VS

GeForce GTX 590 vs Geforce GTX 770

Intro

The GeForce GTX 590 comes with a GPU core clock speed of 607 MHz, and the 1536 MB of GDDR5 RAM runs at 855 MHz through a 384-bit bus. It also is made up of 512 SPUs, 64 TAUs, and 48 ROPs.

Compare those specifications to the Geforce GTX 770, which features clock speeds of 1046 MHz on the GPU, and 1753 MHz on the 2048 MB of GDDR5 RAM. It features 1536 SPUs as well as 128 Texture Address Units and 32 Rasterization Operator Units.

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 texture filtering 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 should be much (more or less 74%) faster with regards to AA than the Geforce GTX 770, and also will be capable of handling higher screen resolutions without losing too much performance. (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 maximum amount of data (counted in megabytes per second) that can be moved across the external memory interface in one second. It's worked out by multiplying the interface width by its memory clock speed. If it uses DDR RAM, it must be multiplied by 2 again. If it uses DDR5, multiply by ANOTHER 2x. The better the card's 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 number of texture map elements (texels) that can be applied per second. This is worked out by multiplying the total amount of texture units of the card by the core speed of the chip. The higher this number, the better the graphics card will be at handling texture filtering (anisotropic filtering - AF). It is measured in millions of texels in one second.

Pixel Rate: Pixel rate is the most pixels that the graphics card can possibly record to its local memory in one second - measured in millions of pixels per second. The number is worked out by multiplying the number of colour 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 fill rate also depends on quite a few other factors, most notably the memory bandwidth of the card - the lower the memory bandwidth is, the lower the potential to reach the max fill rate.
