Xeon E3-1281 v3 vs Xeon E3-1245 v5 specs and performance

Our benchmark analysis concludes that the Xeon E3-1245 v5 performs better than the Xeon E3-1281 v3. Furthermore, our gaming benchmark shows that it also outperforms the Xeon E3-1281 v3 in all gaming tests too.

Info from our database shows that they both have the same core count and the same number of threads. With our hardware info, we find that the Xeon E3-1281 v3 has a slightly higher clock speed than the Xeon E3-1245 v5. Also, the Xeon E3-1281 v3 has a slightly higher turbo speed. The Xeon E3-1245 v5 outputs less heat than Xeon E3-1281 v3 thanks to a 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 Xeon E3-1281 v3 has more threads than cores. Each physical core is split into multiple threads.
