GeForce GT 430 1GB vs Radeon HD 5450

Intro

The GeForce GT 430 1GB has a GPU clock speed of 700 MHz, and the 1024 MB of GDDR3 memory is set to run at 900 MHz through a 128-bit bus. It also features 96 SPUs, 16 TAUs, and 4 ROPs.

Compare those specs to the Radeon HD 5450, which uses a 40 nm design. AMD has set the core speed at 650 MHz. The DDR3 RAM runs at a speed of 800 MHz on this model. It features 80(16x5) SPUs as well as 8 Texture Address Units and 4 ROPs.

Memory Bandwidth: Bandwidth is the largest amount of information (measured in MB per second) that can be moved over the external memory interface in a second. It's worked out by multiplying the card's bus width by the speed of its memory. In the case of DDR memory, the result should be multiplied by 2 once again. If DDR5, multiply by 4 instead. The higher the memory bandwidth, the faster the card will be in general. It especially helps with anti-aliasing, HDR and higher screen resolutions.

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

Pixel Rate: Pixel rate is the most pixels that the graphics chip can possibly record to the local memory in a second - measured in millions of pixels per second. The number is calculated by multiplying the amount of ROPs by the the core 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 quite a few other factors, especially the memory bandwidth of the card - the lower the bandwidth is, the lower the ability to reach the max fill rate.
