GeForce GTX 580 3GB vs Geforce GTX 690

Intro

The GeForce GTX 580 3GB uses a 40 nm design. nVidia has set the core frequency at 772 MHz. The GDDR5 memory is set to run at a frequency of 1002 MHz on this particular model. It features 512 SPUs along with 64 TAUs and 48 ROPs.

Compare all that to the Geforce GTX 690, which features a clock frequency of 915 MHz and a GDDR5 memory speed of 1502 MHz. It also makes use of a 256-bit memory bus, and makes use of a 28 nm design. It is made up of 1536 SPUs, 128 Texture Address Units, and 32 ROPs.

Power Usage and Theoretical Benchmarks

Power Consumption (Max TDP)

GeForce GTX 580 3GB 244 Watts
Geforce GTX 690 300 Watts
Difference: 56 Watts (23%)

Memory Bandwidth

Theoretically speaking, the Geforce GTX 690 will be 100% quicker than the GeForce GTX 580 3GB in general, because of its higher bandwidth. (explain)

Geforce GTX 690 384512 MB/sec
GeForce GTX 580 3GB 192384 MB/sec
Difference: 192128 (100%)

Texel Rate

The Geforce GTX 690 should be much (more or less 374%) better at anisotropic filtering than the GeForce GTX 580 3GB. (explain)

Geforce GTX 690 234240 Mtexels/sec
GeForce GTX 580 3GB 49408 Mtexels/sec
Difference: 184832 (374%)

Pixel Rate

The Geforce GTX 690 is a lot (approximately 58%) faster with regards to AA than the GeForce GTX 580 3GB, and also will be able to handle higher screen resolutions better. (explain)

Geforce GTX 690 58560 Mpixels/sec
GeForce GTX 580 3GB 37056 Mpixels/sec
Difference: 21504 (58%)

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 max amount of information (counted in megabytes per second) that can be transferred past the external memory interface in one second. It is worked out by multiplying the card's bus width by the speed of its memory. In the case of DDR type RAM, it must be multiplied by 2 once again. If DDR5, multiply by 4 instead. The higher the card's memory bandwidth, the better 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 can be processed in one second. This is worked out by multiplying the total number of texture units of the card by the core speed of the chip. The better this number, the better the video 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 that the graphics card can 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 ROPs by the clock speed of the card. 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 is also dependant on many other factors, especially the memory bandwidth - the lower the bandwidth is, the lower the potential to reach the max fill rate.
