Description of the processor
The Intel Core i7-8700K is a real racer and ideal for users who need a lot of computing power. Not only does the processor from Intels Core i7 series have 6 cores that clock with 3.70 GHz each in normal mode and can increase to 4.70 GHz (single core load) or 4.30 GHz (multi-core load) in turbo mode, but the "K" at the end of the processors name also indicates that the clock can be changed manually. This means that you can overclock the processor as high as you want, provided there is sufficient cooling.Furthermore, the Intel Core i7-8700K can fall back on a large L3 cache of 12 megabytes and supports the following virtualization technologies from Intel: VT-x, VT-x EPT, VT-d.
The Intel Core i7-8700K, which is based on the Intel "Coffee Lake" architecture and manufactured in the 14 nanometer process, also supports the AES-NI encryption with which, for example, the hard disk of a company laptop can be encrypted in hardware.
The Intel Core i7-8700K requires a motherboard with socket LGA 1151-2 and a matching CPU cooler. If you consider overclocking the processor, you should pay attention to the quality of the CPU cooler. For example, Noctua or BeQuiet coolers are ideal for overclocking and they are also particularly quiet when the processor is under low load. However, the ideal combination of low noise and optimal cooling can only be achieved with water cooling. Only the water pump still makes a noise here, and theoretically you can install it too damped so that nothing can be heard.
The Intel Core i7-8700Ks codec support leaves almost nothing to be desired. All common codecs can be decoded in hardware. The CPU restricts itself to the most important codecs during encoding, and so the "VP9" and "VC-1" codecs are used for decoding.
