Intel Core 2 Quad Q9400 vs Intel Core i5-6198DU

Core 2 Quad Q9400 vs Core i5-6198DU benchmarks

Our benchmark analysis concludes that the Core i5-6198DU performs better than the Core 2 Quad Q9400. Furthermore, our gaming benchmark shows that it also outperforms the Core 2 Quad Q9400 in all gaming tests too.

When comparing core counts for these CPUs, we notice that the Core 2 Quad Q9400 has significantly more cores with 4 cores compared to the Core i5-6198DU that has 2 cores. But they both have the same number of threads. Our comparison shows that the Core 2 Quad Q9400 has a slightly higher clock speed compared to the Core i5-6198DU. In terms of cache, the Core 2 Quad Q9400 has significantly more L2 cache when compared to the Core i5-6198DU

Modern CPUs generally have more logical cores than physical cores, this means that each core is split into multiple virtual cores, improving efficiency for parallel workloads. For instance, the Core 2 Quad Q9400 has the same number of threads as cores. This means the the CPU does not support hyperthreading.
