Core i7-8665U vs Core i5-3570 specs and performance

According to the hardwareDB Benchmark tool, the Core i7-8665U is faster than the Core i5-3570. Furthermore, our gaming benchmark shows that it also outperforms the Core i5-3570 in all gaming tests too.

Info from our database shows that they both have the same core count but the Core i7-8665U has more threads. With our hardware info, we find that the Core i5-3570 has a significantly higher clock speed than the Core i7-8665U. Despite this, the Core i7-8665U has a slightly higher turbo speed. A Core i7-8665U CPU outputs less heat than a Core i5-3570 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 i7-8665U has more threads than cores. Each physical core is split into multiple threads.
