Intel Celeron J4105 vs Intel Core i7-4558U

Celeron J4105 vs Core i7-4558U benchmarks

Our benchmark analysis concludes that the Celeron J4105 performs better than the Core i7-4558U. Despite this, the Core i7-4558U has the advantage in our gaming benchmark.

In terms of the number of cores of each of these CPUs, the Celeron J4105 has significantly more cores than the Core i7-4558U. Indeed, the Celeron J4105 has 4 cores compared to 2 cores found in the Core i7-4558U. But they both have the same number of threads. With our hardware info, we find that the Core i7-4558U has a significantly higher clock speed than the Celeron J4105. A Celeron J4105 CPU outputs less heat than a Core i7-4558U 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 J4105 has the same number of threads as cores. This means the the CPU does not support hyperthreading.
