A quick look at AMD’s Radeon RX 7900 XTX, which is smaller than an RTX 4080

AMD’s next-generation Radeon RX 7900 XTX and 7900 XT graphics playing cards launch next week on December 13. Powered by the chiplet-based RDNA3 structure, these $999 and $899 GPUs will compete with Nvidia’s $1,200-and-up RTX 4000-series and can try to deal with a number of the shortcomings of the outgoing RX 6000-series (lackluster real-time raytracing efficiency, for one).

One factor you may discover concerning the playing cards—and one which will please individuals constructing in smaller circumstances—is that the playing cards are significantly smaller than present RTX 4080 and 4090 GPUs, and so they do not use the 12VHPWR connector that has given Nvidia some hassle.

The RX 7900 series still uses 8-pin power connectors, the same as older GPUs.

We will not say something about whether or not the playing cards’ efficiency is bigger or smaller than the RTX 4080’s till our evaluation runs subsequent week. However within the meantime, we will present you that the 7900 XTX (and the even smaller 7900 XT) are next-gen GPUs that can match into many of the identical circumstances as current-gen GPUs.

Neither GPU makes use of a two-slot fan and heatsink, however they do persist with 2.5-slot coolers which are much like those used for the 6900 XT sequence and loads of companion playing cards. And energy continues to be equipped by a pair of 8-pin plugs, so that you needn’t fear about adapters or operating further wires in case your PC is already set as much as present energy this fashion.

The 2.5-slot 7900 series is still thicker than 2-slot cards like the Radeon RX 6800 (top).

The flagship 7900 XTX measures 11.3×4.8×2.1 inches (287×121.9×53.3 mm), and the considerably smaller 7900 XT is 10.9×4.4×2.1 inches (276.9×111.8×53.3 mm). Nvidia’s first-party RTX 4090 and 4080 designs are each 12×5.4×2.4 inches (304×137×61 mm), and the 12VHPWR adapters that include them add a little bit of further width on high of that. The upshot is that the 4080 and 4090 could also be troublesome to slot in some PC circumstances, particularly alongside a big CPU cooler or different parts, whereas the 7900 sequence ought to be capable of slot into any case that may deal with a 6900- or 3090-series card.

After all, it would not matter if the Radeon playing cards are smaller if they cannot sustain with the 4080 or 4090—we’ll be taking a look at efficiency, warmth, and energy effectivity in additional depth when our evaluation goes reside subsequent week.
