Compare any two graphics cards:
GeForce GT 320 vs Geforce GTX 670
IntroThe GeForce GT 320 makes use of a 40 nm design. nVidia has set the core speed at 540 MHz. The GDDR3 memory works at a frequency of 790 MHz on this particular card. It features 72 SPUs along with 24 Texture Address Units and 8 ROPs.Compare those specs to the Geforce GTX 670, which comes with a clock frequency of 915 MHz and a GDDR5 memory frequency of 1500 MHz. It also makes use of a 256-bit bus, and uses a 28 nm design. It features 1344 SPUs, 112 TAUs, and 32 ROPs.

Power Usage and Theoretical BenchmarksPower Consumption (Max TDP)
Memory BandwidthIn theory, the Geforce GTX 670 should perform a lot faster than the GeForce GT 320 in general. (explain)
Texel RateThe Geforce GTX 670 should be a lot (approximately 691%) more effective at AF than the GeForce GT 320. (explain)
Pixel RateIf using lots of anti-aliasing is important to you, then the Geforce GTX 670 is a better choice, by a large margin. (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 Comparison

Display Specifications
Memory Bandwidth: Bandwidth is the largest amount of data (counted in megabytes per second) that can be transported across the external memory interface in a second. It is worked out by multiplying the bus width by the speed of its memory. If it uses DDR memory, it should be multiplied by 2 again. If it uses DDR5, multiply by 4 instead. The higher the memory bandwidth, the faster 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 number is calculated by multiplying the total amount of texture units of the card by the core 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 per second. Pixel Rate: Pixel rate is the maximum amount of pixels the graphics card could possibly record to its local memory in one second - measured in millions of pixels per second. The number is calculated by multiplying the number of ROPs by the clock speed of the card. ROPs (Raster Operations Pipelines - sometimes also referred to as Render Output Units) are responsible for outputting the pixels (image) to the screen. The actual pixel fill rate is also dependant on many other factors, especially the memory bandwidth of the card - the lower the memory bandwidth is, the lower the ability to reach the maximum fill rate.
