GeForce GT 440 3GB vs Radeon HD 3850 256MB

Intro

The GeForce GT 440 3GB uses a 40 nm design. nVidia has clocked the core frequency at 594 MHz. The GDDR3 memory is set to run at a speed of 900 MHz on this model. It features 144 SPUs as well as 24 TAUs and 24 Rasterization Operator Units.

Compare those specifications to the Radeon HD 3850 256MB, which comes with GPU core speed of 668 MHz, and 256 MB of GDDR3 RAM set to run at 828 MHz through a 256-bit bus. It also is made up of 320(64x5) SPUs, 16 TAUs, and 16 ROPs.

Memory Bandwidth: Bandwidth is the maximum amount of information (counted in megabytes per second) that can be moved over the external memory interface in one second. The number is worked out by multiplying the card's bus width by the speed of its memory. If the card has DDR type RAM, it must be multiplied by 2 once 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 higher screen resolutions.

Texel Rate: Texel rate is the maximum amount of texture map elements (texels) that are applied per second. This is calculated by multiplying the total texture units by the core clock speed of the chip. The higher the texel rate, the better the graphics card will be at handling texture filtering (anisotropic filtering - AF). It is measured in millions of texels in a second.

Pixel Rate: Pixel rate is the maximum amount of pixels the video card could possibly record to the local memory in a second - measured in millions of pixels per second. The number is calculated by multiplying the number of Raster Operations Pipelines by the the core speed of the card. ROPs (Raster Operations Pipelines - aka Render Output Units) are responsible for drawing the pixels (image) on the screen. The actual pixel rate is also dependant on quite a few other factors, especially the memory bandwidth of the card - the lower the memory bandwidth is, the lower the ability to reach the maximum fill rate.
