GeForce GTX 460 vs GeForce GTX 650 Ti

Intro

Compare those specs to the GeForce GTX 650 Ti, which features a core clock speed of 928 MHz and a GDDR5 memory speed of 1350 MHz. It also uses a 128-bit bus, and uses a 28 nm design. It is made up of 768 SPUs, 64 Texture Address Units, and 16 ROPs.

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 exactly the same bandwidth, so in theory they should have identical performance. (explain)

Texel Rate

The GeForce GTX 650 Ti will be much (more or less 57%) more effective at 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

The GeForce GTX 460 should be just a bit (about 9%) better at full screen anti-aliasing than the GeForce GTX 650 Ti, and should be able to handle higher resolutions without slowing down too much. (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 max amount of data (measured in megabytes per second) that can be transferred across the external memory interface in a second. It is calculated by multiplying the card's bus width by its memory clock speed. In the case of DDR type memory, the result should be multiplied by 2 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 AA, HDR and high resolutions.

Texel Rate: Texel rate is the maximum amount of texture map elements (texels) that are processed in one second. This figure is calculated by multiplying the total number of texture units by the core 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 applied in one second.

Pixel Rate: Pixel rate is the maximum number of pixels that the graphics card can possibly record to its local memory per second - measured in millions of pixels per second. The number is worked out by multiplying the number of Raster Operations Pipelines 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 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.
