Xeon E-2146G vs Xeon E5-2640 v3 benchmarks

Our benchmark analysis concludes that the Xeon E5-2640 v3 performs better than the Xeon E-2146G. Despite this, the Xeon E-2146G has the advantage in our gaming benchmark.

In terms of the number of cores of each of these CPUs, the Xeon E5-2640 v3 has slightly more cores than the Xeon E-2146G. Indeed, the Xeon E5-2640 v3 has 8 cores compared to 6 cores found in the Xeon E-2146G. It also has more threads than the Xeon E-2146G. With our hardware info, we find that the Xeon E-2146G has a slightly higher clock speed than the Xeon E5-2640 v3. Also, the Xeon E-2146G has a slightly higher turbo speed. A Xeon E-2146G CPU outputs less heat than a Xeon E5-2640 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. Indeed, the Xeon E-2146G has more threads than cores. Each physical core is split into multiple threads.
