![]() Unsurprisingly, the move from GDDR5 to GDDR6 saw big development in this area: the number of data transfers per clock cycle has doubled, from two to four, and individual memory chips can now be read in dual-channel arrangements rather than just single channel. Those requirements mean that graphics memory needs to excel with parallel computing. In computing terms, though, these files are actually being moved relatively slowly.Ĭonventional PC memory moves smaller files at higher speeds, so it requires less bandwidth but better latency. Graphics memory needs huge bandwidth rather than low latency in order to work well – because graphics cards move lots of large files simultaneously. In turn, that means it’s got to be built differently. GDDR6 memory is specialist technology that address different tasks than conventional PC memory.
