Compare any two graphics cards:
GeForce GTX Titan vs Geforce GTX 690
IntroThe GeForce GTX Titan comes with a GPU clock speed of 837 MHz, and the 6144 MB of GDDR5 memory is set to run at 1502 MHz through a 384-bit bus. It also features 2688 SPUs, 224 Texture Address Units, and 48 Raster Operation Units.
Compare all that to the Geforce GTX 690, which makes use of a 28 nm design. nVidia has set the core frequency at 915 MHz. The GDDR5 RAM works at a speed of 1502 MHz on this specific model. It features 1536 SPUs along with 128 Texture Address Units and 32 ROPs.

Power Usage and Theoretical Benchmarks
Power Consumption (Max TDP)
As far as performance goes, the Geforce GTX 690 should in theory be a lot superior to the GeForce GTX Titan overall. (explain)
Texel RateThe Geforce GTX 690 is quite a bit (approximately 25%) faster with regards to anisotropic filtering than the GeForce GTX Titan. (explain)
Pixel RateIf using a high resolution is important to you, then the Geforce GTX 690 is the winner, by far. (explain)
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.
Price ComparisonPlease note that the price comparisons are based on search keywords, and might not be the exact same card listed on this page. We have no control over the accuracy of their search results.
Memory Bandwidth: Bandwidth is the largest amount of information (in units of megabytes per second) that can be transferred over the external memory interface in one second. The number is calculated by multiplying the card's interface width by its memory speed. If the card has DDR RAM, it should be multiplied by 2 again. If DDR5, multiply by ANOTHER 2x. The better the card's memory bandwidth, the faster the card will be in general. It especially helps with AA, HDR and high resolutions.
Texel Rate: Texel rate is the maximum amount of texture map elements (texels) that are processed in one second. This figure is calculated by multiplying the total amount of texture units of the card by the core clock speed of the chip. The better 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 in one second.
Pixel Rate: Pixel rate is the maximum amount of pixels the graphics card could possibly write to the local memory in a second - measured in millions of pixels per second. The number is calculated by multiplying the amount of Render Output Units by the clock speed of the card. ROPs (Raster Operations Pipelines - also sometimes called Render Output Units) are responsible for filling the screen with pixels (the image). The actual pixel fill rate also depends on quite a few other factors, especially the memory bandwidth of the card - the lower the bandwidth is, the lower the potential to reach the max fill rate.
