GeForce 820M vs Radeon HD 4550 256MB

Intro

The GeForce 820M has a core clock speed of 719 MHz and a DDR3 memory frequency of 1000 MHz. It also uses a 64-bit bus, and uses a 28 nm design. It is made up of 96 SPUs, 16 TAUs, and 4 ROPs.

Compare that to the Radeon HD 4550 256MB, which comes with a core clock frequency of 600 MHz and a DDR3 memory frequency of 800 MHz. It also makes use of a 64-bit memory bus, and uses a 55 nm design. It is made up of 80(16x5) SPUs, 8 Texture Address Units, and 4 ROPs.

Memory Bandwidth: Bandwidth is the largest amount of data (in units of MB per second) that can be transported over the external memory interface in one second. It is calculated by multiplying the card's bus width by its memory speed. If it uses DDR type RAM, the result should be multiplied by 2 again. If DDR5, multiply by 4 instead. The better the card's memory bandwidth, the better the card will be in general. It especially helps with AA, HDR and high 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 by the core clock speed of the chip. The better this number, the better the graphics 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 the graphics card can possibly write to the local memory in one second - measured in millions of pixels per second. The number is calculated by multiplying the number of colour ROPs by the the card's clock speed. ROPs (Raster Operations Pipelines - sometimes also referred to as Render Output Units) are responsible for outputting the pixels (image) to the screen. The actual pixel output rate is also dependant on quite a few other factors, especially the memory bandwidth of the card - the lower the memory bandwidth is, the lower the potential to reach the maximum fill rate.
