GeForce GTX 560 Ti vs Geforce GTX 690

Intro

The GeForce GTX 560 Ti makes use of a 40 nm design. nVidia has set the core frequency at 822 MHz. The GDDR5 memory works at a frequency of 1002 MHz on this particular model. It features 384 SPUs as well as 64 TAUs and 32 ROPs.

Compare all of that to the Geforce GTX 690, which comes with GPU clock speed of 915 MHz, and 2048 MB of GDDR5 RAM running at 1502 MHz through a 256-bit bus. It also is comprised of 1536 SPUs, 128 TAUs, and 32 Raster Operation Units.

Power Usage and Theoretical Benchmarks

Power Consumption (Max TDP)

GeForce GTX 560 Ti 170 Watts
Geforce GTX 690 300 Watts
Difference: 130 Watts (76%)

Memory Bandwidth

The Geforce GTX 690, in theory, should be much faster than the GeForce GTX 560 Ti overall. (explain)

Geforce GTX 690 384512 MB/sec
GeForce GTX 560 Ti 128256 MB/sec
Difference: 256256 (200%)

Texel Rate

The Geforce GTX 690 should be a lot (more or less 345%) better at texture filtering than the GeForce GTX 560 Ti. (explain)

Geforce GTX 690 234240 Mtexels/sec
GeForce GTX 560 Ti 52608 Mtexels/sec
Difference: 181632 (345%)

Pixel Rate

If using a high resolution is important to you, then the Geforce GTX 690 is a better choice, by far. (explain)

Geforce GTX 690 58560 Mpixels/sec
GeForce GTX 560 Ti 26304 Mpixels/sec
Difference: 32256 (123%)

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.

Memory Bandwidth: Memory bandwidth is the largest amount of data (counted in megabytes per second) that can be transported past the external memory interface within a second. It is calculated by multiplying the interface width by the speed of its memory. In the case of DDR type memory, it should be multiplied by 2 once again. If it uses DDR5, multiply by 4 instead. The higher the card's 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 in one second. This number is calculated by multiplying the total texture units by the core clock speed of the chip. The better the texel rate, the better the video card will be at texture filtering (anisotropic filtering - AF). It is measured in millions of texels in a second.

Pixel Rate: Pixel rate is the maximum amount of pixels the graphics card could possibly record to its local memory in one second - measured in millions of pixels per second. The figure is worked out by multiplying the amount of colour ROPs by the clock 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 rate is also dependant on quite a few other factors, most notably the memory bandwidth - the lower the bandwidth is, the lower the potential to reach the maximum fill rate.
