Compare any two graphics cards:
GeForce GT 340 1GB vs Radeon HD 3850 512MB
IntroThe GeForce GT 340 1GB makes use of a 40 nm design. nVidia has set the core frequency at 550 MHz. The GDDR5 memory works at a frequency of 850 MHz on this particular card. It features 96 SPUs as well as 32 Texture Address Units and 8 ROPs.Compare those specs to the Radeon HD 3850 512MB, which makes use of a 55 nm design. AMD has set the core frequency at 668 MHz. The GDDR3 RAM is set to run at a frequency of 828 MHz on this specific card. It features 320(64x5) SPUs as well as 16 TAUs and 16 Rasterization Operator Units.

Power Usage and Theoretical BenchmarksPower Consumption (Max TDP)
Memory BandwidthTheoretically speaking, the GeForce GT 340 1GB should be a small bit faster than the Radeon HD 3850 512MB in general. (explain)
Texel RateThe GeForce GT 340 1GB will be quite a bit (more or less 65%) more effective at texture filtering than the Radeon HD 3850 512MB. (explain)
Pixel RateIf using a high resolution is important to you, then the Radeon HD 3850 512MB is superior to the GeForce GT 340 1GB, 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 (measured in MB per second) that can be transported past the external memory interface in a second. It's calculated by multiplying the interface width by the speed of its memory. If the card has DDR memory, it should be multiplied by 2 once again. If DDR5, multiply by 4 instead. The higher the bandwidth is, 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 can be processed per second. This number is calculated by multiplying the total texture units of the card by the core clock speed of the chip. The better this number, the better the video card will be at texture filtering (anisotropic filtering - AF). It is measured in millions of texels in one second. Pixel Rate: Pixel rate is the maximum amount of pixels that the graphics card can possibly record to the local memory per second - measured in millions of pixels per second. The figure is calculated by multiplying the number of ROPs by the the core 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 many other factors, most notably the memory bandwidth of the card - the lower the bandwidth is, the lower the potential to reach the max fill rate.
