WebMar 18, 2011 · The value: 32bytes for 1byte-words, 64bytes for 2byte-words and 128bytes for higher-byte words is the maximum size of the accessed segment. If, for example, each thread is fetching 2-byte word and your access is perfectly aligned, the memory access will be reduced to use only 32-byte line fetch.
