Compare any two graphics cards:
GeForce 9400 GT 256MB vs Radeon HD 6950
IntroThe GeForce 9400 GT 256MB makes use of a 65 nm design. nVidia has clocked the core frequency at 550 MHz. The GDDR2 memory runs at a speed of 400 MHz on this particular model. It features 16 SPUs along with 8 TAUs and 4 Rasterization Operator Units.Compare that to the Radeon HD 6950, which comes with GPU core speed of 800 MHz, and 1024 MB of GDDR5 memory running at 1250 MHz through a 256-bit bus. It also features 1408 Stream Processors, 88 TAUs, and 32 Raster Operation Units.

Power Usage and Theoretical BenchmarksPower Consumption (Max TDP)
Memory BandwidthTheoretically speaking, the Radeon HD 6950 is 1150% quicker than the GeForce 9400 GT 256MB overall, due to its greater bandwidth. (explain)
Texel RateThe Radeon HD 6950 is much (more or less 1500%) more effective at texture filtering than the GeForce 9400 GT 256MB. (explain)
Pixel RateIf using high levels of AA is important to you, then the Radeon HD 6950 is superior to the GeForce 9400 GT 256MB, 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: Memory bandwidth is the largest amount of data (in units of MB per second) that can be moved across the external memory interface within a second. It's calculated by multiplying the card's bus width by its memory clock speed. If it uses DDR RAM, it must be multiplied by 2 once again. If DDR5, multiply by ANOTHER 2x. The better the memory bandwidth, the faster the card will be in general. It especially helps with anti-aliasing, High Dynamic Range 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 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 most pixels the video card could possibly write to its local memory in one second - measured in millions of pixels per second. The figure is worked out by multiplying the number of ROPs by the the core clock speed. ROPs (Raster Operations Pipelines - sometimes also referred to as Render Output Units) are responsible for drawing the pixels (image) on the screen. The actual pixel rate is also dependant on many other factors, most notably the memory bandwidth of the card - the lower the bandwidth is, the lower the ability to get to the max fill rate.
