GeForce GT 320 vs GeForce GTX 750 Ti

Intro

Compare all that to the GeForce GTX 750 Ti, which features core clock speeds of 1020 MHz on the GPU, and 1350 MHz on the 2048 MB of GDDR5 RAM. It features 640 SPUs along with 40 Texture Address Units and 16 Rasterization Operator Units.

GeForce GT 320		25280 MB/sec
	Difference: 61120 (242%)

Texel Rate

The GeForce GTX 750 Ti will be quite a bit (more or less 215%) better at anisotropic filtering than the GeForce GT 320. (explain)

GeForce GTX 750 Ti		40800 Mtexels/sec
GeForce GT 320		12960 Mtexels/sec
	Difference: 27840 (215%)

Pixel Rate

If using a high screen resolution is important to you, then the GeForce GTX 750 Ti is a better choice, by a large margin. (explain)

GeForce GTX 750 Ti		16320 Mpixels/sec
GeForce GT 320		4320 Mpixels/sec
	Difference: 12000 (278%)

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 (counted in megabytes per second) that can be moved over the external memory interface in a second. It is worked out by multiplying the bus width by its memory clock speed. In the case of DDR type memory, it must be multiplied by 2 once again. If it uses DDR5, multiply by ANOTHER 2x. The better the card's memory bandwidth, the faster the card will be in general. It especially helps with AA, High Dynamic Range and higher screen resolutions.

Texel Rate: Texel rate is the maximum amount of texture map elements (texels) that can be applied in one second. This figure is worked out by multiplying the total texture units 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 per second.

Pixel Rate: Pixel rate is the most pixels the video card could possibly record to the local memory in a second - measured in millions of pixels per second. The number is calculated by multiplying the number of ROPs by the the core clock speed. ROPs (Raster Operations Pipelines - aka Render Output Units) are responsible for outputting the pixels (image) to the screen. The actual pixel fill rate is also dependant on lots of other factors, especially the memory bandwidth - the lower the bandwidth is, the lower the potential to reach the max fill rate.
