r5-2400g boxThe  R5 2400G is AMD’s flagship APU. The 4/8 CPU core layout provides a strong general 64-bit processor and the Vega 11 graphics provide the best integrated graphics blend the industry has seen so far. Intel’s competing Core i5-8400 ($189) and Core i3-8350K ($169) come up short on the graphic front. AMD’s Vega integrated graphics are miles ahead of Intel UHD graphics.

The AMD R4 2400G comes with the popular Wraith Stealth cooler which is effective and runs quietly. The cooler is supplied with a thermal pad but we have a large tube of MX-4 which outperforms the pads.

Thanks to TSMC 14nm process and Raven Ridge architecture, the Ryzen 5 2400G runs at a 0.2GHz faster base clock, and the chip’s boost clock has also been increased by a factor of 0.5GHz compared to its predecessor, the R5 1400 which requires a discrete graphics card. The R5 2400G adds Vega 11 graphics in addition to faster speeds.

Beyond that, AMD promises its new Raven Ridge design also reduces cache and memory latencies, helping the processor to perform faster with all workloads – especially gaming.

Best bet for RAM is to use DDR4-3200 which is the top JEDEC speed. The R5 2400G can operate at DDR4-2933 which the faster memory can afford easily with some room for overclocking. The rival Intel I5-8400 cannot get past DDR4-2400.

2400 Dual 2
2133 Single 4
1866 Dual 4

BIOS updates may allow the processor to handle faster speed memory with 4 DIMMs installed. For the most part the memory controller is hard pressed to handle so many wait states.


The TDP is configurable from 46W to 65W within the BIOS. If you use MX-4 we can recommend the 65W configuration to allow the Vega graphics to be used for lots of gaming.

Vega 11 has 704 streaming processors which is compares to the nVidia GT 1030. The Vega 11 uses up to 2048MB of system memory. We suggest 16GB of memory for the Ryzen 5 2400G so that Windows will be able to use the Vega 11 to best advantage.

The Vega 11 is much more powerful than the R5200R5 300 and R5 400 series graphics cards. It is also more powerful then the R7 200 series.

The infinity fabric is what makes the R5 2400G so powerful. It interconnects all of the various subsystems to maximize on die processes. The DDR4 memory controller is directly connected so fast memory is important for the best performance.

The multimedia engine makes DVD and BD playback easy with hardware support. The4 R5 2400G can handle 3820×2160 full 60 fps with 8-bit or 10-bit HEVC.


We bought this processor for our MSI B350M Bazooka motherboard. Combined with 16GB or more memory this combination is a potent platform for home or business.

It’s wise to use Arctic MX-4 with the Wraith Cooler to prevent thermal throttling. The OEM thermal pad is not adequate for extreme thermal loads imposed by gaming.

The R5 2400G has 8 PCI Express 3.0 lanes for a video card which is quite adequate. PCI Express 3.0 is 4x the performance of the original PCI Express slot. Lanes are needed for the M.2 PCI Express SSD.
