Intel Xeon X5647 vs Intel Xeon X5670

Xeon X5647 vs Xeon X5670 specs and performance

In our benchmarks, the Xeon X5647 beats the Xeon X5670 in overall performance. Despite this, the Xeon X5670 has the advantage in our gaming benchmark.

In terms of the number of cores of each of these CPUs, the Xeon X5670 has significantly more cores than the Xeon X5647. Indeed, the Xeon X5670 has 6 cores compared to 4 cores found in the Xeon X5647. It also has more threads than the Xeon X5647. Our comparison shows that the Xeon X5670 has a slightly higher clock speed compared to the Xeon X5647. Also, the Xeon X5670 has a slightly higher turbo speed. The Xeon X5670 outputs less heat than Xeon X5647 thanks to a slightly lower TDP. This measures the amount of heat they output and can be used to estimate power consumption. The cache sizes of these CPUs are different. Indeed, the Xeon X5670 has significantly more L2 cache than the Xeon X5647. However, both these chips have the same amount of L3 cache.

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 X5647 has more threads than cores. Each physical core is split into multiple threads.
