This fellow just benchmarked a new tablet runing the next generation Atom SOC called Bay Trail:
I got to spend some time with 2 tablet prototypes last week.
z3770 at 2.3 ghz max, 1.46 ghz, Win 8.1 pre Kraken 1.1 score: 7631
Snapdragon 800 2.15 ghz max, Win 8.1 RT pre Kraken 1.1 score: 12526
I couldn’t install anything on these machines so Kraken was what I could run in the time available. Both scores in IE obviously, both machines had 2GB Ram, shouldn’t matter for Kraken. Both got warm but neither was uncomfortably hot. z3770 was completely unlocked unlike previous engineering samples I’ve seen. The Snapdragon was very quick and responsive unlike previous RT devices but the Baytrail was simply awesome for an Atom processor, subjectively felt more like an Ivy Bridge Core processor than an Atom processor. Try running Kraken on your Core processor and you will see how much of a game changer a 7631 kraken score is out of a tablet. I know Kraken’s limitations quite well but this result was somewhat consistent with some other leaked results so I’m not completely surprised.
Out of curiosity, I downloaded Kraken (from Mozilla) and ran the same benchmarks. Here are the results:
RESULTS (means and 95% confidence intervals)
Total: 14704.1ms +/- 2.4%
ai: 1790.3ms +/- 10.0%
astar: 1790.3ms +/- 10.0%
stanford: 3983.8ms +/- 4.3%
crypto-aes: 1304.8ms +/- 6.6%
crypto-ccm: 704.3ms +/- 17.3%
crypto-pbkdf2: 1494.4ms +/- 7.1%
crypto-sha256-iterative: 480.3ms +/- 6.4%
With Kraken, the lower the number, the better. So apparently a tablet running Bay Trail should be approximately twice as fast and powerful as the one I’m using now runing Clover Trail.
In other words, these new Atom SOCs are in the same ballpark as third generation Core chips, but much less expensive and power hungry.
Bottom line: If you’re thinking about a new tablet, wait until the models running Bay Trail start to roll out in a few weeks. You’ll pay less, and get more than anything you can pick up today.
