The Radeon RX 7000 series is a series of graphics processing units developed by AMD, based on their RDNA 3 architecture. It was announced on November 3, 2022 [1] and is the successor to the Radeon RX 6000 series. Currently AMD has announced and released seven graphics cards of the Radeon RX 7000 series: RX 7600, RX 7600 XT, RX 7700 XT, RX 7800 XT, RX 7900 GRE, RX 7900 XT, and RX 7900 XTX. [2] AMD officially launched the RX 7900 XT and RX 7900 XTX on December 13, 2022. [3] AMD released the RX 7600 on May 25, 2023. AMD released their last two models of the RDNA 3 family on September 6, 2023; the 7700 XT and the 7800 XT. As of January 2024, AMD have also released the RX 7600 XT and the RX 7900 GRE.

The Navi 31 multi-chip module features 58 billion transistors, a 165% increase in transistor density than the previous generation Navi 2x, across seven dies: one Graphics Compute Die (GCD) and six Memory Cache Dies (MCD). The full Navi 31 die contains 12,288 FP32 cores, equivalent to 6144 stream processors. [8] Reportedly, the Navi 31 die has been designed to scale up to 3.0 GHz frequency, though AMD's Radeon RX 7900 XTX reference design can hit a boost frequency of 2.5 GHz. [9] The Navi 31 die is fabricated on TSMC's N5 process node.

The Navi 33 die features 13.3 billion transistors and a die size of 204 mm2. The full die features 4096 FP32 cores, segmented into 32 Compute Units. [10] Unlike the higher-end Navi 31 die, it is a monolithic design fabricated on TSMC's N6 process node. One of the standout features of the Navi 33 die is its staggering 13.3 billion transistors. Transistors are fundamental in determining the computational power of a chip, and with such a high count, it indicates the capability of the die to handle intricate processing tasks. Furthermore, the die size of 204 mm2 ensures that this vast number of transistors is efficiently packed, providing a balance between power and size. [11]

Issues

Idle power usage

Abnormally high power draw while at idle was observed with the Radeon RX 7900 XT and RX 7900 XTX when using select high resolution, high refresh rate displays and when the GPU is decoding video. ComputerBase discovered that the RX 7900 XT and RX 7900 XTX drew a respective 71W and 80W when decoding and playing a 4K 60FPS YouTube video compared to the 30W used by the RX 6900 XT for the same task. [26] AMD acknowledged the issue and it was added to the list of known issues to be addressed with future updates to drivers and Radeon Adrenalin software. [27] On December 22, 2022, Adrenalin Edition 22.12.2 was released and its RDNA 3-exclusive driver significantly reduced the GPU's power usage at idle and when decoding video. [28] [29]

Reference card temperature issues

AMD's reference editions of the Radeon RX 7900 XT and RX 7900 XTX have suffered from high temperatures of up to 109°C on the GPU hot spot. AIB partner cards were confirmed to not be affected by this issue. The loud fans and thermal throttling on reference cards could have been as a result of poor contact between the reference cooler and the GPU chiplets. [30] HardwareLuxx instead considered that the direct die cooling used for the Navi 31 chiplets could be difficult due to uneven contact pressure across the seven dies even if they may look to be level. [31] AMD issued a statement in December 2022 that it was investigating the issue. [32] AMD said that the noisy fans and thermal throttling on reference cards were due to a manufacturing defect where there was an insufficient amount of water in vapor chambers. [33] [34] Affected cards would be replaced by AMD upon request.

On January 6, 2023, Scott Herkelman, Senior Vice President & General Manager Graphics at AMD, said in an interview with PCWorld that "you would see a small performance delta" if the GPU throttles at 110 °C during certain workloads. [35] Some media outlets disagreed with statements made by Herkelman, such as how he said there was "a small performance delta" when 3 out of 4 affected RX 7900 XTX performed worse than a previous generation 6900 XT in the same test. [36] Usually, the RX 7900 XTX performs approximately 30–60% better than a 6900 XT. [37]
