GeForce GT 440 3GB vs Radeon HD 4670 1GB

Intro

The GeForce GT 440 3GB uses a 40 nm design. nVidia has set the core frequency at 594 MHz. The GDDR3 RAM is set to run at a speed of 900 MHz on this particular card. It features 144 SPUs along with 24 Texture Address Units and 24 ROPs.

Compare that to the Radeon HD 4670 1GB, which uses a 55 nm design. AMD has clocked the core speed at 750 MHz. The GDDR4/GDDR3/DDR3/DDR2 memory is set to run at a speed of 1100 MHz on this specific model. It features 320(64x5) SPUs along with 32 TAUs and 8 Rasterization Operator Units.

Memory Bandwidth: Memory bandwidth is the max amount of information (counted in MB per second) that can be transported over the external memory interface in one second. It's calculated by multiplying the card's bus width by its memory clock speed. If it uses DDR type RAM, it should be multiplied by 2 again. If 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 higher screen resolutions.

Texel Rate: Texel rate is the maximum number of texture map elements (texels) that are processed per second. This number is calculated by multiplying the total amount of texture units of the card by the core speed of the chip. The better this number, the better the video 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 maximum number of pixels that the graphics card can possibly write to its local memory in a second - measured in millions of pixels per second. The number is worked out by multiplying the amount of colour ROPs by the the core speed of the card. ROPs (Raster Operations Pipelines - also sometimes called Render Output Units) are responsible for filling the screen with pixels (the image). The actual pixel fill rate is also dependant on quite a few other factors, most notably the memory bandwidth of the card - the lower the bandwidth is, the lower the ability to get to the maximum fill rate.
