Compare any two graphics cards:
GeForce GTS 450 vs Radeon HD 6770 1GB
IntroThe GeForce GTS 450 uses a 40 nm design. nVidia has set the core frequency at 783 MHz. The GDDR5 RAM is set to run at a frequency of 902 MHz on this particular model. It features 192 SPUs along with 32 Texture Address Units and 16 ROPs.Compare all of that to the Radeon HD 6770 1GB, which has a GPU core clock speed of 900 MHz, and 1024 MB of GDDR5 RAM running at 1050 MHz through a 128-bit bus. It also is made up of 800 SPUs, 40 TAUs, and 16 Raster Operation Units.

Power Usage and Theoretical BenchmarksPower Consumption (Max TDP)
Memory BandwidthTheoretically speaking, the Radeon HD 6770 1GB will be 16% quicker than the GeForce GTS 450 in general, because of its higher data rate. (explain)
Texel RateThe Radeon HD 6770 1GB will be a lot (more or less 44%) better at texture filtering than the GeForce GTS 450. (explain)
Pixel RateThe Radeon HD 6770 1GB will be a small bit (more or less 15%) faster with regards to FSAA than the GeForce GTS 450, and able to handle higher resolutions without losing too much performance. (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: Bandwidth is the max amount of data (in units of megabytes per second) that can be moved across the external memory interface in one second. It is worked out by multiplying the bus width by the speed of its memory. If the card has DDR RAM, it must be multiplied by 2 once again. If DDR5, multiply by ANOTHER 2x. The better the card's memory bandwidth, the faster 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 number of texture map elements (texels) that can be processed per second. This figure is calculated by multiplying the total amount of texture units by the core 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 in one second. Pixel Rate: Pixel rate is the most pixels that the graphics card can possibly write to the local memory per second - measured in millions of pixels per second. The number is worked out by multiplying the amount of colour ROPs by the the core clock speed. ROPs (Raster Operations Pipelines - also sometimes called Render Output Units) are responsible for drawing the pixels (image) on the screen. The actual pixel fill rate is also dependant on lots of other factors, most notably the memory bandwidth - the lower the memory bandwidth is, the lower the potential to get to the maximum fill rate.
