Core i7-8700K vs Core i5-1335U specs and performance
Our benchmark analysis concludes that the Core i7-8700K performs better than the Core i5-1335U. Despite this, the Core i5-1335U has the advantage in our gaming benchmark.
In terms of the number of cores of each of these CPUs, the Core i5-1335U has significantly more cores than the Core i7-8700K. Indeed, the Core i5-1335U has 10 cores compared to 6 cores found in the Core i7-8700K. But they both have the same number of threads. These CPUs have different clock speeds. Indeed, the Core i7-8700K has a significantly higher clock speed compared to the Core i5-1335U. Also, the Core i7-8700K has a slightly higher turbo speed. The cache sizes of these CPUs are different. Indeed, the Core i5-1335U has significantly more L2 cache than the Core i7-8700K. However, both these chips have the same amount of 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 i7-8700K has more threads than cores. Each physical core is split into multiple threads.
