AMD's new Radeon RX 7000 series based on RDNA 3 (details) will be available as Radeon RX 7900 XTX and 7900 XT on December 13th. ComputerBase has test samples that can be shown today. In order to provide added value, the editors have compared the image to the old reference design and GeForce RTX 4000.

AMD Radeon RX 7900 XTX vs. Radeon RX 7900 XT

Radeon RX 7900 XTX and Radeon RX 7900 XT do not use the same cooling system. In width, however, both coolers do not take anything: 2.5 slots are like Radeon RX 6950 XT, 6900 XT and 6800XT, while Radeon RX 6800 and 6700 XT have used a 2.0 slot design.

The cooler of the XTX is also slightly wider and longer than that of the RX 6000 top models, which, considering the TDP of 355 watts (6900/6800 XT : 300 watts, 6950 XT: 355 watts) is not surprising: A slightly larger cooling system meets a higher or the same TDP.

The cooler of the RX 7900 XT is not quite as wide, although a few millimeters longer than that of the RX 6800, but the jump from 2.0 to 2.5 slots should still make the available cooling surface larger. It should, too, because the TDP of the RX 7900 XT is 300 watts, 50 watts higher than that of the Radeon RX 6800.

In addition to the dimensions, AMD has significantly adjusted the design of the new cooler: the silver face has given way to black and the red frame on the side has a much more subtle accent in the form of painted cooler fins.

Radeon RX 7900 XT(X) vs Radeon RX 4080/4090 FE

Compared Compared to the gigantic cooler that Nvidia is using this year on both the GeForce RTX 4090 and the GeForce RTX 4080, AMD's reference design still looks tiny and can be found in systems in which the use of an RTX 4000 in the two previously available series is not possible think is. It remains to be clarified what effects this has on the volume under load.

The use of the classic 8-pin PCI connector is no surprise, because AMD has long been communicating publicly and recently with a certain smugness. Both the Radeon RX 7900 XTX and the Radeon RX 7900 XT use two of them in order to be able to absorb 300 watts of electrical power in accordance with the specification. Partner cards will also rely on this standard, even if three connections can be expected ex works for variants with a particularly high TDP. With the Nvidia GeForce RTX 4000, all previously published designs rely on the new 12+4-pin 12VHPWR connector.

The Radeon RX 7900 XTX will be available on December 13th with an MSRP of $999 before taxes, the Radeon RX 7900 XT will cost $899. The manufacturer has not yet published an RRP for the euro area.

ComputerBase has Radeon RX 7900 XTX and Radeon RX 7900 Received XT on loan from AMD for testing. The graphics cards were made available under NDA. The embargo on details or even tests has not yet fallen, but the embargo on content that only shows the new reference designs has. The only other specification in this context was the earliest possible publication date. The manufacturer did not exert any influence on the content, there was no obligation to publish it.
