VS

GeForce GT 430 (OEM) vs GeForce GT 440 3GB

Intro

The GeForce GT 430 (OEM) features a GPU clock speed of 700 MHz, and the 2048 MB of GDDR3 RAM runs at 900 MHz through a 128-bit bus. It also is comprised of 96 Stream Processors, 16 TAUs, and 4 ROPs.

Compare those specifications to the GeForce GT 440 3GB, which makes use of 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 TAUs and 24 ROPs.

Memory Bandwidth: Memory bandwidth is the largest amount of data (counted in MB per second) that can be transferred over the external memory interface in one second. It's worked out by multiplying the card's bus width by its memory speed. If it uses DDR memory, it should be multiplied by 2 again. If DDR5, multiply by 4 instead. The better the memory bandwidth, the better 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 are processed in one second. This figure is worked out 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 card will be at handling texture filtering (anisotropic filtering - AF). It is measured in millions of texels in one second.

Pixel Rate: Pixel rate is the maximum number of pixels that the graphics chip could possibly write to the local memory per second - measured in millions of pixels per second. The figure is calculated by multiplying the number of colour ROPs by the the core speed of the card. ROPs (Raster Operations Pipelines - also called Render Output Units) are responsible for filling the screen with pixels (the image). The actual pixel fill rate is also dependant on lots of 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.
