Intel Core i5-8250U vs Intel Core i7-870

Core i5-8250U vs Core i7-870 benchmarks

Our benchmark analysis concludes that the Core i5-8250U performs better than the Core i7-870. Furthermore, our gaming benchmark shows that it also outperforms the Core i7-870 in all gaming tests too.

Our spec comparison shows that they have an identical amount of cores and the same number of threads. These CPUs have different clock speeds. Indeed, the Core i7-870 has a significantly higher clock speed compared to the Core i5-8250U. Also, the Core i7-870 has a slightly higher turbo speed. A Core i5-8250U CPU outputs less heat than a Core i7-870 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 i5-8250U has more threads than cores. Each physical core is split into multiple threads.
