Both models
i7-9700K and
i7-9700K are based on
Coffee Lake architecture.
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 i7-9700K gets a score of
494.4 k points while the i7-9700K gets
460 k points.
Summarizing, the
i7-9700K is
1.1 times faster than the
i7-9700K. To get a proper comparison between both models, take a look to the data shown below.
