Both models i7-8700k
are based on Coffee Lake
Coffee Lake 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 architecture. 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.
Using the multithread performance as a reference, the i7-8700k gets a score of 443.8 k points
while the i3-8100 gets 205.4 k points
Summarizing, the i7-8700k
is 2.2 times faster
than the i3-8100
. To get a proper comparison between both models, take a look to the data shown below.
