Pro Best GTX 1070 performance
The sample card has scored an impressive 99.3% consistency in its performance in the 3DMark stress test. In the Fire Strike Full HD benchmark by 3DMark, the GTX 1070 GameRock Premium Edition scores 16,275 points - a 7.75% increase of the GTX 1070 Founder's Edition's 15,099 points. Reviewers at Hexus even measured 2,025MHz core boost speeds (higher than the guaranteed 1,873MHz), so that's some pretty impressive consistent performance for a GTX 1070 card. Comparing it to other 1070 cards, it comes out on top for both memory clock speeds as well as GPU clock speeds.
In terms of differences in games, the GameRock edition of the GTX 1070 is often able to achieve slightly higher framerates when compared to a reference GTX 1070. In Fallout 4 for example, this GPU manages to score an average FPS of 125 in Full HD, while a regularly clocked GTX 1070 only reaches 118 FPS.
A similar difference can be seen in 1440p resolution, with 85 fps on the Palit vs 78 fps on the reference card. In Hitman at 1080p, the Palit GameRock manages to achieve an average framerate of 106 fps versus 98 for the Founders Edition. In 1440p, the GameRock Premium Edition boosts the average fps from 74 to 80. In Rise of the Tomb Raider, the performance difference is more noticeable. The Palit GameRock can handle an average framerate of 135 in Full HD, which is ten frames per second higher than the GTX 1070 FE. Similarly, this card improves upon the reference card by 9 fps for a total of 90 FPS in 1440p.
Pro Great cooling solution
Palit's GTX 1070 cards have large fans and use their trademarked JetStream technique to offer effective cooling which allows for plenty of cooling, even when overclocking. It's uncommon for graphic card manufacturers to use two separate heatsinks like Palit does here on their GTX 1070 - one for the GPU & RAM and one for the VRM's - but it works very well.
Compared to the reference GTX 1070 Founders Edition, the Palit GameRock stays cooler even with the highly increased clock speeds. In idle, the GTX 1070 GameRock Premium Edition heats up to 44 degrees Celsius, which is a tad higher than the Founders Edition's 39°. Under full load however, Palit's cooler can show its worth with a maximum temperature of only 70 degrees Celsius, compared to the Founders Edition's 82 degrees. The cooler by Palit prevents throttling (the graphics card will slow itself down in order to stay cool: this generally happens around the 80° C mark).
Pro Quietest operation of any GTX 1070 card
The GTX 1070 GameRock's cooler not only handles heat well, but noise production is very low, especially compared to other high-end cards. With a decibel rating of 29.6 in idle, the card remains essentially silent - this is because the fans don't spin up until a temperature of 50° C has been reached. During full load, the fans can barely be heard with a noise production of 32.4 decibels. With these results, the Palit GeForce GTX 1070 GameRock is among the best in terms of sound production. For comparison: the Founders Edition produces 30.4 and 35.3 decibels in idle and under full load, respectively.
Pro Very high clock speed increases
The Premium Edition of the Palit Geforce 1070 GameRock has a 1,671 MHz clock speed with a guaranteed boost speed of 1,873 MHz. That is a clear difference to the 1,506 MHz / 1,683 MHz of the Founders Edition. Palit also increased effective memory speeds from 8k MHz to 8.5k MHz (2x 4,250 MHz) . This manufacturer's main selling point is the performance they get out of NVIDIA cards and in this case as well they pushed the GTX 1070 to the limits of its design.
Pro Great energy to performance ratio
The increased performance pushes this card from the standard 150W for GTX 1070's to 170W for this version. However, that is still more energy efficient than EVGA's most powerful GTX1070 (215W), which doesn't produce as much base & memory clock speeds.
Con Only available in Europe
Palit graphic cards are only sold in Europe. In the USA, some of these graphics cards are sold by PNY but unfortunately, the GTX 1070 Gamerock Premium Edition is not one of those.
Con Takes up a lot of space
Because of the big fans and large backplate on this card, the Palit Geforce GTX 1070 GameRock Premium Edition takes up two and a half slots. (Or in other words, effectively needs 3 available slots.)
