GeForce GT 440 3GB vs Radeon HD 4770

Intro

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

Compare those specs to the Radeon HD 4770, which has a GPU core clock speed of 750 MHz, and 512 MB of GDDR5 memory set to run at 800 MHz through a 128-bit bus. It also is comprised of 640(128x5) Stream Processors, 32 TAUs, and 16 Raster Operation Units.

Memory Bandwidth: Memory bandwidth is the maximum amount of data (in units of megabytes per second) that can be moved across the external memory interface in one second. The number is calculated by multiplying the interface width by its memory speed. If it uses DDR type memory, the result should be multiplied by 2 once again. If it uses DDR5, multiply by 4 instead. The higher 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 per second. This is worked out 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 per second.

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