The i7-2600K is a desktop CPU, the i3-8121U is a laptop CPU. A recent desktop i3 is clearly faster: https://www.anandtech.com/bench/product/2277?vs=2413 https:

  And not only that. The K series is the unlocked high-performance version of the desktop series. Whereas U is the low-voltage/ultrabook version of the mobile series. So they are sitting pretty much at the opposite end of the spectrum (if we remove server and phone CPUs from the picture), and it's no huge surprise that it still shows up as faster.

  And the difference is going to rocket up a lot pretty soon, as the next i3 will have 4 cores/8 threads.

  > The i7-2600K is a desktop CPU, the i3-8121U is a laptop CPU. The i3-8121U is a low-power CPU. Low-power processors often end up in desktops like the Mac Mini (which doesn't use that specific model but has used U-series processors) or the Intel NUC (which uses that exact CPU): https://www.newegg.com/intel-nuc-8-home-boxnuc8i3cysm1-student-home-office/p/3C6-008J-00002 https://www.newegg.com/intel-nuc-8-home-boxnuc8i3cysm1-stude... Meanwhile the i3-8350K is the top end i3 which has the same number of cores and cache and a higher clock speed than the i7-2600K. No surprise it wins when the only thing it really lacks is hyperthreading, and even that causes it to lose some of the threaded tests. The point was that e.g. an old quad core could often beat a new dual core. Every new dual core i3 is low-power, but if you want to see the 2600K acquitting itself well against a modern dual core "desktop" processor, here you are: https://www.anandtech.com/bench/product/2268?vs=2413 https://www.anandtech.com/bench/product/2268?vs=2413
