GeForce GTX 460 SE vs GeForce GTX 650 Ti

Intro

Compare those specs to the GeForce GTX 650 Ti, which has GPU core speed of 928 MHz, and 1024 MB of GDDR5 memory set to run at 1350 MHz through a 128-bit bus. It also is comprised of 768 SPUs, 64 Texture Address Units, and 16 Raster Operation Units.

Power Usage and Theoretical Benchmarks

Power Consumption (Max TDP)

GeForce GTX 650 Ti		110 Watts
GeForce GTX 460 SE		150 Watts
	Difference: 40 Watts (36%)

Memory Bandwidth

Theoretically speaking, the GeForce GTX 460 SE should be 26% quicker than the GeForce GTX 650 Ti overall, because of its higher bandwidth. (explain)

GeForce GTX 460 SE		108800 MB/sec
GeForce GTX 650 Ti		86400 MB/sec
	Difference: 22400 (26%)

Texel Rate

The GeForce GTX 650 Ti is quite a bit (more or less 90%) faster with regards to texture filtering than the GeForce GTX 460 SE. (explain)

GeForce GTX 650 Ti		59392 Mtexels/sec
GeForce GTX 460 SE		31200 Mtexels/sec
	Difference: 28192 (90%)

Pixel Rate

If running with lots of anti-aliasing is important to you, then the GeForce GTX 460 SE is the winner, and very much so. (explain)

GeForce GTX 460 SE		20800 Mpixels/sec
GeForce GTX 650 Ti		14848 Mpixels/sec
	Difference: 5952 (40%)

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 max amount of information (in units of megabytes per second) that can be transferred over the external memory interface within a second. It is calculated by multiplying the bus width by the speed of its memory. If it uses DDR type memory, it must be multiplied by 2 again. If DDR5, multiply by ANOTHER 2x. The higher the bandwidth is, the better 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 applied per second. This number is calculated by multiplying the total number of texture units of the card by the core clock speed of the chip. The better this number, the better the video card will be at texture filtering (anisotropic filtering - AF). It is measured in millions of texels per second.

Pixel Rate: Pixel rate is the maximum number of pixels the video card can possibly record to the local memory in one second - measured in millions of pixels per second. The figure is worked out by multiplying the amount of Raster Operations Pipelines by the the core clock speed. ROPs (Raster Operations Pipelines - sometimes also referred to as Render Output Units) are responsible for drawing the pixels (image) on the screen. The actual pixel output rate also depends on many other factors, most notably the memory bandwidth - the lower the bandwidth is, the lower the potential to reach the maximum fill rate.
