Xeon E3-1226 v3 vs Xeon E5-2650 v3 comparison

In our benchmarks, the Xeon E5-2650 v3 beats the Xeon E3-1226 v3 in overall performance. Furthermore, our gaming benchmark shows that it also outperforms the Xeon E3-1226 v3 in all gaming tests too.

With info from our database, we find that the Xeon E5-2650 v3 has significantly more cores with 10 cores whereas the Xeon E3-1226 v3 has 4 cores. It also has more threads than the Xeon E3-1226 v3. With our hardware info, we find that the Xeon E3-1226 v3 has a significantly higher clock speed than the Xeon E5-2650 v3. Also, the Xeon E3-1226 v3 has a slightly higher turbo speed. A Xeon E3-1226 v3 CPU outputs less heat than a Xeon E5-2650 v3 CPU because of its slightly lower TDP. This measures the amount of heat they output and can be used to estimate power consumption.

The more cores a CPU has, the better the overall performance will be in parallel workloads such as multitasking. Many CPUs have more threads than cores, this means that each physical core is split into multiple logical cores, making them more efficient. For instance, the Xeon E3-1226 v3 has the same number of threads as cores. This means the the CPU does not support hyperthreading.
