About the AMD A8-7650K CPU
The AMD A8-7650K is an end-of-life 4-core (4-thread) processor built for the desktop CPU market. It launched in Q1 2015. It is part of AMD's A8 lineup, which is based on the Kaveri microarchitecture. The A8-7650K is compatible with AMD Socket FM2+ motherboards and is fabricated on GlobalFoundries's 28 nm manufacturing process. It features the Radeon R7 integrated graphics solution.
Memory and Cache
The A8-7650K supports DDR3 memory and features a dual-channel memory controller, allowing it to utilize 2 memory modules simultaneously. In terms of cache, the A8-7650K has multiple levels of cache. Its L1 cache, which is the smallest and fastest, is 256 KB in size, providing rapid access to crucial instructions. Its L2 cache, at 4 MB, is larger but slower than the L1.
Cores and Clock Speeds
The A8-7650K features 4 total cores which can process 4 threads simultaneously. The multi-threading capability allows the CPU to execute multiple computational tasks in parallel. The base clock speed of the CPU is 3.3 GHz, and it can boost up to 3.8 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 A8-7650K includes an integrated graphics solution called Radeon R7. 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 A8-7650K has the 473rd best 3DMark 11 Performance Physics score among the 721 benchmarked CPUs in our database. It achieves 10.12% of the performance of the best benchmarked CPU, the AMD Ryzen 9 7950X3D.
