Intel Raptor Lake is finally here, and although there’s a handful of CPUs in this first wave of 13th-generation CPUs, it’s hard not to focus on the flagship, the Intel Core i9-13900K. Equipped with a seemingly endless number of cores, capable of hitting those ultra-high clock speeds, and socket-compatible with Alder Lake, it checks most of the boxes as far as the top-shelf CPUs are concerned.

But the 13900K is mostly just a refinement of the 12900K with extra cores. Is getting a Core i9-13900K worth the splurge, or should you keep things more budget-friendly with a 12th-gen CPU? Below, we’ll compare the two Intel flagships and help you choose a winner.

Pricing and availability

At the time of writing, the price of the 12900K has dropped from its initial $589 MSRP to anywhere between $500 and $550, such as on Amazon, where you can find it for just about $500. Still, it’s not cheap, and there are some AMD and Intel processors that offer better value, but it is what it is. These flagships are not meant to be cheap, anyway — they’re enthusiast-grade processors meant to deliver.

Despite rumors to the contrary, the Core i9-13900K is the same price as the Core i9-12900K — at least at launch, anyway. Given that the new CPU will become the de facto option at around $600, we expect the Core i9-12900K to slowly drop in price over the coming months. That could make a big difference in which processor you buy, especially if you can score a deal on a last-gen part.

The Core i9-12900K is available at most retailers now, while the Core i9-13900K will likely sell out close to launch and remain out of stock for a couple of weeks. That said, we don’t suspect any major shortages of the processor, so expect pricing to return to normal shortly after launch.

Specs

The Intel Core i9-13900K processor offers some very straightforward upgrades over the Core i9-12900K. With a higher core count, faster clock speeds, and a much larger cache, it has what it takes to deliver significantly better performance than the Alder Lake part. Let’s take a look at all the most important specs.

One thing to note about Raptor Lake’s eight extra cores is that these are efficiency cores, not performance cores. Otherwise, things are pretty straightforward because these two CPUs are almost identical architecturally.
