Compare any two graphics cards:
GeForce GT 320 vs Radeon HD 4650 1GB
IntroThe GeForce GT 320 has core clock speeds of 540 MHz on the GPU, and 790 MHz on the 1024 MB of GDDR3 memory. It features 72 SPUs as well as 24 TAUs and 8 ROPs.Compare those specs to the Radeon HD 4650 1GB, which features clock speeds of 600 MHz on the GPU, and 700 MHz on the 1024 MB of GDDR3 RAM. It features 320(64x5) SPUs along with 32 TAUs and 8 ROPs.

Power Usage and Theoretical BenchmarksPower Consumption (Max TDP)
Memory BandwidthPerformance-wise, the GeForce GT 320 should in theory be a little bit better than the Radeon HD 4650 1GB overall. (explain)
Texel RateThe Radeon HD 4650 1GB should be quite a bit (about 48%) faster with regards to AF than the GeForce GT 320. (explain)
Pixel RateIf using a high screen resolution is important to you, then the Radeon HD 4650 1GB is superior to the GeForce GT 320, not by a very large margin though. (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 data (measured in MB per second) that can be moved over the external memory interface within a second. The number is calculated by multiplying the card's bus width by the speed of its memory. If the card has DDR type RAM, the result should be multiplied by 2 again. If DDR5, multiply by ANOTHER 2x. The higher the memory bandwidth, the better 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 are applied per second. This is calculated by multiplying the total number of texture units by the core clock 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 applied in one second. Pixel Rate: Pixel rate is the maximum number of pixels that the graphics card 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 number of colour ROPs by the the card's clock speed. ROPs (Raster Operations Pipelines - also sometimes called Render Output Units) are responsible for outputting the pixels (image) to the screen. The actual pixel output rate also depends on quite a few other factors, especially the memory bandwidth - the lower the bandwidth is, the lower the ability to get to the max fill rate.
