Compare any two graphics cards:
GeForce GT 450 (OEM) vs Radeon HD 5450
IntroThe GeForce GT 450 (OEM) makes use of a 40 nm design. nVidia has clocked the core frequency at 790 MHz. The GDDR5 RAM works at a speed of 1000 MHz on this specific card. It features 144 SPUs as well as 24 TAUs and 24 Rasterization Operator Units.Compare those specifications to the Radeon HD 5450, which features clock speeds of 650 MHz on the GPU, and 800 MHz on the 512 MB of DDR3 RAM. It features 80(16x5) SPUs along with 8 Texture Address Units and 4 ROPs.

Power Usage and Theoretical BenchmarksPower Consumption (Max TDP)
Memory BandwidthTheoretically speaking, the GeForce GT 450 (OEM) should be a lot faster than the Radeon HD 5450 overall. (explain)
Texel RateThe GeForce GT 450 (OEM) will be much (approximately 265%) more effective at AF than the Radeon HD 5450. (explain)
Pixel RateThe GeForce GT 450 (OEM) will be quite a bit (more or less 629%) better at full screen anti-aliasing than the Radeon HD 5450, and also should be capable of handling higher screen 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 data (measured in MB per second) that can be moved across the external memory interface in a second. It is worked out by multiplying the card's bus width by its memory clock speed. If it uses DDR memory, it must be multiplied by 2 once again. If it uses DDR5, multiply by ANOTHER 2x. The higher the memory bandwidth, the better the card will be in general. It especially helps with anti-aliasing, 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 number is calculated by multiplying the total texture units of the card by the core speed of the chip. The better this number, the better the graphics card will be at handling texture filtering (anisotropic filtering - AF). It is measured in millions of texels processed in one second. Pixel Rate: Pixel rate is the most pixels that the graphics card could possibly write to its local memory in a second - measured in millions of pixels per second. The number is worked out by multiplying the number of ROPs by the clock speed of the card. ROPs (Raster Operations Pipelines - sometimes also referred to as Render Output Units) are responsible for outputting the pixels (image) to the screen. The actual pixel rate also depends on quite a few other factors, especially the memory bandwidth of the card - the lower the memory bandwidth is, the lower the potential to reach the maximum fill rate.
