Compare any two graphics cards:
GeForce 8800 GTS (G80) 640MB vs Radeon HD 6450 (OEM) 1GB
IntroThe GeForce 8800 GTS (G80) 640MB makes use of a 90 nm design. nVidia has set the core frequency at 513 MHz. The GDDR3 RAM runs at a frequency of 792 MHz on this specific card. It features 96 SPUs along with 48 Texture Address Units and 20 ROPs.Compare those specifications to the Radeon HD 6450 (OEM) 1GB, which makes use of a 40 nm design. AMD has clocked the core frequency at 750 MHz. The GDDR5 memory is set to run at a speed of 900 MHz on this card. It features 160 SPUs as well as 8 Texture Address Units and 4 Rasterization Operator Units.

Power Usage and Theoretical BenchmarksPower Consumption (Max TDP)
Memory BandwidthAs far as performance goes, the GeForce 8800 GTS (G80) 640MB should in theory be much superior to the Radeon HD 6450 (OEM) 1GB in general. (explain)
Texel RateThe GeForce 8800 GTS (G80) 640MB is quite a bit (approximately 310%) more effective at AF than the Radeon HD 6450 (OEM) 1GB. (explain)
Pixel RateThe GeForce 8800 GTS (G80) 640MB will be much (about 242%) faster with regards to FSAA than the Radeon HD 6450 (OEM) 1GB, and able to handle higher screen resolutions without losing too much performance. (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 (measured in MB per second) that can be transported past the external memory interface in a second. It's worked out by multiplying the interface width by the speed of its memory. If the card has DDR type RAM, it must be multiplied by 2 once again. If DDR5, multiply by 4 instead. The better the card's memory bandwidth, the faster the card will be in general. It especially helps with AA, HDR 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 number of texture units by the core clock speed of the chip. The higher the texel rate, the better the card will be at handling texture filtering (anisotropic filtering - AF). It is measured in millions of texels applied per second. Pixel Rate: Pixel rate is the maximum amount of pixels that the graphics card can possibly record to its local memory per second - measured in millions of pixels per second. Pixel rate is calculated by multiplying the number of Render Output Units by the clock speed of the card. ROPs (Raster Operations Pipelines - aka Render Output Units) are responsible for drawing the pixels (image) on the screen. The actual pixel rate is also dependant on quite a few other factors, most notably the memory bandwidth of the card - the lower the bandwidth is, the lower the ability to get to the maximum fill rate.
