Intel Core i3-8100 vs Intel Core i3-1215U

Core i3-8100 vs Core i3-1215U comparison

Our benchmark analysis concludes that the Core i3-1215U performs better than the Core i3-8100. Furthermore, our gaming benchmark shows that it also outperforms the Core i3-8100 in all gaming tests too.

In terms of the number of cores of each of these CPUs, the Core i3-1215U has significantly more cores than the Core i3-8100. Indeed, the Core i3-1215U has 6 cores compared to 4 cores found in the Core i3-8100. It also has more threads than the Core i3-8100. These CPUs have different clock speeds. Indeed, the Core i3-8100 has a significantly higher clock speed compared to the Core i3-1215U. Despite this, the Core i3-1215U has a slightly higher turbo speed. The Core i3-1215U outputs less heat than Core i3-8100 thanks to a significantly lower TDP. This measures the amount of heat they output and can be used to estimate power consumption. The cache sizes of these CPUs are different. Indeed, the Core i3-1215U has significantly more L2 cache than the Core i3-8100. The Core i3-1215U also has significantly more L3 cache.

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 Core i3-8100 has the same number of threads as cores. This means the the CPU does not support hyperthreading.
