Compare any two graphics cards:
GeForce GTX 660 vs Radeon HD 6450 (OEM) 1GB
IntroThe GeForce GTX 660 makes use of a 28 nm design. nVidia has set the core speed at 980 MHz. The GDDR5 RAM works at a frequency of 1502 MHz on this card. It features 960 SPUs along with 80 TAUs and 24 Rasterization Operator Units.
Compare that to the Radeon HD 6450 (OEM) 1GB, which comes with GPU core speed of 750 MHz, and 1024 MB of GDDR5 RAM set to run at 900 MHz through a 64-bit bus. It also features 160 Stream Processors, 8 Texture Address Units, and 4 ROPs.

Power Usage and Theoretical Benchmarks
Power Consumption (Max TDP)
Performance-wise, the GeForce GTX 660 should in theory be much superior to the Radeon HD 6450 (OEM) 1GB in general. (explain)
Texel RateThe GeForce GTX 660 should be quite a bit (about 1207%) faster with regards to texture filtering than the Radeon HD 6450 (OEM) 1GB. (explain)
Pixel RateThe GeForce GTX 660 is much (more or less 684%) faster with regards to FSAA than the Radeon HD 6450 (OEM) 1GB, and able to handle 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 ComparisonPlease note that the price comparisons are based on search keywords, and might not be the exact same card listed on this page. We have no control over the accuracy of their search results.
Memory Bandwidth: Bandwidth is the max amount of data (counted in megabytes per second) that can be transferred past the external memory interface in one second. It is worked out by multiplying the card's interface width by its memory speed. In the case of DDR type memory, the result should be multiplied by 2 once 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, High Dynamic Range and higher screen resolutions.
Texel Rate: Texel rate is the maximum texture map elements (texels) that are applied in one second. This figure is worked out 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 applied in a second.
Pixel Rate: Pixel rate is the most pixels that the graphics card could possibly write to the local memory per second - measured in millions of pixels per second. The number is calculated by multiplying the number of Render Output Units by the the card's clock speed. ROPs (Raster Operations Pipelines - also called Render Output Units) are responsible for outputting the pixels (image) to the screen. The actual pixel fill rate is also dependant on quite a few other factors, most notably the memory bandwidth of the card - the lower the bandwidth is, the lower the ability to reach the max fill rate.
