Compare any two graphics cards:
GeForce 9500 GT 1GB GDDR3 vs Radeon HD 3690/3830
IntroThe GeForce 9500 GT 1GB GDDR3 makes use of a 55 nm design. nVidia has set the core frequency at 550 MHz. The GDDR3 RAM works at a frequency of 800 MHz on this particular card. It features 32 SPUs along with 16 Texture Address Units and 8 Rasterization Operator Units.Compare those specs to the Radeon HD 3690/3830, which makes use of a 55 nm design. AMD has set the core frequency at 668 MHz. The GDDR3 RAM works at a speed of 828 MHz on this model. It features 320(64x5) SPUs as well as 16 TAUs and 16 Rasterization Operator Units.

Power Usage and Theoretical BenchmarksPower Consumption (Max TDP)
Memory BandwidthPerformance-wise, the Radeon HD 3690/3830 should theoretically be a bit superior to the GeForce 9500 GT 1GB GDDR3 overall. (explain)
Texel RateThe Radeon HD 3690/3830 will be quite a bit (about 21%) more effective at AF than the GeForce 9500 GT 1GB GDDR3. (explain)
Pixel RateIf using high levels of AA is important to you, then the Radeon HD 3690/3830 is the winner, 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 information (measured in megabytes per second) that can be transported across the external memory interface in a second. The number is worked out by multiplying the card's interface width by its memory speed. If the card has DDR RAM, it should be multiplied by 2 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 high resolutions. Texel Rate: Texel rate is the maximum amount of texture map elements (texels) that are processed in one second. This is calculated by multiplying the total texture units by the core clock speed of the chip. The higher this number, the better the graphics card will be at handling texture filtering (anisotropic filtering - AF). It is measured in millions of texels applied in a second. Pixel Rate: Pixel rate is the maximum number of pixels that the graphics card can possibly record to the local memory in a second - measured in millions of pixels per second. The figure is worked out by multiplying the number of colour ROPs by the the core clock speed. ROPs (Raster Operations Pipelines - also sometimes called Render Output Units) are responsible for outputting the pixels (image) to the screen. The actual pixel fill rate is also dependant on lots of other factors, especially the memory bandwidth - the lower the memory bandwidth is, the lower the ability to reach the max fill rate.
