Core i7-7660U vs Core 2 Quad Q9505 benchmarks
Our benchmark analysis concludes that the Core i7-7660U performs better than the Core 2 Quad Q9505. Furthermore, our gaming benchmark shows that it also outperforms the Core 2 Quad Q9505 in all gaming tests too.
When comparing core counts for these CPUs, we notice that the Core 2 Quad Q9505 has significantly more cores with 4 cores compared to the Core i7-7660U that has 2 cores. But they both have the same number of threads. These CPUs have different clock speeds. Indeed, the Core 2 Quad Q9505 has a slightly higher clock speed compared to the Core i7-7660U. A Core i7-7660U CPU outputs less heat than a Core 2 Quad Q9505 CPU because of its significantly lower TDP. This measures the amount of heat they output and can be used to estimate power consumption.
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 i7-7660U has more threads than cores. Each physical core is split into multiple threads.
