GeForce GTX 590 vs Geforce GTX 770

Intro

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

Compare those specifications to the Geforce GTX 770, which comes with GPU core speed of 1046 MHz, and 2048 MB of GDDR5 RAM set to run at 1753 MHz through a 256-bit bus. It also features 1536 Stream Processors, 128 Texture Address Units, and 32 ROPs.

Texel Rate

The Geforce GTX 770 is much (more or less 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

The GeForce GTX 590 is a lot (about 74%) faster with regards to full screen anti-aliasing than the Geforce GTX 770, and will be able to handle higher screen resolutions more effectively. (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.

Memory Bandwidth: Memory bandwidth is the max amount of data (in units of MB per second) that can be transported over the external memory interface in one second. The number is calculated by multiplying the card's interface width by its memory speed. If the card has DDR memory, 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, HDR and high resolutions.

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

Pixel Rate: Pixel rate is the most pixels the graphics card could possibly record to the local memory in one second - measured in millions of pixels per second. Pixel rate is calculated by multiplying the number of colour ROPs by the the core clock speed. ROPs (Raster Operations Pipelines - sometimes also referred to as Render Output Units) are responsible for outputting the pixels (image) to the screen. The actual pixel rate also depends on lots of other factors, especially the memory bandwidth - the lower the memory bandwidth is, the lower the ability to get to the maximum fill rate.
