A8-7650K vs Core 2 Quad Q9550 comparison
In our benchmarks, the A8-7650K beats the Core 2 Quad Q9550 in overall performance. Furthermore, our gaming benchmark shows that it also outperforms the Core 2 Quad Q9550 in all gaming tests too.
In terms of the number of cores of each of these CPUs, the Core 2 Quad Q9550 has significantly more cores than the A8-7650K. Indeed, the Core 2 Quad Q9550 has 4 cores compared to 2 cores found in the A8-7650K. But they both have the same number of threads. Our comparison shows that the A8-7650K has a slightly higher clock speed compared to the Core 2 Quad Q9550. A A8-7650K CPU outputs less heat than a Core 2 Quad Q9550 CPU because of its significantly lower TDP. This measures the amount of heat they output and can be used to estimate power consumption. The cache sizes of these CPUs are different. Indeed, the Core 2 Quad Q9550 has significantly more L2 cache than the A8-7650K
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 A8-7650K has more threads than cores. Each physical core is split into multiple threads.
