The RDNA 3 generation of graphics cards has not said its last word, with a model geared towards small budgets and low-power solutions.
At NVIDIA, when a new range of GPUs and graphics cards is launched, it doesn't take long for the previous generation to bow out... or even be consigned to the closet before the new products are launched! It's a very different story at AMD, which doesn't hesitate to make previous generations last even as new architectures are released. Today, AMD is focusing on GPUs and graphics cards in RDNA 4 architecture - with the launch of the Radeon RX 9070 and Radeon RX 9070 XT - but the previous generation still has some reserve.

With the launch of a new PC by Dell, our colleagues at WCCFTech noticed the existence of a new RDNA 3 graphics card, the Radeon RX 7400. Of course, there's no question of upsetting the current hierarchy or pleasing fans of the most demanding video games. However, this Radeon RX 7400 is not without interest. It's powered by a NAVI 33 GPU - like its big sister, the Radeon RX 7600 - albeit in a smaller version. It features 28 compute units (vs. 32 on the Radeon RX 7600), 28 ray gas pedals (vs. 32), 56 AI gas pedals (vs. 64) and 112 texture units (vs. 128). The Radeon RX 7400 still features 8 GB GDDR6 on a 128-bit interface bus, but bandwidth is considerably lower (173 GB/s vs. 288 GB/s), as slower memory chips (10.8 Gbps vs. 18 Gbps) are used.
What's the point of a less powerful card than the Radeon RX 7600, which has already been overtaken by the new "9000" models? The answer is twofold. Firstly, the GPU and graphics card are obviously less expensive, perfect for more affordable machines. Then there's the greatly reduced power consumption: AMD quotes a TDP of just 55 watts, which is more economical, more ecological and more practical, since the PCI Express port is all that's needed to power the card. It now remains to be seen whether AMD will reserve this card for its integrator partners, or whether it plans to distribute it at retail level.
