It's not the first GDDR5 chip made, but Samsung claims it's the fastest.
Samsung claims to have invented the world's fastest graphics memory, capable of transferring data at 6Gb/sec.
The series five, graphics double-data-rate (GDDR5) chips are more than four times faster than those found in today's consoles, according to Samsung, and will find their way into desktop PCs, notebooks and workstations.
The chips will be introduced next year at a density of 512Mb (16Mb x 32), with Samsung claiming that GDDR5 will claim half of the top-end PC graphics market by 2010.
The first of these chips came from Qimonda last month, which began sampling a 512Mb GDDR 5 chip. However, Hynix's chip has a data transfer rate of 5Gb/s vs the 6Gb/s Samsung claims.
