Default Graphic Card

I was curious as to why a GPU with a higher bit has slower specs than that of a lower bit rate GPU. Thanks in advance.

By higher and lower "bit", what do you mean?<<xxx>> Bits wide interface?

Compare these two cards and look at all specs...

http://www.newegg.com/Product/Produc...82E16814102854
Cheaper but says it has higher clock speeds but only 128 bit vs.

http://www.newegg.com/Product/Produc...82E16814127464
Which has 448 bits but slower clock speed.

im not that good with graphics cards but i'll try to explain what i know.
The bits represent how fast the graphics card will communicate with the computer. The more you have then the faster it'll be. I'll try to give an example. Lets say that the 128-bit graphics card can take 1GB of information from the computer at a time. then a 256-bit card could take twice that amount.

The "bit interface" is how many bits wide the memory address is.

Quote:
This is the form of interface the graphics core has with its video RAM. As a number, it refers to how much data, in bits, can be read from or written to the memory every clock cycle the memory goes through

Makes sense, so you want large amount of bit at a nice clock speed. Thanks
