GeForce 930M vs Radeon HD 4550 256MB

Intro

The GeForce 930M features a GPU core clock speed of 928 MHz, and the 2048 MB of DDR3 memory is set to run at 900 MHz through a 64-bit bus. It also is comprised of 384 Stream Processors, 24 Texture Address Units, and 8 ROPs.

Compare all that to the Radeon HD 4550 256MB, which features clock speeds of 600 MHz on the GPU, and 800 MHz on the 256 MB of DDR3 memory. It features 80(16x5) SPUs along with 8 TAUs and 4 Rasterization Operator Units.

Memory Bandwidth: Bandwidth is the largest amount of data (measured in megabytes per second) that can be transferred past the external memory interface in one second. The number is calculated by multiplying the card's interface width by its memory speed. If the card has DDR type RAM, it should be multiplied by 2 again. If it uses DDR5, multiply by ANOTHER 2x. The higher the bandwidth is, the better the card will be in general. It especially helps with anti-aliasing, HDR and higher screen resolutions.

Texel Rate: Texel rate is the maximum texture map elements (texels) that are applied per second. This is calculated 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 video card will be at texture filtering (anisotropic filtering - AF). It is measured in millions of texels processed in a second.

Pixel Rate: Pixel rate is the maximum number of pixels that the graphics card can possibly record to the local memory per second - measured in millions of pixels per second. The number is calculated by multiplying the amount of Render Output Units by the the core speed of the card. ROPs (Raster Operations Pipelines - aka Render Output Units) are responsible for filling the screen with pixels (the image). The actual pixel output rate is also dependant on many other factors, especially the memory bandwidth - the lower the memory bandwidth is, the lower the ability to get to the max fill rate.
