The Core i9-9900KS 4.0 GHz 8-Core LGA 1151 Processor from Intel has been developed specifically for extreme gamers that want even more performance, as it delivers a maximum turbo frequency of up to 5.0 GHz on all eight of its cores. Built on the same foundation as the Core i9-9900K, the Core i9-9900KS delivers additional powerful multi-threaded performance on the Z390 platform without the need to upgrade your existing hardware. It has a base clock speed of 4.0 GHz, 8 cores and 16 threads in an LGA 1151 socket, has 16MB of Intel Smart Cache memory, and 40 PCIe lanes. Having 8 cores allows the processor to run multiple programs simultaneously without slowing down the system, while the 16 threads allow a basic ordered sequence of instructions to be passed through or processed by a single CPU core. This processor also supports dual-channel DDR4-2666 RAM.
Graphically, the Core i9-9900KS supported integrated processor graphics, so you won't need to buy a discrete graphics card. If you need even more performance, this processor is unlocked, which lets you overclock the processor over its maximum speed. However, this is not recommended, as it will void the limited 1-year warranty.
Please note that this processor does not include a heatsink or fan and requires a separately-sold CPU cooling solution.
