GeForce GTX 580 3GB vs Geforce GTX 760

Intro

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

Power Usage and Theoretical Benchmarks

Power Consumption (Max TDP)

Geforce GTX 760		170 Watts
GeForce GTX 580 3GB		244 Watts
	Difference: 74 Watts (44%)

Memory Bandwidth

In theory, the GeForce GTX 580 3GB should be 0% faster than the Geforce GTX 760 overall, because of its greater bandwidth. (explain)

GeForce GTX 580 3GB		192384 MB/sec
Geforce GTX 760		192256 MB/sec
	Difference: 128 (0%)

Texel Rate

The Geforce GTX 760 is a lot (more or less 90%) more effective at anisotropic filtering than the GeForce GTX 580 3GB. (explain)

Geforce GTX 760		94080 Mtexels/sec
GeForce GTX 580 3GB		49408 Mtexels/sec
	Difference: 44672 (90%)

Pixel Rate

The GeForce GTX 580 3GB will be a small bit (approximately 18%) better at AA than the Geforce GTX 760, and also should be able to handle higher resolutions without slowing down too much. (explain)

GeForce GTX 580 3GB		37056 Mpixels/sec
Geforce GTX 760		31360 Mpixels/sec
	Difference: 5696 (18%)

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 MB per second) that can be transferred across the external memory interface in one second. It is calculated by multiplying the interface width by the speed of its memory. If it uses DDR memory, it must be multiplied by 2 again. If DDR5, multiply by 4 instead. The higher the card's memory bandwidth, the faster the card will be in general. It especially helps with anti-aliasing, High Dynamic Range and high 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 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 per second.

Pixel Rate: Pixel rate is the most pixels the graphics card can possibly record to its local memory in a second - measured in millions of pixels per second. The figure is calculated by multiplying the amount of colour ROPs by the clock speed of the card. ROPs (Raster Operations Pipelines - also called Render Output Units) are responsible for filling the screen with pixels (the image). The actual pixel fill rate is also dependant on many other factors, most notably the memory bandwidth - the lower the memory bandwidth is, the lower the potential to get to the maximum fill rate.
