GeForce GTS 450 1GB vs Radeon HD 4830 1GB

Intro

The GeForce GTS 450 1GB uses a 40 nm design. nVidia has set the core speed at 783 MHz. The GDDR5 memory works at a frequency of 902 MHz on this model. It features 192 SPUs as well as 32 Texture Address Units and 16 ROPs.

Compare all that to the Radeon HD 4830 1GB, which features core clock speeds of 575 MHz on the GPU, and 900 MHz on the 1024 MB of GDDR4 RAM. It features 640(128x5) SPUs as well as 32 TAUs and 16 Rasterization Operator Units.

Memory Bandwidth: Memory bandwidth is the maximum amount of information (counted in megabytes per second) that can be moved over the external memory interface in a second. It's worked out by multiplying the card's interface width by the speed of its memory. If it uses DDR memory, it must be multiplied by 2 again. If it uses DDR5, multiply by 4 instead. The better the card's memory bandwidth, the better the card will be in general. It especially helps with anti-aliasing, HDR and high resolutions.

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

Pixel Rate: Pixel rate is the maximum amount of pixels that the graphics chip could possibly record to its local memory per second - measured in millions of pixels per second. The number is worked out by multiplying the amount of ROPs 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 output rate also depends on quite a few other factors, especially the memory bandwidth - the lower the bandwidth is, the lower the potential to reach the maximum fill rate.
