Intel Xeon E3-1245 v5 vs Intel Xeon X5670

Xeon E3-1245 v5 vs Xeon X5670 comparison

In our benchmarks, the Xeon X5670 beats the Xeon E3-1245 v5 in overall performance. Despite this, the Xeon E3-1245 v5 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 E3-1245 v5. Indeed, the Xeon X5670 has 6 cores compared to 4 cores found in the Xeon E3-1245 v5. It also has more threads than the Xeon E3-1245 v5. Our comparison shows that the Xeon E3-1245 v5 has a slightly higher clock speed compared to the Xeon X5670. Also, the Xeon E3-1245 v5 has a slightly higher turbo speed. A Xeon E3-1245 v5 CPU outputs less heat than a Xeon X5670 CPU because of its 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 E3-1245 v5. The Xeon X5670 also has significantly more 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 E3-1245 v5 has more threads than cores. Each physical core is split into multiple threads.
