See a comparison between A5X (from Apple) and Tegra 3 (from NVIDIA) processors

During the presentation of the new iPad, Apple challenged NVIDIA, stating that its A5X processor (with graphics quad-core) four times faster than Tegra 3, a chip that equips some competitive tablets, such as ASUS?s Transformer Prime.

NVIDIA did not like this and said that as soon as Ma's gadget hit the market, they would run some tests to see if the information matches. However, the LAPTOP Magazine anticipated and already performed some tests, comparing the new iPad tablet from ASUS mentioned above.

Using GLBenchmark 2.1, a tool for benchmark available on both platforms (iOS and Android), the Apple tablet performed better. In the test performed in which 3D animations were shown, the A5X processed 6,718 frames at a rate of 60 frames per second, while the numbers for Tegra 3 were 5,939 and 53, respectively.

In the geometric test (weighted vertex), the new iPad also did well, processing 7,530,524 frames at a rate of 57fps, while the Tegra 3 processed 3,523,926 at 27fps. In the fill test, which measures the speed of texturing, the iPad was better again: 1.9 billion per second against 404.6 million from the Transformer Prime.

The story changes when the Geekbench benchmark multiplatform that measures processing power instead of graphics comes into play. Tegra 3 (quad-core) did well and scored 1,571 points against 692 of the A5X (dual-core). In whole numbers: 1,391 for Tegra 3 and 614 for A5X; floating points: 2,408 vs. 825; memory subtest: 1,076 vs. 784; subtest stream 266 for the Tegra 3 and 324 for the A5X. That is, when we leave the graphical item and analyze the processing, the Tegra 3 performs better than the Apple chip.

Navigation was also one of the factors tested in two different benchmarks. The Peacekeeper test showed a very close score, with the iPad reaching 386 points and the Transformer Prime 387. In the SunSpider test (JavaScript rendering), the iPad was better: 1.8 milliseconds against 2.2 milliseconds of the tablet ASUS remembering that browsers are different, which can influence the result.

They also tested games, taking the same game available on both platforms and running next to each other. Here the test is very subjective, precisely because of the methodology used.

While the new iPad showed more colorful and clear graphics, the Transformer Prime featured some visual elements not found on the Apple tablet. The problem is that, on the side of the new iPad, the perceived differences are more ?the fault? of the Retina display than of the processor itself. On the Transformer Prime side, developers may have added features for the Android version that don't (yet?) Exist on the iOS version. In short: as I said, the test is very subjective and we cannot say that such quality is inherent to the processor or something like that.

Overall, the A5X won in some tests, and the Tegra 3 in others. It remains to be seen exactly which was used by Apple probably the GLBenchmark 2.1 or a similar one, which resulted in a performance four times higher.
