GeForce GTX 580 3GB vs GeForce GTX Titan Black

Intro

Compare that to the GeForce GTX Titan Black, which uses a 28 nm design. nVidia has set the core speed at 889 MHz. The GDDR5 memory is set to run at a frequency of 1750 MHz on this model. It features 2880 SPUs along with 240 Texture Address Units and 48 Rasterization Operator Units.

Power Usage and Theoretical Benchmarks

Power Consumption (Max TDP)

GeForce GTX 580 3GB		244 Watts
GeForce GTX Titan Black		250 Watts
	Difference: 6 Watts (2%)

Memory Bandwidth

Theoretically speaking, the GeForce GTX Titan Black should be 75% quicker than the GeForce GTX 580 3GB in general, because of its greater data rate. (explain)

GeForce GTX Titan Black		336000 MB/sec
GeForce GTX 580 3GB		192384 MB/sec
	Difference: 143616 (75%)

Texel Rate

The GeForce GTX Titan Black is quite a bit (about 332%) more effective at AF than the GeForce GTX 580 3GB. (explain)

GeForce GTX Titan Black		213360 Mtexels/sec
GeForce GTX 580 3GB		49408 Mtexels/sec
	Difference: 163952 (332%)

Pixel Rate

The GeForce GTX Titan Black should be a bit (more or less 15%) more effective at AA than the GeForce GTX 580 3GB, and also should be able to handle higher resolutions without slowing down too much. (explain)

GeForce GTX Titan Black		42672 Mpixels/sec
GeForce GTX 580 3GB		37056 Mpixels/sec
	Difference: 5616 (15%)

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 maximum amount of data (in units of MB per second) that can be transported across the external memory interface in one second. It is worked out by multiplying the card's bus width by its memory speed. If the card has DDR memory, it must be multiplied by 2 again. If DDR5, multiply by ANOTHER 2x. The higher the memory bandwidth, the faster the card will be in general. It especially helps with anti-aliasing, HDR and higher screen resolutions.

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