Introduction:
The AMD Radeon RX 7900 XT and XTX are powerful graphics cards that offer impressive gaming performance at an affordable price. Priced at $899 and $999 respectively, these GPUs deliver outstanding performance, surpassing Nvidia's RTX 4080 in many games while being $200 cheaper. However, they fall behind in ray-tracing performance compared to Nvidia. In this review, we will explore the hardware, benchmarks, and overall value of the Radeon RX 7900 XT/XTX.
Hardware:
The Radeon RX 7900 XT/XTX is based on AMD's latest RDNA 3 architecture and chiplet technology. This unique design uses multiple dies connected by a fast interconnect, similar to AMD's Ryzen and EPYC CPUs. The 5nm process technology for the graphics compute die and 6nm process for GDDR6 memory ensure efficient performance. The total board power ranges from 315 watts for the RX 7900 XT to 355 watts for the XTX, with recommended power supplies of 750-800 watts.
Performance:
In benchmark tests at 1440p resolution, the Radeon RX 7900 XT/XTX delivers impressive performance, outperforming the RTX 4080 in most games. However, when it comes to ray tracing and upscaling, the AMD cards fall behind Nvidia's DLSS technology. The lack of game support for AMD's FidelityFX Super Resolution (FSR) also limits its upscaling capabilities.
At 4K resolution, the Radeon RX 7900 XTX performs exceptionally well, comfortably outperforming the RX 7900 XT and even matching or surpassing the RTX 4080 in various games. However, when ray tracing and upscaling are enabled, the performance gap widens, with Nvidia's DLSS providing significantly better results.
Software and Cooling:
AMD's software improvements are impressive, with an easy-to-use overlay and settings interface. However, Nvidia still needs to consolidate settings into a single location.
In terms of thermals and noise, the Radeon RX 7900 XTX runs hot, with temperatures nearing 100 degrees Celsius during demanding games. The triple-fan cooling solution generates noticeable fan noise, and there may be coil whine in high frame rate games. Nvidia's cooling solution offers better performance, but it comes with a larger physical size.

Conclusion:
The AMD Radeon RX 7900 XT/XTX graphics cards offer remarkable performance at an affordable price. With excellent rasterization performance and fantastic 4K gaming capabilities, they provide a compelling alternative to Nvidia's RTX 4080. However, they fall behind in ray tracing and upscaling, where Nvidia excels.
For gamers who prioritize pure rasterization performance and native 4K gaming, the Radeon RX 7900 XTX is a great choice, outperforming the RTX 4080 while being $200 cheaper. However, those who value ray tracing and DLSS technology may find Nvidia's offering more suitable. Overall, the Radeon RX 7900 XT/XTX provides an excellent balance of performance and value, challenging Nvidia's pricing in the current GPU market.
