GeForce 9800 GTX+ vs Radeon HD 4830 1GB

Intro

The GeForce 9800 GTX+ features a GPU core speed of 738 MHz, and the 512 MB of GDDR3 RAM is set to run at 1100 MHz through a 256-bit bus. It also is comprised of 128 SPUs, 64 TAUs, and 16 Raster Operation Units.

Compare all that to the Radeon HD 4830 1GB, which features GPU clock speed of 575 MHz, and 1024 MB of GDDR4 memory running at 900 MHz through a 256-bit bus. It also features 640(128x5) Stream Processors, 32 Texture Address Units, and 16 Raster Operation Units.

Memory Bandwidth: Memory bandwidth is the largest amount of information (measured in megabytes per second) that can be transferred across the external memory interface in one second. The number is worked out by multiplying the bus width by its memory clock speed. If it uses DDR memory, it should be multiplied by 2 again. If DDR5, multiply by ANOTHER 2x. The higher the card's memory bandwidth, the better the card will be in general. It especially helps with anti-aliasing, High Dynamic Range and high resolutions.

Texel Rate: Texel rate is the maximum amount of texture map elements (texels) that can be applied per second. This figure is worked out by multiplying the total amount of texture units of the card by the core speed of the chip. The higher this number, the better the video card will be at handling texture filtering (anisotropic filtering - AF). It is measured in millions of texels applied in one second.

Pixel Rate: Pixel rate is the maximum number of pixels that the graphics chip can possibly write to the local memory in one second - measured in millions of pixels per second. Pixel rate is calculated by multiplying the number of Raster Operations Pipelines by the the core speed of the card. ROPs (Raster Operations Pipelines - also sometimes called 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, most notably the memory bandwidth - the lower the memory bandwidth is, the lower the potential to get to the max fill rate.
