Summary: ZOTAC's GeForce GTX 680 AMP! Edition comes with one of the largest out of the box overclocks on the whole market. Its base clock is 100 MHz higher than the reference design, when conditions allow, it will boost up to 1202 MHz. In our testing this results in a 7% performance increase when averaged over our benchmark suite.
Pros: Large performance increase, Massive overclock out of the box, Assassin's Creed triple game bundle, Up to four active displays now, makes surround possible with one card, Low noise in 3D, Support for PCI-Express 3.0 and DirectX 11.1, Support for CUDA and PhysX
Cons: High price, Limited additional overclocking potential, Dynamic OC can't be turned off, Manual overclocking more complicated than before, Idle fan noise not reduced, Triple slot design not for all, Heatpipes sticking out of the cooler might not fit all cases, No technology similar to AMD's ZeroCore power
Summary: The Zotac GeForce GTX 680 is a high-end graphics card based on nVidia's Kepler chip. Our GeForce GTX 680 review shows that the Zotac nVidia GTX 680 is faster and less power hungry than some more expensive rivals.
Conclusion: The GTX 680 has shown itself to be an awesome performer and a great overclocker too, once you understand the dynamic overclocking. The card ripped through every game test and did excellent in the benchmarks too. It does start to make some noise when running tests made to work your card to the max but in gaming you’ll likely rarely hear the card unless you’re really into quiet computing. The supplied bundle was small but what was included was good.
Pros: Great performance, Flashy looks, Very Quiet, Runs cool, Dynamic overclocking keeps clocks high
Cons: Dynamic overclocking can be annoying if you’re trying to manual overclock, High price
Summary: Entrambe le schede video testate hanno dimostrato prestazioni eccellenti, ma la vera sorpresa è stata la GeForce GTX 670 AMP! Edition che, nella maggior parte dei test, è risultata più veloce anche della GeForce GTX 680 reference.
Il “depotenziamento” della GPU GK-104 da 1536 a 1344 CUDA Cores è infatti ampiamente compensato dalla frequenza operativa maggiore, che si riflette inoltre in un utilizzo più aggressivo della tecnologia GPU Boost.
