GeForce GTX 460 2GB vs GeForce GTX Titan

Intro

Compare all that to the GeForce GTX Titan, which has GPU core speed of 837 MHz, and 6144 MB of GDDR5 memory set to run at 1502 MHz through a 384-bit bus. It also is comprised of 2688 Stream Processors, 224 Texture Address Units, and 48 Raster Operation Units.

Power Usage and Theoretical Benchmarks

Power Consumption (Max TDP)

GeForce GTX 460 2GB		160 Watts
GeForce GTX Titan		250 Watts
	Difference: 90 Watts (56%)

Memory Bandwidth

Theoretically speaking, the GeForce GTX Titan should be 150% faster than the GeForce GTX 460 2GB in general, because of its greater bandwidth. (explain)

GeForce GTX Titan		288384 MB/sec
GeForce GTX 460 2GB		115200 MB/sec
	Difference: 173184 (150%)

Texel Rate

The GeForce GTX Titan should be a lot (more or less 396%) better at anisotropic filtering than the GeForce GTX 460 2GB. (explain)

GeForce GTX Titan		187488 Mtexels/sec
GeForce GTX 460 2GB		37800 Mtexels/sec
	Difference: 149688 (396%)

Pixel Rate

The GeForce GTX Titan will be a lot (approximately 86%) better at AA than the GeForce GTX 460 2GB, and also should be able to handle higher screen resolutions more effectively. (explain)

GeForce GTX Titan		40176 Mpixels/sec
GeForce GTX 460 2GB		21600 Mpixels/sec
	Difference: 18576 (86%)

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 (measured in megabytes per second) that can be transferred over the external memory interface in a second. It is calculated by multiplying the bus width by its memory speed. If it uses DDR RAM, the result should be multiplied by 2 once again. If it uses DDR5, multiply by 4 instead. The better the 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 are processed in one second. This figure is worked out by multiplying the total number of texture units of the card by the core clock speed of the chip. The higher this number, the better the video card will be at texture filtering (anisotropic filtering - AF). It is measured in millions of texels processed per second.

Pixel Rate: Pixel rate is the maximum amount of pixels that the graphics card can possibly write to the local memory in a second - measured in millions of pixels per second. The figure 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 outputting the pixels (image) to the screen. The actual pixel fill rate is also dependant on lots of other factors, especially the memory bandwidth of the card - the lower the bandwidth is, the lower the potential to reach the maximum fill rate.
