Intel Core i7 Q 720 vs Intel Pentium G645

Core i7 Q 720 vs Pentium G645 specs and performance

In our benchmarks, the Pentium G645 beats the Core i7 Q 720 in overall performance. Furthermore, our gaming benchmark shows that it also outperforms the Core i7 Q 720 in all gaming tests too.

When comparing core counts for these CPUs, we notice that the Core i7 Q 720 has significantly more cores with 4 cores compared to the Pentium G645 that has 2 cores. It also has more threads than the Pentium G645. These CPUs have different clock speeds. Indeed, the Pentium G645 has a significantly higher clock speed compared to the Core i7 Q 720. In terms of cache, the Pentium G645 has significantly more L2 cache when compared to the Core i7 Q 720. Despite this, the Core i7 Q 720 has significantly more L3 cache compared to the Pentium G645.

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 Q 720 has more threads than cores. Each physical core is split into multiple threads.
