GeForce GTX 460 2GB vs GeForce GTX 750 Ti

Intro

Compare that to the GeForce GTX 750 Ti, which has a core clock frequency of 1020 MHz and a GDDR5 memory speed of 1350 MHz. It also makes use of a 128-bit memory bus, and uses a 28 nm design. It features 640 SPUs, 40 Texture Address Units, and 16 ROPs.

Power Usage and Theoretical Benchmarks

Power Consumption (Max TDP)

GeForce GTX 750 Ti		60 Watts
GeForce GTX 460 2GB		160 Watts
	Difference: 100 Watts (167%)

Memory Bandwidth

In theory, the GeForce GTX 460 2GB should be 33% faster than the GeForce GTX 750 Ti overall, because of its higher data rate. (explain)

GeForce GTX 460 2GB		115200 MB/sec
GeForce GTX 750 Ti		86400 MB/sec
	Difference: 28800 (33%)

Texel Rate

The GeForce GTX 750 Ti should be a little bit (more or less 8%) faster with regards to texture filtering than the GeForce GTX 460 2GB. (explain)

GeForce GTX 750 Ti		40800 Mtexels/sec
GeForce GTX 460 2GB		37800 Mtexels/sec
	Difference: 3000 (8%)

Pixel Rate

If using high levels of AA is important to you, then the GeForce GTX 460 2GB is superior to the GeForce GTX 750 Ti, and very much so. (explain)

GeForce GTX 460 2GB		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 max amount of data (counted in MB per second) that can be transferred across the external memory interface in one second. It is calculated by multiplying the card's interface width by the speed of its memory. In the case of DDR memory, it must 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 AA, High Dynamic Range and higher screen resolutions.

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

Pixel Rate: Pixel rate is the maximum number of pixels the graphics card could possibly record to the local memory per second - measured in millions of pixels per second. The figure is worked out by multiplying the number of Raster Operations Pipelines by the the core speed of the card. ROPs (Raster Operations Pipelines - aka Render Output Units) are responsible for drawing the pixels (image) on the screen. The actual pixel output rate also depends on lots of other factors, especially the memory bandwidth of the card - the lower the memory bandwidth is, the lower the potential to get to the max fill rate.
