GeForce GT 430 vs GeForce GTX 460 2GB

Intro

Compare that to the GeForce GTX 460 2GB, which makes use of a 40 nm design. nVidia has clocked the core frequency at 675 MHz. The GDDR5 memory is set to run at a frequency of 900 MHz on this specific model. It features 336 SPUs along with 56 TAUs and 32 Rasterization Operator Units.

GeForce GT 430		28800 MB/sec
	Difference: 86400 (300%)

Texel Rate

The GeForce GTX 460 2GB is much (about 238%) more effective at texture filtering than the GeForce GT 430. (explain)

GeForce GTX 460 2GB		37800 Mtexels/sec
GeForce GT 430		11200 Mtexels/sec
	Difference: 26600 (238%)

Pixel Rate

The GeForce GTX 460 2GB will be quite a bit (more or less 671%) better at full screen anti-aliasing than the GeForce GT 430, and also should be capable of handling higher screen resolutions without slowing down too much. (explain)

GeForce GTX 460 2GB		21600 Mpixels/sec
GeForce GT 430		2800 Mpixels/sec
	Difference: 18800 (671%)

Please note that the above 'benchmarks' are all just theoretical - the results were calculated based on the card's specifications, and real-world performance may (and probably will) vary at least a bit.

Specifications

Memory Bandwidth: Memory bandwidth is the largest amount of information (in units of MB per second) that can be transferred across the external memory interface in one second. It is worked out by multiplying the bus width by its memory speed. If the card has DDR memory, it must be multiplied by 2 again. If DDR5, multiply by 4 instead. The higher the memory bandwidth, the faster the card will be in general. It especially helps with AA, High Dynamic Range and high resolutions.

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

Pixel Rate: Pixel rate is the most pixels the video card can possibly write to the local memory in a second - measured in millions of pixels per second. Pixel rate is calculated by multiplying the number of Raster Operations Pipelines by the the card's clock speed. 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 also depends on many other factors, especially the memory bandwidth of the card - the lower the bandwidth is, the lower the potential to get to the max fill rate.
