GeForce GTX 780 Ti vs Geforce GTX 690

Intro

The GeForce GTX 780 Ti makes use of a 28 nm design. nVidia has set the core frequency at 875 MHz. The GDDR5 RAM works at a speed of 1750 MHz on this specific card. It features 2880 SPUs as well as 240 Texture Address Units and 48 Rasterization Operator Units.

Compare all of that to the Geforce GTX 690, which makes use of a 28 nm design. nVidia has clocked the core speed at 915 MHz. The GDDR5 memory works at a speed of 1502 MHz on this particular model. It features 1536 SPUs along with 128 TAUs and 32 Rasterization Operator Units.

Pixel Rate

The Geforce GTX 690 should be quite a bit (more or less 39%) more effective at FSAA than the GeForce GTX 780 Ti, and will be capable of handling higher screen resolutions while still performing well. (explain)

Geforce GTX 690 58560 Mpixels/sec
GeForce GTX 780 Ti 42000 Mpixels/sec
Difference: 16560 (39%)

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 is worked out by multiplying the interface width by its memory clock speed. If the card has DDR RAM, it should be multiplied by 2 once again. If it uses DDR5, multiply by ANOTHER 2x. The higher the card's memory bandwidth, the better the card will be in general. It especially helps with AA, HDR and high resolutions.

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

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

LOL everyone says GTX 780Ti is the best GPU on the planet well if the would make a dualcore GTX 690 or they would put GTX 690 cores in GTX 780Ti than that would be the best and it's not 'that' hard to do...

KRisz says:

And GTX 690 is cheaper a lot

Thom says:

Nvidia said that the GTX 780 TI is the fastes SINGLE gpu on the planet.And also the 690 is a DUAL gpu card.The 960 also costs 300-400 more...

Thom says:

Sorry in the last sentence i wrote 960 but i ment 690

Mehran says:

I wanna Purchase this card , but How much money i have to purchase this!

Robert James Rindik says:

People, you must understand that the GeForce GTX 780 Ti is a single GPU graphics card where the GeForce GTX 690 is dual GPU graphics card.
The GeForce GTX 790 will also be dual GPU graphics card, and it will outlast any graphic cards by a lot.

Bob Stones says:

How much is the 690.

pepe says:

Look on ebay, gtx 690 awesome, 2 kepler gpu's 😀
