I'm going to build a computer, but I'm stuck on choosing a processor. I found two processors: Intel Core i7-9700K and i7-9750H. The 9750H, according to the official site, is a bit faster and has more threads. But, on Intel's website it's marked as Mobile. Does that mean it's incompatible or it's not recommended to use it in a desktop computer? If that's the case, can 9700K fill up like everything from gaming through 3D animation to programming?

  • the 9750H is a CPU only found on laptops, that's why it's meant as "mobile", go with the 9700k – CaldeiraG Dec 6 '19 at 8:40
  • Why build an Intel system nowadays? Was the price lowered significantly? – Jan Dorniak Dec 6 '19 at 23:39

The 9750H is a mobile processor, meant to be soldered to a laptop motherboard. It will not fit in a a desktop motherboard, nor will you be able to buy one. So for a desktop you don't have a choice. Unless you buy a notebook.

That said, why would you buy the 9700K now? According to benchmarks the cheaper Ryzen 7 3700X is slightly slower in some tasks (single or light threading), but can be significantly faster in others (heavily threaded).

That said, what you mostly care about, both for games and 3D is single core performance and the GPU. Games tend to be lightly threaded, same as mesh editing. For programming it depends on your language, although I suppose build in any language are paralleled nowadays. Autocompletion in the IDE is more of a single thread stuff as well.

As a side note - you definitely want an RTX. With both Blender and V-Ray supporting RTX it's a no-brainer as long as you have the budget. I've seen benchmarks where Blender render times were cut in half using hardware RT vs pure CUDA on the same card.
