In our testing of the Core i9-12900K, we found massive gains over the previous generation and a significant lead over the competing Ryzen 9 5950X. With Alder Lake finally here, we can validate some of Intel’s performance claims. A rumor from November revealed a slate of chips joining in 2022, some of which ditch the E-cores in favor of all P-cores. We’ll see more, but for right now, all we have are rumors. The six chips above are the ones that Intel has already released. With Intel’s updated Extreme Overclocking Utility (XTU), you can tweak the P-cores and E-cores independently to dial in an overclock. The P-cores and E-cores run at different frequencies, so there isn’t a single number to reference. Intel has stressed the efficiency of the new design, saying the i9-12900K can deliver the same peak multi-threaded performance as the i9-11900K while consuming only 65W.įrequency-wise, it’s hard to lock Alder Lake down. Still, that’s technically less than the Core i9-11900K, which could boost as high as 250W when pushed. The flagship Core i9-12900K can climb as high as 241W when boosting. Only the P-cores support hyperthreading, so the i9 model comes with 16 cores and 24 threads, the i7 model comes with 12 cores and 20 threads, and so on.Īll of the chips come with a 125-watt rated power limit, though they can boost much higher. Here’s how the range looks at the moment:Īll of the chips come with a mix of P-cores and E-cores, but the balance is different for each model. They confirm earlier rumors overall, with the top chip sporting 16 cores split evenly across P-cores and E-cores. With the release of the first Alder Lake processors, we have our first look at the specs.

The box designs are mostly unchanged from the previous generation, however, the flagship Core i9-12900K comes slotted inside a golden wafer replica in the box, confirming an earlier leak. That’s the only difference between the chips, so the Core i9-12900K and Core i9-12900KF should be identical in terms of CPU performance. The K-series chips are more expensive because they feature integrated graphics, which the KF-series chips do not. The i9 and i5 models have seen a slight bump, while the i7’s pricing is the same as the previous generation.Īlthough there are six processors available, they come in groups of two. At least in the U.S., Intel didn’t raise prices much over 11th-gen chips. Earlier leaks pointed to prices nearing $1,000 for the flagship chip. The prices are much lower than we expected. They’re split into three groups of two, with a K-series and KF-series model available for each SKU:

The company announced them during the Intel Innovation event on October 27, revealing six new CPUs to kick off the range. The first batch of Alder Lake chips arrived on November 4, though we should see more products in the future.
