GeForce 9800 GT 1GB vs Radeon HD 6970
Intro
The GeForce 9800 GT 1GB uses a 65/55 nm design. nVidia has clocked the core speed at 600 MHz. The GDDR3 memory runs at a frequency of 900 MHz on this model. It features 112 SPUs as well as 56 Texture Address Units and 16 Rasterization Operator Units.Compare that to the Radeon HD 6970, which features GPU clock speed of 880 MHz, and 2048 MB of GDDR5 memory running at 1375 MHz through a 256-bit bus. It also features 1536 Stream Processors, 96 TAUs, and 32 ROPs.

Memory Bandwidth: Memory bandwidth is the max amount of data (in units of megabytes per second) that can be transferred over the external memory interface in a second. The number is worked out by multiplying the interface width by the speed of its memory. In the case of DDR RAM, it should be multiplied by 2 once again. If it uses DDR5, multiply by 4 instead. The better the card's memory bandwidth, the better the card will be in general. It especially helps with AA, High Dynamic Range and higher screen resolutions.
Texel Rate: Texel rate is the maximum number of texture map elements (texels) that can be processed per second. This is worked out by multiplying the total amount of texture units of the card by the core clock speed of the chip. The higher this number, the better the card will be at handling texture filtering (anisotropic filtering - AF). It is measured in millions of texels in a second.
Pixel Rate: Pixel rate is the maximum number of pixels the video card could possibly write to its local memory in one second - measured in millions of pixels per second. The figure is worked out by multiplying the number of Render Output Units by the the core speed of the card. ROPs (Raster Operations Pipelines - also sometimes called Render Output Units) are responsible for outputting the pixels (image) to the screen. The actual pixel fill rate is also dependant on quite a few other factors, most notably the memory bandwidth of the card - the lower the bandwidth is, the lower the ability to reach the maximum fill rate.
