Core i7-3820 vs Core 5 120U specs and performance

According to the hardwareDB Benchmark tool, the Core 5 120U is faster than the Core i7-3820. Furthermore, our gaming benchmark shows that it also outperforms the Core i7-3820 in all gaming tests too.

When comparing core counts for these CPUs, we notice that the Core 5 120U has significantly more cores with 10 cores compared to the Core i7-3820 that has 4 cores. It also has more threads than the Core i7-3820. Our comparison shows that the Core i7-3820 has a significantly higher clock speed compared to the Core 5 120U.

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 i7-3820 has more threads than cores. Each physical core is split into multiple threads.
