AMD Radeon RX 6400
AMD's entry-level RDNA 2 card, launched to retail in April 2022: 768 stream processors, 4GB of GDDR6 on a 64-bit bus, and just 53W of typical board power drawn entirely from the PCIe slot. At $159 it targets office and media PCs with light 1080p gaming rather than serious performance.
Pros
- 53W typical board power runs entirely off the PCIe slot, no power connector needed
- Low-profile-friendly single-fan cooler suits small-form-factor and HTPC builds
- 16MB of Infinity Cache and 16Gbps memory help offset the narrow 64-bit bus
- Official $159 launch price undercuts most basic office-PC graphics cards
Cons
- 4GB of VRAM and a 64-bit bus restrict it to light 1080p gaming
- PCIe 4.0 x4 host interface loses noticeable performance when run in an older PCIe 3.0 motherboards
- No hardware H.264/HEVC video encode and no AV1 decode support
- Ray accelerator hardware is present but too weak for practical ray-traced gaming
