VS

GeForce GTX 570 vs Geforce GTX 670

Intro

The GeForce GTX 570 uses a 40 nm design. nVidia has clocked the core speed at 732 MHz. The GDDR5 RAM works at a speed of 950 MHz on this specific card. It features 480 SPUs as well as 60 Texture Address Units and 40 ROPs.

Compare all of that to the Geforce GTX 670, which features GPU core speed of 915 MHz, and 2048 MB of GDDR5 RAM running at 1500 MHz through a 256-bit bus. It also is comprised of 1344 SPUs, 112 TAUs, and 32 Raster Operation Units.

Power Usage and Theoretical Benchmarks

Power Consumption (Max TDP)

Geforce GTX 670 170 Watts
GeForce GTX 570 219 Watts
Difference: 49 Watts (29%)

Memory Bandwidth

Theoretically speaking, the Geforce GTX 670 should perform quite a bit faster than the GeForce GTX 570 overall. (explain)

Geforce GTX 670 192000 MB/sec
GeForce GTX 570 152000 MB/sec
Difference: 40000 (26%)

Texel Rate

The Geforce GTX 670 should be quite a bit (approximately 133%) faster with regards to anisotropic filtering 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 exactly the same pixel fill rate, so theoretically they should be equally good at at FSAA, and be able to handle the same 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: Bandwidth is the maximum amount of data (in units of MB per second) that can be transferred past the external memory interface within a second. The number is calculated by multiplying the card's interface width by the speed of its memory. In the case of DDR RAM, it should be multiplied by 2 once again. If it uses DDR5, multiply by 4 instead. The better the memory bandwidth, the better the card will be in general. It especially helps with anti-aliasing, HDR and high resolutions.

Texel Rate: Texel rate is the maximum amount of texture map elements (texels) that are processed per second. This is worked out by multiplying the total 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 in a second.

Pixel Rate: Pixel rate is the maximum number of pixels the graphics card can possibly record to the local memory in one second - measured in millions of pixels per second. Pixel rate is worked out by multiplying the amount of ROPs by the the core clock speed. 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 lots of other factors, most notably the memory bandwidth of the card - the lower the bandwidth is, the lower the potential to get to the maximum fill rate.
