AMD Radeon RX 6400: specs and benchmarks
- Interface PCIe 4.0 x4
- Core clock speed
- Max video memory 4 GB
- Memory type GDDR6
- Memory clock speed 16 Gbps
- Maximum resolution
AMD started Radeon RX 6400 sales 19 January 2022 at a recommended price of $159. This is a desktop graphics card based on a RDNA 2.0 architecture and made with 6 nm manufacturing process. It is primarily aimed at gamer market. 4 GB of GDDR6 memory clocked at 16 GB/s are supplied, and together with 64 Bit memory interface this creates a bandwidth of 128.0 GB/s.
Compatibility-wise, this is single-slot card attached via PCIe 4.0 x4 interface. No additional power connector is required, and power consumption is at 53 Watt.
It provides poor gaming and benchmark performance at
of a leader's which is NVIDIA GeForce RTX 4090.
