GeForce GT 320 vs Geforce GTX 760

Intro

Compare those specifications to the Geforce GTX 760, which uses a 28 nm design. nVidia has set the core speed at 980 MHz. The GDDR5 RAM works at a speed of 1502 MHz on this card. It features 1152 SPUs as well as 96 Texture Address Units and 32 Rasterization Operator Units.

Power Usage and Theoretical Benchmarks

Power Consumption (Max TDP)

GeForce GT 320		43 Watts
Geforce GTX 760		170 Watts
	Difference: 127 Watts (295%)

Memory Bandwidth

Theoretically speaking, the Geforce GTX 760 should perform much faster than the GeForce GT 320 in general. (explain)

Geforce GTX 760		192256 MB/sec
GeForce GT 320		25280 MB/sec
	Difference: 166976 (661%)

Texel Rate

The Geforce GTX 760 will be a lot (more or less 626%) faster with regards to anisotropic filtering than the GeForce GT 320. (explain)

Geforce GTX 760		94080 Mtexels/sec
GeForce GT 320		12960 Mtexels/sec
	Difference: 81120 (626%)

Pixel Rate

If running with a high screen resolution is important to you, then the Geforce GTX 760 is the winner, by far. (explain)

Geforce GTX 760		31360 Mpixels/sec
GeForce GT 320		4320 Mpixels/sec
	Difference: 27040 (626%)

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 maximum amount of data (counted in megabytes per second) that can be transferred over the external memory interface in a second. It's calculated by multiplying the card's bus width by its memory speed. If it uses DDR memory, it must be multiplied by 2 once again. If it uses DDR5, multiply by ANOTHER 2x. The higher the bandwidth is, the better the card will be in general. It especially helps with AA, HDR and higher screen resolutions.

Texel Rate: Texel rate is the maximum number of texture map elements (texels) that can be processed 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 higher the texel rate, the better the video card will be at texture filtering (anisotropic filtering - AF). It is measured in millions of texels applied in a second.

Pixel Rate: Pixel rate is the maximum amount of pixels the video card could possibly write to its local memory in a second - measured in millions of pixels per second. Pixel rate is calculated by multiplying the amount of Render Output Units by the the core speed of the card. ROPs (Raster Operations Pipelines - sometimes also referred to as Render Output Units) are responsible for drawing the pixels (image) on the screen. The actual pixel rate is also dependant on lots of other factors, most notably the memory bandwidth - the lower the bandwidth is, the lower the potential to reach the maximum fill rate.
