GeForce GT 320 vs Geforce GTX 760

Intro

Compare all that to the Geforce GTX 760, which has a clock speed of 980 MHz and a GDDR5 memory frequency of 1502 MHz. It also uses a 256-bit bus, and makes use of a 28 nm design. It is made up of 1152 SPUs, 96 TAUs, and 32 ROPs.

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 is 661% faster than the GeForce GT 320 overall, due to its greater data rate. (explain)

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

Texel Rate

The Geforce GTX 760 is much (approximately 626%) faster with regards to texture filtering than the GeForce GT 320. (explain)

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

Pixel Rate

The Geforce GTX 760 should be quite a bit (about 626%) more effective at anti-aliasing than the GeForce GT 320, and will be able to handle higher screen resolutions more effectively. (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 max amount of data (counted in megabytes per second) that can be transferred over the external memory interface within a second. It is calculated by multiplying the interface width by its memory clock speed. In the case of DDR type memory, it must be multiplied by 2 once again. If DDR5, multiply by 4 instead. The better the card's memory bandwidth, the better the card will be in general. It especially helps with AA, High Dynamic Range and high resolutions.

Texel Rate: Texel rate is the maximum number of texture map elements (texels) that are processed in one second. This is calculated by multiplying the total texture units by the core speed of the chip. The better the texel rate, the better the video card will be at 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 can possibly record to the local memory in one second - measured in millions of pixels per second. The number is worked out by multiplying the number of Raster Operations Pipelines by the clock speed of the card. ROPs (Raster Operations Pipelines - aka Render Output Units) are responsible for drawing the pixels (image) on the screen. The actual pixel rate also depends on lots of other factors, especially the memory bandwidth of the card - the lower the bandwidth is, the lower the ability to reach the max fill rate.
