New Intel Core i5-13600K and Core i7-13700K benchmarks showcase excellent performance gains over Alder Lake

Most processors belonging to Intel's upcoming 13th-generation Raptor Lake family have leaked in some capacity. Among other things, they will pack brand new Raptor Cove performance cores but reuse the same Gracemont efficiency cores. The Intel Core i5-13600K, Core i7-13700K and Core i9-13900K will be the first three CPUs to break cover in late September. Extreme Player, a renowned Bilibili leaker, has put the Core i5 and Core i7 SKU through a full suite of benchmarks and stumbled upon some interesting results.

Starting with the benchmark built into the CPU-Z application, the Intel Core i7-13700K is 10% faster than the Core i7-12700K in single-core performance and up to 34% in multi-core performance. The Intel Core i5-13600K is about 5% and up to 39% faster than the Core i5-12600K in the same benchmark. That trend continues in Geekbench, with the Core i7 SKU outdoing its previous-generation counterpart by up to 8% in single-threaded workloads and 40% in multi-threaded performance. Geekbench and CPU-Z don't load the CPU for long enough, hence are not ideal indicators of how a CPU would perform under sustained load. In Cinebench R23 the Intel Core i7-13700K outclasses the Core i7-12700K by 10% in the single-core test and by up to 28% in the multi-core test. The Core i5-13600K posts similar results with a 5% and 38% improvement over the Core i5-12600K.

Other tests, such as 3D Mark, 7Zip, Puget bench and Blender tell a similar story. This isn't surprising, given the clock speed increases across both SKUs. The Intel Core i7-13700K's P cores are now clocked at 4.3 GHz (vs 3.8 GHz) and the E cores at 3.4 GHz (vs 2.7 GHz). Similarly, the Intel Core i5-13600K runs its P cores at 3.9 GHz (vs 3.6 GHz) and E cores at 3.5 GHz (vs 2.8 GHz). Furthermore, both the Core i5-13600K and Core i7-13700K feature a total of eight E cores, double what was found on their Alder Lake counterparts. The amount of cache on both processors has been increased as well.

All of this extra performance, however, comes with a corresponding rise in power consumption. The Core i7-13700K drew as much as 244 Watts of power from the wall while the Core i5-13600K went as high as 177 Watts. It is clear that Raptor Lake is quite power hungry and will require beefy cooling. That, combined with Nvidia's monstrous 800W GPU could bring even the best power supply to its knees.
