Compare any two graphics cards:
GeForce GT 430 (OEM) vs Radeon HD 3870 512MB
IntroThe GeForce GT 430 (OEM) uses a 40 nm design. nVidia has clocked the core speed at 700 MHz. The GDDR3 memory is set to run at a speed of 900 MHz on this model. It features 96 SPUs along with 16 Texture Address Units and 4 ROPs.Compare those specs to the Radeon HD 3870 512MB, which makes use of a 55 nm design. AMD has set the core speed at 775 MHz. The GDDR3 RAM is set to run at a frequency of 900 MHz on this model. It features 320(64x5) SPUs as well as 16 Texture Address Units and 16 Rasterization Operator Units.

Power Usage and Theoretical BenchmarksPower Consumption (Max TDP)
Memory BandwidthTheoretically speaking, the Radeon HD 3870 512MB should be a lot faster than the GeForce GT 430 (OEM) overall. (explain)
Texel RateThe Radeon HD 3870 512MB is just a bit (more or less 11%) more effective at texture filtering than the GeForce GT 430 (OEM). (explain)
Pixel RateIf using a high screen resolution is important to you, then the Radeon HD 3870 512MB is superior to the GeForce GT 430 (OEM), 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 max amount of data (in units of MB per second) that can be transferred past the external memory interface in a second. It is worked out by multiplying the bus width by its memory clock speed. If the card has DDR RAM, it must be multiplied by 2 again. If it uses DDR5, multiply by 4 instead. The better the card's memory bandwidth, the faster the card will be in general. It especially helps with AA, High Dynamic Range and high resolutions. Texel Rate: Texel rate is the maximum number of texture map elements (texels) that are processed per second. This number 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 in a second. Pixel Rate: Pixel rate is the maximum amount of pixels that the graphics card could possibly record to the local memory in a second - measured in millions of pixels per second. The number is calculated by multiplying the number of Render Output Units by the the card's clock speed. ROPs (Raster Operations Pipelines - aka Render Output Units) are responsible for drawing the pixels (image) on the screen. The actual pixel rate is also dependant on many other factors, especially the memory bandwidth - the lower the bandwidth is, the lower the potential to get to the maximum fill rate.
