11March 3 afternoon，AMD hosts a special livestream event called "together we advance_gaming"，Officially released Radeon RX based on next-generation RDNA 3 architecture GPU 7900 XTX and Radeon RX 7900 XT graphics card，Provides better ray tracing and raster performance。
Radeon RX 7900 XTX and Radeon RX 7900 XT is equipped with Navi 31 GPU，Only equipped with two 8Pin external power supply interfaces，Power consumption is 355W and 300W respectively。AMD says，RDNA3 architecture delivers 54% higher performance per watt than RDNA2， Radeon RX 7900 XTX compared to the previous generation flagship Radeon RX 6950 XT ，70% better performance at 4K resolution， Radeon RX 7900 XT will also outperform Nvidia's GeForce RTX 3090 Of 。
Navi 31 uses TSMC's 5nm process and small chip design，AMD's first consumer-grade GPU in an MCM multi-chip package，Has 58 billion transistors。It comes with one GCD (Graphics Computing Chip) and six MCDs (Multi-Cache I/O Chips)，Two different processes will be used at the same time，The former is TSMC's 5nm，The latter is 6nm。Equipped with optimized next-generation Infinity Cache，Not only provides higher density and lower power consumption，Also improves effective bandwidth and hit rate。Fully configured Navi 31 delivers 61 TFLOPs of single-precision compute performance，The Navi 21 based on the RDNA 2 architecture is 23 TFLOPs。
Radeon RX 7900 XTX has 6144 stream processors，base frequency、game frequency、The acceleration frequency is 1.9 GHz respectively、2.3GHz和2.5 GHz，Video memory is 24GB of GDDR6，Video memory width is 384 bits，Video memory at 20 Gbps，Memory bandwidth of 960 GB/s，Infinity Cache is 96MB。
Radeon RX 7900 XT features a pared down Navi 31，5376 stream processors，base frequency、game frequency、The acceleration frequency is 1.5 GHz respectively、2.0GHz和2.4 GHz，Video memory is 20GB of GDDR6，Video memory is 320 bits wide，Video memory at 20 Gbps，Video memory bandwidth is 800 GB/s，Infinity Cache is 80MB。
AMD also brings a new display engine， Radeon RX 7900 XTX and Radeon RX 7900 XT is the first Radeon graphics card to support DisplayPort 2.1，8K@165Hz or 4K@480Hz display output with a single cable，Can meet the requirements of UHBR13.5 link rate (54Gbps)，I believe that the new display engine will also appear on the integrated display in the future。
also，The new generation graphics card also supports FSR 3 to further improve the frame rate performance，and HYPER-RX technology，Enables "one-click performance and latency improvements"，But both are temporarily unavailable，It won't be released until next year，Competing with NVIDIA DLSS and Reflex。
Radeon RX 7900 XTX is priced at $999， Radeon RX 7900 XT is priced at $899，It will go on sale on December 13, 2022。
