About the Intel Atom Z3745D CPU
The Intel Atom Z3745D is a 4-core (4-thread) processor built for the mobile CPU market. The Atom Z3745D is fabricated on a 22 nm manufacturing process.
Memory and Cache
In terms of cache, the Atom Z3745D has multiple levels of cache. Its L1 cache, which is the smallest and fastest, is 224 KB in size, providing rapid access to crucial instructions. Its L2 cache, at 2 MB, is larger but slower than the L1. Its L3 cache, a shared resource among the CPU's cores, has a capacity of 0 MB.
Cores and Clock Speeds
The Atom Z3745D 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 1330.0 MHz, and it can boost up to 1830.0 MHz under heavy workloads. Higher clock speeds result in better performance for the same microarchitecture.
Integrated Graphics
The Atom Z3745D does not include an integrated graphics solution. A dedicated graphics card will be required if you require a monitor with your computer.
Benchmark Performance
The Atom Z3745D has the 679th best 3DMark 11 Performance Physics score among the 721 benchmarked CPUs in our database. It achieves 3.64% of the performance of the best benchmarked CPU, the AMD Ryzen 9 7950X3D.
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.
