GeForce GTX 460 vs GeForce GTX 650 Ti

Intro

Compare those specifications to the GeForce GTX 650 Ti, which has a core clock frequency of 928 MHz and a GDDR5 memory speed of 1350 MHz. It also makes use of a 128-bit memory bus, and makes use of a 28 nm design. It is made up of 768 SPUs, 64 TAUs, and 16 ROPs.

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

Memory Bandwidth

Both cards have the exact same bandwidth, so in theory they should have the same performance. (explain)

Texel Rate

The GeForce GTX 650 Ti will be much (about 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

If using high levels of AA is important to you, then the GeForce GTX 460 is the winner, but not by far. (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: Memory bandwidth is the maximum amount of information (measured in MB per second) that can be transferred past the external memory interface in a second. It's calculated by multiplying the card's bus width by the speed of its memory. In the case of DDR type RAM, it must be multiplied by 2 once again. If DDR5, multiply by 4 instead. The better the bandwidth is, the faster the card will be in general. It especially helps with AA, High Dynamic Range and higher screen resolutions.

Texel Rate: Texel rate is the maximum amount of texture map elements (texels) that are applied in one second. This number is worked out by multiplying the total texture units of the card by the core clock speed of the chip. The better the texel rate, the better the card will be at handling texture filtering (anisotropic filtering - AF). It is measured in millions of texels in a second.

Pixel Rate: Pixel rate is the most pixels the graphics card could possibly record to the local memory in a second - measured in millions of pixels per second. Pixel rate is worked out by multiplying the number of Render Output Units by the the core speed of the card. ROPs (Raster Operations Pipelines - also called Render Output Units) are responsible for drawing the pixels (image) on the screen. The actual pixel fill rate also depends on many other factors, most notably the memory bandwidth of the card - the lower the bandwidth is, the lower the ability to reach the maximum fill rate.
