Price and rating as shown on Amazon when we collected them. Both change.
The Gigabyte GeForce RTX 5080 GAMING OC 16G takes the top spot in this guide at £1,319.99 — £30.00 above the cheapest card in the group and £444.75 below the dearest. Its headline numbers are the ones every RTX 5080 here shares: 16 GB of GDDR7 on a 256-bit interface, PCIe 5.0, and a 2730 MHz core clock that at least agrees with itself, appearing in both the product title and the spec table. It carries a 4.5 rating from 317 ratings, with 83 of the counted reviews sitting at five stars.
The listing is not free of the field errors that run through this guide. Its memory clock speed is printed as 28000 MHz — 28 Gbps — on a card whose GDDR7 is a 30 Gbps part, the same 30 Gbps figure the other listings here mangle. The box contents field says 'Manual' and nothing else, while a bullet promises a 'versatile VGA holder' and one reviewer reports a support bracket arriving in the box. The star breakdown shown alongside the listing adds up to 100 reviews, not the 317 the same listing reports. Everything on this page is taken from the Amazon listing for this card; we have not tested it ourselves.
