Compare any two graphics cards:
GeForce GTX 470 vs Radeon HD 6450 (OEM) 1GB
IntroThe GeForce GTX 470 features a core clock speed of 607 MHz and a GDDR5 memory frequency of 837 MHz. It also features a 320-bit memory bus, and uses a 40 nm design. It features 448 SPUs, 56 Texture Address Units, and 40 ROPs.Compare those specs to the Radeon HD 6450 (OEM) 1GB, which uses a 40 nm design. AMD has clocked the core speed at 750 MHz. The GDDR5 memory works at a frequency of 900 MHz on this model. It features 160 SPUs as well as 8 TAUs and 4 ROPs.

Power Usage and Theoretical BenchmarksPower Consumption (Max TDP)
Memory BandwidthPerformance-wise, the GeForce GTX 470 should theoretically be much better than the Radeon HD 6450 (OEM) 1GB in general. (explain)
Texel RateThe GeForce GTX 470 should be a lot (approximately 467%) faster with regards to texture filtering than the Radeon HD 6450 (OEM) 1GB. (explain)
Pixel RateIf using lots of anti-aliasing is important to you, then the GeForce GTX 470 is a better choice, and very much so. (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 max amount of data (in units of MB per second) that can be transferred past the external memory interface in one second. It's calculated by multiplying the interface width by its memory clock speed. If it uses DDR type memory, it must be multiplied by 2 again. If DDR5, multiply by 4 instead. The better the card's memory bandwidth, the faster the card will be in general. It especially helps with AA, HDR and high resolutions. Texel Rate: Texel rate is the maximum texture map elements (texels) that are 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 this number, the better the video card will be at handling 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 graphics card can possibly record to the local memory in one second - measured in millions of pixels per second. The number is worked out by multiplying the number of Render Output Units by the the card's clock speed. 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 output rate also depends on quite a few other factors, most notably the memory bandwidth - the lower the memory bandwidth is, the lower the potential to get to the max fill rate.
