Not as much performance is lost because of the lower 128-bit bandwidth because the technology of the GDDR5 makes up for the lack of boos. ATI did not have to compensate like they did with the HD 4750 when they implemented 128-bit but using GDDR5 to make up the performance. In the HD 5750 you get them both but double the memory. Effective clocked at 4600MHz quad split or 1150MHz single.
The Sapphire model we will be taking a look at today is based Juniper GPU which is constructed on the 40nm manufacturing process and the GPU is clocked at 700MHz. So this means less power usage while being a speedy video card at the same time. At such speed the HD 5750 looks to be the ideal partner to the Intel P55 and an Intel i5 750 CPU or AMD 785 and a X4 Quad processor. Enough of the numbers and other technology genre lets get into the visuals and testing modes of the article.
