Intel Core i7-8650U vs Intel Xeon E5-649

Core i7-8650U vs Xeon E5-649 benchmarks

In our benchmarks, the Xeon E5-649 beats the Core i7-8650U in overall performance. Despite this, the Core i7-8650U has the advantage in our gaming benchmark.

In terms of the number of cores of each of these CPUs, the Xeon E5-649 has significantly more cores than the Core i7-8650U. Indeed, the Xeon E5-649 has 6 cores compared to 4 cores found in the Core i7-8650U. Despite this, the Core i7-8650U has more threads than the Xeon E5-649. These CPUs have different clock speeds. Indeed, the Xeon E5-649 has a slightly higher clock speed compared to the Core i7-8650U. Despite this, the Core i7-8650U has a significantly higher turbo speed. A Core i7-8650U CPU outputs less heat than a Xeon E5-649 CPU because of its significantly lower TDP. This measures the amount of heat they output and can be used to estimate power consumption. In terms of cache, the Xeon E5-649 has significantly more L2 cache when compared to the Core i7-8650U. The Xeon E5-649 also has significantly 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 i7-8650U has more threads than cores. Each physical core is split into multiple threads.
