GeForce GTX 460 (OEM) vs Geforce GTX 690

Intro

Compare all of that to the Geforce GTX 690, which makes use of a 28 nm design. nVidia has set the core speed at 915 MHz. The GDDR5 RAM runs at a speed of 1502 MHz on this specific card. It features 1536 SPUs as well as 128 TAUs and 32 ROPs.

GeForce GTX 460 (OEM)		36400 Mtexels/sec
	Difference: 197840 (544%)

Pixel Rate

If using lots of anti-aliasing is important to you, then the Geforce GTX 690 is the winner, by a large margin. (explain)

Geforce GTX 690		58560 Mpixels/sec
GeForce GTX 460 (OEM)		20800 Mpixels/sec
	Difference: 37760 (182%)

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.

One or more cards in this comparison are multi-core. This means that their bandwidth, texel and pixel rates are theoretically doubled - this does not mean the card will actually perform twice as fast, but only that it should in theory be able to. Actual game benchmarks will give a more accurate idea of what it's capable of.

Specifications

Memory Bandwidth: Memory bandwidth is the largest amount of information (measured in MB per second) that can be transferred across the external memory interface in one second. It's worked out by multiplying the card's interface width by the speed of its memory. In the case of DDR type memory, it should be multiplied by 2 again. If it uses DDR5, multiply by 4 instead. The higher the bandwidth is, the better the card will be in general. It especially helps with anti-aliasing, HDR 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 amount of texture units by the core speed of the chip. The better this number, the better the graphics card will be at handling texture filtering (anisotropic filtering - AF). It is measured in millions of texels in one second.

Pixel Rate: Pixel rate is the maximum amount of pixels that the graphics card can possibly record to the local memory per second - measured in millions of pixels per second. The number is calculated by multiplying the amount of Raster Operations Pipelines by the the core clock speed. 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 lots of 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.
