Core i5-5257U vs Pentium G4520 comparison

According to the hardwareDB Benchmark tool, the Core i5-5257U is faster than the Pentium G4520. Despite this, the Pentium G4520 has the advantage in our gaming benchmark.

Our spec comparison shows that they have an identical amount of cores but the Core i5-5257U has more threads. Our comparison shows that the Pentium G4520 has a slightly higher clock speed compared to the Core i5-5257U. A Core i5-5257U CPU outputs less heat than a Pentium G4520 CPU because of its significantly lower TDP. 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 Pentium G4520 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.
