GeForce GTX 570 vs Geforce GTX 670


Intro

The GeForce GTX 570 features a GPU core clock speed of 732 MHz, and the 1280 MB of GDDR5 memory runs at 950 MHz through a 320-bit bus. It also is comprised of 480 Stream Processors, 60 TAUs, and 40 Raster Operation Units.

Compare those specs to the Geforce GTX 670, which has core clock speeds of 915 MHz on the GPU, and 1500 MHz on the 2048 MB of GDDR5 RAM. It features 1344 SPUs along with 112 TAUs and 32 ROPs.

GeForce GTX 570 152000 MB/sec
Difference: 40000 (26%)

Texel Rate

The Geforce GTX 670 should be a lot (about 133%) more effective at AF than the GeForce GTX 570. (explain)

Geforce GTX 670 102480 Mtexels/sec
GeForce GTX 570 43920 Mtexels/sec
Difference: 58560 (133%)

Pixel Rate

Both cards have the exact same pixel fill rate, so theoretically they should be equally good at at anti-aliasing, 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 information (measured in megabytes per second) that can be transferred across the external memory interface within a second. It is calculated by multiplying the interface width by its memory speed. If it uses DDR type memory, it should be multiplied by 2 once again. If DDR5, multiply by 4 instead. The higher the memory bandwidth, the faster 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 number of texture map elements (texels) that are applied per second. This number is worked out by multiplying the total number of texture units by the core speed of the chip. The better the texel rate, the better the video 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 video card can possibly write to the local memory in a second - measured in millions of pixels per second. The number is calculated by multiplying the amount of Render Output Units by the clock speed of the card. ROPs (Raster Operations Pipelines - also sometimes called Render Output Units) are responsible for outputting the pixels (image) to the screen. The actual pixel rate is also dependant on quite a few other factors, especially the memory bandwidth of the card - the lower the memory bandwidth is, the lower the potential to reach the max fill rate.
