Intel Xeon E3-1245 v5 vs Intel Xeon X5647

Xeon E3-1245 v5 vs Xeon X5647 benchmarks

Our benchmark analysis concludes that the Xeon X5647 performs better than the Xeon E3-1245 v5. Despite this, the Xeon E3-1245 v5 has the advantage in our gaming benchmark.

When comparing these CPUs we notice that they have the same number of cores and the same number of threads. These CPUs have different clock speeds. Indeed, the Xeon E3-1245 v5 has a slightly higher clock speed compared to the Xeon X5647. Also, the Xeon E3-1245 v5 has a slightly higher turbo speed. A Xeon E3-1245 v5 CPU outputs less heat than a Xeon X5647 CPU because of its significantly lower TDP. This measures the amount of heat they output and can be used to estimate power consumption. The data shows that both these CPUs have same sized L2 caches. The Xeon X5647 also has significantly more L3 cache.

Modern CPUs generally have more logical cores than physical cores, this means that each core is split into multiple virtual cores, improving efficiency for parallel workloads. Indeed, the Xeon E3-1245 v5 has more threads than cores. Each physical core is split into multiple threads.
