AMD Ryzen 7 3700U vs Intel Core i7-3940XM

Ryzen 7 3700U vs Core i7-3940XM specs and performance

Our benchmark analysis concludes that the Ryzen 7 3700U performs better than the Core i7-3940XM. Furthermore, our gaming benchmark shows that it also outperforms the Core i7-3940XM in all gaming tests too.

When comparing these CPUs we notice that they have the same number of cores and the same number of threads. Our comparison shows that the Core i7-3940XM has a slightly higher clock speed compared to the Ryzen 7 3700U. A Ryzen 7 3700U CPU outputs less heat than a Core i7-3940XM CPU because of its significantly lower TDP. This measures the amount of heat they output and can be used to estimate power consumption. In terms of cache, the Ryzen 7 3700U has significantly more L2 cache when compared to the Core i7-3940XM. Despite this, the Core i7-3940XM has significantly more L3 cache compared to the Ryzen 7 3700U.

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 3700U has more threads than cores. Each physical core is split into multiple threads.
