VS

GeForce GTX 560 Ti vs Geforce GTX 690

Intro

The GeForce GTX 560 Ti has a GPU core clock speed of 822 MHz, and the 1024 MB of GDDR5 RAM runs at 1002 MHz through a 256-bit bus. It also is comprised of 384 SPUs, 64 Texture Address Units, and 32 ROPs.

Compare those specifications to the Geforce GTX 690, which comes with a core clock speed of 915 MHz and a GDDR5 memory frequency of 1502 MHz. It also uses a 256-bit memory bus, and uses a 28 nm design. It is comprised of 1536 SPUs, 128 TAUs, and 32 ROPs.

Texel Rate

The Geforce GTX 690 should be much (approximately 345%) better at anisotropic 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 the winner, by a large margin. (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: Bandwidth is the max amount of data (counted in MB per second) that can be transported past the external memory interface within a second. It's calculated by multiplying the card's bus width by the speed of its memory. If the card has DDR memory, it should be multiplied by 2 once again. If DDR5, multiply by ANOTHER 2x. The higher the memory bandwidth, the faster the card will be in general. It especially helps with AA, HDR and higher screen resolutions.

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

Pixel Rate: Pixel rate is the most pixels that the graphics card can 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 ROPs by the clock speed of the card. ROPs (Raster Operations Pipelines - also called Render Output Units) are responsible for outputting the pixels (image) to the screen. The actual pixel fill rate is also dependant on lots of other factors, most notably the memory bandwidth - the lower the memory bandwidth is, the lower the potential to get to the maximum fill rate.
