The Bay Trail Preview: Intel Atom Z3770 Testedby Anand Lal Shimpi & Brian Klug on September 11, 2013 12:00 PM EST
In addition to showing Bay Trail running on a Windows 8.x platform, Intel showed us a “pre-beta” version of the platform running Android 4.2.2. I have to emphasize that the build they showed us definitely seemed pre-beta, as there was some instability, but overall the build was good enough to run some tests on and get a feel for. Intel made it clear that they do have a lot more work to do on their Android build before it’s considered close to final quality than the Windows equivalent.
Inside Android we can still see the CPU state table data and how long the cores are sitting in each performance state still, despite this now being managed in-silicon on Bay Trail. In addition Android sees the 2.39 GHz Z3770 boost frequency and reports it. I didn’t see any strange behavior on the device while running tests and watching CPU frequency, if anything the reference design platform stayed at the maximum boost frequency even with four cores plugged in for an impressive amount of time. Of course this is a tablet so there’s more TDP to play around with compared to a phone.
Depending on where you were in the Android UI, there was some definite stutter, but I’m told this is a result of an issue with Dalvik not allocating threads to cores properly that Intel is still tuning, something which you can see plays itself out as well in the AndEBench Java test that runs in Dalvik. The launcher especially had some stutter, but Intel claimed they were aware of it and that final performance in areas like that would be dramatically improved. Regardless of the state of Bay Trail’s Android port, it affords us the opportunity to look at performance through our pretty standard benchmark suite.
Google Octane is another JS test that isn’t quite as platform optimized yet, here there’s once again dominance by Bay Trail with just over a 50 percent higher score.
AndEBench is a combination native compiled microkernel benchmark (indicative of NDK application performance) that also runs a very similar workload atop Dalvik like a normal Android Java application. Here we can see what Intel was talking about when they said they have more work to do getting Dalvik working properly at dispatching threads to appropriate cores, hopefully the Java number will climb considerably. The native test also shows a lead over the competition.
While Bay Trail clearly leads on the CPU side, its GPU performance is more middle of the road - at least among the higher end SoCs. In 3DMark Bay Trail's GPU performance is aided by the more CPU bound nature of the benchmark, but here Intel is able to beat the Snapdragon 600. Snapdragon 800 on the other hand pulls ahead by around 35%.
The 3DMark Physics test is effectively a CPU test, which once again plays to Bay Trail's strengths. Here it's faster than Snapdragon 800 and Cortex A15. Only Ivy Bridge is quicker in a tablet.
Basemark X is a bit more GPU bound than 3DMark, and we also have iOS data here so we can put Bay Trail's performance in better perspective. Here Bay Trail is a bit slower than the iPad 4, and clearly Tegra 4 and Snapdragon 800. Intel's GPU in Android is measurably quicker than Adreno 320/S600 though.
Bay Trail's onscreen performance is penalized by the FFRD's extremely high native resolution.
The more interested GLBenchmark numbers, T-Rex HD, show Bay Trail just behind the iPad 4 in performance. It's definitely not bad at all but clearly not industry leading.

CharonPDX - Wednesday, September 11, 2013 - linkI'm just curious why, in every single Intel-provided slide, they use the name "Bay Trail" as two words, why you use "Baytrail" as a single word? There is no ambiguity, they mean Bay Trail as two words.
DominionSeraph - Wednesday, September 11, 2013 - linkYou should email corrections in grammar/spelling to the author. When you put them in the comments it gets orphaned after they make the fix. They don't clean up the comments to correspond to the cleanup of the article.

Or he could just get over it and not make an issue of it since its totally unimportant ;)
rondriggs - Friday, September 13, 2013 - linkOne new series of Android tablets to launch this week are powered by Intel's new Z2580 Clover Trail processor - which offers impressive performance for mid-range devices.
Ramos Technology is one of the better-known China based tablet manufacturers and has teamed-up with Intel to introduce the I-Series with 8", 9" and 10" Android models (starting at $199).... with very competitive pricing and solid features, including high resolution displays.
Intel's new processor with Hyper-Threading technology runs four threads simultaneously and scores extremely well in benchmark testing, compared to other mainstream Quad-core tablets.
The i9 is the first of the series available this week and offers an 8.9-Inch model - which features a 1900x1200 display with Samsung advanced PLS technology.
One of the first sources in the U.S. to feature the new Ramos I-Series, and for complete details -- go to-- Tab l e t S p r i n t
WarrenSmith - Saturday, September 14, 2013 - linkLove my job, since I've been bringing in $5600… I sit at home, music playing while I work in front of my new iMac that I got now that I'm making it online( Click on menu Home)
speculatrix - Monday, September 30, 2013 - linkwhy still no "report as spam" button?
Megacharge - Thursday, October 24, 2013 - linkThat's all you bring in is $5600?? Wow dude, you need to stop sitting at home, playing music, and spending money you don't have on over priced Apple computers, and get out there and find a real job bro...
Paladin238 - Wednesday, September 11, 2013 - linkEMMC...*sigh* really, that was the only problem I had with Clover Trail tabs was the eMMC was terrible lay slow at anything. I thought they were adding SATA 2 support. Wouldn't running a external USB 3 drive be faster? Lol
axien86 - Wednesday, September 11, 2013 - linkSeveral reviewers mentioned that loading some popular games took forever to load thanks to the hobbled EMMC I/O.
Half-baked I/O performance may be okay for low cost tablets, but many OEMS like Samsung and HP priced their Atoms in $700 plus products.
Paladin238 - Wednesday, September 11, 2013 - linkYeah, I bought the Samsung 500t but the it kept freezing and the installs of anything was brutal.
