We all know that Tegra4 has powerful performance, and NVIDIA Shield also uses this new SoC, and the score of this most powerful handheld is also revealed on GFXBench's website.
From GFXBench 2.7, the Shield is one frame higher than the current strongest I9505.
On GFXBench 2.5, NVIDIA Shield is only 0.1 frame higher than the second place iPad 4, but the plug-in can be closed until the test date is April 12, so Shield is likely to abandon the iPad 4 through optimization.
NVIDIA Shield Score Summary.
NVIDIA Shield uses a 720P screen, and the CPU frequency ranges from 51MHz to 1.9GHz.
