CPU performance
Let's see how the Nexus 7 stacks up against a wide range of competitors, including the latest iPads, the Kindle Fire, the Galaxy Tab 10.1, and all of Asus' Transformer tablets. We'll starting with Linpack, which measures raw CPU performance. Unfortunately, the iOS version of Linpack appears to be quite different from the one available on the Android Market, so the Apple tablets are going to sit out this round. Since the variant of Linpack available through the Amazon Appstore doesn't specify whether it's a single- or multithreaded build, the Kindle Fire will also be riding the pine.

The Nexus 7 scores higher than the Transformer Pad 300 in both tests. Since the two tablets use the same Tegra 3 T30L processor, it looks like Jelly Bean offers a nice boost to CPU performance over Ice Cream Sandwich. All the Transformers are running ICS, while the Galaxy Tab is saddled with an older version of Android.

In the multithreaded test, the Nexus cranks out more MFLOPs than even the Transformer Pad Infinity, whose Tegra 3 variant has much higher clock speeds than the T30L. Seems like Jelly Bean is not only faster for single-threaded loads, but also more adept at exploiting multi-core processors.

I wouldn't make too much of the Transformer Prime's high scores in the multithreaded test. We tested that tablet back in February with an older version of Ice Cream Sandwich. The Prime has since gone back to Asus, so we haven't had the opportunity to retest it with a newer build of the OS.

Tablets are probably used for web surfing more than anything else, so we'll move onto a couple of browser-based tests. First up is the SunSpider JavaScript benchmark. As you might've guessed, this test probes JavaScript execution speeds.

Impressive. The Nexus 7 steals the top spot from the iPads, putting the Google tablet well ahead of its closest Android rival.

FutureMark's Peacekeeper benchmark also tests JavaScript performance, this time with a side order of HTML5.

Google's lead over the competition is even larger in Peacekeeper, where the Nexus 7 beats the second-place iPad 3 by nearly 100 points.

As it turns out, the Nexus 7's strong web-browsing performance has more to do with Chrome than anything else. We ran SunSpider and Peacekeeper on the Transformer Pad Infinity using Chrome, and the tablet scored higher than the Nexus 7 in both benchmarks. It's also worth noting that Chrome completes two of Peacekeeper's seven HTML5 tests, while the default browsers on the other tablets can run just one of those tests.
