Compare any two graphics cards:
GeForce GT 320 vs Radeon HD 6750 1GB
IntroThe GeForce GT 320 uses a 40 nm design. nVidia has clocked the core speed at 540 MHz. The GDDR3 RAM runs at a speed of 790 MHz on this specific model. It features 72 SPUs along with 24 Texture Address Units and 8 Rasterization Operator Units.Compare that to the Radeon HD 6750 1GB, which uses a 40 nm design. AMD has clocked the core frequency at 725 MHz. The GDDR5 memory runs at a frequency of 1000 MHz on this specific model. It features 720 SPUs along with 36 Texture Address Units and 16 ROPs.

Power Usage and Theoretical BenchmarksPower Consumption (Max TDP)
Memory BandwidthAs far as performance goes, the Radeon HD 6750 1GB should theoretically be much superior to the GeForce GT 320 in general. (explain)
Texel RateThe Radeon HD 6750 1GB should be quite a bit (more or less 101%) faster with regards to AF than the GeForce GT 320. (explain)
Pixel RateIf using high levels of AA is important to you, then the Radeon HD 6750 1GB is a better choice, by far. (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: Memory bandwidth is the maximum amount of data (in units of MB per second) that can be transferred across the external memory interface within a second. It's calculated by multiplying the interface width by its memory clock speed. In the case of DDR type memory, it must 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, 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 is worked out by multiplying the total texture units of the card by the core speed of the chip. The higher the texel rate, the better the graphics 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 amount of pixels the graphics card could possibly record to the local memory in one second - measured in millions of pixels per second. The number is calculated by multiplying the number of Raster Operations Pipelines by the clock speed of the card. ROPs (Raster Operations Pipelines - aka Render Output Units) are responsible for filling the screen with pixels (the image). The actual pixel fill rate also depends on many other factors, most notably the memory bandwidth of the card - the lower the memory bandwidth is, the lower the potential to get to the maximum fill rate.
