Palit's custom GTX 680 gets reviewed
Impressive results from custom card
Hard-working TweakTowner Shane Baxtor got a chance to check out the first custom Geforce GTX 680 that we have seen around on review pages, and we must say that we are quite impressed. JetStream Geforce GTX 680, as Palit decided to name it, features triple-fan design, 8+6-pin PCI-E power connectors and a decent factory overclock.
Unfortunately, there are no pictures of the PCB but Tweaktown noted that the card uses an upgraded 6-phase VRM, rather than the 4-phase one on the reference card so we guess that we are looking at a custom PCB. The Palit JetStream is also factory overclocked and set to work at 1085MHz (from 1006MHz) for base and 1150MHZ (from 1058MHz) for boost clock. The 2GB of GDDR5 memory got overclocked from 6008MHz to 6300MHz.
As noted, the card uses triple-fan configuration with a massive heatsink. The two fans on the sides are 80mm while the middle one is apparently a 90mm special TurboFan that has a different blade design and blue LED lighting. Palit claims that this one should have 10 percent more overclocking performance, be 8 degrees Celsius cooler and 9dB quieter.
The new JetStream GTX 680 is, as expected, quite faster than the reference clocked one. Surprisingly, it does it with lower temperatures, lower power consumption and lower noise so JetStream cooler and 6-phase VRM are certainly doing their job.
According to Tweaktown, the Palit JetStream GTX 680 should be US $20 to US $30 more expensive than the reference one, which interestingly enough still leaves it cheaper than Radeon HD 7970.
