Compare any two graphics cards:
GeForce GTX 580 vs Geforce GTX 670
IntroThe GeForce GTX 580 makes use of a 40 nm design. nVidia has set the core speed at 772 MHz. The GDDR5 RAM runs at a frequency of 1002 MHz on this specific model. It features 512 SPUs along with 64 TAUs and 48 Rasterization Operator Units.
Compare those specs to the Geforce GTX 670, which makes use of a 28 nm design. nVidia has clocked the core frequency at 915 MHz. The GDDR5 RAM runs at a speed of 1500 MHz on this specific card. It features 1344 SPUs along with 112 TAUs and 32 Rasterization Operator Units.

Power Usage and Theoretical Benchmarks
Power Consumption (Max TDP)
The GeForce GTX 580 should in theory be a little bit faster than the Geforce GTX 670 in general. (explain)
Texel RateThe Geforce GTX 670 is much (approximately 107%) better at AF than the GeForce GTX 580. (explain)
Pixel RateThe GeForce GTX 580 is much (more or less 27%) faster with regards to FSAA than the Geforce GTX 670, and will be capable of handling higher screen resolutions better. (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.
Price ComparisonPlease note that the price comparisons are based on search keywords, and might not be the exact same card listed on this page. We have no control over the accuracy of their search results.
Memory Bandwidth: Memory bandwidth is the maximum amount of data (counted in megabytes per second) that can be transferred past the external memory interface in a second. It's calculated by multiplying the card's interface width by the speed of its memory. In the case of DDR RAM, the result should be multiplied by 2 again. If it uses DDR5, multiply by ANOTHER 2x. The higher the bandwidth is, the better the card will be in general. It especially helps with anti-aliasing, High Dynamic Range and higher screen resolutions.
Texel Rate: Texel rate is the maximum texture map elements (texels) that are processed in one second. This is worked out by multiplying the total number of texture units of the card by the core clock speed of the chip. The higher this number, the better the video card will be at handling texture filtering (anisotropic filtering - AF). It is measured in millions of texels processed in one second.
Pixel Rate: Pixel rate is the maximum number of pixels the graphics card can possibly write to its local memory in a second - measured in millions of pixels per second. The figure is calculated by multiplying the amount of ROPs by the the card's clock speed. ROPs (Raster Operations Pipelines - also sometimes called Render Output Units) are responsible for drawing the pixels (image) on the screen. The actual pixel fill rate also depends on many other factors, especially the memory bandwidth of the card - the lower the memory bandwidth is, the lower the potential to reach the maximum fill rate.
