it says that in a furmark+prime95 the CPU goes to 1.3ghz? if that true Intel changed now Turbo boost works, because CPU turbo had the priority on such cases in the past.

Interesting delta is around 8W for the tablet, though again, this is before the power adapter. Nice to see such high clock can be maintained under a furmark + prime load. Means that any consumer application can run without throttle.

Im kind of expecting the CPU to be able to run at non-turbo clocks 24/7 if there is not temperatures issues.

But i know for a fact that Sandy Bridge and Ivy Bridge ULV processors when nailed to the TDP wall with CPU+IGP 100% load at the same time, it lowers the IGP turbo first, BT seems to be lowering CPU turbo instead of IGP, well there is not reading of IGP clock, but it seems that case.

Just imagine what the Q704 will cost. Agreed Bay Trail at that price is just excessive (I have a Dell Venue 8 Pro cost me $322 after-tax), its a great piece of kit, but at least switch Bay Trail with a Celeron/Pentium level CPU and charge that price. That blurb did make it sound like the keyboard dock and docking station are included in the package which does significantly ups the value proposition, yet still too high. For the Q704 it'll be a great machine (if it solves the horrible throttling issue the Q702 had), yet it'll likely be $2000+ maxed out. But 12.5" to me at least is a great size, but the weight for that is still too high (both the tablet and dock, 10-15% reduction increases the attractiveness a lot.

Anyways I ran a set of tests on my Venue 8 Pro, I ran them 5 times each (except Bmark) on Chrome to eliminate outliers. Here is the list:

Sunspider 1.0.2 - 537.06 ms
Sunspider 0.9.1 - 561.98 ms
Mozilla Kraken 1.1 - 5893.58 ms
Google Octane V1 - 5457.6
Browsermark 2.0 - 2732.67
WebXPRT - 492.83

Browsermark gave me some issues, and I think this number would be closer to 3000 but alas I gave up on that particular benchmark when it didn't run fully a couple times in a row.

Other than that though, and a bit lower WebXPRT score, it runs pretty well, more or less the same as the Asus T100.

Qualitatively though, I'm very happy overall with the experience with Windows 8.1 on the 8" screen, everything is responsive and works well.

Bring on Airmont -> Cherry Trail.

it's weird. i ran geekbench 3 and i got 618 single-core and 1907 multi-core. how can it be that much lower than the 785/2479 number. the only thing i can think of is the power profile which is on dell/balanced but there is no other choice. ???

ok so i figured out my issue with these numbers. i ran those tests not being plugged in. i just ran a bunch again and got these scores, and are much more favorable. i only ran once as they won't change that much.

geekbench 3 - single =786, double = 2442
webxprt - 555
sunspider 1.0.2 - 416.6ms
sunspider 0.9.1 - 529.2ms
kraken 1.1 - 5484.2ms

octane v1 was surprisingly lower at around 5300.
octane v2 is different and likely more demanding but i got 5142.

big jumps and now that just makes bay trail look even better.

Idle-Load delta shocking high. Why is this? One test is not enough though, at least a second device for verification is needed.

No idea how reliable their test is, but I think the delta seems OK because high load may stress not only CPU/GPU, but pretty much every other device subsystem.
7.9W delta - sure it worse than 5.1W delta out of Galaxy Note 3, but... I have no idea what notebookchech uses to stress android devices, but I doubt they can find on android something similar to power virus such prime95+furmark.
Also T100TA seems more efficient than Surface 2 which has performance delta 11.7W.

Delta for A6-1450 is lower and that's a 8W TDP APU.

wow. that looks ugly

I don't mind the looks (thickness) personally as long as the price is right.

The main thing I am disappointed about is that the screen doesn't fold flat though for a true tablet configuration. I am not sure I'd find the 300 degree "Tablet Stand" mode useful.

While in the Acer Aspire V5 122P review - http://www.notebookcheck.com/Test-Acer-Aspire-V5-122P-61454G50NSS-Notebook.92357.0.html - that same A6-1450 has a delta of 10.9W. Or how about the Surface 2 RT - http://www.notebookcheck.net/Review-Microsoft-Surface-2-Tablet.105780.0.html - that has a 11.7W delta?

Much as I like to get a rough idea of power consumption from notebookcheck's reviews I know full well that their accuracy is quite questionable. Which isn't too surprising given that they have how many different reviewers, all of whom may well be using different equipment/slightly different testing methods?

Testing methods should be the same. I was aware that the first A6-1450 test had a much bigger delta. We need at least a second Bay Trail test to verify Bay Trail results. For A6-1450 I don't know, hopefully we get a third test sometime. From 23W Load to 13W Load seems odd. I mean the Samsung ATIV Book 9 requires a fan whereas Bay Trail don't need a fan.

maybe it is because baytrail doesnt hang around its max draw as often as amds parts...also the heat output may vary based on the efficiency of the architecture

Seriously nothing against notebook check but there power measurement is meaningless because they are NOT measuring the power draw at the component level but from the wall outlet. They are basically measuring the power draw of the power adapter. Look at the Asus Transformer Book T100 for example the max power draw is 11.8W, the charger the T100 comes with is rated for 10W, typical external power adapter efficiency level is around 85%, so a 10W rated adapter would draw 11.76W from the outlet. Which is pretty much exactly what notebook's check's number is. This doesn't mean that the Bay Trail system is using 11.76 W under max load, it could be using 3W it could be using 8W, it could be using 10W, we don't know how much of the power from the adapter is using to charge the battery and how much is used to actually power the device. Unless you can separate the two the power number from notebook check is meaningless.

Having a higher power draw on notebook check actually isn't a bad thing... it's actually a good thing all things being equal (device draws the same Watt) it means the device's battery will charge faster while you are using it, a low draw from the wall could mean the device won't charge (or charge slowly) while you are using it. Even then different companies have different charging strategies for there batteries. Some (like Lenovo) won't charge the battery until a certain battery level is reached (to reduce charge cycles), others will use a slower charge instead of a fast charge to minimize heat and prolong the life of the battery, etc.

The battery life test (normalized for battery size) is still the only way to get an ideal of how much power the device actually uses unfortunately.

Why Idle measurements are much lower then?

Anyone care to comment on the Wi-Fi connectivity of the T-100 and maybe the Dell Venue 8 pro?

Is it close to a full size laptop? I have an older Acer android tablet, and it is basically unusable without an extremely strong Wi-Fi signal. Page loading is agonizingly slow, and many times it just sits there with the page partially loaded. And this is sometimes when it said the signal is good strength.

I haven't had much of an issue with WIFI, interestingly it connects at 130 Mbps whereas my laptop (Lenovo) connects at 65. The signal varies, but even 3 bars and I can't tell the difference with 5 bars.
