I'm currently choosing parts for my new computer. I'm doing a lot of image processing and some of my algorithms are parallelized. In my free-time, I'm additionally up for some gaming.
My current system, although already built in 2011, runs an Intel Core i7-2700K with 4 real cores (8 HT) and 3.50GHz base frequency. This guy still rocks and looking through today's CPU's kind of give me the feeling that physical limitations for faster machines are clearly visible.
Apparently, the Intel Core i7-5820K with 6 cores (which is the 5th and not the 6th generation) is in many tests faster. Important for me is of course, that the CPU supports DDR4 memory, which it does.
Question: Taking into account that the prize is the same for both processors, I would be glad if someone had a recommendation. I'm keen to hear whether the difference in architecture (Skylake-S vs. Haswell-E) is somehow important for me. Probably there are other things I haven't considered.
