Compare any two graphics cards:
GeForce GTX 550 Ti vs Radeon HD 6450 (OEM) 1GB
IntroThe GeForce GTX 550 Ti has a clock speed of 900 MHz and a GDDR5 memory frequency of 1026 MHz. It also features a 192-bit memory bus, and uses a 40 nm design. It features 192 SPUs, 32 TAUs, and 24 Raster Operation Units.
Compare those specs to the Radeon HD 6450 (OEM) 1GB, which makes use of a 40 nm design. ATi has set the core frequency at 750 MHz. The GDDR5 RAM works at a speed of 900 MHz on this card. It features 160 SPUs along with 8 TAUs and 4 ROPs.

Power Usage and Theoretical Benchmarks
Power Consumption (Max TDP)
Theoretically, the GeForce GTX 550 Ti should perform much faster than the Radeon HD 6450 (OEM) 1GB in general. (explain)
Texel RateThe GeForce GTX 550 Ti will be a lot (approximately 380%) better at anisotropic filtering than the Radeon HD 6450 (OEM) 1GB. (explain)
Pixel RateIf running with high levels of AA is important to you, then the GeForce GTX 550 Ti 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 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 largest amount of information (measured in MB per second) that can be moved past the external memory interface in a second. The number is calculated by multiplying the interface width by its memory speed. In the case of DDR RAM, the result should be multiplied by 2 once again. If it uses DDR5, multiply by 4 instead. The higher the memory bandwidth, the faster the card will be in general. It especially helps with anti-aliasing, High Dynamic Range and high resolutions.
Texel Rate: Texel rate is the maximum number of texture map elements (texels) that are processed per second. This figure is worked out by multiplying the total number of texture units of the card by the core 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 per second.
Pixel Rate: Pixel rate is the maximum amount of pixels the video card can possibly write to its local memory in a second - measured in millions of pixels per second. Pixel rate is calculated by multiplying the amount of colour ROPs 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 reach the max fill rate.
