Core i7-1255U vs Ryzen 5 7520U specs and performance

In our benchmarks, the Core i7-1255U beats the Ryzen 5 7520U in overall performance. Furthermore, our gaming benchmark shows that it also outperforms the Ryzen 5 7520U in all gaming tests too.

In terms of the number of cores of each of these CPUs, the Core i7-1255U has significantly more cores than the Ryzen 5 7520U. Indeed, the Core i7-1255U has 10 cores compared to 4 cores found in the Ryzen 5 7520U. It also has more threads than the Ryzen 5 7520U. These CPUs have different clock speeds. Indeed, the Ryzen 5 7520U has a significantly higher clock speed compared to the Core i7-1255U. Despite this, the Core i7-1255U has a slightly higher turbo speed. Both these chips have an identical TDP (Thermal Design Power). This measures the amount of heat they output and can be used to estimate power consumption. In terms of cache, the Core i7-1255U has significantly more L2 cache when compared to the Ryzen 5 7520U. The Core i7-1255U also has significantly 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.
