GeForce GT 320 vs GeForce GTX 980

Intro

Compare all of that to the GeForce GTX 980, which has GPU core speed of 1126 MHz, and 4096 MB of GDDR5 RAM running at 1750 MHz through a 256-bit bus. It also is comprised of 2048 Stream Processors, 128 TAUs, and 64 Raster Operation Units.

Power Usage and Theoretical Benchmarks

Power Consumption (Max TDP)

GeForce GT 320		43 Watts
GeForce GTX 980		165 Watts
	Difference: 122 Watts (284%)

Memory Bandwidth

The GeForce GTX 980 should theoretically perform a lot faster than the GeForce GT 320 overall. (explain)

GeForce GTX 980		224000 MB/sec
GeForce GT 320		25280 MB/sec
	Difference: 198720 (786%)

Texel Rate

The GeForce GTX 980 should be quite a bit (more or less 1012%) better at AF than the GeForce GT 320. (explain)

GeForce GTX 980		144128 Mtexels/sec
GeForce GT 320		12960 Mtexels/sec
	Difference: 131168 (1012%)

Pixel Rate

If running with a high resolution is important to you, then the GeForce GTX 980 is superior to the GeForce GT 320, and very much so. (explain)

GeForce GTX 980		72064 Mpixels/sec
GeForce GT 320		4320 Mpixels/sec
	Difference: 67744 (1568%)

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 data (counted in megabytes per second) that can be transported past the external memory interface within a second. The number is worked out by multiplying the card's bus width by its memory clock speed. In the case of DDR type RAM, it should be multiplied by 2 again. If it uses DDR5, multiply by 4 instead. The better the card's memory bandwidth, the better the card will be in general. It especially helps with anti-aliasing, HDR and higher screen resolutions.

Texel Rate: Texel rate is the maximum amount of texture map elements (texels) that can be processed per second. This figure is calculated by multiplying the total number of texture units by the core speed of the chip. The better the texel rate, the better the video 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 that the graphics card could possibly write to its local memory per second - measured in millions of pixels per second. The figure is calculated by multiplying the amount of colour ROPs by the the core 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 rate also depends on many other factors, especially the memory bandwidth - the lower the bandwidth is, the lower the potential to reach the max fill rate.
