The RDNA 4 architecture represents the latest evolution of AMD’s GPU technology and demonstrates significant advances in efficiency, performance and functionality. With the integration of advanced manufacturing technologies, including an optimized chiplet design, RDNA 4 achieves significantly higher compute performance while reducing power consumption. The architecture introduces revised compute units that are designed for both traditional graphics tasks and the demanding requirements of real-time ray tracing. For the ray tracing units in particular, AMD has focused on the processing of ray paths per second, which, in combination with the improved AI accelerators, ensures more realistic and detailed gaming scenarios. In addition, the new Media Engine offers optimized support for modern video formats such as H.264, HEVC and AV1, which are processed more efficiently through improved hardware acceleration.
In addition to the specific improvements to FSR 4 and Anti-Lag 2, RDNA 4 offers a host of new Radeon technologies. The Infinity Cache technology has been further optimized to achieve higher bandwidth and lower latencies. RDNA 4 also sets the benchmark for energy efficiency by achieving higher performance per watt, reducing operating costs and thermal requirements. These advances make the architecture ideal for modern gaming and creative workloads that require high computing power and efficiency.
FidelityFX Super Resolution 4 (FSR 4) and Anti-Lag 2
With FidelityFX Super Resolution 4 (FSR 4), AMD presents a new generation of upscaling technologies designed to take the gaming experience to a new level. FSR 4 combines temporal and spatial upscaling with an innovative frame generation function that generates additional frames and thus increases the perceived frame rate. This technology, which relies heavily on the AI acceleration of the RDNA 4 architecture, promises a more realistic display and smoother movements, even in demanding gaming scenarios. This apparently also marks the end of the hardware-independent implementation of FSR, which made it possible to use the technology not only on Radeon GPUs, but also on competitor products, allowing AMD to appeal to a broad user base.
Anti-Lag 2 is a further development of input lag reduction and is specially tailored to the needs of competitive gamers. The technology synchronizes data processing between the CPU and GPU more efficiently, reducing input lag to a minimum. Anti-Lag 2 uses the new hardware capabilities of RDNA 4 to automatically detect games and apply the optimal configurations without the user having to make any manual adjustments. This dynamic optimization makes the technology attractive for both casual gamers and professional eSports players.
Radeon RX 9070 XT and RX 9070
The Radeon RX 9070 XT and RX 9070 are the first GPUs based on the RDNA-4 architecture and have been specially developed for high-end gaming and creative applications. The RX 9070 XT is characterized by a larger number of compute units and a higher clock speed, making it the ideal choice for 4K gaming and demanding workloads. The RX 9070, on the other hand, offers slightly reduced performance with lower power consumption and is aimed at users who prefer a powerful but more efficient solution. Both models benefit from advances in ray tracing technology. Especially when FidelityFX Super Resolution (FSR) 4 is activated, a significant improvement in visual quality should be offered without any significant loss of performance. These optimizations illustrate AMD’s focus on increased efficiency, especially in graphically intensive games.
Another area in which RDNA 4 stands out is content creation. Impressive performance increases were achieved in benchmarks such as Blender, Cinebench 2024 and V-Ray. The optimized compute architecture and faster memory connection thanks to GDDR7 contribute to faster render times and smoother processing of complex projects. RDNA 4 shows a significantly higher performance per watt, which makes it an attractive option for professional creatives who rely on energy-efficient yet powerful hardware.
The media engine was also mentioned, particularly in terms of its AV1 encoding and decoding capabilities. Here, RDNA 4 shows a higher VMAF quality compared to RDNA 3, which is due to the improved hardware acceleration and the integration of advanced algorithms. RDNA 4 can be expected to play a crucial role not only for gaming, but also for streaming and multimedia applications. The combination of increased graphics performance, improved power efficiency and advanced media and AI capabilities positions the architecture as a leading solution for a wide range of applications.
AMD is positioning the RX 9070 XT and RX 9070 as direct competition to NVIDIA’s GeForce RTX 4080 and RTX 4070 Ti. The RX 9070 XT is aimed at users looking for similar performance to the RTX 4080, particularly in 4K gaming and applications with ray tracing enabled. The RX 9070, on the other hand, is placed in a similar segment to the RTX 4070 Ti and is optimized for QHD gaming. With the integration of FSR 4 and Anti-Lag 2 as well as advances in energy efficiency and AI features, AMD aims to offer an attractive alternative to NVIDIA, especially for price-conscious buyers who do not want to compromise on performance. Both models are scheduled for launch in the first quarter of 2025, significantly raising expectations for the next generation of GPUs in both gaming and creative applications.
The information was provided by AMD in advance under NDA. The only condition was compliance with the embargo period.
