AMD RDNA3 ISA guide is now available to help developers with low-level architecture optimizations

AMD publishes 606-page RDNA3 Instruction Set Architecture document Nearly a month after Radeon RX 7900 were launched, AMD is now sharing a document featuring details on low-level instructions for RDNA3 architecture. This very sophisticated programming guide is intended for developers who would like to take advantage of the architecture by using specific instructions that were enabled or modified for the third generation RDNA. AMD ISA provides knowledge on RDNA3 shader code execution model, memory hierarchy and lists all available instructions. This could be helpful for low-level optimizations or compiler-level tuning, notes Phoronix. AMD RDNA™ 3 Instruction Set Architecture (ISA) reference...
