About the Intel Celeron N2840 CPU
The Intel Celeron N2840 is a 2-core (2-thread) processor built for the mobile CPU market. It launched in Q2 2014. It is part of Intel's Celeron lineup, which is based on the Bay Trail microarchitecture. The N2840 is compatible with Intel BGA 1170 motherboards and is fabricated on Intel's 22 nm manufacturing process. It features the HD Graphics integrated graphics solution.
Memory and Cache
The Celeron N2840 supports DDR3 memory. In terms of cache, the Celeron N2840 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 512 KB, is larger but slower than the L1.
Cores and Clock Speeds
The Celeron N2840 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 2.2 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 Celeron N2840 includes an integrated graphics solution called HD Graphics. 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 Celeron N2840 has the 698th best 3DMark 11 Performance Physics score among the 721 benchmarked CPUs in our database. It achieves 2.90% of the performance of the best benchmarked CPU, the AMD Ryzen 9 7950X3D.
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.
