GeForce 930M vs Radeon HD 4550 512MB

Intro

The GeForce 930M makes use of a 28 nm design. nVidia has set the core speed at 928 MHz. The DDR3 RAM works at a speed of 900 MHz on this specific model. It features 384 SPUs along with 24 Texture Address Units and 8 ROPs.

Compare those specs to the Radeon HD 4550 512MB, which comes with GPU clock speed of 600 MHz, and 512 MB of GDDR3 memory running at 800 MHz through a 64-bit bus. It also is made up of 80(16x5) SPUs, 8 Texture Address Units, and 4 Raster Operation Units.

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

Texel Rate: Texel rate is the maximum texture map elements (texels) that are processed per second. This figure is worked out by multiplying the total number of texture units of the card by the core speed of the chip. The higher the texel rate, the better the graphics 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 amount of pixels the graphics card could possibly record to its local memory per second - measured in millions of pixels per second. The figure is worked out by multiplying the amount of Render Output Units by the the card's clock speed. ROPs (Raster Operations Pipelines - sometimes also referred to as Render Output Units) are responsible for filling the screen with pixels (the image). The actual pixel fill rate is also dependant on many other factors, especially the memory bandwidth of the card - the lower the bandwidth is, the lower the ability to reach the maximum fill rate.
