GeForce GTX 285 2GB vs Radeon HD 6670 (OEM)
Intro
The GeForce GTX 285 2GB uses a 55 nm design. nVidia has clocked the core speed at 648 MHz. The GDDR3 memory runs at a frequency of 1242 MHz on this particular model. It features 240 SPUs as well as 80 Texture Address Units and 32 Rasterization Operator Units.Compare those specs to the Radeon HD 6670 (OEM), which has a GPU core clock speed of 800 MHz, and 512 MB of GDDR5 RAM set to run at 1000 MHz through a 128-bit bus. It also features 480 SPUs, 24 TAUs, and 8 ROPs.

Memory Bandwidth: Memory bandwidth is the max amount of data (counted in megabytes per second) that can be moved over the external memory interface in one second. It is calculated by multiplying the interface width by its memory clock speed. If the card has DDR RAM, it must be multiplied by 2 again. If DDR5, multiply by ANOTHER 2x. The higher the memory bandwidth, the faster 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 are applied in one second. This number is worked out by multiplying the total number of texture units of the card by the core clock speed of the chip. The better this number, 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 video card could possibly record to the local memory per second - measured in millions of pixels per second. The figure is calculated by multiplying the amount of ROPs by the clock speed of the card. ROPs (Raster Operations Pipelines - also sometimes called Render Output Units) are responsible for filling the screen with pixels (the image). The actual pixel rate is also dependant on lots of other factors, most notably the memory bandwidth of the card - the lower the memory bandwidth is, the lower the ability to get to the maximum fill rate.
