GeForce GTX 580 vs Geforce GTX 670

Intro

The GeForce GTX 580 has a GPU core speed of 772 MHz, and the 1536 MB of GDDR5 memory is set to run at 1002 MHz through a 384-bit bus. It also is comprised of 512 SPUs, 64 Texture Address Units, and 48 Raster Operation Units.

Compare those specifications to the Geforce GTX 670, which makes use of a 28 nm design. nVidia has clocked the core speed at 915 MHz. The GDDR5 memory runs at a frequency of 1500 MHz on this particular model. It features 1344 SPUs along with 112 TAUs and 32 ROPs.

Power Consumption (Max TDP)

Geforce GTX 670 170 Watts
GeForce GTX 580 244 Watts
Difference: 74 Watts (44%)

Memory Bandwidth

In theory, the GeForce GTX 580 should be 0% faster than the Geforce GTX 670 in general, due to its higher data rate. (explain)

GeForce GTX 580 192384 MB/sec
Geforce GTX 670 192000 MB/sec
Difference: 384 (0%)

Texel Rate

The Geforce GTX 670 will be much (approximately 107%) faster with regards to texture filtering than the GeForce GTX 580. (explain)

Geforce GTX 670 102480 Mtexels/sec
GeForce GTX 580 49408 Mtexels/sec
Difference: 53072 (107%)

Pixel Rate

If using a high resolution is important to you, then the GeForce GTX 580 is superior to the Geforce GTX 670, and very much so. (explain)

GeForce GTX 580 37056 Mpixels/sec
Geforce GTX 670 29280 Mpixels/sec
Difference: 7776 (27%)

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 data (counted in megabytes per second) that can be transported across the external memory interface in a second. It is calculated by multiplying the card's interface width by its memory clock speed. In the case of DDR memory, it must be multiplied by 2 once again. If it uses DDR5, multiply by ANOTHER 2x. The better the memory bandwidth, the better the card will be in general. It especially helps with AA, HDR and high resolutions.

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

Pixel Rate: Pixel rate is the most pixels the graphics 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 colour ROPs by the the core clock speed. ROPs (Raster Operations Pipelines - aka Render Output Units) are responsible for outputting the pixels (image) to the screen. The actual pixel rate also depends on many 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.
