Compare any two graphics cards:
GeForce GT 240 GDDR5 vs Radeon HD 5450
IntroThe GeForce GT 240 GDDR5 features a GPU core clock speed of 550 MHz, and the 512 MB of GDDR5 RAM is set to run at 850 MHz through a 128-bit bus. It also features 96 Stream Processors, 32 Texture Address Units, and 8 ROPs.Compare all of that to the Radeon HD 5450, which uses a 40 nm design. AMD has set the core speed at 650 MHz. The DDR3 memory works at a speed of 800 MHz on this specific 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 GT 240 GDDR5 should theoretically be much superior to the Radeon HD 5450 in general. (explain)
Texel RateThe GeForce GT 240 GDDR5 should be quite a bit (about 238%) more effective at anisotropic filtering than the Radeon HD 5450. (explain)
Pixel RateThe GeForce GT 240 GDDR5 will be a lot (more or less 69%) faster with regards to AA than the Radeon HD 5450, and also will be able to handle higher resolutions more effectively. (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 information (measured in megabytes per second) that can be transferred over the external memory interface within a second. It's worked out by multiplying the interface width by its memory clock speed. In the case of DDR memory, it must be multiplied by 2 once again. If DDR5, multiply by ANOTHER 2x. The higher the memory bandwidth, the better the card will be in general. It especially helps with AA, High Dynamic Range and higher screen resolutions. Texel Rate: Texel rate is the maximum number of texture map elements (texels) that are applied in one second. This figure is calculated by multiplying the total amount of texture units by the core clock speed of the chip. The better the texel rate, the better the graphics card will be at handling texture filtering (anisotropic filtering - AF). It is measured in millions of texels processed per second. Pixel Rate: Pixel rate is the maximum number of pixels the graphics card can possibly record to the local memory per second - measured in millions of pixels per second. The number is worked out by multiplying the amount of ROPs by the clock speed of the card. ROPs (Raster Operations Pipelines - also sometimes called Render Output Units) are responsible for outputting the pixels (image) to the screen. The actual pixel rate also depends on many other factors, most notably the memory bandwidth - the lower the bandwidth is, the lower the ability to reach the maximum fill rate.
