Compare any two graphics cards:
GeForce GTX 460 vs Radeon HD 5770
IntroThe GeForce GTX 460 makes use of a 40 nm design. nVidia has set the core speed at 675 MHz. The GDDR5 RAM runs at a speed of 900 MHz on this specific card. It features 336 SPUs along with 56 TAUs and 24 ROPs.
Compare those specs to the Radeon HD 5770, which comes with a core clock frequency of 850 MHz and a GDDR5 memory frequency of 1200 MHz. It also uses a 128-bit bus, and makes use of a 40 nm design. It features 800(160x5) SPUs, 40 Texture Address Units, and 16 ROPs.

GeForce GTX 460 wins
(Based entirely on the benchmarks listed above)
When combining all game benchmark scores on this page together, the GeForce GTX 460 wins overall, by 40 FPS. Please note that we do not have the results of every benchmark ever done for these cards, so the results may differ wildly in different games.
Power Usage and Theoretical Benchmarks
Power Consumption (Max TDP)
As far as performance goes, the GeForce GTX 460 should in theory be a little bit better than the Radeon HD 5770 in general. (explain)
Texel RateThe GeForce GTX 460 is a little bit (about 11%) faster with regards to texture filtering than the Radeon HD 5770. (explain)
Pixel RateThe GeForce GTX 460 will be a small bit (more or less 19%) better at FSAA than the Radeon HD 5770, and also able to handle 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 largest amount of data (measured in megabytes per second) that can be moved over the external memory interface in one second. The number is worked out by multiplying the bus width by the speed of its memory. In the case of DDR type RAM, the result should be multiplied by 2 once 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 anti-aliasing, High Dynamic Range and higher screen resolutions.
Texel Rate: Texel rate is the maximum texture map elements (texels) that can be processed per second. This number is worked out by multiplying the total number of texture units by the core clock speed of the chip. The higher this number, the better the graphics card will be at texture filtering (anisotropic filtering - AF). It is measured in millions of texels processed in one second.
Pixel Rate: Pixel rate is the maximum number of pixels the graphics card can possibly record to its local memory in one second - measured in millions of pixels per second. The figure is worked out by multiplying the amount of colour 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, most notably the memory bandwidth of the card - the lower the memory bandwidth is, the lower the potential to get to the max fill rate.
