RDNA 3 is the first GPU to use a 'chiplet' method that combines multiple dies, and the GPU die manufactured with the 5nm process and the cache memory manufactured with the 6nm process are combined in one package. .

By adopting the chiplet method, the memory bandwidth is improved to a maximum of 5.3 TB / s. In addition, the processing performance is 61 TFLOPS, which is less than the 82.6 TFLOPS of the NVIDIA flagship GPU 'GeForce RTX 4090', but exceeds the 48.7 TFLOPS of the 'GeForce RTX 4080'.

RDNA 3 also has improved power saving performance, and the performance per power consumption is 54% higher than RDNA 2.

AMD has announced two types of GPUs that use the above RDNA 3 architecture: 'Radeon RX 7900 XTX' and 'Radeon RX 7900 XT'.

The specifications of Radeon RX 7900 XTX and Radeon RX 7900 XT revealed by AMD are as follows. The top model Radeon RX 7900 XTX has 24GB of video memory.

model AMD Radeon RX 7900 XTX AMD Radeon RX 7900 XT
Number of compute units 96 84
video memory 24GB 20GB
game frequency 2.3GHz 2.0 GHz
Maximum boost frequency 2.5GHz 2.4GHz
memory interface 384-bit 320-bit
Infinity Cache 96MB 80MB
Power consumption (TBP) 355W 300W
Suggested retail price $ 999 (about 148,000 yen) $ 899 (about 133,000 yen)

The Radeon RX 7900 XTX is said to have improved gaming performance by 1.7 times compared to the previous generation top model 'Radeon RX 6950 XT'.

The 4K gaming performance of the Radeon RX 7900 XTX is below. 'Apex Legends' records 295fps, 'Overwatch 2' records 355fps, and 'VALORANT' records a very high frame rate of 704fps.

Also, when AMD's unique super-resolution technology '

AMD FidelityFX Super Resolution (FSR) ' is enabled, 'Cyberpunk 2077' can be operated at 62 fps even with a high load setting of 4K and ray tracing enabled.

Furthermore, by enabling FSR, it is also possible to run the 8K setting of 'Assassin's Creed Valhalla' at 96fps.

The width of the Radeon RX 7900 XTX reference board is 287mm, which is 11mm longer than the Radeon RX 6950 XT reference board (276mm). For this reason, AMD appeals that 'Radeon RX 7900 XTX can smoothly transition from Radeon RX 6950 XT.'

Both the Radeon RX 7900 XTX and Radeon RX 7900 XT are expected to launch on December 13th, 2022.
