Intel Xeon W3580 vs Intel Xeon E5-520

Xeon W3580 vs Xeon E5-520 specs and performance

Our benchmark analysis concludes that the Xeon E5-520 performs better than the Xeon W3580. Despite this, the Xeon W3580 has the advantage in our gaming benchmark.

Info from our database shows that they both have the same core count but the Xeon W3580 has more threads. These CPUs have different clock speeds. Indeed, the Xeon W3580 has a significantly higher clock speed compared to the Xeon E5-520. Also, the Xeon W3580 has a slightly higher turbo speed. The Xeon E5-520 outputs less heat than Xeon W3580 thanks to a significantly lower TDP. This measures the amount of heat they output and can be used to estimate power consumption. The data shows that both these CPUs have same sized L2 caches and 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 Xeon W3580 has more threads than cores. Each physical core is split into multiple threads.
