AMD Radeon RX 6400 Launched at $159


AMD formally launched the entry-level Radeon RX 6400 graphics card. At an MSRP of $159, this is the most affordable graphics card from the Radeon RX 6000 series. It is based on the same RDNA2 graphics architecture as the rest of the RX 6000 lineup, and the smallest silicon of them all, the “Navi 23.” This chip is built on the TSMC N6 (6 nm) silicon fabrication process.

The RX 6400 shares the “Navi 23” silicon with the RX 6500 XT launched earlier this year. AMD enabled 12 out of 16 RDNA2 compute units on the silicon, resulting in 768 stream processors, 48 TMUs, 12 Ray Accelerators, and 32 ROPs. The memory configuration is similar to the RX 6500 XT, with 4 GB of GDDR6 memory across a 64-bit wide memory bus. This is the same 16 Gbps-rated memory, which means 128 GB/s bandwidth on tap. There’s also 16 MB of Infinity Cache. The engine clocks (GPU clocks) are set at 2039 MHz (game) and 2321 MHz (boost). With its given specs, the RX 6400 has a typical graphics power (TGP) of just 53 W, and so cards can do without any power connectors.
