GeForce GT 320 vs GeForce GTX 280

Intro

Compare those specs to the GeForce GTX 280, which features GPU core speed of 602 MHz, and 1024 MB of GDDR3 memory running at 1107 MHz through a 512-bit bus. It also features 240 SPUs, 80 Texture Address Units, and 32 ROPs.

Power Usage and Theoretical Benchmarks

Power Consumption (Max TDP)

GeForce GT 320		43 Watts
GeForce GTX 280		236 Watts
	Difference: 193 Watts (449%)

Memory Bandwidth

Theoretically, the GeForce GTX 280 should be quite a bit faster than the GeForce GT 320 overall. (explain)

GeForce GTX 280		141696 MB/sec
GeForce GT 320		25280 MB/sec
	Difference: 116416 (461%)

Texel Rate

The GeForce GTX 280 should be quite a bit (about 272%) faster with regards to texture filtering than the GeForce GT 320. (explain)

GeForce GTX 280		48160 Mtexels/sec
GeForce GT 320		12960 Mtexels/sec
	Difference: 35200 (272%)

Pixel Rate

If using lots of anti-aliasing is important to you, then the GeForce GTX 280 is a better choice, by far. (explain)

GeForce GTX 280		19264 Mpixels/sec
GeForce GT 320		4320 Mpixels/sec
	Difference: 14944 (346%)

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: Bandwidth is the largest amount of data (measured in MB per second) that can be transported across the external memory interface in a second. It is calculated by multiplying the card's interface width by its memory speed. If it uses DDR type RAM, it should be multiplied by 2 once again. If it uses DDR5, multiply by ANOTHER 2x. The better the memory bandwidth, 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 texture map elements (texels) that are applied per second. This is calculated by multiplying the total amount of texture units by the core clock speed of the chip. The better the texel rate, the better the 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 number of pixels the graphics 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 amount of colour ROPs by the the core speed of the card. ROPs (Raster Operations Pipelines - sometimes also referred to as Render Output Units) are responsible for outputting the pixels (image) to the screen. The actual pixel rate also depends on quite a few other factors, most notably the memory bandwidth - the lower the bandwidth is, the lower the ability to get to the maximum fill rate.
