Intel Core i9-9900K vs Intel Core i9-9900T

Intel Core i9-9900K

► remove from comparison

The Intel Core i9-9900K is a high end desktop processor based on the Coffee Lake architecture. At the time of announcement in late 2018, the 9900K is the fastest Coffee Lake CPU and offers an open multiplicator for easy overclocking. The CPU integrates 8 cores (16 threads) clocked at 3.6 - 5 GHz and it needs a new Z390 based mainboard.

Thanks to the two additional cores, the performance in multi-threaded applications is up to 25 % faster than the older Core i7-8700K. The single thread performance is only slightly faster due to the higher clock speeds. As a high end desktop CPU, the i9-9900K is suited even for very demanding applications and perfect for 3D gaming.

The integrated Intel UHD Graphics 630 graphics card is clocked at up to 1.2 GHz and offers no advantage compared to previous generations. As it is a very low end GPU, only some low demanding games like Hearthstone can be played with it (see GPU page for benchmarks).

Intel specifies the TDP at 95 Watt, so if the CPU is used in laptops a big and chunky cooling system is needed to avoid throttling and lower clock speeds under sustained loads. When overclocking the CPU, the power consumption can easily rise up to 200 Watt and higher.

Intel Core i9-9900T

► remove from comparison Intel i9-9900T

The Intel Core i9-9900T is a high end power efficient desktop processor based on the Coffee Lake architecture. Compared to the similar named top model Core i9-9900K, the 9900T offers lower clock speeds (2.1 - 4.4 GHz versus 3.6 - 5 GHz) and a reduced TDP of 35 versus 95 Watt. It still offers all 8 cores and 16 threads and is intended for small chassis or laptops.

The performance is clearly behind the Core i9-9900K and more in the realm of the older 6-core Coffee Lake CPUs.

The integrated Intel UHD Graphics 630 graphics card is clocked at up to 1.2 GHz and offers no advantage compared to previous generations. As it is a very low end GPU, only some low demanding games like Hearthstone can be played with it (see GPU page for benchmarks).
