The reference board for the new Exynos 5420 processor from Samsung got pitted against the Nexus 10 with 5250, and as can be expected, it destroyed the older processor edition. It not only has beefier processor cores, but also a six-core Mali T-628 GPU, so the 3D rendering results were night and day. We can't wait to hear which will be the first device Samsung will place this bad boy into, as mass production starts next month. There is apparently a new Nexus 10 on the way, so that's where the powerful silicon might end...
