Facts and statements
- GDDR7 divides each 32-bit channel into two independent 16-bit sub-channels, reducing burst payload size to 32 bytes (BL16) or 64 bytes (BL32) per transaction. (high confidence) [source]
- The 32-byte minimum burst length directly matches L2 cacheline fill requirements for fine-grained tensor activations without fetching unneeded contiguous memory bytes. (high confidence) [source]
Children
- No children recorded.
