Core i7-1255U vs Ryzen 5 7640HS benchmarks

According to the hardwareDB Benchmark tool, the Ryzen 5 7640HS is faster than the Core i7-1255U. Despite this, the Core i7-1255U has the advantage in our gaming benchmark.

With info from our database, we find that the Core i7-1255U has significantly more cores with 10 cores whereas the Ryzen 5 7640HS has 6 cores. But they both have the same number of threads. These CPUs have different clock speeds. Indeed, the Ryzen 5 7640HS has a significantly higher clock speed compared to the Core i7-1255U. Also, the Ryzen 5 7640HS has a slightly higher turbo speed. A Core i7-1255U CPU outputs less heat than a Ryzen 5 7640HS CPU because of its 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 Ryzen 5 7640HS has significantly more L2 cache than the Core i7-1255U. The Ryzen 5 7640HS 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 i7-1255U has more threads than cores. Each physical core is split into multiple threads.
