AMD Phenom II X4 840 vs Intel Pentium Gold 6405U

The AMD Phenom II X4 840 is a 4 core processor with a clock frequency of 3.20 GHz. The processor can compute 4 threads at the same time. The Intel Pentium Gold 6405U clocks with 2.40 GHz, has 2 CPU cores and can calculate 4 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 GB of memory in a maximum of 2 memory channels is supported by the AMD Phenom II X4 840, while the Intel Pentium Gold 6405U supports a maximum of 64 GB of memory with a maximum memory bandwidth of 38.4 GB/s enabled.

The AMD Phenom II X4 840 has a TDP of 95 W. The TDP of the Intel Pentium Gold 6405U is 15 W. System integrators use the TDP of the processor as a guide when dimensioning the cooling solution.

The AMD Phenom II X4 840 has 2.00 MB cache and is manufactured in 45 nm. The cache of Intel Pentium Gold 6405U is at 2.00 MB. The processor is manufactured in 14 nm.
