Intel Core i7-9700K vs Intel Core Ultra 5 135U

Core i7-9700K vs Core Ultra 5 135U comparison

According to the hardwareDB Benchmark tool, the Core Ultra 5 135U is faster than the Core i7-9700K. Despite this, the Core i7-9700K has the advantage in our gaming benchmark.

When comparing core counts for these CPUs, we notice that the Core Ultra 5 135U has significantly more cores with 12 cores compared to the Core i7-9700K that has 8 cores. It also has more threads than the Core i7-9700K. Our comparison shows that the Core i7-9700K has a significantly higher clock speed compared to the Core Ultra 5 135U. Also, the Core i7-9700K has a slightly higher turbo speed. The cache sizes of these CPUs are different. Indeed, the Core Ultra 5 135U has significantly more L2 cache than the Core i7-9700K. 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. For instance, the Core i7-9700K has the same number of threads as cores. This means the the CPU does not support hyperthreading.
