About the Intel Atom Z3745 CPU
The Intel Atom Z3745 is a 4-core (4-thread) processor built for the mobile CPU market. The Z3745 is compatible with UTFCBGA1380 motherboards and is fabricated on a 22 nm manufacturing process.
Memory and Cache
In terms of cache, the Atom Z3745 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 Z3745 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 1860.0 MHz under heavy workloads. Higher clock speeds result in better performance for the same microarchitecture.
Integrated Graphics
The Atom Z3745 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 Z3745 has the 686th best 3DMark 11 Performance Physics score among the 721 benchmarked CPUs in our database. It achieves 3.41% of the performance of the best benchmarked CPU, the AMD Ryzen 9 7950X3D.
About the Intel Core i5-450M CPU
The Intel Core i5-450M is an end-of-life 2-core (4-thread) processor built for the mobile CPU market. It launched in Q3 2010. It is part of Intel's Core i5 lineup, which is based on the Arrandale microarchitecture. The i5-450M is compatible with Intel Socket G1 motherboards and is fabricated on Intel's 32 nm manufacturing process.
Memory and Cache
The Core i5-450M supports DDR3 memory. In terms of cache, the Core i5-450M 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 256 KB, is larger but slower than the L1. Its L3 cache, a shared resource among the CPU's cores, has a capacity of 3 MB.
Cores and Clock Speeds
The Core i5-450M features 2 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 2.4 GHz, and it can boost up to 2.7 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 Core i5-450M 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 Core i5-450M has the 594th best 3DMark 11 Performance Physics score among the 721 benchmarked CPUs in our database. It achieves 6.01% of the performance of the best benchmarked CPU, the AMD Ryzen 9 7950X3D.
