Compare any two graphics cards:
GeForce 8600 GTS vs Radeon HD 5570
IntroThe GeForce 8600 GTS comes with core speeds of 675 MHz on the GPU, and 1000 MHz on the 512 MB of GDDR3 memory. It features 32 SPUs as well as 16 TAUs and 8 ROPs.
Compare all of that to the Radeon HD 5570, which uses a 40 nm design. ATi has clocked the core frequency at 650 MHz. The DDR3 RAM runs at a speed of 900 MHz on this particular model. It features 400(80x5) SPUs as well as 20 Texture Address Units and 8 ROPs.

Power Usage and Theoretical Benchmarks
Power Consumption (Max TDP)
The GeForce 8600 GTS, in theory, should be a small bit faster than the Radeon HD 5570 in general. (explain)
Texel RateThe Radeon HD 5570 will be just a bit (approximately 20%) faster with regards to texture filtering than the GeForce 8600 GTS. (explain)
Pixel RateIf running with high levels of AA is important to you, then the GeForce 8600 GTS is a better choice, 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 ComparisonPlease note that the price comparisons are based on search keywords, and might not be the exact same card listed on this page. We have no control over the accuracy of their search results.
Memory Bandwidth: Bandwidth is the largest amount of data (counted in MB per second) that can be moved over the external memory interface in one second. It's worked out by multiplying the bus width by its memory clock speed. If it uses DDR RAM, the result should be multiplied by 2 once again. If DDR5, multiply by ANOTHER 2x. The better the memory bandwidth, the faster the card will be in general. It especially helps with anti-aliasing, High Dynamic Range and higher screen resolutions.
Texel Rate: Texel rate is the maximum number of texture map elements (texels) that are applied in one second. This number is worked out by multiplying the total texture units of the card by the core speed of the chip. The higher this number, the better the card will be at handling texture filtering (anisotropic filtering - AF). It is measured in millions of texels processed in one second.
Pixel Rate: Pixel rate is the most pixels that the graphics card could possibly record to its local memory in one second - measured in millions of pixels per second. The number is calculated by multiplying the number of ROPs by the the card's clock speed. ROPs (Raster Operations Pipelines - aka Render Output Units) are responsible for outputting the pixels (image) to the screen. The actual pixel output rate also depends on many other factors, especially the memory bandwidth of the card - the lower the bandwidth is, the lower the ability to reach the max fill rate.
