GeForce GTX 580 vs GeForce GTX 580 3GB

Intro

The GeForce GTX 580 features a GPU clock speed of 772 MHz, and the 1536 MB of GDDR5 RAM is set to run at 1002 MHz through a 384-bit bus. It also features 512 SPUs, 64 TAUs, and 48 ROPs.

Compare those specs to the GeForce GTX 580 3GB, which features GPU clock speed of 772 MHz, and 3072 MB of GDDR5 memory set to run at 1002 MHz through a 384-bit bus. It also is made up of 512 SPUs, 64 TAUs, and 48 ROPs.

Power Usage and Theoretical Benchmarks

Both cards have the same power consumption.

Memory Bandwidth

Both cards have exactly the same memory bandwidth, so theoretically they should perform exactly the same. (explain)

Texel Rate

Both cards have the exact same texel rate, so theoretically they should be equally good at at AF. (explain)

Pixel Rate

Both cards have exactly the same pixel fill rate, so theoretically they should perform equally good at at FSAA, 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 max amount of data (measured in megabytes per second) that can be transferred past the external memory interface in one second. It's calculated by multiplying the card's interface width by its memory clock speed. In the case of DDR memory, the result should be multiplied by 2 again. If it uses DDR5, multiply by ANOTHER 2x. The higher the card's memory bandwidth, the faster 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 are processed per second. This number is calculated by multiplying the total texture units by the core speed of the chip. The higher the texel rate, the better the 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 amount of pixels that the graphics chip could possibly write to its local memory per second - measured in millions of pixels per second. Pixel rate is calculated by multiplying the number of ROPs by the the core 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 rate is also dependant on many other factors, most notably the memory bandwidth - the lower the bandwidth is, the lower the ability to reach the maximum fill rate.

So, uh, what's the difference? >_>

Will says:

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.
