Compare any two graphics cards:
GeForce GTX 550 Ti vs Radeon HD 6450 (OEM) 1GB
IntroThe GeForce GTX 550 Ti comes with core clock speeds of 900 MHz on the GPU, and 1026 MHz on the 1024 MB of GDDR5 memory. It features 192 SPUs along with 32 TAUs and 24 Rasterization Operator Units.
Compare all of that to the Radeon HD 6450 (OEM) 1GB, which makes use of a 40 nm design. ATi has set the core speed at 750 MHz. The GDDR5 memory works at a speed of 900 MHz on this card. It features 160 SPUs as well as 8 TAUs and 4 ROPs.

Power Usage and Theoretical Benchmarks
Power Consumption (Max TDP)
In theory, the GeForce GTX 550 Ti is 242% quicker than the Radeon HD 6450 (OEM) 1GB in general, because of its higher bandwidth. (explain)
Texel RateThe GeForce GTX 550 Ti should be quite a bit (more or less 380%) better at AF than the Radeon HD 6450 (OEM) 1GB. (explain)
Pixel RateIf running with a high screen resolution is important to you, then the GeForce GTX 550 Ti is a better choice, by far. (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 data (counted in MB per second) that can be transported past the external memory interface within a second. The number is worked out by multiplying the bus width by the speed of its memory. If the card has DDR memory, it must be multiplied by 2 once again. If it uses DDR5, multiply by 4 instead. The higher the card's memory bandwidth, 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 number of texture map elements (texels) that can be processed per second. This figure is worked out by multiplying the total number of texture units of the card by the core clock speed of the chip. The higher this number, the better the video card will be at handling texture filtering (anisotropic filtering - AF). It is measured in millions of texels applied per second.
Pixel Rate: Pixel rate is the maximum amount of pixels that the graphics card can possibly write to the local memory in a second - measured in millions of pixels per second. Pixel rate is worked out by multiplying the amount of colour ROPs by the the core speed of the card. ROPs (Raster Operations Pipelines - aka Render Output Units) are responsible for outputting the pixels (image) to the screen. The actual pixel output rate also depends on lots of other factors, especially the memory bandwidth - the lower the bandwidth is, the lower the potential to get to the max fill rate.
