Intel Core i5-3470 vs Intel Core i7-975

Core i5-3470 vs Core i7-975 comparison

Our benchmark analysis concludes that the Core i5-3470 performs better than the Core i7-975. Furthermore, our gaming benchmark shows that it also outperforms the Core i7-975 in all gaming tests too.

When comparing these CPUs we notice that they have the same number of cores but the Core i7-975 has more threads. These CPUs have different clock speeds. Indeed, the Core i7-975 has a slightly higher clock speed compared to the Core i5-3470. Furthermore, both these CPUs have identical turbo speeds. A Core i5-3470 CPU outputs less heat than a Core i7-975 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. For instance, the Core i5-3470 has the same number of threads as cores. This means the the CPU does not support hyperthreading.
