Celeron J4125 vs Core i7-2677M specs and performance

In our benchmarks, the Celeron J4125 beats the Core i7-2677M in overall performance. Furthermore, our gaming benchmark shows that it also outperforms the Core i7-2677M in all gaming tests too.

With info from our database, we find that the Celeron J4125 has significantly more cores with 4 cores whereas the Core i7-2677M has 2 cores. But they both have the same number of threads. Our comparison shows that the Celeron J4125 has a slightly higher clock speed compared to the Core i7-2677M. A Celeron J4125 CPU outputs less heat than a Core i7-2677M CPU because of its significantly lower TDP. This measures the amount of heat they output and can be used to estimate power consumption.

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 J4125 has the same number of threads as cores. This means the the CPU does not support hyperthreading.
