VS

GeForce GTX 560 Ti vs Geforce GTX 690

Intro

The GeForce GTX 560 Ti comes with a GPU core speed of 822 MHz, and the 1024 MB of GDDR5 RAM runs at 1002 MHz through a 256-bit bus. It also is made up of 384 SPUs, 64 Texture Address Units, and 32 Raster Operation Units.

Compare those specifications to the Geforce GTX 690, which comes with a clock frequency of 915 MHz and a GDDR5 memory frequency of 1502 MHz. It also uses a 256-bit bus, and makes use of a 28 nm design. It is comprised of 1536 SPUs, 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, because of its greater 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 will be quite a bit (approximately 345%) faster with regards to 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

The Geforce GTX 690 should be much (about 123%) more effective at full screen anti-aliasing than the GeForce GTX 560 Ti, and should be able to handle higher resolutions without slowing down too much. (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 (in units of MB per second) that can be moved over the external memory interface in one second. It's worked out by multiplying the card's interface width by the speed of its memory. In the case of DDR type memory, it must be multiplied by 2 once again. If DDR5, multiply by 4 instead. The better the memory bandwidth, the better the card will be in general. It especially helps with AA, High Dynamic Range and high resolutions.

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

Pixel Rate: Pixel rate is the maximum number of pixels the video card could possibly record to its local memory per second - measured in millions of pixels per second. The figure is worked out by multiplying the number of Raster Operations Pipelines by the the core speed of the card. ROPs (Raster Operations Pipelines - sometimes also referred to as Render Output Units) are responsible for filling the screen with pixels (the image). The actual pixel rate is also dependant on many other factors, most notably the memory bandwidth of the card - the lower the bandwidth is, the lower the ability to get to the maximum fill rate.
