Compare any two graphics cards:
GeForce GTX 550 Ti vs Radeon HD 6450 (OEM) 1GB
IntroThe GeForce GTX 550 Ti features a clock frequency of 900 MHz and a GDDR5 memory speed of 1026 MHz. It also features a 192-bit bus, and uses a 40 nm design. It is made up of 192 SPUs, 32 Texture Address Units, and 24 Raster Operation Units.
Compare those specs to the Radeon HD 6450 (OEM) 1GB, which has core clock speeds of 750 MHz on the GPU, and 900 MHz on the 1024 MB of GDDR5 memory. It features 160 SPUs along with 8 Texture Address Units and 4 Rasterization Operator Units.

Power Usage and Theoretical Benchmarks
Power Consumption (Max TDP)
Performance-wise, the GeForce GTX 550 Ti should theoretically be a lot superior to the Radeon HD 6450 (OEM) 1GB in general. (explain)
Texel RateThe GeForce GTX 550 Ti is much (about 380%) better at texture filtering than the Radeon HD 6450 (OEM) 1GB. (explain)
Pixel RateThe GeForce GTX 550 Ti is a lot (approximately 620%) faster with regards to AA than the Radeon HD 6450 (OEM) 1GB, and also able to handle higher resolutions without slowing down too much. (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.
Please note that the price comparisons are based on search keywords - sometimes it might show cards with very similar names that are not exactly the same as the one chosen in the comparison. We do try to filter out the wrong results as best we can, though.
Memory Bandwidth: Memory bandwidth is the max amount of information (counted in MB per second) that can be transferred across the external memory interface in a second. It is calculated by multiplying the card's interface width by its memory speed. If the card has DDR type memory, it should be multiplied by 2 again. If it uses DDR5, multiply by ANOTHER 2x. The better the card's memory bandwidth, the better the card will be in general. It especially helps with anti-aliasing, HDR and higher screen resolutions.
Texel Rate: Texel rate is the maximum number 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 speed of the chip. The higher the texel rate, the better the graphics card will be at texture filtering (anisotropic filtering - AF). It is measured in millions of texels applied per second.
Pixel Rate: Pixel rate is the most pixels that the graphics chip could possibly record to the local memory in a second - measured in millions of pixels per second. The number is worked out by multiplying the number of Render Output Units by the clock speed of the card. ROPs (Raster Operations Pipelines - also sometimes called Render Output Units) are responsible for drawing the pixels (image) on the screen. The actual pixel rate also depends on quite a few other factors, especially the memory bandwidth of the card - the lower the bandwidth is, the lower the potential to get to the maximum fill rate.
