Xeon E3-1245 vs Xeon E5-2440 benchmarks

Our benchmark analysis concludes that the Xeon E3-1245 performs better than the Xeon E5-2440. Furthermore, our gaming benchmark shows that it also outperforms the Xeon E5-2440 in all gaming tests too.

When comparing core counts for these CPUs, we notice that the Xeon E5-2440 has significantly more cores with 6 cores compared to the Xeon E3-1245 that has 4 cores. It also has more threads than the Xeon E3-1245. Our comparison shows that the Xeon E3-1245 has a slightly higher clock speed compared to the Xeon E5-2440. Also, the Xeon E3-1245 has a slightly higher turbo speed. Both these chips have an identical TDP (Thermal Design Power). 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 Xeon E3-1245 has more threads than cores. Each physical core is split into multiple threads.
