Core i7-3820 vs Ryzen 5 7520U specs and performance
In our benchmarks, the Core i7-3820 beats the Ryzen 5 7520U in overall performance. Despite this, the Ryzen 5 7520U 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 Core i7-3820 has a slightly higher clock speed compared to the Ryzen 5 7520U. Despite this, the Ryzen 5 7520U has a slightly higher turbo speed. The Ryzen 5 7520U outputs less heat than Core i7-3820 thanks to a significantly lower TDP. This measures the amount of heat they output and can be used to estimate power consumption.
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 Core i7-3820 has more threads than cores. Each physical core is split into multiple threads.
