AMD Athlon II X3 405e or Intel Xeon D-2779 - which processor is faster? In this comparison we look at the differences and analyze which of these two CPUs is better. We compare the technical data and benchmark results.

The AMD Athlon II X3 405e has 3 cores with 3 threads and clocks with a maximum frequency of 2.30 GHz. Up to 16 GB of memory is supported in 2 memory channels. The AMD Athlon II X3 405e was released in Q3/2009.

The Intel Xeon D-2779 has 16 cores with 32 threads and clocks with a maximum frequency of 3.40 GHz. The CPU supports up to 1024 GB of memory in 4 memory channels. The Intel Xeon D-2779 was released in Q1/2022.

The AMD Athlon II X3 405e has 3 CPU cores and can calculate 3 threads in parallel. The clock frequency of the AMD Athlon II X3 405e is 2.30 GHz while the Intel Xeon D-2779 has 16 CPU cores and 32 threads can calculate simultaneously. The clock frequency of the Intel Xeon D-2779 is at 2.50 GHz (3.40 GHz).

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.

The AMD Athlon II X3 405e or Intel Xeon D-2779 has integrated graphics, called iGPU for short. The iGPU uses the system's main memory as graphics memory and sits on the processor's die.

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.

The AMD Athlon II X3 405e can use up to 16 GB of memory in 2 memory channels. The maximum memory bandwidth is 21.3 GB/s. The Intel Xeon D-2779 supports up to 1024 GB of memory in 4 memory channels and achieves a memory bandwidth of up to 102.4 GB/s.

The thermal design power (TDP for short) of the AMD Athlon II X3 405e is 45 W, while the Intel Xeon D-2779 has a TDP of 126 W. The TDP specifies the necessary cooling solution that is required to cool the processor sufficiently.

The AMD Athlon II X3 405e is manufactured in 45 nm and has 1.50 MB cache. The Intel Xeon D-2779 is manufactured in 10 nm and has a 25.00 MB cache.
