AMD recently quietly launched two entry-level graphics cards based on the RDNA 3 architecture - Radeon RX 7400 and Radeon Pro W7400.These two graphics cards are aimed at different markets: the RX 7400 is targeted at entry-level gamers, while the Radeon Pro W7400 is targeted at the professional workstation market.
Both graphics cards use AMD's Navi 33 chip. Navi 33 is the smallest chip in RDNA 3 and has relatively low production costs, so AMD chose to use it for these two entry-level graphics cards.
Previously, Navi 33 has also been used in low-end and mid-range graphics cards such as Radeon RX 7600, RX 7600 XT and RX 7650 GRE.
The RX 7400 has 28 RDNA 3 computing units (CU) and 1,792 stream processors. Compared with the Radeon RX 7600, the number of stream processors is reduced by 12.5%, but the performance gap may not be particularly obvious.
The graphics memory of the two graphics cards is different. The RX 7400 is equipped with a slower 10.8 Gbps GDDR6 graphics memory, while the RX 7600 has a graphics memory speed of 18 Gbps. The RX 7400 supports DisplayPort 2.1 and HDMI 2.1 interfaces, which can meet the needs of most players.
The RX 7400's TBP power consumption is only 55W, so no additional external power supply is required, and a 450W power supply can meet its minimum requirements.
According to the description on AMD's official website, the graphics card adopts a single-slot design and is 6.65 inches (167 mm) long, suitable for most small chassis.
The Pro W7400 is the professional workstation version of the RX 7400. The specifications of the two are almost identical. AMD has not yet announced the prices of these two processors, but considering their positioning, the prices should not be too high.
