Compare any two graphics cards:
GeForce GTS 450 1GB vs Radeon HD 3470 256MB
IntroThe GeForce GTS 450 1GB features core speeds of 783 MHz on the GPU, and 902 MHz on the 1024 MB of GDDR5 RAM. It features 192 SPUs as well as 32 Texture Address Units and 16 Rasterization Operator Units.Compare those specs to the Radeon HD 3470 256MB, which makes use of a 55 nm design. AMD has set the core frequency at 800 MHz. The DDR2 memory runs at a speed of 950 MHz on this card. It features 40(8x5) SPUs along with 4 Texture Address Units and 4 ROPs.

Power Usage and Theoretical BenchmarksMemory BandwidthThe GeForce GTS 450 1GB should theoretically perform quite a bit faster than the Radeon HD 3470 256MB overall. (explain)
Texel RateThe GeForce GTS 450 1GB will be quite a bit (approximately 683%) faster with regards to texture filtering than the Radeon HD 3470 256MB. (explain)
Pixel RateThe GeForce GTS 450 1GB will be quite a bit (approximately 292%) better at AA than the Radeon HD 3470 256MB, and also capable of handling higher screen resolutions better. (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 (measured in megabytes per second) that can be transported past the external memory interface in a second. It is worked out by multiplying the bus width by its memory speed. If the card has DDR RAM, it must be multiplied by 2 once again. If it uses DDR5, multiply by 4 instead. The higher the bandwidth is, the faster the card will be in general. It especially helps with anti-aliasing, HDR and higher screen resolutions. Texel Rate: Texel rate is the maximum texture map elements (texels) that can be processed per second. This number is calculated by multiplying the total amount of texture units by the core speed of the chip. The higher this number, 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 maximum amount of pixels that the graphics chip could possibly record to the local memory in one second - measured in millions of pixels per second. The figure is calculated by multiplying the amount of ROPs by the the core speed of the card. ROPs (Raster Operations Pipelines - sometimes also referred to as Render Output Units) are responsible for outputting the pixels (image) to the screen. The actual pixel output rate is also dependant on many other factors, especially the memory bandwidth - the lower the memory bandwidth is, the lower the ability to reach the max fill rate.
