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

Core i7-4790 vs Xeon E3-1275 v3 comparison

Our benchmark analysis concludes that the Xeon E3-1275 v3 performs better than the Core i7-4790. Despite this, the Core i7-4790 has the advantage in our gaming benchmark.

When comparing these CPUs we notice that they have the same number of cores and the same number of threads. These CPUs have different clock speeds. Indeed, the Core i7-4790 has a slightly higher clock speed compared to the Xeon E3-1275 v3. Also, the Core i7-4790 has a slightly higher turbo speed. A Core i7-4790 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 i7-4790 has more threads than cores. Each physical core is split into multiple threads.
