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

Power Usage and Theoretical Benchmarks
Power Consumption (Max TDP)
The GeForce 8600 GTS, in theory, should be a little bit faster than the Radeon HD 5570 in general. (explain)
Texel RateThe Radeon HD 5570 will be a little bit (approximately 20%) better at AF than the GeForce 8600 GTS. (explain)
Pixel RateThe GeForce 8600 GTS is a bit (approximately 4%) more effective at full screen anti-aliasing than the Radeon HD 5570, and should be capable of handling higher screen resolutions better. (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 information (measured in MB per second) that can be transferred over the external memory interface within a second. It's worked out by multiplying the bus width by its memory speed. If it uses DDR memory, it should be multiplied by 2 once again. If it uses DDR5, multiply by 4 instead. The higher the memory bandwidth, the better the card will be in general. It especially helps with AA, High Dynamic Range and high resolutions.
Texel Rate: Texel rate is the maximum texture map elements (texels) that can be applied per second. This figure is worked out by multiplying the total texture units by the core clock speed of the chip. The better this number, the better the graphics card will be at handling 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 that the graphics chip could possibly record to the local memory in one second - measured in millions of pixels per second. Pixel rate is calculated by multiplying the amount of Raster Operations Pipelines by the the core 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 fill rate is also dependant on lots of other factors, especially the memory bandwidth of the card - the lower the bandwidth is, the lower the potential to reach the max fill rate.
