VS

GeForce GTX 590 vs Geforce GTX 770

Intro

The GeForce GTX 590 makes use of a 40 nm design. nVidia has set the core speed at 607 MHz. The GDDR5 memory is set to run at a speed of 855 MHz on this particular card. It features 512 SPUs along with 64 Texture Address Units and 48 Rasterization Operator Units.

Compare those specifications to the Geforce GTX 770, which features a clock speed of 1046 MHz and a GDDR5 memory frequency of 1753 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.

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

Pixel Rate

If using a high screen resolution is important to you, then the GeForce GTX 590 is superior to the Geforce GTX 770, by a large margin. (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: Bandwidth is the maximum amount of information (measured in MB per second) that can be moved across the external memory interface within a second. It's worked out by multiplying the bus width by its memory clock speed. If it uses DDR type memory, it should be multiplied by 2 once again. If it uses DDR5, multiply by 4 instead. The higher 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 amount of texture map elements (texels) that can be applied in one second. This number is worked out by multiplying the total number of texture units by the core speed of the chip. The higher the texel rate, the better the graphics card will be at handling texture filtering (anisotropic filtering - AF). It is measured in millions of texels per second.

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