The 7900 XTX looks much more like a current-gen GPU than the massive RTX 4080.

Xbox Series S for scale. The 7900 XTX is smaller than the 4080, but that doesn’t make it tiny.

AMD’s next-generation Radeon RX 7900 XTX and 7900 XT graphics cards will launch next week on December 13. Powered by the chip-based RDNA3 architecture, these $999 and $899 GPUs will rival Nvidia’s $1,200+ RTX 4000 series and attempt to address some of the shortcomings of the outgoing RX 6000 series (performance of mediocre real-time ray tracing, to begin with).
One thing you’ll notice about the cards – and which might appeal to people building in smaller cases – is that the cards are considerably smaller than the current RTX 4080 and 4090 GPUs, and they don’t use the 12VHPWR connector which gave Nvidia some difficulty.

We cannot say anything about whether the cards performance is bigger or smaller than the RTX 4080 until our review is done next week. But in the meantime, we can show you that the 7900 XTX (and the even smaller 7900 XT) are next-gen GPUs that will fit in most of the same cases as current-gen GPUs.
Neither GPU uses a dual-slot fan and heatsink, but they stick to 2.5-slot coolers similar to those used for the 6900 XT series and many partner cards. And power continues to be supplied by a pair of 8-pin sockets, so you don’t need to worry about adapters or running extra wires if your PC is already configured to supply power from this way.

The flagship 7900 XTX measures 11.3 × 4.8 × 2.1 inches (287 × 121.9 × 53.3 mm), and the slightly smaller 7900 XT measures 10.9 × 4.4 × 2, 1 inch (276.9 × 111.8 × 53.3mm). Nvidia’s proprietary RTX 4090 and 4080 designs both measure 12×5.4×2.4 inches (304×137×61mm), and the 12VHPWR adapters that come with them add a little extra width on top of that. The upshot is that the 4080 and 4090 can be tricky to fit into some PC cases, especially next to a large CPU cooler or other components, while the 7900 series should be able to fit into any which enclosure can handle a 6900 or 3090 series. card.
Of course, it doesn’t matter if the Radeon cards are smaller if they can’t keep up with the 4080 or 4090, we’ll be looking at performance, heat, and power efficiency in more detail when our review goes live next week. .
