Compare any two graphics cards:
GeForce GT 340 1GB vs Radeon HD 3850 1GB
IntroThe GeForce GT 340 1GB makes use of a 40 nm design. nVidia has clocked the core speed at 550 MHz. The GDDR5 RAM is set to run at a speed of 850 MHz on this specific card. It features 96 SPUs along with 32 Texture Address Units and 8 Rasterization Operator Units.Compare those specifications to the Radeon HD 3850 1GB, which makes use of a 55 nm design. AMD has clocked the core speed at 668 MHz. The GDDR3 RAM runs at a speed of 828 MHz on this model. It features 320(64x5) SPUs as well as 16 Texture Address Units and 16 ROPs.

Power Usage and Theoretical BenchmarksPower Consumption (Max TDP)
Memory BandwidthTheoretically speaking, the GeForce GT 340 1GB will be 3% faster than the Radeon HD 3850 1GB in general, because of its greater data rate. (explain)
Texel RateThe GeForce GT 340 1GB is quite a bit (approximately 65%) better at texture filtering than the Radeon HD 3850 1GB. (explain)
Pixel RateIf using lots of anti-aliasing is important to you, then the Radeon HD 3850 1GB is superior to the GeForce GT 340 1GB, by far. (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 maximum amount of information (counted in MB per second) that can be transported over the external memory interface in one second. The number is calculated by multiplying the bus width by its memory speed. In the case of DDR memory, the result should be multiplied by 2 again. If DDR5, multiply by 4 instead. The better the card's memory bandwidth, the better 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 amount of texture map elements (texels) that are applied per second. This is calculated by multiplying the total texture units by the core speed of the chip. The higher this number, the better the 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 number of pixels that the graphics chip could possibly record to its local memory in one second - measured in millions of pixels per second. The figure is worked out by multiplying the amount of ROPs by the the card's clock speed. ROPs (Raster Operations Pipelines - aka Render Output Units) are responsible for outputting the pixels (image) to the screen. The actual pixel fill rate is also dependant on lots of other factors, most notably the memory bandwidth - the lower the bandwidth is, the lower the ability to reach the maximum fill rate.
