Compare any two graphics cards:
Geforce GTX 680 vs Radeon HD 7770
IntroThe Geforce GTX 680 has core clock speeds of 1006 MHz on the GPU, and 1502 MHz on the 2048 MB of GDDR5 memory. It features 1536 SPUs along with 128 TAUs and 32 ROPs.Compare those specifications to the Radeon HD 7770, which has clock speeds of 1000 MHz on the GPU, and 1125 MHz on the 1024 MB of GDDR5 RAM. It features 640 SPUs along with 40 TAUs and 16 ROPs.

Power Usage and Theoretical BenchmarksPower Consumption (Max TDP)
Memory BandwidthTheoretically speaking, the Geforce GTX 680 should be a lot faster than the Radeon HD 7770 overall. (explain)
Texel RateThe Geforce GTX 680 is much (approximately 222%) better at texture filtering than the Radeon HD 7770. (explain)
Pixel RateIf running with lots of anti-aliasing is important to you, then the Geforce GTX 680 is superior to the Radeon HD 7770, 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. Price Comparison

Display Specifications
Memory Bandwidth: Bandwidth is the largest amount of information (measured in megabytes per second) that can be transferred over the external memory interface in one second. The number is calculated by multiplying the interface width by the speed of its memory. If the card has DDR type RAM, it must be multiplied by 2 once again. If it uses DDR5, multiply by ANOTHER 2x. The better the bandwidth is, 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 number of texture map elements (texels) that are processed in one second. This is worked out by multiplying the total texture units of the card by the core clock 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 processed in one second. Pixel Rate: Pixel rate is the maximum number of pixels that the graphics chip could possibly record 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 - also sometimes called Render Output Units) are responsible for filling the screen with pixels (the image). The actual pixel output 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 get to the maximum fill rate.

4 Responses to “Geforce GTX 680 vs Radeon HD 7770”confusion ? which would be the next buy AMD or NVIDIA both companies has launched there Gen 3 based cards can u suggest good 3d support budget card . around 250$ .
GTX 560TI [448 cores] if u care Nvidia's PhysiX simulation or Radeon HD7850 if u care better graphics [probably better filtering technology]

these results are very surprising i thought the 7770 would have been more of a challenge. i own a sapphire hd 7770 ghz oc... perhaps this card should be compared to the gtx 680 instead of the stock 7770
