Compare any two graphics cards:
GeForce 8600 GTS vs Radeon HD 4670 1GB
IntroThe GeForce 8600 GTS has a clock frequency of 675 MHz and a GDDR3 memory frequency of 1000 MHz. It also uses a 128-bit bus, and makes use of a 80 nm design. It features 32 SPUs, 16 Texture Address Units, and 8 Raster Operation Units.Compare all that to the Radeon HD 4670 1GB, which comes with core clock speeds of 750 MHz on the GPU, and 1100 MHz on the 1024 MB of GDDR4/GDDR3/DDR3/DDR2 memory. It features 320(64x5) SPUs as well as 32 TAUs and 8 Rasterization Operator Units.

Power Usage and Theoretical BenchmarksPower Consumption (Max TDP)
Memory BandwidthAs far as performance goes, the Radeon HD 4670 1GB should theoretically be just a bit superior to the GeForce 8600 GTS in general. (explain)
Texel RateThe Radeon HD 4670 1GB should be a lot (about 122%) more effective at AF than the GeForce 8600 GTS. (explain)
Pixel RateThe Radeon HD 4670 1GB is a little bit (about 11%) more effective at full screen anti-aliasing than the GeForce 8600 GTS, and also will be able to handle higher screen resolutions without losing too much performance. (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 megabytes per second) that can be moved across the external memory interface in a second. It's calculated by multiplying the card's interface width by its memory clock speed. In the case of DDR memory, the result should be multiplied by 2 once again. If it uses DDR5, multiply by 4 instead. The higher the card's memory bandwidth, the better the card will be in general. It especially helps with anti-aliasing, HDR and higher screen resolutions. Texel Rate: Texel rate is the maximum texture map elements (texels) that can be applied per second. This is worked out by multiplying the total amount of texture units 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 applied in one second. Pixel Rate: Pixel rate is the maximum amount of pixels the video card can possibly record to its local memory per second - measured in millions of pixels per second. The number is worked out by multiplying the amount of Raster Operations Pipelines by the clock speed of the card. ROPs (Raster Operations Pipelines - also called Render Output Units) are responsible for filling the screen with pixels (the image). The actual pixel fill rate also depends on lots of other factors, most notably the memory bandwidth of the card - the lower the bandwidth is, the lower the potential to get to the maximum fill rate.
