Intel Core i7-6700K

The Core i7-6700K is a 4 core CPU from Intel released in 2015. This chip has a very good overall score at 44% in our CPU benchmark. Our gaming benchmark shows that this CPU is a very good processor for gaming, with a score of 69%. As for multitasking and heavy workloads, the Core i7-6700K scores 36% and 35% respectively. Indeed, this is a good rating for very heavy workloads.

The Core i7-6700K has 4 cores and 8 threads. This CPU makes use of simultaneous multithreading technology to improve performance on parallel tasks. Each physical CPU core is divided into multiple logical processors. This Intel CPU has a clock speed of 4 GHz and a turbo speed of 4.2 GHz : a higher clock speed that can be reached when thermals and power delivery allow. This CPU has a locked multiplier, so you are not able to overclock it beyond this frequency.

As for memory, the Core i7-6700K makes use of DDR4-1866 memory. The faster the memory, the better. Faster memory means that the CPU doesn't have to wait to get the data it needs. It can accommodate a maximum of 64 GiB of memory. Furthermore, this chip can handle up to 2 channels of RAM, a multichannel memory architecture allows for higher data transfer between the CPU and the memory. However, to take advantage of this, you must have enough memory slots filled. Error correcting memory is not supported on this processor.

In terms of cache, the Core i7-6700K has 256 KiB of level 1 cache, 1 MiB of level 2 cache and 8 MiB of level 3 cache. This is a fast memory located close to the processor, which stores copies of frequently used data from main memory.

This CPU has fast connectivity with support for PCI-Express Gen 3. The faster the PCIe link, the better. This allows for better performance with GPUs and NVME SSDs. It has a total of 16 PCIe lanes.

Power and thermals for the Intel Core i7-6700K CPU are a TDP (Thermal Design Power) of 95 watts. This measures the amount of heat the processor produces when running at full load. This isn't a measure of power consumption, but it's good estimate.
