GeForce 9500 GT 1GB GDDR3 vs Radeon HD 3470 256MB

Intro

The GeForce 9500 GT 1GB GDDR3 uses a 55 nm design. nVidia has clocked the core speed at 550 MHz. The GDDR3 RAM is set to run at a frequency of 800 MHz on this model. It features 32 SPUs as well as 16 TAUs and 8 ROPs.

Compare all of that to the Radeon HD 3470 256MB, which uses a 55 nm design. AMD has clocked the core frequency at 800 MHz. The DDR2 memory runs at a speed of 950 MHz on this specific model. It features 40(8x5) SPUs as well as 4 TAUs and 4 ROPs.

Memory Bandwidth: Memory bandwidth is the maximum amount of information (measured in MB per second) that can be transferred past the external memory interface in one second. It's worked out by multiplying the interface width by the speed of its memory. In the case of DDR type memory, the result should be multiplied by 2 once again. If it uses DDR5, multiply by 4 instead. The better the bandwidth is, 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 texture map elements (texels) that are applied per second. This figure is worked out by multiplying the total amount of texture units by the core clock speed of the chip. The higher the texel rate, the better the card will be at texture filtering (anisotropic filtering - AF). It is measured in millions of texels applied in one second.

Pixel Rate: Pixel rate is the most pixels that the graphics card could possibly record to the local memory in one second - measured in millions of pixels per second. Pixel rate is calculated by multiplying the amount of Raster Operations Pipelines by the the core speed of the card. ROPs (Raster Operations Pipelines - also called Render Output Units) are responsible for outputting the pixels (image) to the screen. The actual pixel output rate is also dependant on many other factors, especially the memory bandwidth - the lower the memory bandwidth is, the lower the potential to reach the max fill rate.
