According to a report by AnandTech, Apple’s new A5 System on a Chip (SoC) includes a more powerful PowerVR SGX 543MP2 instead of the PowerVR SGX 535 used in the original A4.
Architecturally the 543MP2 has more than twice the compute horsepower of the SGX 535 used in Apple’s A4. Each shader pipeline can execute twice the number of instructions per clock as the SGX 535, and then there are four times as many pipes in an SGX 543MP2 as there are in a 535. There are also efficiency improvements as well. Hidden surface removal works at twice the rate in the 543MP2 as it did in the 535. There’s also a big boost in texture filtering performance.
AnandTech conducted GLBenchmark 2.0 tests to find out the triangle throughput tests and observed that iPad 2 delivered results 3 to 5 times faster than iPad 1 and 2 to nearly 7 times faster than Motorola Xoom.
AnandTech also found that iPad 2 ran at 5.4 times the framerate of iPad 1, which grows to 7 times if anti-aliasing is turned on and 3.7 times the framerate of the Xoom.
The Pro tests showed a 3 to 5 times performance improvement compared to iPad 1.
To understand what it means from a user point of view, checkout the in-game screenshots of Infinity Blade iPad game by Epic Games optimized for iPad 2. You can see the improvement in graphics quality on iPad 2 compared to iPad 1:
If there were any doubts, the results clearly show that Apple’s new A5 chip blows away Nvidia’s Tegra 2 chip that powers Motorola Xoom, which will also be used in a number of tablets that will be released this year such as Dell Streak 7, G-Slate, Acer ICONIA Tab A500, Asus Eee Pad Transformer, Asus Eee Pad Slider.
We expect the new A5 chip with the more powerful PowerVR SGX 543MP2 to used in the next generation iPhone – iPhone 5.
Are you still thinking of buying a Tegra 2 powered tablet instead of iPad 2?
