Celeron J3455 vs Pentium E5400 specs and performance
Our benchmark analysis concludes that the Celeron J3455 performs better than the Pentium E5400. Despite this, the Pentium E5400 has the advantage in our gaming benchmark.
In terms of the number of cores of each of these CPUs, the Celeron J3455 has significantly more cores than the Pentium E5400. Indeed, the Celeron J3455 has 4 cores compared to 2 cores found in the Pentium E5400. It also has more threads than the Pentium E5400. These CPUs have different clock speeds. Indeed, the Pentium E5400 has a significantly higher clock speed compared to the Celeron J3455. A Celeron J3455 CPU outputs less heat than a Pentium E5400 CPU because of its significantly lower TDP. This measures the amount of heat they output and can be used to estimate power consumption.
Most CPUs have more threads than cores. This technology, colloquially called hyperthreading, improves performance by splitting a core into multiple virtual ones. This provides more efficient utilisation of a core. For instance, the Celeron J3455 has the same number of threads as cores. This means the the CPU does not support hyperthreading.
