Compare any two graphics cards:
GeForce 9600 GT 1GB vs Radeon HD 6750
IntroThe GeForce 9600 GT 1GB features a GPU clock speed of 650 MHz, and the 1024 MB of GDDR3 RAM runs at 900 MHz through a 256-bit bus. It also is made up of 64 SPUs, 32 Texture Address Units, and 16 ROPs.
Compare all of that to the Radeon HD 6750, which has GPU core speed of 725 MHz, and 512 MB of GDDR5 RAM set to run at 1000 MHz through a 128-bit bus. It also is comprised of 720 Stream Processors, 36 TAUs, and 16 Raster Operation Units.
Power Usage and Theoretical Benchmarks
Power Consumption (Max TDP)
In theory, the Radeon HD 6750 should perform just a bit faster than the GeForce 9600 GT 1GB in general. (explain)
Texel RateThe Radeon HD 6750 will be much (about 25%) faster with regards to AF than the GeForce 9600 GT 1GB. (explain)
Pixel RateIf running with a high resolution is important to you, then the Radeon HD 6750 is the winner, but 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.
Please note that the price comparisons are based on search keywords - sometimes it might show cards with very similar names that are not exactly the same as the one chosen in the comparison. We do try to filter out the wrong results as best we can, though.
Memory Bandwidth: Bandwidth is the max amount of information (measured in megabytes per second) that can be moved over the external memory interface in one second. It's calculated by multiplying the card's interface width by its memory speed. If the card has DDR memory, it must be multiplied by 2 once again. If it uses DDR5, multiply by 4 instead. The better the memory bandwidth, the faster the card will be in general. It especially helps with anti-aliasing, HDR and higher screen resolutions.
Texel Rate: Texel rate is the maximum number 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 speed of the chip. The better the texel rate, the better the 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 most pixels that the graphics chip could possibly write to its local memory in a second - measured in millions of pixels per second. Pixel rate is worked out by multiplying the amount 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 rate is also dependant on many other factors, especially the memory bandwidth of the card - the lower the bandwidth is, the lower the ability to get to the maximum fill rate.
