Radeon HD 4830 512MB vs Radeon HD 6450 (OEM)

Intro

The Radeon HD 4830 512MB makes use of a 55 nm design. AMD has clocked the core speed at 575 MHz. The GDDR3 RAM is set to run at a speed of 900 MHz on this particular model. It features 640(128x5) SPUs along with 32 Texture Address Units and 16 Rasterization Operator Units.

Compare all that to the Radeon HD 6450 (OEM), which features GPU core speed of 625 MHz, and 512 MB of GDDR3 RAM set to run at 800 MHz through a 64-bit bus. It also is comprised of 160 Stream Processors, 8 TAUs, and 4 Raster Operation Units.

Memory Bandwidth: Memory bandwidth is the largest amount of information (measured in MB per second) that can be transferred past the external memory interface in one second. It's worked out by multiplying the card's interface width by its memory speed. In the case of DDR memory, it should be multiplied by 2 again. If it uses DDR5, multiply by ANOTHER 2x. The better the card's memory bandwidth, the faster 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 are processed per second. This is calculated by multiplying the total amount of texture units of the card by the core 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 the graphics card can possibly record to its local memory per second - measured in millions of pixels per second. Pixel rate is worked out by multiplying the amount of ROPs by the the core speed of the card. ROPs (Raster Operations Pipelines - also called Render Output Units) are responsible for outputting the pixels (image) to the screen. The actual pixel rate also depends on many other factors, especially the memory bandwidth of the card - the lower the bandwidth is, the lower the potential to get to the maximum fill rate.
