While we were sent a couple of partner cards for review, today we are only assessing the AMD RX 7900 GRE reference card, which was kindly supplied to us by PCSpecialist.

The design of this model is very similar to the RX 7900 XT, with its matte black metal shroud and triple-fan layout. It's not the same exact card, with the GRE being a bit smaller, but it's very much part of the family. We also get a triple-fan cooler, where each fan measures 80mm in diameter.

In terms of dimensions, the 7900 GRE measures in at approximately 268 x 110 x 50mm, so it's about 2.5 slots thick but relatively compact as modern cards go. It weighed in at 1140g on my scales.

The front side of the card is left fairly bare, with the aluminium finstack occupying most of the space. We also find a full-length metal backplate, with the Radeon branding printed in grey text towards the I/O bracket.

Power is delivered by two PCIe 8-pin connectors, while we also get the usual array of display outputs – 2x DisplayPort 2.1, 1x HDMI 2.1 and 1x USB-C.
