GeForce GTX 580 vs GeForce GTX 580 3GB
Intro
The GeForce GTX 580 has a core clock frequency of 772 MHz and a GDDR5 memory frequency of 1002 MHz. It also uses a 384-bit memory bus, and uses a 40 nm design. It features 512 SPUs, 64 TAUs, and 48 ROPs.Compare all of that to the GeForce GTX 580 3GB, which features a core clock speed of 772 MHz and a GDDR5 memory frequency of 1002 MHz. It also uses a 384-bit bus, and uses a 40 nm design. It features 512 SPUs, 64 TAUs, and 48 ROPs.
Power Usage and Theoretical Benchmarks
Both cards have the same power consumption.Memory Bandwidth
Both cards have the exact same memory bandwidth, so in theory they should have the same performance. (explain)
Texel Rate
Both cards have exactly the same texel fill rate, so theoretically they should perform equally good at at AF. (explain)Pixel Rate
Both cards have exactly the same pixel fill rate, so in theory they should be equally good at at AA, and be able to handle the same screen resolutions. (explain)
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.

Memory Bandwidth: Memory bandwidth is the largest amount of information (counted in MB per second) that can be transported across the external memory interface within a second. It's calculated by multiplying the bus width by the speed of its memory. If the card has DDR type RAM, it should be multiplied by 2 again. If DDR5, multiply by ANOTHER 2x. The higher the card's memory bandwidth, the faster the card will be in general. It especially helps with anti-aliasing, High Dynamic Range and high resolutions.
Texel Rate: Texel rate is the maximum texture map elements (texels) that are processed in one second. This number is calculated 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 texture filtering (anisotropic filtering - AF). It is measured in millions of texels per second.
Pixel Rate: Pixel rate is the maximum amount of pixels the video card could possibly write to its local memory in a second - measured in millions of pixels per second. Pixel rate is worked out by multiplying the amount of Raster Operations Pipelines by the the card's clock speed. ROPs (Raster Operations Pipelines - also sometimes called Render Output Units) are responsible for filling the screen with pixels (the image). The actual pixel output rate also depends on many other factors, especially the memory bandwidth of the card - the lower the memory bandwidth is, the lower the potential to get to the max fill rate.

2 Responses to “GeForce GTX 580 vs GeForce GTX 580 3GB”So, uh, what's the difference? >_>
I couldn't get the difference because the site considers them both to have identical results. In real world terms, I doubt the difference is substantial unless you're running a multi-monitor setup anyway.
