Core i7-8700k


Description
The Core i7-8700k is a cpu manufactured by Intel released on October 2017. This model is based on Coffee Lake architecture which is the second refinement of Intel’s 14nm (Tri-Gate) technology. While it uses LGA1151 socket, it is incompatible with previous generations due to electrical changes in socket’s pins so these CPUs require Z370 chipset. This kind of generation introduced more cores in every range to compete with new AMD’s arquitecture. Coffee Lake uses DDR4 memory at 2400MHz for i3 and at 2666MHz for i5, i7 CPUs plus iGPU frequency has been increased 50MHz with respect to previous generation.

This model runs at 3700 MHz as base frequency but it can reach up to 4700 Mhz under some conditions with a thermal design power of 95 W. About its cache memory, this CPU has 6x32+6x32 kB level 1 cache, 6+256kB of level 2 cache and 12288kB of level 3 cache.

If we talk about optimized software, in its highest mode (mode III optimized for AVX2), the monothread score is 83880 and the multithread score is 477384 points.

There are some CPU models pretty similar to this one like the Intel Core i7-7700K , the Intel Core i7-8700 and the AMD Ryzen 7 2700X amongst others. To know the complete list and how similar are they, please go down on this page.
