Compare any two graphics cards:
GeForce 9800 GTX vs Radeon HD 6450 (OEM)
IntroThe GeForce 9800 GTX has a GPU core speed of 675 MHz, and the 512 MB of GDDR3 RAM runs at 1100 MHz through a 256-bit bus. It also features 128 Stream Processors, 64 Texture Address Units, and 16 ROPs.Compare all of that to the Radeon HD 6450 (OEM), which uses a 40 nm design. AMD has set the core frequency at 625 MHz. The GDDR3 memory runs at a speed of 800 MHz on this specific 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 BandwidthIn theory, the GeForce 9800 GTX is 450% faster than the Radeon HD 6450 (OEM) in general, due to its higher data rate. (explain)
Texel RateThe GeForce 9800 GTX will be quite a bit (more or less 764%) better at texture filtering than the Radeon HD 6450 (OEM). (explain)
Pixel RateThe GeForce 9800 GTX is much (approximately 332%) more effective at AA than the Radeon HD 6450 (OEM), and also will be capable of handling higher resolutions better. (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 megabytes per second) that can be transferred across the external memory interface in one second. The number is worked out by multiplying the bus width by its memory clock speed. If it uses DDR RAM, it should be multiplied by 2 again. If it uses DDR5, multiply by ANOTHER 2x. The higher the card's 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 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 speed of the chip. The better this number, the better the card will be at 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 video card could possibly write to its local memory in one second - measured in millions of pixels per second. Pixel rate is worked out by multiplying the amount of Render Output Units 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 output rate is also dependant on lots of other factors, most notably the memory bandwidth - the lower the bandwidth is, the lower the ability to get to the maximum fill rate.
