Intel Core i7-5820K vs Intel Core i5-1335U

Core i7-5820K vs Core i5-1335U benchmarks

According to the hardwareDB Benchmark tool, the Core i5-1335U is faster than the Core i7-5820K. Furthermore, our gaming benchmark shows that it also outperforms the Core i7-5820K in all gaming tests too.

When comparing core counts for these CPUs, we notice that the Core i5-1335U has significantly more cores with 10 cores compared to the Core i7-5820K that has 6 cores. But they both have the same number of threads. With our hardware info, we find that the Core i7-5820K has a significantly higher clock speed than the Core i5-1335U. Despite this, the Core i5-1335U has a slightly higher turbo speed.

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 i7-5820K has more threads than cores. Each physical core is split into multiple threads.
