Intel Core i5-5257U vs Intel Core i7-6498DU

Core i5-5257U vs Core i7-6498DU specs and performance

Our benchmark analysis concludes that the Core i5-5257U performs better than the Core i7-6498DU. Despite this, the Core i7-6498DU has the advantage in our gaming benchmark.

When comparing these CPUs we notice that they have the same number of cores and the same number of threads. Our comparison shows that the Core i5-5257U has a slightly higher clock speed compared to the Core i7-6498DU. In terms of cache, both these CPUs have the same amount of L2 cache. The Core i7-6498DU 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 i5-5257U has more threads than cores. Each physical core is split into multiple threads.
