Intel Core i5-8259U vs Intel Core i7-8550U

Core i5-8259U vs Core i7-8550U benchmarks

According to the hardwareDB Benchmark tool, the Core i7-8550U is faster than the Core i5-8259U. Despite this, the Core i5-8259U has the advantage in our gaming benchmark.

Our spec comparison shows that they have an identical amount of cores and the same number of threads. Our comparison shows that the Core i5-8259U has a slightly higher clock speed compared to the Core i7-8550U. Despite this, the Core i7-8550U has a slightly higher turbo speed. The Core i7-8550U outputs less heat than Core i5-8259U thanks to a significantly lower TDP. This measures the amount of heat they output and can be used to estimate power consumption. The data shows that both these CPUs have same sized L2 caches. The Core i7-8550U also has slightly more 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 i5-8259U has more threads than cores. Each physical core is split into multiple threads.
