GeForce GT 320 vs GeForce GTX 650 Ti

Intro

Compare all of that to the GeForce GTX 650 Ti, which features clock speeds of 928 MHz on the GPU, and 1350 MHz on the 1024 MB of GDDR5 RAM. It features 768 SPUs along with 64 Texture Address Units and 16 Rasterization Operator Units.

Power Usage and Theoretical Benchmarks

Power Consumption (Max TDP)

GeForce GT 320		43 Watts
GeForce GTX 650 Ti		110 Watts
	Difference: 67 Watts (156%)

Memory Bandwidth

Performance-wise, the GeForce GTX 650 Ti should in theory be quite a bit superior to the GeForce GT 320 in general. (explain)

GeForce GTX 650 Ti		86400 MB/sec
GeForce GT 320		25280 MB/sec
	Difference: 61120 (242%)

Texel Rate

The GeForce GTX 650 Ti should be quite a bit (approximately 358%) faster with regards to AF than the GeForce GT 320. (explain)

GeForce GTX 650 Ti		59392 Mtexels/sec
GeForce GT 320		12960 Mtexels/sec
	Difference: 46432 (358%)

Pixel Rate

If using high levels of AA is important to you, then the GeForce GTX 650 Ti is a better choice, by far. (explain)

GeForce GTX 650 Ti		14848 Mpixels/sec
GeForce GT 320		4320 Mpixels/sec
	Difference: 10528 (244%)

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 (counted in megabytes per second) that can be transferred across the external memory interface in a second. It is calculated by multiplying the card's interface width by the speed of its memory. If the card has DDR type RAM, it must be multiplied by 2 once again. If DDR5, multiply by 4 instead. The higher the bandwidth is, the faster the card will be in general. It especially helps with anti-aliasing, HDR and high resolutions.

Texel Rate: Texel rate is the maximum amount of texture map elements (texels) that are applied in one second. This figure is calculated by multiplying the total 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 in one second.

Pixel Rate: Pixel rate is the maximum number of pixels the graphics card could possibly record to its 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 card's clock speed. ROPs (Raster Operations Pipelines - also sometimes called Render Output Units) are responsible for outputting the pixels (image) to the screen. The actual pixel fill 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 reach the maximum fill rate.
