Compare any two graphics cards:
GeForce GTX 480 vs Radeon HD 6450 (OEM) 1GB
IntroThe GeForce GTX 480 comes with a GPU core clock speed of 700 MHz, and the 1536 MB of GDDR5 RAM runs at 924 MHz through a 384-bit bus. It also features 480 Stream Processors, 60 Texture Address Units, and 48 ROPs.
Compare those specs to the Radeon HD 6450 (OEM) 1GB, which makes use of a 40 nm design. ATi has clocked the core frequency at 750 MHz. The GDDR5 RAM runs at a speed of 900 MHz on this model. It features 160 SPUs as well as 8 TAUs and 4 Rasterization Operator Units.

Power Usage and Theoretical Benchmarks
Power Consumption (Max TDP)
The GeForce GTX 480 should in theory be quite a bit faster than the Radeon HD 6450 (OEM) 1GB in general. (explain)
Texel RateThe GeForce GTX 480 is a lot (more or less 600%) faster with regards to AF than the Radeon HD 6450 (OEM) 1GB. (explain)
Pixel RateIf using lots of anti-aliasing is important to you, then the GeForce GTX 480 is superior to the Radeon HD 6450 (OEM) 1GB, 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 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: Memory bandwidth is the max amount of information (counted in megabytes per second) that can be transferred past the external memory interface in one second. The number is worked out by multiplying the bus width by the speed of its memory. In the case of DDR type memory, it should be multiplied by 2 again. If DDR5, multiply by ANOTHER 2x. The better the card's 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 amount of texture map elements (texels) that are applied in one second. This is calculated by multiplying the total amount of texture units by the core clock speed of the chip. The higher the texel rate, the better the card will be at texture filtering (anisotropic filtering - AF). It is measured in millions of texels applied in one second.
Pixel Rate: Pixel rate is the maximum number of pixels the video card can possibly record to the local memory per second - measured in millions of pixels per second. Pixel rate is calculated by multiplying the number of Raster Operations Pipelines by the the core clock speed. ROPs (Raster Operations Pipelines - also called Render Output Units) are responsible for outputting the pixels (image) to the screen. The actual pixel output rate is also dependant on many other factors, most notably the memory bandwidth - the lower the bandwidth is, the lower the potential to reach the max fill rate.
