GeForce GTX 260 Core 216 vs GeForce GTX Titan Black

Intro

Compare all of that to the GeForce GTX Titan Black, which has a GPU core clock speed of 889 MHz, and 6144 MB of GDDR5 memory set to run at 1750 MHz through a 384-bit bus. It also is comprised of 2880 SPUs, 240 TAUs, and 48 Raster Operation Units.

GeForce GTX 260 Core 216		202 Watts
GeForce GTX Titan Black		250 Watts
	Difference: 48 Watts (24%)

Memory Bandwidth

Theoretically speaking, the GeForce GTX Titan Black should be 200% faster than the GeForce GTX 260 Core 216 overall, due to its higher bandwidth. (explain)

GeForce GTX Titan Black		336000 MB/sec
GeForce GTX 260 Core 216		111888 MB/sec
	Difference: 224112 (200%)

Texel Rate

The GeForce GTX Titan Black is much (about 414%) more effective at AF than the GeForce GTX 260 Core 216. (explain)

GeForce GTX Titan Black		213360 Mtexels/sec
GeForce GTX 260 Core 216		41472 Mtexels/sec
	Difference: 171888 (414%)

Pixel Rate

The GeForce GTX Titan Black is a lot (more or less 165%) more effective at full screen anti-aliasing than the GeForce GTX 260 Core 216, and should be capable of handling higher resolutions without slowing down too much. (explain)

GeForce GTX Titan Black		42672 Mpixels/sec
GeForce GTX 260 Core 216		16128 Mpixels/sec
	Difference: 26544 (165%)

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 (measured in megabytes per second) that can be moved past the external memory interface in a second. It's calculated by multiplying the card's bus width by the speed of its memory. If it uses DDR memory, it should be multiplied by 2 again. If it uses DDR5, multiply by ANOTHER 2x. The higher the card's memory bandwidth, the faster the card will be in general. It especially helps with AA, HDR and higher screen resolutions.

Texel Rate: Texel rate is the maximum amount 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 better this number, the better the graphics 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 that the graphics card can possibly write to the local memory per second - measured in millions of pixels per second. The number is calculated by multiplying the amount of ROPs by the the core speed of the card. ROPs (Raster Operations Pipelines - sometimes also referred to as Render Output Units) are responsible for filling the screen with pixels (the image). The actual pixel output rate also depends on quite a few other factors, especially the memory bandwidth - the lower the memory bandwidth is, the lower the ability to reach the maximum fill rate.
