GeForce GTX 580 vs Geforce GTX 680

Intro

The GeForce GTX 580 has a core clock speed of 772 MHz and a GDDR5 memory frequency of 1002 MHz. It also features a 384-bit bus, and uses a 40 nm design. It is comprised of 512 SPUs, 64 Texture Address Units, and 48 Raster Operation Units.

Compare all of that to the Geforce GTX 680, which makes use of a 28 nm design. nVidia has clocked the core frequency at 1006 MHz. The GDDR5 memory runs at a frequency of 1502 MHz on this particular model. It features 1536 SPUs along with 128 Texture Address Units and 32 Rasterization Operator 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

Theoretically speaking, the GeForce GTX 580 should be a small bit faster than the Geforce GTX 680 overall. (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 (approximately 161%) better at texture filtering than the GeForce GTX 580. (explain)

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

Pixel Rate

The GeForce GTX 580 should be a bit (more or less 15%) more effective at FSAA than the Geforce GTX 680, and capable of handling higher screen resolutions without losing too much performance. (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 maximum amount of data (in units of megabytes per second) that can be moved across the external memory interface within a second. The number is calculated by multiplying the card's bus width by the speed of its memory. In the case of DDR type RAM, the result should be multiplied by 2 once again. If DDR5, multiply by 4 instead. 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 texture map elements (texels) that can be applied per second. This number is calculated by multiplying the total amount of texture units of the card by the core clock speed of the chip. The better the texel rate, the better the graphics card will be at handling 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 per second - measured in millions of pixels per second. The figure is worked out by multiplying the number of Raster Operations Pipelines by the clock speed of the card. ROPs (Raster Operations Pipelines - also called Render Output Units) are responsible for filling the screen with pixels (the image). The actual pixel rate is also dependant on quite a few other factors, especially the memory bandwidth - the lower the memory bandwidth is, the lower the potential to get to the maximum 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
