GeForce GTX 460 vs GeForce GTX 650 Ti 2GB

Intro

Compare those specifications to the GeForce GTX 650 Ti 2GB, which comes with a clock speed of 928 MHz and a GDDR5 memory frequency 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 2GB		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 2GB will be a lot (approximately 57%) more effective at texture filtering than the GeForce GTX 460. (explain)

GeForce GTX 650 Ti 2GB		59392 Mtexels/sec
GeForce GTX 460		37800 Mtexels/sec
	Difference: 21592 (57%)

Pixel Rate

The GeForce GTX 460 will be a bit (approximately 9%) more effective at AA than the GeForce GTX 650 Ti 2GB, and also able to handle higher resolutions without losing too much performance. (explain)

GeForce GTX 460		16200 Mpixels/sec
GeForce GTX 650 Ti 2GB		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 max amount of data (in units of MB per second) that can be transferred past the external memory interface within a second. It is calculated by multiplying the card's bus width by the speed of its memory. In the case of DDR RAM, it must be multiplied by 2 once again. If DDR5, multiply by ANOTHER 2x. The better the card's memory bandwidth, the better 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 amount of texture map elements (texels) that can be applied per second. This is calculated by multiplying the total amount of texture units by the core speed of the chip. The better the texel rate, 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 amount of pixels that the graphics chip can possibly write to its local memory per second - measured in millions of pixels per second. The number is calculated by multiplying the amount of Render Output Units by the the card's clock speed. ROPs (Raster Operations Pipelines - aka Render Output Units) are responsible for filling the screen with pixels (the image). The actual pixel fill rate also depends on lots of other factors, most notably the memory bandwidth - the lower the memory bandwidth is, the lower the potential to reach the maximum fill rate.
