Intel Core i7-8700K vs Intel Core i5-8500T
Intel Core i7-8700K
► remove from comparison
The Intel Core i7-8700K is a high-end desktop processor with six cores based on the Coffee Lake architecture and was announced in September 2017. The processor clocks at between 3.7 and 4.7 GHz and can execute up to twelve threads simultaneously thanks to Hyper-Threading. According to Intel, the CPU is manufactured in an improved 14nm (14nm++) process. The i7-8700K is comparatively easy to overclock thanks to the unlocked multiplier.
Performance
Due to the two additional cores, performance has increased by almost 50% compared to the Core i7-7700K when all cores are in use. Single-core performance has not improved since its Kaby Lake predecessor. As a high-end model, the i7-8700K is suitable for the most demanding applications and games.
Graphics
The integrated Intel UHD Graphics 630 iGPU is supposed to offer higher performance as its clock rate has been increased by 50 MHz. The build is identical to that of the Intel HD Graphics 630. We do expect a performance improvement, but as a low-end solution it will probably only display current games smoothly at reduced details - if at all.
Power Consumption
Intel specifies the TDP with 95 watts. Therefore, well-dimensioned cooling systems should easily manage to deal with the created heat. We expect increased efficiency due to the higher performance.
Intel Core i5-8500T
► remove from comparisonThe Intel Core i5-8500T is a desktop processor of the Coffee Lake generation. It offers 6 cores clocked at 2.1 - 3.5 GHz and is manufactured in the again improved 14nm process (14nm++). As a "T" model, te i5-8500T is rated with a low 35 Watt TDP and therefore sometimes even used in laptops.
Thanks to the additional 2 cores, the Coffee Lake 6-core CPUs can offer a performance uplift of up to 50% in multithreaded workloads compared to the Kaby Lake predecessors.
