Intel Core i7-1260U vs Intel Core Ultra 5 125U

Core i7-1260U vs Core Ultra 5 125U benchmarks

In our benchmarks, the Core Ultra 5 125U beats the Core i7-1260U in overall performance. Despite this, the Core i7-1260U has the advantage in our gaming benchmark.

In terms of the number of cores of each of these CPUs, the Core Ultra 5 125U has slightly more cores than the Core i7-1260U. Indeed, the Core Ultra 5 125U has 12 cores compared to 10 cores found in the Core i7-1260U. It also has more threads than the Core i7-1260U. Our comparison shows that the Core Ultra 5 125U has a significantly higher clock speed compared to the Core i7-1260U. Despite this, the Core i7-1260U has a slightly higher turbo speed. In terms of cache, the Core Ultra 5 125U has significantly more L2 cache when compared to the Core i7-1260U. 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. Indeed, the Core i7-1260U has more threads than cores. Each physical core is split into multiple threads.
