Celeron J4005 vs Core i3-3120M specs and performance

In our benchmarks, the Core i3-3120M beats the Celeron J4005 in overall performance. Furthermore, our gaming benchmark shows that it also outperforms the Celeron J4005 in all gaming tests too.

Info from our database shows that they both have the same core count but the Core i3-3120M has more threads. With our hardware info, we find that the Core i3-3120M has a slightly higher clock speed than the Celeron J4005. A Celeron J4005 CPU outputs less heat than a Core i3-3120M 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 J4005 has the same number of threads as cores. This means the the CPU does not support hyperthreading.
