Apple's A5X allegedly has four times the performance of Nvidia's Tegra 3 chip, but without benchmarks and footnotes, the claims ring hollow.
Nice chart, but some benchmarks and footnotes would be nice.
Apple took direct aim at Nvidia's Tegra 3 — a processor for a new batch of superphones — when it launched its latest iPad this week. The problem: Apple had a chart showing that it has four times the performance of Tegra 3, but provided no benchmarks or footnotes.
Anyone accustomed to the Intel-AMD benchmark wars knows that any chart has more footnotes than a commercial for antidepressants. That's why Apple's chart looked off. Nvidia was digesting Apple's iPad claims just like everyone else via live blogs.
Ken Brown, a spokesman for Nvidia, said that it was "certainly flattering" to be called out by Apple, but the performance claims are sketchy without more data. "We don't have the benchmark information," said Brown. "We have to understand what the application was that was used. Was it one, or a variety of applications? What drivers were used? There are so many issues to get into with benchmark."
Will Apple provide those benchmarks? It's doubtful. However, Nvidia plans to get a new iPad when they go on sale on 16 March, and do some comparisons tablet to tablet. "At some point, it will become more clear what the performance really is," said Brown. "For now, Apple has a really generic statement."
