Compare any two graphics cards:
GeForce 8600 GT 1GB DDR2 vs Radeon HD 4650 512MB
IntroThe GeForce 8600 GT 1GB DDR2 comes with clock speeds of 540 MHz on the GPU, and 400 MHz on the 1024 MB of DDR2 memory. It features 32 SPUs as well as 16 TAUs and 8 ROPs.Compare those specs to the Radeon HD 4650 512MB, which makes use of a 55 nm design. AMD has set the core speed at 600 MHz. The DDR2 RAM runs at a frequency of 500 MHz on this specific model. It features 320(64x5) SPUs along with 32 TAUs and 8 ROPs.

Power Usage and Theoretical BenchmarksPower Consumption (Max TDP)
Memory BandwidthThe Radeon HD 4650 512MB should theoretically be quite a bit faster than the GeForce 8600 GT 1GB DDR2 overall. (explain)
Texel RateThe Radeon HD 4650 512MB should be quite a bit (more or less 122%) more effective at texture filtering than the GeForce 8600 GT 1GB DDR2. (explain)
Pixel RateIf running with a high screen resolution is important to you, then the Radeon HD 4650 512MB is the winner, though not 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 data (measured in MB per second) that can be transferred past the external memory interface within a second. It's worked out by multiplying the card's interface width by the speed of its memory. If it uses DDR memory, the result should be multiplied by 2 once 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 higher screen resolutions. Texel Rate: Texel rate is the maximum amount of texture map elements (texels) that are processed in one second. This is worked out by multiplying the total amount of texture units of the card 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 per second. Pixel Rate: Pixel rate is the most pixels the video card could possibly write to its local memory in one second - measured in millions of pixels per second. The figure is worked out by multiplying the amount of Raster Operations Pipelines by the the core clock speed. ROPs (Raster Operations Pipelines - also called 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 of the card - the lower the memory bandwidth is, the lower the potential to get to the max fill rate.
