AMD Athlon II X4 620e vs AMD Ryzen 3 5425C

In this CPU comparison, we compare the AMD Athlon II X4 620e and the AMD Ryzen 3 5425C and use benchmarks to check which processor is faster.

We compare the AMD Athlon II X4 620e 4 core processor released in Q2/2011 with the AMD Ryzen 3 5425C which has 4 CPU cores and was introduced in Q3/2022.

The AMD Athlon II X4 620e is a 4 core processor with a clock frequency of 2.60 GHz. The processor can compute 4 threads at the same time. The AMD Ryzen 3 5425C clocks with 2.70 GHz (4.10 GHz), has 4 CPU cores and can calculate 8 threads in parallel.

The performance values of the processor's AI unit. The isolated NPU performance is specified here, the total AI performance (NPU+CPU+iGPU) can be higher. Processors with support for artificial intelligence (AI) and machine learning (ML) can process many calculations, especially audio, image and video processing, much faster than classic processors.

Graphics (iGPU) integrated into the processor not only enable image output without having to rely on a dedicated graphics solution, but can also efficiently accelerate video playback.

A photo or video codec that is accelerated in hardware can greatly accelerate the working speed of a processor and extend the battery life of notebooks or smartphones when playing videos.

Up to 16 GB of memory in a maximum of 2 memory channels is supported by the AMD Athlon II X4 620e, while the AMD Ryzen 3 5425C supports a maximum of 64 GB of memory with a maximum memory bandwidth of 51.2 GB/s enabled.

The AMD Athlon II X4 620e has a TDP of 45 W. The TDP of the AMD Ryzen 3 5425C is 15 W. System integrators use the TDP of the processor as a guide when dimensioning the cooling solution.

The AMD Athlon II X4 620e has 2.00 MB cache and is manufactured in 45 nm. The cache of AMD Ryzen 3 5425C is at 10.00 MB. The processor is manufactured in 7 nm.
