AMD Ryzen 5 2400G vs Intel Core i5-6400 vs Intel Core i5-6600K

AMD Ryzen 5 2400G

► remove from comparison AMD R5 2400G

The AMD Ryzen 5 2400G is a desktop APU that was announced in early 2018. It is the fastest Raven Ridge APU at that time and features all four Zen cores (8 threads due to SMT support) clocked at 3.6 - 3.9 GHz with a Radeon RX Vega 11 graphics card with 11 CUs (all of the 704 Shaders on the chip) clocked at up to 1250 MHz. The integrated dual-channel memory controller supports up to DDR-2933. The TDP is specified at 65 Watt and the CPU, GPU and memory are unlocked for overclocking. More information on Raven Ridge can be found in our launch article.

Intel Core i5-6400

► remove from comparison

The Intel Core i5-6400 is a desktop class quad-core CPU. The additional 4 threads are not available to the CPU as it is missing the HyperThreading support. The i5-6400 is based on Skylake architecture and clocks within the 2.7 GHz to 3.3 GHz range. 

Intel Core i5-6600K

► remove from comparison Intel 6600K

The Intel Core i5-6600K is a high-end quad-core desktop processor based on the Skylake architecture, which was announced in August 2015. The CPU, which is manufactured in a 14 nm process, runs at 3.5 up to 3.9 GHz (2 cores: 3.8 GHz, 3 cores: 3.7 GHz, 4 cores: 3.6 GHz) and – contrary to the i7-series – does not support Hyperthreading. Being a so called "K"-model, the Core i5-6600K has a free multiplier and can be easily overclocked. 

Performance

Because of the slightly slower clocks, the smaller L3-cache (6 instead of 8 MB) as well as the missing Hyperthreading support, the Core i5-6600K is about 10-30 percent slower than the top model i7-6700K. The CPU will still handle demanding applications and games without any problems.

Graphics

Graphics are handled by the integrated Intel HD Graphics 530 with 24 EUs (Execution Units), which is clocked at 350 - 1150 MHz. Compared to the HD Graphics 4600 (Haswell, 20 EUs), the performance is increased by around 25 percent. The overall GPU performance is still low-end, so modern games can, if at all, only be played smoothly with low settings. 

Power Consumption

The TDP was slightly raised from 88 to 91 Watts compared to the predecessor.
