+CK Tile Hardware Documentation - Radeon / Navi
+********************************************************************
+
+This section provides in-depth coverage of hardware-specific concepts and optimizations for CK Tile on AMD GPUs.
+
+Overview
+========
+
+Understanding the underlying hardware architecture is crucial for achieving optimal performance with CK Tile. This documentation covers differences between AMD CDNA and AMD RDNA across the following areas:
+
+- Instruction Set Architecture (ISA)
+- Memory hierarchy and optimization techniques
+- Practical examples of high-performance kernels
+
+Key Hardware Considerations
+===========================
+
+When using CK Tile, keep these hardware aspects in mind:
+
+Memory Hierarchy
+----------------
+
+The memory hierarchy on Radeon / Navi is similar to the memory hiararchy on CDNA / Instinct.  It is organised into Global Memory, L2/Infinity Cache, LDS, Registers.
+
+[TODO: table with sizes at all levels for MI200, MI300, Navi31, Navi48 ]
+
+Compute Resources
+------------------
+
+1. **Wavefront Execution**: multiple threads in lockstep as on CNDA / Instinct
+
+   - 32 threads (in contrast to 64 on CDNA / Instinct)
+
+2. **Matrix Units**: specialized Matrix Multiple Units as on CDNA / Instinct
