GeForce 830M vs Radeon HD 4550 512MB

Intro

The GeForce 830M comes with a GPU core clock speed of 1029 MHz, and the 2048 MB of DDR3 memory runs at 900 MHz through a 64-bit bus. It also features 256 Stream Processors, 16 TAUs, and 8 ROPs.

Compare those specs to the Radeon HD 4550 512MB, which has a GPU core clock speed of 600 MHz, and 512 MB of GDDR3 RAM running at 800 MHz through a 64-bit bus. It also features 80(16x5) SPUs, 8 Texture Address Units, and 4 ROPs.

Memory Bandwidth: Memory bandwidth is the maximum amount of information (in units of 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 the speed of its memory. If it uses DDR RAM, it must be multiplied by 2 once again. If it uses DDR5, multiply by ANOTHER 2x. 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 amount of texture map elements (texels) that can be processed in one second. This figure is worked out by multiplying the total amount of texture units of the card by the core clock speed of the chip. The higher this number, the better the graphics card will be at texture filtering (anisotropic filtering - AF). It is measured in millions of texels processed in one second.

Pixel Rate: Pixel rate is the most pixels the video card can possibly record to its local memory in a second - measured in millions of pixels per second. The number is calculated by multiplying the amount of colour ROPs by the the core 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 output 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 get to the maximum fill rate.
