Intel Core i7-4790K vs Intel Xeon E3-1275 v3

Core i7-4790K vs Xeon E3-1275 v3 benchmarks

Our benchmark analysis concludes that the Core i7-4790K performs better than the Xeon E3-1275 v3. Furthermore, our gaming benchmark shows that it also outperforms the Xeon E3-1275 v3 in all gaming tests too.

Our spec comparison shows that they have an identical amount of cores and the same number of threads. These CPUs have different clock speeds. Indeed, the Core i7-4790K has a slightly higher clock speed compared to the Xeon E3-1275 v3. Also, the Core i7-4790K has a slightly higher turbo speed. A Core i7-4790K CPU outputs less heat than a Xeon E3-1275 v3 CPU because of its slightly 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 i7-4790K has more threads than cores. Each physical core is split into multiple threads.
