GeForce GT 230 vs Radeon HD 5830

Intro

The GeForce GT 230 has a core clock speed of 550 MHz and a DDR3 memory speed of 800 MHz. It also uses a 192-bit memory bus, and makes use of a 40 nm design. It is made up of 32 SPUs, 16 Texture Address Units, and 8 Raster Operation Units.

Compare all of that to the Radeon HD 5830, which uses a 40 nm design. AMD has set the core speed at 800 MHz. The GDDR5 RAM runs at a speed of 1000 MHz on this card. It features 1120(224x5) SPUs as well as 56 TAUs and 16 Rasterization Operator Units.

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

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

Pixel Rate: Pixel rate is the maximum number of pixels the video card can possibly record to its local memory in a second - measured in millions of pixels per second. The number is worked out by multiplying the number of Raster Operations Pipelines by the clock speed of the card. ROPs (Raster Operations Pipelines - also called Render Output Units) are responsible for drawing the pixels (image) on the screen. The actual pixel output rate is also dependant on many other factors, especially the memory bandwidth - the lower the bandwidth is, the lower the potential to reach the max fill rate.
