Core i7-1255U vs Ryzen 7 5825U comparison
Our benchmark analysis concludes that the Ryzen 7 5825U performs better than the Core i7-1255U. Furthermore, our gaming benchmark shows that it also outperforms the Core i7-1255U in all gaming tests too.
When comparing core counts for these CPUs, we notice that the Core i7-1255U has slightly more cores with 10 cores compared to the Ryzen 7 5825U that has 8 cores. Despite this, the Ryzen 7 5825U has more threads than the Core i7-1255U. With our hardware info, we find that the Ryzen 7 5825U has a slightly higher clock speed than 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. When comparing cache sizes, these CPUs have an identical amount of L2 cache. The Ryzen 7 5825U 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.
