Compare any two graphics cards:
GeForce 9600 GT 1GB vs Radeon HD 5770
IntroThe GeForce 9600 GT 1GB makes use of a 65/55 nm design. nVidia has clocked the core speed at 650 MHz. The GDDR3 RAM runs at a speed of 900 MHz on this model. It features 64 SPUs along with 32 Texture Address Units and 16 ROPs.
Compare those specs to the Radeon HD 5770, which uses a 40 nm design. AMD has clocked the core speed at 850 MHz. The GDDR5 RAM is set to run at a frequency of 1200 MHz on this card. It features 800(160x5) SPUs as well as 40 TAUs and 16 ROPs.
Power Usage and Theoretical Benchmarks
Power Consumption (Max TDP)
The Radeon HD 5770 should in theory perform a lot faster than the GeForce 9600 GT 1GB in general. (explain)
Texel RateThe Radeon HD 5770 should be much (more or less 63%) more effective at texture filtering than the GeForce 9600 GT 1GB. (explain)
Pixel RateThe Radeon HD 5770 should be much (more or less 31%) faster with regards to anti-aliasing than the GeForce 9600 GT 1GB, and 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.
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: Memory bandwidth is the max amount of information (measured in megabytes per second) that can be transferred across the external memory interface in one second. The number is calculated by multiplying the interface width by its memory clock speed. If the card has DDR type RAM, it must be multiplied by 2 again. If it uses DDR5, multiply by 4 instead. The better the card's memory bandwidth, the faster the card will be in general. It especially helps with AA, High Dynamic Range and higher screen resolutions.
Texel Rate: Texel rate is the maximum number of texture map elements (texels) that are processed in one second. This figure is calculated by multiplying the total texture units by the core speed of the chip. The better the texel rate, the better the card will be at texture filtering (anisotropic filtering - AF). It is measured in millions of texels in one second.
Pixel Rate: Pixel rate is the maximum amount of pixels that the graphics chip can possibly write to its local memory in a second - measured in millions of pixels per second. The number is calculated by multiplying the amount of Render Output Units by the clock speed of the card. ROPs (Raster Operations Pipelines - aka Render Output Units) are responsible for filling the screen with pixels (the image). 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 reach the maximum fill rate.
