Compare any two graphics cards:
GeForce GTX 550 Ti vs Radeon HD 4670 1GB
IntroThe GeForce GTX 550 Ti makes use of a 40 nm design. nVidia has set the core frequency at 900 MHz. The GDDR5 memory works at a frequency of 1026 MHz on this specific card. It features 192 SPUs along with 32 TAUs and 24 Rasterization Operator Units.Compare those specs to the Radeon HD 4670 1GB, which features a clock speed of 750 MHz and a GDDR4/GDDR3/DDR3/DDR2 memory speed of 1100 MHz. It also uses a 128-bit bus, and makes use of a 55 nm design. It is made up of 320(64x5) SPUs, 32 Texture Address Units, and 8 ROPs.

Power Usage and Theoretical BenchmarksPower Consumption (Max TDP)
Memory BandwidthThe GeForce GTX 550 Ti should in theory perform quite a bit faster than the Radeon HD 4670 1GB overall. (explain)
Texel RateThe GeForce GTX 550 Ti is a bit (about 20%) faster with regards to AF than the Radeon HD 4670 1GB. (explain)
Pixel RateIf running with a high resolution is important to you, then the GeForce GTX 550 Ti is the winner, 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 Comparison

Display Specifications
Memory Bandwidth: Memory bandwidth is the largest amount of information (counted in megabytes per second) that can be moved past the external memory interface in a second. It is worked out by multiplying the card's bus width by its memory speed. If the card has DDR memory, 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 AA, HDR and high resolutions. Texel Rate: Texel rate is the maximum number of texture map elements (texels) that are processed per second. This is worked out by multiplying the total amount of texture units by the core speed of the chip. The better this number, the better the graphics 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 the graphics card can possibly write to its local memory in one second - measured in millions of pixels per second. The number is worked out by multiplying the amount of Raster Operations Pipelines by the the card's clock speed. ROPs (Raster Operations Pipelines - aka Render Output Units) are responsible for drawing the pixels (image) on the screen. The actual pixel output rate is also dependant on quite a few other factors, especially the memory bandwidth of the card - the lower the bandwidth is, the lower the ability to reach the maximum fill rate.
