GeForce GTX 590 vs Geforce GTX 770

Intro

Compare that to the Geforce GTX 770, which uses a 28 nm design. nVidia has set the core speed at 1046 MHz. The GDDR5 RAM is set to run at a speed of 1753 MHz on this specific card. It features 1536 SPUs along with 128 Texture Address Units and 32 ROPs.

Geforce GTX 770		224384 MB/sec
	Difference: 103936 (46%)

Texel Rate

The Geforce GTX 770 will be quite a bit (about 72%) more effective at AF than the GeForce GTX 590. (explain)

Geforce GTX 770		133888 Mtexels/sec
GeForce GTX 590		77696 Mtexels/sec
	Difference: 56192 (72%)

Pixel Rate

If using lots of anti-aliasing is important to you, then the GeForce GTX 590 is the winner, and very much so. (explain)

GeForce GTX 590		58272 Mpixels/sec
Geforce GTX 770		33472 Mpixels/sec
	Difference: 24800 (74%)

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.

Specifications

Memory Bandwidth: Bandwidth is the maximum amount of data (counted in megabytes per second) that can be moved over the external memory interface in a second. The number is calculated by multiplying the interface width by its memory speed. In the case of DDR type RAM, it must be multiplied by 2 again. If DDR5, multiply by 4 instead. The better the bandwidth is, the faster the card will be in general. It especially helps with anti-aliasing, HDR and high resolutions.

Texel Rate: Texel rate is the maximum texture map elements (texels) that are applied per second. This number 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 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 most pixels that the graphics card could possibly write to its local memory per second - measured in millions of pixels per second. The figure is calculated by multiplying the number of ROPs by the clock speed of the card. ROPs (Raster Operations Pipelines - also called Render Output Units) are responsible for drawing the pixels (image) on the screen. The actual pixel output rate is also dependant on quite a few other factors, especially the memory bandwidth of the card - the lower the bandwidth is, the lower the potential to reach the maximum fill rate.
