GeForce GTX 460 SE vs GeForce GTX Titan

Intro

Compare those specs to the GeForce GTX Titan, which makes use of a 28 nm design. nVidia has clocked the core frequency at 837 MHz. The GDDR5 memory runs at a speed of 1502 MHz on this card. It features 2688 SPUs as well as 224 TAUs and 48 Rasterization Operator Units.

Power Usage and Theoretical Benchmarks

Power Consumption (Max TDP)

GeForce GTX 460 SE		150 Watts
GeForce GTX Titan		250 Watts
	Difference: 100 Watts (67%)

Memory Bandwidth

As far as performance goes, the GeForce GTX Titan should in theory be a lot better than the GeForce GTX 460 SE overall. (explain)

GeForce GTX Titan		288384 MB/sec
GeForce GTX 460 SE		108800 MB/sec
	Difference: 179584 (165%)

Texel Rate

The GeForce GTX Titan should be quite a bit (about 501%) more effective at anisotropic filtering than the GeForce GTX 460 SE. (explain)

GeForce GTX Titan		187488 Mtexels/sec
GeForce GTX 460 SE		31200 Mtexels/sec
	Difference: 156288 (501%)

Pixel Rate

If using high levels of AA is important to you, then the GeForce GTX Titan is superior to the GeForce GTX 460 SE, by a large margin. (explain)

GeForce GTX Titan		40176 Mpixels/sec
GeForce GTX 460 SE		20800 Mpixels/sec
	Difference: 19376 (93%)

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 megabytes per second) that can be transported over the external memory interface in a second. It's worked out by multiplying the card's bus width by the speed of its memory. In the case of DDR memory, it should be multiplied by 2 once again. If it uses 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 texture map elements (texels) that are applied in one second. This is worked out by multiplying the total texture units by the core speed of the chip. The higher the texel rate, the better the graphics card will be at handling texture filtering (anisotropic filtering - AF). It is measured in millions of texels applied in one second.

Pixel Rate: Pixel rate is the most pixels the video card could possibly record to the local memory per second - measured in millions of pixels per second. Pixel rate is calculated by multiplying the number of ROPs by the the core clock speed. ROPs (Raster Operations Pipelines - also sometimes called 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 of the card - the lower the bandwidth is, the lower the potential to reach the maximum fill rate.
