Compare any two graphics cards:
GeForce GTX 285 1GB vs Radeon HD 6850
IntroThe GeForce GTX 285 1GB features a GPU core speed of 648 MHz, and the 1024 MB of GDDR3 RAM runs at 1242 MHz through a 512-bit bus. It also features 240 Stream Processors, 80 Texture Address Units, and 32 ROPs.
Compare all of that to the Radeon HD 6850, which makes use of a 40 nm design. ATi has clocked the core frequency at 775 MHz. The GDDR5 RAM runs at a frequency of 1000 MHz on this particular model. It features 960 SPUs along with 48 TAUs and 32 ROPs.

Power Usage and Theoretical Benchmarks
Power Consumption (Max TDP)
As far as performance goes, the GeForce GTX 285 1GB should in theory be quite a bit better than the Radeon HD 6850 in general. (explain)
Texel RateThe GeForce GTX 285 1GB is quite a bit (more or less 39%) faster with regards to anisotropic filtering than the Radeon HD 6850. (explain)
Pixel RateIf using a high resolution is important to you, then the Radeon HD 6850 is a better choice, but only just. (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: Memory bandwidth is the largest amount of data (measured in megabytes per second) that can be transferred over the external memory interface in a second. It's worked out by multiplying the card's bus width by its memory clock speed. If the card has DDR memory, the result should be multiplied by 2 once again. If DDR5, multiply by 4 instead. The higher the bandwidth is, the better the card will be in general. It especially helps with anti-aliasing, HDR and high resolutions.
Texel Rate: Texel rate is the maximum amount of texture map elements (texels) that can be processed per second. This figure is calculated by multiplying the total texture units by the core speed of the chip. The higher this number, the better the card will be at texture filtering (anisotropic filtering - AF). It is measured in millions of texels applied per second.
Pixel Rate: Pixel rate is the maximum number of pixels the graphics card could possibly record to its local memory in a second - measured in millions of pixels per second. The number is calculated by multiplying the number of colour ROPs by the the core clock speed. ROPs (Raster Operations Pipelines - also sometimes called Render Output Units) are responsible for drawing the pixels (image) on the screen. The actual pixel output rate also depends on quite a few other factors, most notably the memory bandwidth - the lower the bandwidth is, the lower the potential to get to the max fill rate.
