GeForce GT 440 1.5GB vs Radeon HD 6750

Intro

The GeForce GT 440 1.5GB comes with a clock speed of 594 MHz and a GDDR3 memory speed of 900 MHz. It also features a 192-bit memory bus, and uses a 40 nm design. It is comprised of 144 SPUs, 24 TAUs, and 24 ROPs.

Compare those specs to the Radeon HD 6750, which makes use of a 40 nm design. AMD has set the core speed at 725 MHz. The GDDR5 memory works at a speed of 1000 MHz on this specific card. It features 720 SPUs as well as 36 Texture Address Units and 16 ROPs.

Memory Bandwidth: Bandwidth is the maximum amount of data (in units of megabytes per second) that can be transported across the external memory interface in one second. It's worked out by multiplying the interface width by its memory clock speed. In the case of DDR type memory, it must be multiplied by 2 again. If it uses DDR5, multiply by ANOTHER 2x. The higher the card's memory bandwidth, the faster the card will be in general. It especially helps with anti-aliasing, High Dynamic Range and higher screen resolutions.

Texel Rate: Texel rate is the maximum number of texture map elements (texels) that can be processed in one second. This is worked out by multiplying the total number of texture units by the core clock speed of the chip. The higher this number, the better the card will be at handling texture filtering (anisotropic filtering - AF). It is measured in millions of texels applied per second.

Pixel Rate: Pixel rate is the most pixels the graphics card could possibly write to its local memory in one second - measured in millions of pixels per second. The figure is calculated by multiplying the number of ROPs by the the card's clock speed. ROPs (Raster Operations Pipelines - also sometimes called Render Output Units) are responsible for filling the screen with pixels (the image). The actual pixel output rate also depends on quite a few other factors, especially the memory bandwidth of the card - the lower the memory bandwidth is, the lower the potential to get to the max fill rate.
