AMD has introduced two new graphics cards based on the chipmaker’s previous RDNA 3 architecture. The Radeon RX 7400 is an economical gaming graphics card targeting budget-conscious gamers, while the Radeon Pro W7400 caters to the professional and workstation markets.
The Radeon RX 7400 and Radeon Pro W7400 are based on AMD’s Navi 33 (codenamed Hotpink Bonefish) silicon, which is likely the reason why the company decided to roll these out quietly without any fanfare. Navi 33 is also found in other lower-tier SKUs, including the Radeon RX 7600, Radeon RX 7600 XT, and the Radeon RX 7650 GRE. Navi 33, being the smallest silicon inside the RDNA 3 family, should be even cheaper to produce now, so it’s reasonable to reuse it inside the Radeon RX 7400 and Radeon Pro W7400.

The Radeon RX 7400 doesn’t need any external power connectors. The Navi 33-powered graphics card has a TBP (Typical Board Power) of 55W, so a 450W power supply is sufficient as a minimum. AMD hasn’t confirmed whether there will be custom designs, but based on the description, the graphics card listed on AMD’s website adheres to a single-slot design with a length of 6.65 inches (167mm).
Meanwhile, the Radeon Pro W7400 is the workstation variant of the Radeon RX 7400, sharing identical specifications. AMD positions the Radeon Pro W7400 under the existing Radeon Pro W7500. Examining the specifications, the first is essentially a lower-binned version of the second.
Both have the same number of CUs and memory capacity. However, the Radeon Pro W7400 has the same 10.6 Gbps memory as the Radeon RX 7400, resulting in the same bandwidth. It’s 32% lower than the Radeon Pro W7500. The Radeon Pro W7500 was already an energy-efficient workstation graphics card, but the Radeon Pro W7400’s compromises have allowed AMD further to reduce the TBP by 21% on the latter.
The Radeon Pro W7400 features a half-height form factor with a single-slot design, measuring 6.6 inches (168mm) in length. It has the same TBP as the Radeon RX 7400, so no external power connectors are required. As for display outputs, the Radeon Pro W7400 sports four mini DisplayPort 2.1 outputs.
AMD hasn’t revealed the pricing for the Radeon RX 7400 or Radeon Pro W7400. Nonetheless, the Radeon RX 7600 and Radeon Pro W7500 launched at $269 and $429, respectively, so the new Navi 33 offerings should be more affordable.
