Compare any two graphics cards:
GeForce GTX 460 SE vs Radeon HD 6450 (OEM) 1GB
IntroThe GeForce GTX 460 SE makes use of a 40 nm design. nVidia has clocked the core speed at 650 MHz. The GDDR5 memory runs at a speed of 850 MHz on this model. It features 288 SPUs along with 48 Texture Address Units and 32 ROPs.Compare that to the Radeon HD 6450 (OEM) 1GB, which comes with GPU clock speed of 750 MHz, and 1024 MB of GDDR5 memory running at 900 MHz through a 64-bit bus. It also is comprised of 160 Stream Processors, 8 Texture Address Units, and 4 ROPs.

Power Usage and Theoretical BenchmarksPower Consumption (Max TDP)
Memory BandwidthTheoretically, the GeForce GTX 460 SE should perform a lot faster than the Radeon HD 6450 (OEM) 1GB overall. (explain)
Texel RateThe GeForce GTX 460 SE is much (approximately 420%) more effective at anisotropic filtering than the Radeon HD 6450 (OEM) 1GB. (explain)
Pixel RateIf using a high screen resolution is important to you, then the GeForce GTX 460 SE is the winner, by a large margin. (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 (measured in MB per second) that can be transported over the external memory interface in one second. It's calculated by multiplying the interface width by its memory clock speed. In the case of DDR RAM, the result should be multiplied by 2 again. If it uses DDR5, multiply by 4 instead. The better the bandwidth is, the better the card will be in general. It especially helps with AA, High Dynamic Range and high resolutions. Texel Rate: Texel rate is the maximum texture map elements (texels) that can be applied per second. This is calculated by multiplying the total number of texture units of the card by the core speed of the chip. The higher 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. Pixel rate is worked out by multiplying the number of Render Output Units by the the card's clock speed. ROPs (Raster Operations Pipelines - aka Render Output Units) are responsible for filling the screen with pixels (the image). The actual pixel fill rate also depends on quite a few other factors, especially the memory bandwidth - the lower the memory bandwidth is, the lower the ability to get to the max fill rate.
