Nvidia GeForce GTX 1070 4K benchmarks leak for notebooks
Laptopmedia.com or its sources may have allegedly broken an Nvidia NDA by obtaining early pre-production notebooks with the powerful GTX 1070 GPU and publishing its gaming results for the public to see. If the numbers are proven to be true, then the gaming potential of the GTX 1070 in 1080p or 2160p looks very promising for notebooks. Laptopmedia has taken down the page as of this writing citing an August 16th publishing date, which further adds credibility to its scores.
In short, the source concludes that the GTX 1070 Notebook is sufficient for even 4K UHD gaming up to High detail settings and its results are close to - if not slightly slower - than our benchmarks with the desktop GTX 1070. The results also show a healthy lead over the current GTX 980M and even the GTX 980 Notebook.
Based on the data, we can expect the notebook GTX 1070 to be about 5 to 20 percent slower than the desktop GTX 1070 depending on the game and application. We can then assume that the notebook GTX 1080 would be about 5 to 25 percent slower than the desktop GTX 1080. Meanwhile, the GTX 980M can be up to 30 to 40 percent slower than the GTX 1070 if these benchmarks are correct. It's looking very optimistic that the mobile Pascal series will make the jump to 4K that much easier for gaming notebooks as it has done for desktop users.
