GeForce GT 320 vs GeForce GTX 460 SE

Intro

Compare those specifications to the GeForce GTX 460 SE, which has core clock speeds of 650 MHz on the GPU, and 850 MHz on the 1024 MB of GDDR5 RAM. It features 288 SPUs along with 48 Texture Address Units and 32 Rasterization Operator Units.

Texel Rate

The GeForce GTX 460 SE should be a lot (approximately 141%) better at anisotropic filtering than the GeForce GT 320. (explain)

GeForce GTX 460 SE		31200 Mtexels/sec
GeForce GT 320		12960 Mtexels/sec
	Difference: 18240 (141%)

Pixel Rate

The GeForce GTX 460 SE should be quite a bit (more or less 381%) faster with regards to anti-aliasing than the GeForce GT 320, and also able to handle higher resolutions more effectively. (explain)

GeForce GTX 460 SE		20800 Mpixels/sec
GeForce GT 320		4320 Mpixels/sec
	Difference: 16480 (381%)

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 max amount of data (in units of megabytes per second) that can be transported over the external memory interface within a second. It is worked out by multiplying the card's bus width by its memory clock speed. In the case of DDR memory, it must be multiplied by 2 once again. If it uses DDR5, multiply by 4 instead. The higher the bandwidth is, the better the card will be in general. It especially helps with anti-aliasing, High Dynamic Range and high resolutions.

Texel Rate: Texel rate is the maximum amount of texture map elements (texels) that are processed per second. This number is worked out by multiplying the total texture units of the card by the core 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 applied per second.

Pixel Rate: Pixel rate is the maximum amount of pixels that the graphics card can possibly write to its local memory per second - measured in millions of pixels per second. Pixel rate is calculated by multiplying the number of colour ROPs 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 fill rate also depends on lots of other factors, especially the memory bandwidth of the card - the lower the bandwidth is, the lower the potential to reach the max fill rate.
