Compare any two graphics cards:
Geforce GTX 680 vs Radeon HD 7870
IntroThe Geforce GTX 680 comes with a GPU core speed of 1006 MHz, and the 2048 MB of GDDR5 memory is set to run at 1502 MHz through a 256-bit bus. It also is comprised of 1536 Stream Processors, 128 Texture Address Units, and 32 Raster Operation Units.Compare those specs to the Radeon HD 7870, which comes with a core clock speed of 1000 MHz and a GDDR5 memory frequency of 1200 MHz. It also features a 256-bit memory bus, and makes use of a 28 nm design. It features 1280 SPUs, 80 Texture Address Units, and 32 Raster Operation Units.

Power Usage and Theoretical BenchmarksPower Consumption (Max TDP)
Memory BandwidthAs far as performance goes, the Geforce GTX 680 should theoretically be a lot better than the Radeon HD 7870 overall. (explain)
Texel RateThe Geforce GTX 680 will be quite a bit (about 61%) more effective at anisotropic filtering than the Radeon HD 7870. (explain)
Pixel RateThe Geforce GTX 680 will be just a bit (approximately 1%) better at anti-aliasing than the Radeon HD 7870, and also should be able to handle higher 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. Price Comparison

Display Specifications
Memory Bandwidth: Bandwidth is the largest amount of information (counted in MB per second) that can be transferred across the external memory interface in one second. The number is worked out by multiplying the interface width by the speed of its memory. If it uses DDR RAM, it must be multiplied by 2 once again. If it uses DDR5, multiply by 4 instead. The higher the bandwidth is, the faster the card will be in general. It especially helps with AA, HDR and high resolutions. Texel Rate: Texel rate is the maximum texture map elements (texels) that are processed in one second. This number is calculated by multiplying the total number of texture units of the card by the core 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 applied per second. Pixel Rate: Pixel rate is the maximum amount of pixels the video card could possibly write to the local memory in one second - measured in millions of pixels per second. Pixel rate is worked out by multiplying the amount of colour ROPs by the clock speed of the card. ROPs (Raster Operations Pipelines - sometimes also referred to as Render Output Units) are responsible for filling the screen with pixels (the image). The actual pixel output rate is also dependant on quite a few other factors, most notably the memory bandwidth of the card - the lower the memory bandwidth is, the lower the ability to get to the max fill rate.

4 Responses to “Geforce GTX 680 vs Radeon HD 7870”The 680 is definitely the way to go! Yet its suprisingly cheaper too. Hence why its already sold out and nowhere to be found... Still not that much different in price from the GTX 580. And the 7970 right now is still more expensive. 680 FTW!! 😀
waho niente male sul pixel addiritura allora la 7970 e piu potente della 7950 ho cosa...
Thanks to its 1000MHz clock speed, the Radeon HD 7870 has higher pixel fill and rasterization rates than even the Radeon HD 7970. That's because the two cards have the same number of ROPs, and they can both process two triangles per clock, but the 7970 is only clocked at 925MHz. The 7870 does have more modest texture filtering capabilities, though, not to mention substantially lower shader throughput and memory bandwidth. Source : http://techreport.com/articles.x/22573/2
The 7870 has better price performance
7870 = I found an OC'd version for 178.98 euros on PIXmania (sapphire 2gb)
680 = Is 300 euros on it's cheapest and overclocking is harder and less effective on a 680
