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 speed at 822 MHz. The GDDR5 memory is set to run at a speed of 1002 MHz on this particular card. It features 384 SPUs along with 64 Texture Address Units and 32 ROPs.

Compare those specs to the Geforce GTX 690, which has core clock speeds of 915 MHz on the GPU, and 1502 MHz on the 2048 MB of GDDR5 RAM. It features 1536 SPUs along with 128 TAUs and 32 Rasterization Operator Units.

Difference: 181632 (345%)

Pixel Rate

The Geforce GTX 690 should be much (approximately 123%) faster with regards to FSAA than the GeForce GTX 560 Ti, and also should be able to handle higher resolutions without losing too much performance. (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 maximum amount of information (measured in MB per second) that can be moved across the external memory interface in one second. It's worked out by multiplying the card's interface width by its memory clock speed. If the card has DDR type memory, it must be multiplied by 2 once again. If it uses DDR5, multiply by 4 instead. The better the bandwidth is, 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 number of texture map elements (texels) that are applied per second. This figure is calculated by multiplying the total amount of texture units by the core speed of the chip. The higher the texel rate, the better the graphics card will be at texture filtering (anisotropic filtering - AF). It is measured in millions of texels applied per second.

Pixel Rate: Pixel rate is the maximum number of pixels that the graphics chip could possibly write to the local memory in a second - measured in millions of pixels per second. Pixel rate is worked out by multiplying the amount of ROPs by the clock speed of the card. ROPs (Raster Operations Pipelines - also sometimes called Render Output Units) are responsible for drawing the pixels (image) on the screen. The actual pixel output rate is also dependant on lots of other factors, most notably the memory bandwidth of the card - the lower the memory bandwidth is, the lower the ability to get to the maximum fill rate.
