VS

Radeon HD 4830 1GB vs Radeon HD 6570 (OEM) 2GB

Intro

The Radeon HD 4830 1GB features a GPU clock speed of 575 MHz, and the 1024 MB of GDDR4 memory is set to run at 900 MHz through a 256-bit bus. It also is made up of 640(128x5) SPUs, 32 TAUs, and 16 Raster Operation Units.

Compare all that to the Radeon HD 6570 (OEM) 2GB, which features GPU clock speed of 650 MHz, and 1024 MB of GDDR5 memory running at 1000 MHz through a 128-bit bus. It also features 480 SPUs, 24 Texture Address Units, and 8 ROPs.

Memory Bandwidth: Memory bandwidth is the maximum amount of data (measured in MB per second) that can be transferred over the external memory interface within a second. It's calculated by multiplying the interface width by its memory clock speed. In the case of DDR memory, it should be multiplied by 2 again. If it uses DDR5, multiply by ANOTHER 2x. The higher the bandwidth is, the faster the card will be in general. It especially helps with AA, High Dynamic Range and high resolutions.

Texel Rate: Texel rate is the maximum amount of texture map elements (texels) that can be applied in one second. This is worked out by multiplying the total number of texture units of the card by the core speed of the chip. The better 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 most pixels the video card can possibly record to the local memory per second - measured in millions of pixels per second. The number is calculated by multiplying the number of Render Output Units 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 is also dependant on quite a few other factors, especially the memory bandwidth - the lower the bandwidth is, the lower the potential to reach the maximum fill rate.
