I found a good deal on a Diamond HD4870 model # 4870PE51GDI
There is another 4870 made by diamond (model # 4870PE51G) that's a bit more expensive but has more memory bandwidth.
The 4870PE51GDI has 112 GB/sec, but the 4870PE51G has 160 GB/sec.
They both have all the identical and clock speeds on gpu and memory. They both have 1 GB of GDDR5 on board.
Can anyone tell me why the difference in memory bandwidth?
