Intel Core i7-8665U vs Intel Pentium Gold G6405

Core i7-8665U vs Pentium Gold G6405 benchmarks

Our benchmark analysis concludes that the Core i7-8665U performs better than the Pentium Gold G6405. Furthermore, our gaming benchmark shows that it also outperforms the Pentium Gold G6405 in all gaming tests too.

In terms of the number of cores of each of these CPUs, the Core i7-8665U has significantly more cores than the Pentium Gold G6405. Indeed, the Core i7-8665U has 4 cores compared to 2 cores found in the Pentium Gold G6405. It also has more threads than the Pentium Gold G6405. With our hardware info, we find that the Pentium Gold G6405 has a significantly higher clock speed than the Core i7-8665U. A Core i7-8665U CPU outputs less heat than a Pentium Gold G6405 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.
