Intel Core i7-870 vs Intel Core i7-975

Core i7-870 vs Core i7-975 specs and performance

Our benchmark analysis concludes that the Core i7-870 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.

Our spec comparison shows that they have an identical amount of cores and the same number of threads. With our hardware info, we find that the Core i7-975 has a slightly higher clock speed than the Core i7-870. In addition, both chips have the same turbo speed. A Core i7-870 CPU outputs less heat than a Core i7-975 CPU because of its slightly 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 i7-870 has more threads than cores. Each physical core is split into multiple threads.
