GeForce 9500 GT 1GB GDDR3 vs Radeon HD 3470 256MB
Intro
The GeForce 9500 GT 1GB GDDR3 makes use of a 55 nm design. nVidia has clocked the core frequency at 550 MHz. The GDDR3 RAM is set to run at a frequency of 800 MHz on this particular card. It features 32 SPUs as well as 16 TAUs and 8 Rasterization Operator Units.Compare that to the Radeon HD 3470 256MB, which makes use of a 55 nm design. AMD has set the core frequency at 800 MHz. The DDR2 memory runs at a frequency of 950 MHz on this specific card. It features 40(8x5) SPUs as well as 4 TAUs and 4 ROPs.

Memory Bandwidth: Memory bandwidth is the max amount of data (measured in MB 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 speed. If it uses DDR RAM, it must be multiplied by 2 once again. If it uses DDR5, multiply by ANOTHER 2x. The higher the memory bandwidth, the better the card will be in general. It especially helps with AA, HDR and higher screen resolutions.
Texel Rate: Texel rate is the maximum number of texture map elements (texels) that are processed per second. This is calculated by multiplying the total texture units of the card by the core speed of the chip. The higher this number, the better the video card will be at texture filtering (anisotropic filtering - AF). It is measured in millions of texels processed in a second.
Pixel Rate: Pixel rate is the most pixels that the graphics card can possibly write to the local memory per second - measured in millions of pixels per second. The figure is worked out by multiplying the number of Raster Operations Pipelines by the the core speed of the card. ROPs (Raster Operations Pipelines - aka Render Output Units) are responsible for outputting the pixels (image) to the screen. The actual pixel fill rate is also dependant on many other factors, especially the memory bandwidth of the card - the lower the bandwidth is, the lower the potential to reach the max fill rate.
