Compare any two graphics cards:
GeForce GTX 580 vs Radeon HD 5450
IntroThe GeForce GTX 580 features a core clock speed of 772 MHz and a GDDR5 memory speed of 1002 MHz. It also makes use of a 384-bit bus, and uses a 40 nm design. It is made up of 512 SPUs, 64 TAUs, and 48 ROPs.Compare those specs to the Radeon HD 5450, which uses a 40 nm design. AMD has set the core speed at 650 MHz. The DDR3 memory is set to run at a frequency of 800 MHz on this particular model. It features 80(16x5) SPUs along with 8 TAUs and 4 Rasterization Operator Units.

Power Usage and Theoretical BenchmarksPower Consumption (Max TDP)
Memory BandwidthPerformance-wise, the GeForce GTX 580 should theoretically be a lot superior to the Radeon HD 5450 overall. (explain)
Texel RateThe GeForce GTX 580 should be quite a bit (more or less 850%) more effective at texture filtering than the Radeon HD 5450. (explain)
Pixel RateIf using high levels of AA is important to you, then the GeForce GTX 580 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: Bandwidth is the largest amount of data (counted in megabytes per second) that can be moved past the external memory interface in one second. It is worked out by multiplying the interface width by the speed of its memory. If the card has DDR memory, it should be multiplied by 2 once again. If it uses DDR5, multiply by 4 instead. The better the memory bandwidth, the faster the card will be in general. It especially helps with anti-aliasing, HDR and higher screen resolutions. Texel Rate: Texel rate is the maximum amount of texture map elements (texels) that can be processed per second. This is calculated by multiplying the total texture units of the card by the core clock speed of the chip. The better the texel rate, the better the card will be at handling texture filtering (anisotropic filtering - AF). It is measured in millions of texels applied in one second. Pixel Rate: Pixel rate is the maximum number of pixels the graphics card could possibly write to the local memory in one second - measured in millions of pixels per second. The number is worked out by multiplying the number of ROPs by the the core clock speed. ROPs (Raster Operations Pipelines - also called 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.
