GeForce 9500 GT 512MB GDDR3 vs Radeon HD 3470 512MB
Intro
The GeForce 9500 GT 512MB GDDR3 uses a 55 nm design. nVidia has set the core frequency at 550 MHz. The GDDR3 RAM runs at a speed of 800 MHz on this specific model. It features 32 SPUs along with 16 Texture Address Units and 8 ROPs.Compare all of that to the Radeon HD 3470 512MB, which has GPU core speed of 800 MHz, and 512 MB of GDDR3 memory running at 950 MHz through a 128-bit bus. It also features 40(8x5) SPUs, 4 Texture Address Units, and 4 ROPs.

Memory Bandwidth: Bandwidth is the maximum amount of data (in units of MB per second) that can be transferred over the external memory interface in a second. It is worked out by multiplying the interface width by its memory speed. If it uses DDR RAM, it should be multiplied by 2 once again. If it uses DDR5, multiply by ANOTHER 2x. The higher the bandwidth is, the faster the card will be in general. It especially helps with anti-aliasing, HDR and higher screen resolutions.
Texel Rate: Texel rate is the maximum texture map elements (texels) that are applied per second. This number is worked out by multiplying the total number of texture units of the card by the core speed of the chip. The better the texel rate, the better the card will be at handling texture filtering (anisotropic filtering - AF). It is measured in millions of texels per second.
Pixel Rate: Pixel rate is the maximum number of pixels the graphics card could possibly write to its local memory in a second - measured in millions of pixels per second. The number is calculated by multiplying the amount of Raster Operations Pipelines by the clock speed of the card. ROPs (Raster Operations Pipelines - aka Render Output Units) are responsible for drawing the pixels (image) on the screen. The actual pixel output rate is also dependant on quite a few other factors, especially the memory bandwidth of the card - the lower the memory bandwidth is, the lower the potential to get to the maximum fill rate.
