AMD Ryzen 7 5800U vs Intel Core i7-1255U

Ryzen 7 5800U vs Core i7-1255U specs and performance

According to the hardwareDB Benchmark tool, the Ryzen 7 5800U is faster 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 5800U that has 8 cores. Despite this, the Ryzen 7 5800U has more threads than the Core i7-1255U. Our comparison shows that the Ryzen 7 5800U has a slightly 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, both these CPUs have the same amount of L2 cache. The Ryzen 7 5800U also has slightly more L3 cache.

The more cores a CPU has, the better the overall performance will be in parallel workloads such as multitasking. Many CPUs have more threads than cores, this means that each physical core is split into multiple logical cores, making them more efficient. Indeed, the Ryzen 7 5800U has more threads than cores. Each physical core is split into multiple threads.
