Compare any two graphics cards:
GeForce GTX Titan vs Geforce GTX 690
IntroThe GeForce GTX Titan comes with core speeds of 837 MHz on the GPU, and 1502 MHz on the 6144 MB of GDDR5 memory. It features 2688 SPUs as well as 224 TAUs and 48 Rasterization Operator Units.
Compare those specs to the Geforce GTX 690, which makes use of a 28 nm design. nVidia has clocked the core speed at 915 MHz. The GDDR5 RAM is set to run at a speed of 1502 MHz on this card. It features 1536 SPUs along with 128 TAUs and 32 ROPs.

Power Usage and Theoretical Benchmarks
Power Consumption (Max TDP)
The Geforce GTX 690, in theory, should perform much faster than the GeForce GTX Titan in general. (explain)
Texel RateThe Geforce GTX 690 should be quite a bit (more or less 25%) faster with regards to AF than the GeForce GTX Titan. (explain)
Pixel RateThe Geforce GTX 690 should be much (approximately 46%) faster with regards to anti-aliasing than the GeForce GTX Titan, and able to handle higher screen resolutions better. (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: Memory bandwidth is the largest amount of data (measured in megabytes per second) that can be transferred across the external memory interface in one second. The number is worked out by multiplying the bus width by the speed of its memory. In the case of DDR RAM, it should be multiplied by 2 again. If DDR5, multiply by ANOTHER 2x. The better the memory bandwidth, the better the card will be in general. It especially helps with anti-aliasing, High Dynamic Range and high 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 better this number, the better the video 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 amount of pixels that the graphics card can possibly write to the local memory in one second - measured in millions of pixels per second. Pixel rate is calculated by multiplying the amount 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 filling the screen with pixels (the image). The actual pixel output rate also depends on quite a few other factors, most notably the memory bandwidth - the lower the memory bandwidth is, the lower the ability to get to the maximum fill rate.
