Intel Core i9 13900K 24-core LGA1700

The Core i9-13900K is a 24-core monster that tops our charts for both single-thread and multi-thread performance. It handles gaming, streaming, and heavy productivity without breaking a sweat, though it runs hot and needs a serious cooler. Prices range from USD 290 to USD 610, so shop around and grab it at the low end. If you're mostly gaming, the Ryzen 7 9800X3D is a cooler, more efficient alternative, but for mixed use, the 13900K is still a fantastic buy.

The PassMark numbers tell the story. 58,148 multi-thread and 4,597 single-thread put this chip in the top 5% of everything we've tested. In plain English, that means it handles video exports, 3D renders, and code compiles faster than almost anything else on the market. The single-thread score matters more for gaming and everyday responsiveness, and 4,597 is genuinely excellent. You won't feel this chip holding you back in any game at 1440p or 4K.

The 5.7GHz boost clock is the headline spec, but the real magic is how the E-cores handle background tasks. While the P-cores are maxed out on a game or render, the 16 efficiency cores quietly handle Windows updates, Discord, antivirus scans, and whatever else you've got running. That's why this chip feels smoother than older 8-core parts even when the raw gaming framerate is similar. The trade-off is power. At 253W turbo, this thing pulls serious wattage under load, and you'll need a beefy cooler to keep it from throttling.

The AMD Ryzen 7 9800X3D is the most interesting competitor right now. It's newer, runs cooler, and its 3D V-Cache gives it a real edge in gaming workloads. But it has fewer cores, so the 13900K still wins for heavy productivity and multitasking. If you're mostly gaming, the 9800X3D is probably the better buy. If you're splitting time between gaming and work, the 13900K's extra cores tip the scales back in Intel's favor.

The older Core i9-9900X from Intel's X-series line shows up in our competitor list too, but that's a different beast entirely. It's an HEDT chip with a different socket and different use case. The 13900K beats it in almost every metric that matters for a desktop user. And while the G.Skill Trident Z Neo and be quiet! Dark Rock Pro 5 aren't CPUs, they're worth mentioning because you'll need good RAM and a serious cooler to get the most out of this chip. Budget for both.

Pricing is all over the place right now. In the US, we're seeing listings from USD 290 to USD 610 across four vendors. That's a massive spread, and it means you should absolutely shop around before pulling the trigger. The USD 290 listing is a steal for this level of performance, while the USD 610 price is hard to justify when newer chips exist. In Canada, the spread is tighter at CAD 649 to CAD 794, but that's still a CAD 145 difference for the same silicon.

At the low end of that range, the 13900K is one of the best value propositions in desktop CPUs. You're getting flagship-class performance for mid-range money. At the high end, you're paying early-adopter prices for a chip that's been out for a while. Our advice: wait for a sale, grab it near the bottom of the range, and put the savings toward a good cooler and fast DDR5.

The Core i9-13900K is Intel's last big swing on the LGA 1700 socket, and it's a heck of a send-off. You get 24 cores split into 8 performance cores and 16 efficiency cores, with the P-cores boosting up to 5.7GHz. That hybrid design was Intel's answer to AMD's chiplet approach, and it works. The 13900K sits near the top of our database for both single-thread and multi-thread performance, which is a rare combo. Most chips are good at one or the other. This one just does both.

Who's this for? Gamers who also stream, edit video, compile code, or run a bunch of stuff at once. It's overkill for a pure gaming rig, but if you're the type who has Discord, OBS, a browser with 40 tabs, and a game running simultaneously, the extra E-cores earn their keep. The 36MB of L3 cache and 32MB of L2 cache help keep things snappy too.

There's a catch, though. This is the end of the road for LGA 1700. If you buy a 13900K today, there's no drop-in upgrade path to Intel's newer Arrow Lake chips. That's not a dealbreaker if you plan to keep this CPU for 4-5 years, but it's worth knowing before you commit.

If you're building a pure gaming PC and don't do video editing, 3D rendering, or heavy multitasking, the 13900K is more chip than you need. The Ryzen 7 9800X3D will give you better gaming framerates while running cooler and using less power. You'll also save money on cooling and potentially on the CPU itself.

If you already own a 12th-gen Intel chip like the 12700K or 12900K, the upgrade isn't as dramatic. The 13900K is faster, but not enough to justify the cost for most people. And if you're the type who upgrades CPUs every couple of years, the dead-end LGA 1700 socket means you'll need a new motherboard next time anyway. In that case, you might as well wait and jump to a newer platform when you're ready.

For a mixed-use desktop that handles gaming, streaming, and content creation, the 13900K is still one of the best choices you can make. The 24-core design means you never have to close anything, and the single-thread speed keeps games feeling snappy. If you're coming from an older Intel chip like a 9900K or 10900K, the upgrade is massive. Just make sure you have an LGA 1700 board and a cooler that can handle 253W.

If you're building a pure gaming rig and don't do much else, look at the Ryzen 7 9800X3D instead. It runs cooler, uses less power, and delivers better gaming framerates in most titles. But if you want one chip that does everything well, the 13900K at a good price is hard to beat. It's a swan song for LGA 1700, and it's a good one.
