GeForce 9500 GT 512MB GDDR3 vs Radeon HD 3470 256MB
Intro
The GeForce 9500 GT 512MB GDDR3 comes with a clock speed of 550 MHz and a GDDR3 memory frequency of 800 MHz. It also uses a 128-bit memory bus, and uses a 55 nm design. It features 32 SPUs, 16 TAUs, and 8 Raster Operation Units.Compare those specifications to the Radeon HD 3470 256MB, which features core speeds of 800 MHz on the GPU, and 950 MHz on the 256 MB of DDR2 RAM. It features 40(8x5) SPUs as well as 4 Texture Address Units and 4 ROPs.

Memory Bandwidth: Bandwidth is the max amount of data (measured in megabytes per second) that can be transferred over the external memory interface in one second. The number is calculated by multiplying the card's bus width by its memory clock speed. If the card has DDR RAM, it should be multiplied by 2 once again. If DDR5, multiply by ANOTHER 2x. The higher the bandwidth is, the faster the card will be in general. It especially helps with AA, HDR and high resolutions.
Texel Rate: Texel rate is the maximum amount of texture map elements (texels) that are applied per second. This figure 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 in one second.
Pixel Rate: Pixel rate is the most pixels the graphics card can possibly record to the local memory in one second - measured in millions of pixels per second. Pixel rate is worked out by multiplying the number of ROPs by the the core speed of the card. ROPs (Raster Operations Pipelines - also called Render Output Units) are responsible for drawing the pixels (image) on the screen. The actual pixel fill rate is also dependant on lots of other factors, most notably the memory bandwidth of the card - the lower the bandwidth is, the lower the potential to get to the maximum fill rate.
