Radeon HD 4730 vs Radeon HD 5670

Intro

The Radeon HD 4730 has a GPU core speed of 700 MHz, and the 512 MB of GDDR5 memory runs at 900 MHz through a 128-bit bus. It also is comprised of 640(128x5) SPUs, 32 TAUs, and 8 ROPs.

Compare those specifications to the Radeon HD 5670, which makes use of a 40 nm design. AMD has clocked the core speed at 775 MHz. The GDDR5 memory works at a frequency of 1000 MHz on this particular card. It features 400(80x5) SPUs along with 20 TAUs and 8 Rasterization Operator Units.

Memory Bandwidth: Memory bandwidth is the max amount of information (measured in MB per second) that can be moved over the external memory interface within a second. The number is worked out by multiplying the bus width by the speed of its memory. If the card has DDR RAM, it should be multiplied by 2 again. If it uses DDR5, multiply by ANOTHER 2x. 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 texture map elements (texels) that are applied in one second. This number is calculated by multiplying the total number of texture units by the core clock speed of the chip. The better this number, the better the card will be at texture filtering (anisotropic filtering - AF). It is measured in millions of texels per second.

Pixel Rate: Pixel rate is the maximum amount of pixels that the graphics card can possibly write to its local memory in one second - measured in millions of pixels per second. The number is calculated by multiplying the amount of Raster Operations Pipelines by the the core speed of the card. ROPs (Raster Operations Pipelines - also called Render Output Units) are responsible for drawing the pixels (image) on the screen. The actual pixel rate also depends on lots of other factors, most notably the memory bandwidth - the lower the memory bandwidth is, the lower the potential to get to the maximum fill rate.
