AMD Athlon II X4 651K vs AMD Athlon II X3 455

The AMD Athlon II X4 651K is a 4 core processor with a clock frequency of 3.00 GHz. The processor can compute 4 threads at the same time. The AMD Athlon II X3 455 clocks with 3.30 GHz, has 3 CPU cores and can calculate 3 threads in parallel.

Processors with the support of artificial intelligence (AI) and machine learning (ML) can process many calculations, especially audio, image and video processing, much faster than classic processors. Algorithms for ML improve their performance the more data they have collected via software. ML tasks can be processed up to 10,000 times faster than with a classic processor.

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 651K, while the AMD Athlon II X3 455 supports a maximum of 16 GB of memory with a maximum memory bandwidth of 21.3 GB/s enabled.

The AMD Athlon II X4 651K has a TDP of 100 W. The TDP of the AMD Athlon II X3 455 is 95 W. System integrators use the TDP of the processor as a guide when dimensioning the cooling solution.

The AMD Athlon II X4 651K has 4.00 MB cache and is manufactured in 32 nm. The cache of AMD Athlon II X3 455 is at 1.50 MB. The processor is manufactured in 45 nm.
