GeForce GTS 250 1GB vs Radeon HD 5830

Intro

The GeForce GTS 250 1GB has core clock speeds of 738 MHz on the GPU, and 1100 MHz on the 1024 MB of GDDR3 memory. It features 128 SPUs as well as 64 Texture Address Units and 16 Rasterization Operator Units.

Compare that to the Radeon HD 5830, which features a GPU core clock speed of 800 MHz, and 1024 MB of GDDR5 memory running at 1000 MHz through a 256-bit bus. It also features 1120(224x5) Stream Processors, 56 Texture Address Units, and 16 Raster Operation Units.

Memory Bandwidth: Memory bandwidth is the largest amount of data (measured in MB per second) that can be moved over the external memory interface in one second. The number is calculated by multiplying the bus width by its memory clock speed. If it uses DDR memory, the result should be multiplied by 2 once again. If DDR5, multiply by 4 instead. The better the memory bandwidth, the better 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 number of texture map elements (texels) that are processed in one second. This figure is calculated by multiplying the total amount of texture units of the card by the core clock speed of the chip. The better this number, the better the video card will be at handling texture filtering (anisotropic filtering - AF). It is measured in millions of texels processed in one second.

Pixel Rate: Pixel rate is the maximum number of pixels the video 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 number of ROPs by the the card's clock speed. ROPs (Raster Operations Pipelines - also sometimes called Render Output Units) are responsible for outputting the pixels (image) to the screen. The actual pixel rate also depends on quite a few other factors, most notably the memory bandwidth of the card - the lower the memory bandwidth is, the lower the potential to reach the max fill rate.
