WebJul 9, 2024 · A larger cache line also facilitates wider memory interfaces when burst length is fixed. Increasing DRAM burst length facilitates higher bandwidth; DDR5 moved to a burst length of 16, pushing DIMMs into using two 32-bit wide channels to be compatible with x86's de facto standardization on 64-byte cache lines. WebSep 16, 2024 · It is very likely 32 (tiny, parallel) wires. Bus-width divided by register-size is generally a (possibly negative) power of 2 for efficiency. Otherwise, there's not necessarily any relation. A single track of wire can handle one bit of data (bit = binary digit). A 32 bit bus has 32 tracks (or less, if multiplexed)
