Compare any two graphics cards:
GeForce GT 220 GDDR3 vs Radeon HD 3690/3830
IntroThe GeForce GT 220 GDDR3 makes use of a 40 nm design. nVidia has clocked the core speed at 625 MHz. The GDDR3 memory works at a frequency of 1012 MHz on this particular card. It features 48 SPUs as well as 16 Texture Address Units and 8 ROPs.Compare those specifications to the Radeon HD 3690/3830, which makes use of a 55 nm design. AMD has set the core speed at 668 MHz. The GDDR3 RAM is set to run at a frequency of 828 MHz on this particular model. It features 320(64x5) SPUs along with 16 TAUs and 16 Rasterization Operator Units.

Power Usage and Theoretical BenchmarksPower Consumption (Max TDP)
Memory BandwidthThe GeForce GT 220 GDDR3, in theory, should be much faster than the Radeon HD 3690/3830 in general. (explain)
Texel RateThe Radeon HD 3690/3830 will be a small bit (approximately 7%) more effective at AF than the GeForce GT 220 GDDR3. (explain)
Pixel RateIf using a high screen resolution is important to you, then the Radeon HD 3690/3830 is superior to the GeForce GT 220 GDDR3, 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 megabytes per second) that can be moved past the external memory interface in a second. The number is worked out by multiplying the interface width by the speed of its memory. If the card has DDR memory, the result should be multiplied by 2 once again. If it uses DDR5, multiply by 4 instead. The higher the 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 amount of texture map elements (texels) that can be processed per second. This figure 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 graphics card will be at texture filtering (anisotropic filtering - AF). It is measured in millions of texels processed in one second. Pixel Rate: Pixel rate is the most pixels the graphics card can possibly record to its local memory in a second - measured in millions of pixels per second. The figure is worked out by multiplying the amount of ROPs by the clock speed of the card. ROPs (Raster Operations Pipelines - sometimes also referred to as Render Output Units) are responsible for drawing the pixels (image) on the screen. The actual pixel output rate also depends on many other factors, especially the memory bandwidth - the lower the memory bandwidth is, the lower the potential to get to the max fill rate.
