GeForce 9800 GTX vs Radeon HD 6670 (OEM)
Intro
The GeForce 9800 GTX features a GPU core clock speed of 675 MHz, and the 512 MB of GDDR3 memory runs at 1100 MHz through a 256-bit bus. It also is made up of 128 Stream Processors, 64 Texture Address Units, and 16 Raster Operation Units.Compare those specs to the Radeon HD 6670 (OEM), which comes with GPU core speed of 800 MHz, and 512 MB of GDDR5 memory running at 1000 MHz through a 128-bit bus. It also is made up of 480 Stream Processors, 24 Texture Address Units, and 8 Raster Operation Units.

Memory Bandwidth: Memory bandwidth is the maximum amount of data (in units of MB per second) that can be transported past the external memory interface in one second. The number is worked out by multiplying the card's bus width by the speed of its memory. If the card has DDR memory, it should be multiplied by 2 once again. If DDR5, multiply by 4 instead. The better the bandwidth is, the better the card will be in general. It especially helps with anti-aliasing, High Dynamic Range and higher screen resolutions.
Texel Rate: Texel rate is the maximum amount of texture map elements (texels) that can be applied per second. This figure is worked out by multiplying the total texture units by the core speed of the chip. The better the texel rate, the better the graphics 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 most pixels the graphics card could possibly write to the local memory per second - measured in millions of pixels per second. The figure is calculated by multiplying the number of Raster Operations Pipelines by the the card's clock speed. ROPs (Raster Operations Pipelines - aka Render Output Units) are responsible for outputting the pixels (image) to the screen. The actual pixel fill rate also depends on lots of other factors, most notably the memory bandwidth - the lower the bandwidth is, the lower the potential to reach the maximum fill rate.
