VS

GeForce GTX 560 Ti vs Geforce GTX 690

Intro

The GeForce GTX 560 Ti features core speeds of 822 MHz on the GPU, and 1002 MHz on the 1024 MB of GDDR5 RAM. It features 384 SPUs as well as 64 TAUs and 32 ROPs.

Compare that to the Geforce GTX 690, which makes use of a 28 nm design. nVidia has set the core speed at 915 MHz. The GDDR5 memory runs at a frequency of 1502 MHz on this model. It features 1536 SPUs along with 128 Texture Address Units and 32 ROPs.

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

In theory, the Geforce GTX 690 will be 200% faster than the GeForce GTX 560 Ti in general, due to its higher data rate. (explain)

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

Texel Rate

The Geforce GTX 690 is quite a bit (about 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 high levels of AA 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 maximum amount of information (measured in megabytes per second) that can be transferred past the external memory interface in a second. It is calculated by multiplying the interface width by the speed of its memory. In the case of DDR memory, it must be multiplied by 2 once again. If it uses DDR5, multiply by 4 instead. The better the card's memory bandwidth, the better the card will be in general. It especially helps with anti-aliasing, High Dynamic Range and higher screen resolutions.

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

Pixel Rate: Pixel rate is the maximum number of pixels the graphics card can possibly write to its local memory in one second - measured in millions of pixels per second. The number is calculated by multiplying the number of colour ROPs by the the core 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 many other factors, most notably the memory bandwidth - the lower the memory bandwidth is, the lower the potential to get to the maximum fill rate.
