About the AMD A9-9420 CPU
The AMD A9-9420 is an end-of-life 2-core (2-thread) processor built for the mobile CPU market. It launched in Q2 2016. It is part of AMD's A9 lineup, which is based on the Stoney Ridge microarchitecture. The A9-9420 is compatible with AMD Socket FT4 motherboards and is fabricated on GlobalFoundries's 28 nm manufacturing process. It features the Radeon R5 3CU integrated graphics solution.
Memory and Cache
The A9-9420 supports DDR4 memory and features a single-channel memory controller, allowing it to utilize 1 memory modules simultaneously. In terms of cache, the A9-9420 has multiple levels of cache. Its L1 cache, which is the smallest and fastest, is 160 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 A9-9420 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 3.0 GHz, and it can boost up to 3.6 GHz under heavy workloads. Higher clock speeds result in better performance for the same microarchitecture. The multiplier is locked, making it incapable of overclocking for pushing performance further.
Integrated Graphics
The A9-9420 includes an integrated graphics solution called Radeon R5 3CU. 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 A9-9420 has the 654th best 3DMark 11 Performance Physics score among the 721 benchmarked CPUs in our database. It achieves 4.41% of the performance of the best benchmarked CPU, the AMD Ryzen 9 7950X3D.
About the AMD A8-4555M CPU
The AMD A8-4555M is an end-of-life 4-core (4-thread) processor built for the mobile CPU market. It launched in Q3 2012. It is part of AMD's A8 lineup, which is based on the Trinity microarchitecture. The A8-4555M is compatible with AMD Socket FP2 motherboards and is fabricated on GlobalFoundries's 32 nm manufacturing process. It features the Radeon HD 7600G integrated graphics solution.
Memory and Cache
The A8-4555M supports DDR3 memory and features a dual-channel memory controller, allowing it to utilize 2 memory modules simultaneously. In terms of cache, the A8-4555M 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 A8-4555M 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 1600.0 MHz, and it can boost up to 2.4 GHz under heavy workloads. Higher clock speeds result in better performance for the same microarchitecture. The multiplier is locked, making it incapable of overclocking for pushing performance further.
