Core i5-3470S vs Xeon E5-2420 comparison

Our benchmark analysis concludes that the Xeon E5-2420 performs better than the Core i5-3470S. Despite this, the Core i5-3470S has the advantage in our gaming benchmark.

In terms of the number of cores of each of these CPUs, the Xeon E5-2420 has significantly more cores than the Core i5-3470S. Indeed, the Xeon E5-2420 has 6 cores compared to 4 cores found in the Core i5-3470S. It also has more threads than the Core i5-3470S. Our comparison shows that the Core i5-3470S has a significantly higher clock speed compared to the Xeon E5-2420. Also, the Core i5-3470S has a significantly higher turbo speed. A Core i5-3470S CPU outputs less heat than a Xeon E5-2420 CPU because of its significantly 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. For instance, the Core i5-3470S has the same number of threads as cores. This means the the CPU does not support hyperthreading.
