Ddr3 vs ddr5 radeon 6770

[divJ]

whats the difference between the radeon 6770 ddr3 and ddr5 ?
theres a huge difference in the pice... why ?

 

[azeem40]

GDDR5 is quad pumped so its transfer rates are twice as high as DDR3, so if a GDDR5 card has a 128 bit bus and a DDR3 card has a 256 bit bus their memory bandwidth will be basically identical.

The performance difference between DDR3 and DDR5 will likely be somewhere between 5% - 10%.
