Ryzen 7 1700X vs Xeon E5-2666 v3 specs and performance

Our benchmark analysis concludes that the Xeon E5-2666 v3 performs better than the Ryzen 7 1700X. Despite this, the Ryzen 7 1700X has the advantage in our gaming benchmark.

When comparing core counts for these CPUs, we notice that the Xeon E5-2666 v3 has slightly more cores with 10 cores compared to the Ryzen 7 1700X that has 8 cores. It also has more threads than the Ryzen 7 1700X. Our comparison shows that the Ryzen 7 1700X has a slightly higher clock speed compared to the Xeon E5-2666 v3. In terms of cache, the Ryzen 7 1700X has significantly more L2 cache when compared to the Xeon E5-2666 v3. Despite this, the Xeon E5-2666 v3 has significantly more L3 cache compared to the Ryzen 7 1700X.

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 Ryzen 7 1700X has more threads than cores. Each physical core is split into multiple threads.
