About the AMD A6-6400K CPU

The AMD A6-6400K is an end-of-life 2-core (2-thread) processor built for the desktop CPU market. It launched in Q2 2013. It is part of AMD's A6 lineup, which is based on the Richland microarchitecture. The A6-6400K is compatible with AMD Socket FM2 motherboards and is fabricated on GlobalFoundries's 32 nm manufacturing process. It features the Radeon HD 8470D integrated graphics solution.

Memory and Cache

The A6-6400K supports DDR3 memory and features a dual-channel memory controller, allowing it to utilize 2 memory modules simultaneously. In terms of cache, the A6-6400K has multiple levels of cache. Its L1 cache, which is the smallest and fastest, is 96 KB in size, providing rapid access to crucial instructions. Its L2 cache, at 1 MB, is larger but slower than the L1.

Cores and Clock Speeds

The A6-6400K features 2 total cores which can process 2 threads simultaneously. The multi-threading capability allows the CPU to execute multiple computational tasks in parallel. The base clock speed of the CPU is 3.9 GHz, and it can boost up to 4.1 GHz under heavy workloads. Higher clock speeds result in better performance for the same microarchitecture. The multiplier is unlocked, enabling overclocking for those seeking to push the CPU's performance further.

Integrated Graphics

The A6-6400K includes an integrated graphics solution called Radeon HD 8470D. This graphics processor is directly integrated into the CPU and is not as powerful as a dedicated graphics card. While integrated graphics can handle basic tasks like web browsing and office applications, it is not suitable for more demanding activities such as gaming or video editing, where a dedicated graphics card offers superior performance.

Benchmark Performance

The A6-6400K has the 615th best 3DMark 11 Performance Physics score among the 721 benchmarked CPUs in our database. It achieves 5.40% of the performance of the best benchmarked CPU, the AMD Ryzen 9 7950X3D.

About the AMD Ryzen 9 7950X3D CPU
