Ryzen 5 3450U vs Core i7-3820 specs and performance

Our benchmark analysis concludes that the Core i7-3820 performs better than the Ryzen 5 3450U. Despite this, the Ryzen 5 3450U 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. With our hardware info, we find that the Core i7-3820 has a significantly higher clock speed than the Ryzen 5 3450U. Also, the Core i7-3820 has a slightly higher turbo speed. A Ryzen 5 3450U CPU outputs less heat than a Core i7-3820 CPU because of its significantly lower TDP. This measures the amount of heat they output and can be used to estimate power consumption.

The more cores a CPU has, the better the overall performance will be in parallel workloads such as multitasking. Many CPUs have more threads than cores, this means that each physical core is split into multiple logical cores, making them more efficient. Indeed, the Ryzen 5 3450U has more threads than cores. Each physical core is split into multiple threads.
