The A6-6400K is a 1 core CPU from AMD released in 2013. This chip has a bad overall score at 9% in our CPU benchmark. Our gaming benchmark shows that this CPU is an average processor for gaming, with a score of 19%. As for multitasking and heavy workloads, the A6-6400K scores 6% and 6% respectively. Indeed, this is a bad rating for very heavy workloads.
The A6-6400K has 1 cores and 2 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 AMD CPU has a clock speed of 3.9 GHz and a turbo speed of 4.1 GHz : a higher clock speed that can be reached when thermals and power delivery allow. This CPU has an unlocked multiplier and allows for overclocking. With adequate cooling and a good power supply, it's possible to run this CPU at a higher clock speed.
As for memory, the A6-6400K makes use of DDR3 memory. The faster the memory, the better. Faster memory means that the CPU doesn't have to wait to get the data it needs. 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.
In terms of cache, the A6-6400K has 96 KiB of level 1 cache, 1 MiB of level 2 cache. This is a fast memory located close to the processor, which stores copies of frequently used data from main memory.
Power and thermals for the AMD A6-6400K CPU are a TDP (Thermal Design Power) of 65 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.
