Xeon E3-1281 v3 vs Xeon E3-1505M v6 specs and performance

According to the hardwareDB Benchmark tool, the Xeon E3-1505M v6 is faster than the Xeon E3-1281 v3. Despite this, the Xeon E3-1281 v3 has the advantage in our gaming benchmark.

Our spec comparison shows that they have an identical amount of cores and the same number of threads. These CPUs have different clock speeds. Indeed, the Xeon E3-1281 v3 has a slightly higher clock speed compared to the Xeon E3-1505M v6. Also, the Xeon E3-1281 v3 has a slightly higher turbo speed. The Xeon E3-1505M v6 outputs less heat than Xeon E3-1281 v3 thanks to a significantly 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 E3-1281 v3 has more threads than cores. Each physical core is split into multiple threads.
