GeForce GTX 460 vs GeForce GTX 650 Ti

Intro

Compare those specs to the GeForce GTX 650 Ti, which makes use of a 28 nm design. nVidia has set the core frequency at 928 MHz. The GDDR5 memory is set to run at a frequency of 1350 MHz on this model. It features 768 SPUs as well as 64 Texture Address Units and 16 ROPs.

3DMark Fire Strike Graphics Score

GeForce GTX 650 Ti		3434 points
GeForce GTX 460		2557 points
	Difference: 877 (34%)

Power Usage and Theoretical Benchmarks

Power Consumption (Max TDP)

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

Memory Bandwidth

Both cards have the exact same memory bandwidth, so theoretically they should perform exactly the same. (explain)

Texel Rate

The GeForce GTX 650 Ti is quite a bit (more or less 57%) faster with regards to AF than the GeForce GTX 460. (explain)

GeForce GTX 650 Ti		59392 Mtexels/sec
GeForce GTX 460		37800 Mtexels/sec
	Difference: 21592 (57%)

Pixel Rate

If using high levels of AA is important to you, then the GeForce GTX 460 is the winner, but it probably won't make a huge difference. (explain)

GeForce GTX 460		16200 Mpixels/sec
GeForce GTX 650 Ti		14848 Mpixels/sec
	Difference: 1352 (9%)

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 largest amount of data (in units of MB per second) that can be moved past the external memory interface within a second. The number is worked out by multiplying the bus width by its memory speed. In the case of DDR type memory, the result should be multiplied by 2 again. If DDR5, multiply by ANOTHER 2x. The higher the card's memory bandwidth, the better the card will be in general. It especially helps with AA, HDR and high resolutions.

Texel Rate: Texel rate is the maximum texture map elements (texels) that can be applied per second. This figure is calculated by multiplying the total texture units by the core clock speed of the chip. The higher the texel rate, the better the card will be at handling 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 the video card can possibly write to its local memory in one second - measured in millions of pixels per second. The number is worked out by multiplying the amount of Raster Operations Pipelines by the the core clock speed. ROPs (Raster Operations Pipelines - also called Render Output Units) are responsible for outputting the pixels (image) to the screen. The actual pixel rate is also dependant on lots of other factors, especially the memory bandwidth - the lower the memory bandwidth is, the lower the potential to get to the max fill rate.
