Summary: Today we will talk about the design and functionality of the proprietary GeForce GTX 680 graphics cards. We will test two graphics cards like that in an SLI configuration, compare it against a dual-processor GeForce GTX 690 and other products.
Summary: Palit's GeForce GTX 680 JetStream uses a custom triple fan cooler and a custom PCB design. It looks like both have been optimized for cost reduction, which enables the company to offer the card at the same price as the reference design.
Thanks to an overclock of 80 MHz out of the box, we see an about 5% performance increase over the NVIDIA reference design. Usually higher clocks mean higher power consumption, not so with the Palit GTX 680 JetStream.
Pros: No price increase over reference design, Large performance increase, Overclocked out of the box, Additional OC headroom left, Low power consumption, Up to four active displays now, makes surround possible with one card, Quiet, Support for PCI-Express 3.0 and DirectX 11.1, Support for CUDA and PhysX
Cons: Dynamic OC can't be turned off, Manual overclocking more complicated than before, 2 1/2 slot design not for all, No technology similar to AMD's ZeroCore power
Excerpt: 2GB of GDDR5 always seemed like a weird amount of memory to have on the latest NVIDIA video card, the GTX 680. It's not that 2GB isn't a lot, it's just that we're at the point where we feel when spending in excess of $500, we'd have a video card that carried a minimum of 3GB.
Excerpt: It's been ages since we've seen anything from Palit and really it's for good reason. Let's be honest, up until now, it's been a quiet succession of months for NVIDIA when it comes to the video card market and that means for NVIDIA GPU only partners, it's been very quiet for them.
Conclusion: - Zaključak - Mora se priznati kako je Nvidija odradila odličan posao i kako je ovo njihova prva stvarno izvrsna high-end kartica u nekoliko godina. Najviše oduševljava u odnosu potrošnja/performanse gdje dosta nadmašuje HD7970 karticu. U prosjeku za oko 15W manje troši, a za oko 10-15% je brža. GPGPU performanse su kao što smo vidjeli odlične, a tek su OpenGL performanse nešto slabije. Trenutni problem GTX680 kartica je dobavljivost.
Pros: Performanse, solidan OC potencijal, teselacijske i GPGPU performanse, potrošnja, PCIe 3.0, tih rashladni sistem.
Cons: Bundle, slabije OC performanse, uvjetno rečeno visoka cijena.
