Intel Core i5-6400T vs Intel Core i3-2120

Core i5-6400T vs Core i3-2120 specs and performance

Our benchmark analysis concludes that the Core i5-6400T performs better than the Core i3-2120. Despite this, the Core i3-2120 has the advantage in our gaming benchmark.

When comparing core counts for these CPUs, we notice that the Core i5-6400T has significantly more cores with 4 cores compared to the Core i3-2120 that has 2 cores. But they both have the same number of threads. With our hardware info, we find that the Core i3-2120 has a significantly higher clock speed than the Core i5-6400T. A Core i5-6400T CPU outputs less heat than a Core i3-2120 CPU because of its significantly lower TDP. This measures the amount of heat they output and can be used to estimate power consumption.

Modern CPUs generally have more logical cores than physical cores, this means that each core is split into multiple virtual cores, improving efficiency for parallel workloads. For instance, the Core i5-6400T has the same number of threads as cores. This means the the CPU does not support hyperthreading.
