Unknown Unknown
In terms of performance, processors of the Core i7 family have seldom been so close to the processors of the Core i9 family as in the 11th generation. You can quickly see this when you compare the performance in benchmarks of the Intel Core i9-11900K against the Intel Core i7-11700K. This is because Intel no longer defines 10 cores as a maximum in the 11th generation of the Core i desktop processors, but only 8.

The Intel Core i9-11900K therefore only has 8 CPU cores and thus 2 less than its direct predecessor. The Intel Core i7-11700K remains like its predecessor with 8 CPU cores.

Since the base clock of the Intel Core i7-11700K only differs by 100 MHz from that of the Intel Core i9-11900K (3.4 GHz to 3.5 GHz), and the turbo frequencies are very similar (200-300 MHz deviation in favor of the Core i9), in the end there is only a very small increase in performance for the Intel Core i9-11900K. This is around 2-3 percent compared to the Intel Core i7.

The iGPU (internal graphics) of the two processors is also identical. An Intel Iris Xe Graphics 32 (Rocket Lake S) with 32 execution units (a maximum of 96 units would be possible in the largest expansion stage) and 256 shaders is used. With a computing power of around 0.7 TFLOPS, the graphics card is not even suitable for older games. It is positive that the new AV1 video codec can be decoded in hardware by the iGPU, which significantly reduces the system load when watching AV1-encoded videos.

Both desktop processors can address a maximum of 128 GB of DDR4-3200 RAM. Two memory channels (dual-channel mode) are supported in a maximum of 4 working memory modules. The memory's ECC error correction function is not supported.

The processors support PCIe 4.0, whereby the Intel Core i9 has 20 internal lines and the Intel Core i7 has only 16 lines. So if you want to connect a fast PCIe 4.0 x4 M.2 SSD to the system, you should pay attention to a suitable mainboard chipset with the Intel Core i7.
