip from 2020 on a dead socket. LGA 1200 means you're locked into 400-series motherboards, and there's no upgrade path to 11th Gen without a board swap. If you're building fresh, you should think hard about whether a used 10900F plus a compatible board actually saves you money versus a modern budget platform. Sometimes it does. Sometimes it doesn't.

Skip the 10900F if you're building a new PC from scratch and don't already own an LGA 1200 motherboard. The platform is dead, PCIe 3.0 limits fast SSD performance, and there's no integrated graphics as a safety net. You're better off with a Ryzen 5 7600 or Core i5-13400 on a current socket. Also skip it if you need Gen4 SSD speeds or want a CPU with an upgrade path. And if you're sensitive about warranty coverage, the refurbished listings on Newegg might leave you with more questions than answers.

Should you buy the Intel Core i9-10900F? If you already have an LGA 1200 motherboard and you're running something like an i3 or i5 from the same generation, yes. This is one of the best drop-in upgrades you can make on that socket, and the 65W TDP means your existing cooler probably handles it fine. The performance jump in gaming and productivity is real, and the price on the used market keeps dropping.

If you're building a new system from scratch, I'd steer you elsewhere. The LGA 1200 platform is a dead end, PCIe 3.0 is aging, and there's no integrated graphics as a fallback. A modern Ryzen 5 or Core i5 on a current socket will serve you better long-term, even if it costs a bit more up front. The 10900F is a fantastic upgrade chip and a questionable foundation.
