GeForce GTX 590 vs GeForce GTX 780 Ti

Intro

The GeForce GTX 590 uses a 40 nm design. nVidia has clocked the core frequency at 607 MHz. The GDDR5 RAM works at a frequency of 855 MHz on this specific model. It features 512 SPUs along with 64 Texture Address Units and 48 Rasterization Operator Units.

Compare all that to the GeForce GTX 780 Ti, which comes with a GPU core clock speed of 875 MHz, and 3072 MB of GDDR5 RAM set to run at 1750 MHz through a 384-bit bus. It also features 2880 Stream Processors, 240 Texture Address Units, and 48 Raster Operation Units.

Pixel Rate

If running with lots of anti-aliasing is important to you, then the GeForce GTX 590 is a better choice, and very much so. (explain)

GeForce GTX 590 58272 Mpixels/sec
GeForce GTX 780 Ti 42000 Mpixels/sec
Difference: 16272 (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 data (in units of MB per second) that can be transferred across the external memory interface in a second. The number is worked out by multiplying the card's interface width by its memory clock speed. If it uses DDR RAM, the result should be multiplied by 2 once again. If DDR5, multiply by ANOTHER 2x. The better the memory bandwidth, the faster 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 are applied in one second. This number is calculated by multiplying the total amount of texture units by the core speed of the chip. The higher this number, the better the video card will be at texture filtering (anisotropic filtering - AF). It is measured in millions of texels processed per second.

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