Xeon E5-1620 vs Xeon E5-2650 specs and performance
Our benchmark analysis concludes that the Xeon E5-2650 performs better than the Xeon E5-1620. Despite this, the Xeon E5-1620 has the advantage in our gaming benchmark.
In terms of the number of cores of each of these CPUs, the Xeon E5-2650 has significantly more cores than the Xeon E5-1620. Indeed, the Xeon E5-2650 has 8 cores compared to 4 cores found in the Xeon E5-1620. It also has more threads than the Xeon E5-1620. Our comparison shows that the Xeon E5-1620 has a significantly higher clock speed compared to the Xeon E5-2650. Also, the Xeon E5-1620 has a slightly higher turbo speed. The Xeon E5-2650 outputs less heat than Xeon E5-1620 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 E5-1620 has more threads than cores. Each physical core is split into multiple threads.
