About the AMD A8-6600K CPU

The AMD A8-6600K is an end-of-life 4-core (4-thread) processor built for the desktop CPU market. It launched in Q2 2013. It is part of AMD's A8 lineup, which is based on the Richland microarchitecture. The A8-6600K is compatible with AMD Socket FM2 motherboards and is fabricated on GlobalFoundries's 32 nm manufacturing process. It features the Radeon HD 8570D integrated graphics solution.

Memory and Cache

The A8-6600K supports DDR3 memory and features a dual-channel memory controller, allowing it to utilize 2 memory modules simultaneously. In terms of cache, the A8-6600K has multiple levels of cache. Its L1 cache, which is the smallest and fastest, is 192 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 A8-6600K 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 3.9 GHz, and it can boost up to 4.2 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 A8-6600K includes an integrated graphics solution called Radeon HD 8570D. 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 A8-6600K has the 460th best 3DMark 11 Performance Physics score among the 721 benchmarked CPUs in our database. It achieves 10.66% of the performance of the best benchmarked CPU, the AMD Ryzen 9 7950X3D.

About the AMD Ryzen 9 3950X CPU

The AMD Ryzen 9 3950X is a 16-core (32-thread) processor built for the desktop CPU market. It launched in Q4 2019 with a suggested retail price of $749. It is part of AMD's Ryzen 9 lineup, which is based on the Zen 2 microarchitecture. The 3950X is compatible with AMD Socket AM4 motherboards and is fabricated on TSMC's 7 nm manufacturing process.

Memory and Cache

The Ryzen 9 3950X supports DDR4 memory and features a dual-channel memory controller, allowing it to utilize 2 memory modules simultaneously. In terms of cache, the Ryzen 9 3950X has multiple levels of cache. Its L1 cache, which is the smallest and fastest, is 64 KB in size, providing rapid access to crucial instructions. Its L2 cache, at 512 KB, is larger but slower than the L1. Its L3 cache, a shared resource among the CPU's cores, has a capacity of 64 MB.

Cores and Clock Speeds

The Ryzen 9 3950X features 16 total cores which can process 32 threads simultaneously. The multi-threading capability allows the CPU to execute multiple computational tasks in parallel. The base clock speed of the CPU is 3.5 GHz, and it can boost up to 4.7 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 Ryzen 9 3950X does not include an integrated graphics solution. A dedicated graphics card will be required if you require a monitor with your computer.

Benchmark Performance & Value

The Ryzen 9 3950X has the 63rd best 3DMark 11 Performance Physics score among the 721 benchmarked CPUs in our database. It achieves 56.81% of the performance of the best benchmarked CPU, the AMD Ryzen 9 7950X3D. Its 21,016 score and $749 launch price (MSRP) gives it a performance per dollar of 28.06. This is the 127th best in value for the 3DMark 11 Perf. Physics benchmark.
