Celeron N3450 vs Core i7-2637M comparison

In our benchmarks, the Core i7-2637M beats the Celeron N3450 in overall performance. Furthermore, our gaming benchmark shows that it also outperforms the Celeron N3450 in all gaming tests too.

When comparing core counts for these CPUs, we notice that Celeron N3450 has significantly more cores with 4 compared to the Core i7-2637M that has 2. But they both have the same number of threads.

Our database shows that the Core i7-2637M has a significantly higher clock speed than the Celeron N3450.

A Celeron N3450 CPU outputs less heat than a Core i7-2637M CPU because of its significantly lower TDP. This measures the amount of heat they output and can be used to estimate power consumption.

In conclusion, all specs and CPU benchmarks considered, will recommend the Core i7-2637M over the Celeron N3450.

Use the table to the left to compare both the Celeron N3450 and the Core i7-2637M, the advantages and disadvantages of each are shown.

CPU rating

Our CPU rating is split into 4 categories: Overall, Gaming, Multitasking and Heavy Workloads. The overall score accesses performance using all CPU cores, gaming prioritises the first six cores, multitasking takes the first eight cores into account and finally heavy workloads are measured using a sixteen-core baseline.

Processor specifications

The more cores a CPU has, the better the overall performance will be in parallel workloads such as multitasking. Many CPUs have more threads than cores, this means that each physical core is split into multiple logical cores, making them more efficient. For instance, the Celeron N3450 has the same number of threads as cores. This means the the CPU does not support hyperthreading.

Clock speed and Turbo speed are important when comparing per core performance, generally the higher, the better. A higher clock speed may cause a higher TDP, however.

TDP (Thermal Design Power) is a measurement of how much energy is lost as heat when a processor is running. This has an impact on system temperatures. If temperatures get too high (typically around 100 °C or 200 °F), the CPU will lower its performance in order to prevent damage to the chip. Adequate cooling is essential for good performance.

Cache is very fast memory built into the processor. It stores what the CPU is currently working on and anything that doesn't fit is sent to the main system memory, which is slower but more plentiful. It is split into three levels, with Level 1 being the fastest and Level 3 being the slowest. More CPU cache is desirable for high-performance scenarios.
