As reported by the insider @ Kepler_L2, the chip itself Navi 31 made its appearance within the LLVM compilation platform, on files concerning drivers and development tools for Linux. According to what emerged, AMD is working on four models of video cards, of which the code names are:
GFX1100 (Possible Navi 31) GFX1101 (Possible Navi 32) GFX1102 (Possible Navi 33) GFX1103 (Possible APU Phoenix) According to what shared by @ greymon55, the GFX110 chip that should equip the Radeon RX 7900 XT should benefit from a dizzying increase in frequency, approaching or even exceeding 3GHz. With 15,360 stream processors, the card would therefore be able to touch 100 TFLOP in FP32 (92 TFLOP to be precise) already with standard frequencies, a value to which it could approach further or reach in overclock mode.
The chip AMD's Navi 31, of which some specifications had already been leaked along with the rest of the range, will make use of WGP (Work Group Processors) units, each of which contains two CU (Compute Units) equipped with twice as many SIMD32 clusters as those present in RDNA 2 chips. As you can see from the diagram, Navi 31 will have two GCDs (Graphics Core Die), each consisting of three Shader Engines. Each Shader Engine includes two Shader Arrays, in turn equipped with five WGPs of 8 FP32 units each.| ); }

The MCD (Multi Cache Die) module, which will include 256 to 512 MB of Infinity Cache, is connected to the two GCDs via a next generation Infinity Fabric interconnect. The new GPUs are also expected to have a 256-bit memory bus, through the use of eight 32-bit controllers. According to further rumors, RDNA 3 chips may also make use of 3D stacking.
AMD's new RDNA 3 range is expected to launch in Q4 2022, but new Radeons are more than likely to be available only starting from 2023.
