Core i7-3770 vs Core i3-1215U comparison
In our benchmarks, the Core i3-1215U beats the Core i7-3770 in overall performance. Furthermore, our gaming benchmark shows that it also outperforms the Core i7-3770 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 i7-3770. Indeed, the Core i3-1215U has 6 cores compared to 4 cores found in the Core i7-3770. But they both have the same number of threads. Our comparison shows that the Core i7-3770 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 i7-3770 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 i7-3770. The Core i3-1215U also has slightly 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. Indeed, the Core i7-3770 has more threads than cores. Each physical core is split into multiple threads.
