GeForce GTX 580 vs Geforce GTX 680

Intro

The GeForce GTX 580 comes with core speeds of 772 MHz on the GPU, and 1002 MHz on the 1536 MB of GDDR5 memory. It features 512 SPUs along with 64 TAUs and 48 ROPs.

Compare those specs to the Geforce GTX 680, which has GPU core speed of 1006 MHz, and 2048 MB of GDDR5 RAM running at 1502 MHz through a 256-bit bus. It also is comprised of 1536 Stream Processors, 128 Texture Address Units, and 32 Raster Operation Units.

Power Usage and Theoretical Benchmarks

Power Consumption (Max TDP)

Geforce GTX 680 195 Watts
GeForce GTX 580 244 Watts
Difference: 49 Watts (25%)

Memory Bandwidth

The GeForce GTX 580 should in theory perform just a bit faster than the Geforce GTX 680 in general. (explain)

GeForce GTX 580 192384 MB/sec
Geforce GTX 680 192256 MB/sec
Difference: 128 (0%)

Texel Rate

The Geforce GTX 680 should be much (about 161%) faster with regards to AF than the GeForce GTX 580. (explain)

Geforce GTX 680 128768 Mtexels/sec
GeForce GTX 580 49408 Mtexels/sec
Difference: 79360 (161%)

Pixel Rate

If running with a high screen resolution is important to you, then the GeForce GTX 580 is a better choice, but it probably won't make a huge difference. (explain)

GeForce GTX 580 37056 Mpixels/sec
Geforce GTX 680 32192 Mpixels/sec
Difference: 4864 (15%)

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: Bandwidth is the max amount of information (measured in megabytes per second) that can be moved across the external memory interface in one second. It is calculated by multiplying the card's bus width by the speed of its memory. If the card has DDR type memory, it must be multiplied by 2 once again. If it uses DDR5, multiply by ANOTHER 2x. The better the bandwidth is, the better the card will be in general. It especially helps with AA, High Dynamic Range and higher screen resolutions.

Texel Rate: Texel rate is the maximum amount of texture map elements (texels) that are applied per second. This figure is calculated by multiplying the total number of texture units by the core speed of the chip. The better the texel rate, the better the card will be at texture filtering (anisotropic filtering - AF). It is measured in millions of texels applied in a second.

Pixel Rate: Pixel rate is the most pixels the graphics card could possibly write to its local memory in one second - measured in millions of pixels per second. The figure is worked out by multiplying the amount of ROPs by the the card's clock speed. ROPs (Raster Operations Pipelines - aka Render Output Units) are responsible for outputting the pixels (image) to the screen. The actual pixel output rate also depends on quite a few other factors, especially the memory bandwidth of the card - the lower the memory bandwidth is, the lower the ability to reach the max fill rate.

The leaked specs said that its powerful as 3 gtx 580s.Now we know thats just a stupid rumour.

well texel rate is

So this whole article is BS, performance is not based on theoretical information.
Waste of time.....

Gtx 580 is better!!
iHAR says:
580 better ?! Tt %61 at AF textures filtering. Only if you use high resolution without tex filters.
Ll 680 better for games regular pc
