GeForce GT 320 vs GeForce GTX 260 Core 216

Intro

Compare those specs to the GeForce GTX 260 Core 216, which has GPU core speed of 576 MHz, and 896 MB of GDDR3 RAM running at 999 MHz through a 448-bit bus. It also is comprised of 216 SPUs, 72 TAUs, and 28 Raster Operation Units.

GeForce GT 320		25280 MB/sec
	Difference: 86608 (343%)

Texel Rate

The GeForce GTX 260 Core 216 should be a lot (approximately 220%) more effective at AF than the GeForce GT 320. (explain)

GeForce GTX 260 Core 216		41472 Mtexels/sec
GeForce GT 320		12960 Mtexels/sec
	Difference: 28512 (220%)

Pixel Rate

The GeForce GTX 260 Core 216 should be quite a bit (about 273%) faster with regards to full screen anti-aliasing than the GeForce GT 320, and capable of handling higher resolutions without losing too much performance. (explain)

GeForce GTX 260 Core 216		16128 Mpixels/sec
GeForce GT 320		4320 Mpixels/sec
	Difference: 11808 (273%)

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 max amount of information (in units of megabytes per second) that can be moved over the external memory interface in a second. It is worked out by multiplying the interface width by the speed of its memory. If it uses DDR type memory, it must 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 texture map elements (texels) that are applied in one second. This number is worked out by multiplying the total number of texture units of the card by the core clock speed of the chip. The better the texel rate, the better the card will be at texture filtering (anisotropic filtering - AF). It is measured in millions of texels in a second.

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