Compare any two graphics cards:
GeForce GT 340 1GB vs Radeon HD 4850 1GB
IntroThe GeForce GT 340 1GB makes use of a 40 nm design. nVidia has clocked the core speed at 550 MHz. The GDDR5 memory is set to run at a frequency of 850 MHz on this model. It features 96 SPUs as well as 32 Texture Address Units and 8 ROPs.Compare those specs to the Radeon HD 4850 1GB, which comes with GPU clock speed of 625 MHz, and 1024 MB of GDDR4 memory running at 993 MHz through a 256-bit bus. It also features 800(160x5) Stream Processors, 40 TAUs, and 16 ROPs.

Power Usage and Theoretical BenchmarksPower Consumption (Max TDP)
Memory BandwidthTheoretically speaking, the Radeon HD 4850 1GB should perform a bit faster than the GeForce GT 340 1GB overall. (explain)
Texel RateThe Radeon HD 4850 1GB should be much (about 42%) better at texture filtering than the GeForce GT 340 1GB. (explain)
Pixel RateThe Radeon HD 4850 1GB should be a lot (approximately 127%) more effective at FSAA than the GeForce GT 340 1GB, and will be capable of handling higher resolutions while still performing well. (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 largest amount of data (measured in megabytes per second) that can be transferred over the external memory interface within a second. The number is calculated by multiplying the bus width by the speed of its memory. If it uses DDR memory, it should be multiplied by 2 again. If it uses DDR5, multiply by ANOTHER 2x. The higher the card's memory bandwidth, the faster the card will be in general. It especially helps with anti-aliasing, High Dynamic Range and high resolutions. Texel Rate: Texel rate is the maximum number of texture map elements (texels) that can be applied in one second. This figure is calculated by multiplying the total amount of texture units of the card by the core speed of the chip. The higher this number, the better the video card will be at texture filtering (anisotropic filtering - AF). It is measured in millions of texels processed per second. Pixel Rate: Pixel rate is the most pixels that the graphics card can possibly write to the local memory in a second - measured in millions of pixels per second. The number is calculated by multiplying the amount of ROPs by the the card's clock speed. ROPs (Raster Operations Pipelines - also called Render Output Units) are responsible for outputting the pixels (image) to the screen. The actual pixel fill rate also depends on lots of other factors, especially the memory bandwidth of the card - the lower the memory bandwidth is, the lower the ability to reach the maximum fill rate.
