We can better compare what are the technical differences between the two processors.
Suggested PSU: We assume that we have An ATX computer case, a high end graphics card, 16GB RAM, a 512GB SSD, a 1TB HDD hard drive, a Blu-Ray drive. We will have to rely on a more powerful power supply if we want to have several graphics cards, several monitors, more memory, etc.
Price: For technical reasons, we cannot currently display a price less than 24 hours, or a real-time price. This is why we prefer for the moment not to show a price. You should refer to the respective online stores for the latest price, as well as availability.
The processor AMD Phenom II X4 945 has a larger number of cores, the maximum frequency of AMD A9-9420 is greater, that the PDT of AMD A9-9420 is lower. The AMD A9-9420 was designed earlier.
Performances :
Performance comparison between the two processors, for this we consider the results generated on benchmark software such as Geekbench 4.

Cinebench R15 evaluates the performance of CPU calculations by restoring a photorealistic 3D scene. The scene has 2,000 objects, 300,000 polygons, uses sharp and fuzzy reflections, bright areas, shadows, procedural shaders, antialiasing, and so on. The faster the rendering of the scene is created, the more powerful the PC is, with a high number of points.
