About the AMD A6-4455M CPU
The AMD A6-4455M is an end-of-life 2-core (2-thread) processor built for the mobile CPU market. It launched in Q2 2012. It is part of AMD's A6 lineup, which is based on the Trinity microarchitecture. The A6-4455M is compatible with AMD Socket FP2 motherboards and is fabricated on GlobalFoundries's 32 nm manufacturing process. It features the Radeon HD 7500G integrated graphics solution.
Memory and Cache
The A6-4455M supports DDR3 memory and features a dual-channel memory controller, allowing it to utilize 2 memory modules simultaneously. In terms of cache, the A6-4455M has multiple levels of cache. Its L1 cache, which is the smallest and fastest, is 92 KB in size, providing rapid access to crucial instructions. Its L2 cache, at 2 MB, is larger but slower than the L1.
Cores and Clock Speeds
The A6-4455M 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 2.1 GHz, and it can boost up to 2.6 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 A6-4455M includes an integrated graphics solution called Radeon HD 7500G. 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 A6-4455M has the 689th best 3DMark 11 Performance Physics score among the 721 benchmarked CPUs in our database. It achieves 3.28% of the performance of the best benchmarked CPU, the AMD Ryzen 9 7950X3D.
About the Intel Atom Z3740 CPU
The Intel Atom Z3740 is an end-of-life 4-core (4-thread) processor built for the mobile CPU market. It launched in Q3 2013. It is part of Intel's Atom lineup, which is based on the Bay Trail-T microarchitecture. The Z3740 is compatible with Intel BGA 1380 motherboards and is fabricated on Intel's 22 nm manufacturing process. It features the HD Graphics integrated graphics solution.
Memory and Cache
The Atom Z3740 supports DDR3 memory and features a dual-channel memory controller, allowing it to utilize 2 memory modules simultaneously. In terms of cache, the Atom Z3740 has multiple levels of cache. Its L1 cache, which is the smallest and fastest, is 56 KB in size, providing rapid access to crucial instructions. Its L2 cache, at 2 MB, is larger but slower than the L1.
Cores and Clock Speeds
The Atom Z3740 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 1333.0 MHz, and it can boost up to 1867.0 MHz 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.
