GeForce 9600 GSO 512MB vs Radeon HD 3850 1GB

Intro

The GeForce 9600 GSO 512MB uses a 65/55 nm design. nVidia has clocked the core frequency at 650 MHz. The GDDR3 RAM works at a speed of 900 MHz on this model. It features 96 SPUs along with 48 TAUs and 16 ROPs.

Compare all of that to the Radeon HD 3850 1GB, which comes with core clock speeds of 668 MHz on the GPU, and 828 MHz on the 1024 MB of GDDR3 memory. It features 320(64x5) SPUs along with 16 TAUs and 16 ROPs.

Memory Bandwidth: Bandwidth is the maximum amount of information (in units of megabytes per second) that can be moved across the external memory interface within a second. The number is calculated by multiplying the card's interface width by its memory speed. In the case of DDR RAM, the result should be multiplied by 2 once again. If DDR5, multiply by ANOTHER 2x. The better the card's memory bandwidth, 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 is worked out by multiplying the total texture units of the card by the core speed of the chip. The better the texel rate, the better the graphics 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 maximum number of pixels that the graphics chip can possibly write to its local memory in one second - measured in millions of pixels per second. The number is worked out by multiplying the number of ROPs by the the card's clock speed. ROPs (Raster Operations Pipelines - aka Render Output Units) are responsible for filling the screen with pixels (the image). The actual pixel rate is also dependant on many other factors, especially the memory bandwidth - the lower the bandwidth is, the lower the ability to reach the max fill rate.
