Core i7-975 vs Xeon E5-1603 v3 comparison

Our benchmark analysis concludes that the Core i7-975 performs better than the Xeon E5-1603 v3. Despite this, the Xeon E5-1603 v3 has the advantage in our gaming benchmark.

Info from our database shows that they both have the same core count but the Core i7-975 has more threads. A Core i7-975 CPU outputs less heat than a Xeon E5-1603 v3 CPU because of its slightly lower TDP. This measures the amount of heat they output and can be used to estimate power consumption.

The more cores a CPU has, the better the overall performance will be in parallel workloads such as multitasking. Many CPUs have more threads than cores, this means that each physical core is split into multiple logical cores, making them more efficient. Indeed, the Core i7-975 has more threads than cores. Each physical core is split into multiple threads.
