Intel Core i9-9900KS vs Intel Core i7-9700 vs Intel Core i5-9600K
Intel Core i9-9900KS
► remove from comparison
The Intel Core i9-9900KS is a high end desktop processor that includes 8 cores based on the Coffee Lake architecture. It is the fastest Coffee Lake CPU in 2019 and compared to the similar named i9-9900K, the KS offers an all core Turbo of 5 GHz. All cores can clock between 4 GHz and 5 GHz and thanks to Hyperthreading / SMT 16 threads can be executed in parallel. The CPU is still manufactured in the mature 14 nm process (14nm++). Thanks to the open multiplicator, the CPU is rather easy to overclock (if a Z390 based mainboard is used).
With good cooling, the i9-9900KS can be around 10% faster than the older Intel Core i9-9900K (thanks to the 5 GHz all core Turbo). Compare to the old Core i7-8700K, the 9900KS is even 45% faster. Especially for gaming, the 9900KS is currently the fastest option available. The fast Ryzen and Threadripper CPUs from AMD however offer a better multithreaded performance.
The integrated GPU is called Intel UHD Graphics 630 and clocks with up to 1.2 GHz. It is not suited for demanding 3D games and located in the low end.
The TDP is raised to 127 Watt for the additional performance, therefore a good CPU cooler is needed. When overclocking the CPU, more than 200 Watt can be reached unter load.
Intel Core i7-9700
► remove from comparison
The Intel Core i7-9700 is a high end desktop processor based on the Coffee Lake architecture. It integrates 8 cores (no Hyperthreading therefore also 8 threads) clocked at 3 - 4.7 GHz. Compared to the similar named Core i7-9700K, the 9700 has no open multiplicator for easy overclocking, offers lower clock speeds and offers a reduced TDP.
Compared to the old Core i7-8700, the 9700 offers two more real cores but no Hyperthreading. Therefore, the performance gain is not that big - depending on the app. The single core performance was slightly improved thanks to the higher Turbo clocks. As a high end desktop CPU, the i7-9700 is well suited for demanding tasks and 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 65 Watt (instead of the 95W of the faster models) and therefore the CPU wont need a high end desktop cooling system.
Intel Core i5-9600K
► remove from comparisonThe Intel Core i5-9600K is a high end desktop processor based on the Coffee Lake architecture. It offers an open multiplicator for easy overclocking and integrates 6 cores (no Hyperthreading therefore also 6 threads) clocked at 3.7 - 4.6 GHz and it needs a new Z390 based mainboard. It is manufactured in the second iteration of the improved 14nm process (14nm++).
Compared to the older Core i5-8600K, the 9600K offers about 10 to 15% higher performance. As the CPU still offers 6 cores and threads, the improvements are mostly due to the higher clock speeds. As a fast mid range desktop CPU, the i5-9600K 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 1.15 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 150 Watt and higher.
