Intel Core i7-8700T vs Intel Core i5-1235U

Core i7-8700T vs Core i5-1235U benchmarks

In our benchmarks, the Core i5-1235U beats the Core i7-8700T in overall performance. Furthermore, our gaming benchmark shows that it also outperforms the Core i7-8700T in all gaming tests too.

In terms of the number of cores of each of these CPUs, the Core i5-1235U has significantly more cores than the Core i7-8700T. Indeed, the Core i5-1235U has 10 cores compared to 6 cores found in the Core i7-8700T. But they both have the same number of threads. With our hardware info, we find that the Core i7-8700T has a significantly higher clock speed than the Core i5-1235U. Despite this, the Core i5-1235U has a slightly higher turbo speed. The Core i5-1235U outputs less heat than Core i7-8700T thanks to a significantly lower TDP. This measures the amount of heat they output and can be used to estimate power consumption. The cache sizes of these CPUs are different. Indeed, the Core i5-1235U has significantly more L2 cache than the Core i7-8700T. However, both these chips have the same amount of L3 cache.

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 i7-8700T has more threads than cores. Each physical core is split into multiple threads.
