GeForce GTX 460 1GB vs GeForce GTX 750 Ti

Intro

Compare all of that to the GeForce GTX 750 Ti, which has core clock speeds of 1020 MHz on the GPU, and 1350 MHz on the 2048 MB of GDDR5 memory. It features 640 SPUs along with 40 Texture Address Units and 16 Rasterization Operator Units.

GeForce GTX 750 Ti		86400 MB/sec
	Difference: 28800 (33%)

Texel Rate

The GeForce GTX 750 Ti will be a small bit (approximately 8%) faster with regards to anisotropic filtering than the GeForce GTX 460 1GB. (explain)

GeForce GTX 750 Ti		40800 Mtexels/sec
GeForce GTX 460 1GB		37800 Mtexels/sec
	Difference: 3000 (8%)

Pixel Rate

If using high levels of AA is important to you, then the GeForce GTX 460 1GB is the winner, by a large margin. (explain)

GeForce GTX 460 1GB		21600 Mpixels/sec
GeForce GTX 750 Ti		16320 Mpixels/sec
	Difference: 5280 (32%)

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

Texel Rate: Texel rate is the maximum amount of texture map elements (texels) that can be applied in one second. This is worked out by multiplying the total number of texture units by the core speed of the chip. The higher this number, the better the video 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 maximum number of pixels that the graphics chip could possibly record to the local memory in one second - measured in millions of pixels per second. Pixel rate is calculated by multiplying the number of Render Output Units by the the core speed of the card. ROPs (Raster Operations Pipelines - aka Render Output Units) are responsible for outputting the pixels (image) to the screen. The actual pixel rate also depends on quite a few other factors, most notably the memory bandwidth of the card - the lower the bandwidth is, the lower the potential to reach the maximum fill rate.
