GeForce GTX 460 2GB vs GeForce GTX 750

Intro

Compare those specifications to the GeForce GTX 750, which has core speeds of 1020 MHz on the GPU, and 1250 MHz on the 1024 MB of GDDR5 RAM. It features 512 SPUs as well as 32 Texture Address Units and 16 Rasterization Operator Units.

GeForce GTX 750		80000 MB/sec
	Difference: 35200 (44%)

Texel Rate

The GeForce GTX 460 2GB will be a small bit (approximately 16%) faster with regards to texture filtering than the GeForce GTX 750. (explain)

GeForce GTX 460 2GB		37800 Mtexels/sec
GeForce GTX 750		32640 Mtexels/sec
	Difference: 5160 (16%)

Pixel Rate

If using a high resolution is important to you, then the GeForce GTX 460 2GB is a better choice, by far. (explain)

GeForce GTX 460 2GB		21600 Mpixels/sec
GeForce GTX 750		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 maximum amount of information (in units of MB per second) that can be moved across the external memory interface in one second. The number is worked out by multiplying the card's bus width by its memory clock speed. If the card has DDR type memory, it should be multiplied by 2 once again. If it uses 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 higher screen resolutions.

Texel Rate: Texel rate is the maximum amount of texture map elements (texels) that can be applied per second. This number is calculated by multiplying the total amount of texture units of the card by the core speed of the chip. The higher this number, the better the graphics card will be at handling texture filtering (anisotropic filtering - AF). It is measured in millions of texels applied per second.

Pixel Rate: Pixel rate is the most pixels the video card could possibly record to the local memory in one 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 - also sometimes called Render Output Units) are responsible for outputting the pixels (image) to the screen. The actual pixel output rate also depends on lots of other factors, especially the memory bandwidth - the lower the bandwidth is, the lower the potential to reach the maximum fill rate.
