Core i7-4510U vs Core 2 Quad Q9400 specs and performance
In our benchmarks, the Core 2 Quad Q9400 beats the Core i7-4510U in overall performance. Furthermore, our gaming benchmark shows that it also outperforms the Core i7-4510U in all gaming tests too.
With info from our database, we find that the Core 2 Quad Q9400 has significantly more cores with 4 cores whereas the Core i7-4510U has 2 cores. But they both have the same number of threads. These CPUs have different clock speeds. Indeed, the Core 2 Quad Q9400 has a slightly higher clock speed compared to the Core i7-4510U. A Core i7-4510U CPU outputs less heat than a Core 2 Quad Q9400 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 i7-4510U has more threads than cores. Each physical core is split into multiple threads.
