‘AMD Radeon RX 5900 XT’ emerges: early engineering sample from Big Navi

AMD unveiled the RX 6900 XT, the 6800 XT and the RX 6800 in October. Yet it was already clear that graphics cards based on a larger GPU than Navi 10 had been in the works for some time, as is evident from an early reference to high-end video cards at the European trade commission. Engineering samples must therefore also circulate, and one appears to have turned up at a Chinese reviewer.

On Chiphell, a user named 热心 市民 描边 怪 claims to have bought a “nonexistent graphics card” from Chinese retailer Xianyu. The description already indicates that the card is an ‘RX 5900 XT’, which of course has never been revealed by AMD. It is an engineering sample of what we now know as the RX 6800 XT. He paid 3,500 yuan for it, which is 442 euros. The RX 6800 XT reference model has a suggested retail price of $ 670, and the lower price makes sense when looking at the design of the card.

A sticker shows that it is a sample of the RX 6800 XT Phantom Gaming D OC 16GB. However, the shroud removed, it only concerns the heatsink with the three fans. The backplate has remained, although it is no more than an aluminum-colored heat sink without decorations. It is good to see that the video card has already been through a few things, the cooling fins are bent in several places and the mounting locks are very rusty and are missing two screws. The heat pipes are not nickel-plated and are even oxidized and therefore black in color. Like the final design, there are three 8-pin power connections on display.

However, the reviewer does not compare it with the Phantom Gaming, but with the Taichi X OC version. The seller claimed that the design should be as fast as the final model and even gave the card a three-month warranty. It turns out to be just as fast, but the temperature was a bit warmer at 90 degrees Celsius than that of the RX 6800 XT Taichi, which reached a temperature of 81 degrees Celsius. Consumption was identical with 288 watts.

Above: the GPU temperature, presumably in FurMark. Below: the power consumption in FurMark.
