Anton Shilov, the headline is incorrect. The new GPU isn't "almost 200% faster" – it's almost 100% faster.
200% faster would mean 3x the baseline, but Arm said it was almost twice as fast, not three times as fast. Big difference.
Also the claim "4.7 times faster" is confusing. It's not clear what it means, since we usually say "N times as fast", not "N times faster". Arm meant 4.7x, so it's 4.7 times as fast as the baseline. As a percentage, that means 370% faster.
