Intel Core i5-8259U vs Intel Xeon E3-1226 v3

Core i5-8259U vs Xeon E3-1226 v3 comparison

Our benchmark analysis concludes that the Xeon E3-1226 v3 performs better than the Core i5-8259U. Furthermore, our gaming benchmark shows that it also outperforms the Core i5-8259U in all gaming tests too.

When comparing these CPUs we notice that they have the same number of cores but the Core i5-8259U has more threads. With our hardware info, we find that the Xeon E3-1226 v3 has a significantly higher clock speed than the Core i5-8259U. Despite this, the Core i5-8259U has a slightly higher turbo speed. A Core i5-8259U CPU outputs less heat than a Xeon E3-1226 v3 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 i5-8259U has more threads than cores. Each physical core is split into multiple threads.
