The Intel Atom Thread

[Khato]

I was told that screen resolution has an impact since backlight has to be increased with higher native resolutions due to higher density of LCD components.

Correct, pixel density is one of the factors that affects the transmission factor of the LCD as the width of the pixel structure doesn't change much for a particular process regardless of whether its producing 100 dpi or 300 dpi. That's why the IGZO process reduces necessary backlight power for a given brightness compared to their competition. (IGZO also has a marked advantage in the actual panel power consumption, which is the other reason why higher resolution requires more power.)

Exactly, and that's why TDP, claimed W for SoC, etc. don't matter that much in the end.

For the typical battery life tests, yes. But that's only because they have yet to move beyond consumption models. Which are applicable for the majority of what's currently done on mobile devices... but fall flat soon as someone wants to use up their battery playing a game. Or performing productivity workloads that actually put a meaningful load on the SoC. That's where the SoC power consumption will matter, and we might be getting to the point in both performance and efficiency where those usages actually become valid possibilities with reasonable battery life. (Instead of an anemic 1-2 hours.)

Not bad but nothing exceptional given the 10" screen
that has low max luminosity...

T100's 278 cd/m² maximum luminosity is pretty dim by modern standards.

Also , it s weird that when pushed the beast manage
to eat more than what would be expected...

I plugged in the system while installing OS updates and our test applications, but the battery indicator continued to trickle down. Windows said the Transformer was charging—it just wasn't charging fast enough to offset whatever battery power I was using.

Theses are at TR , a site that is highly intel friendly ,
heck , they did their VPB test at 100 nits , not that
important since they didnt have to bother looking
at the film.....

Great, can't wait to see how Ubuntu 64-bit behaves on such a device, keep us informed :thumbsup:

Larabel from Phoronix also bought a Bay Trail, so we will surely soon see some Linux benchmarks from him.

Had problems trying to get the live USB booting (the reviewer at some site had the same problrms)

Disabled secure boot, created live USB from x64 12.04-3 and 13.10 which are supposed to work with uefi. No luck... USB light flashes, but nothing happrns(same thing with secure boot on). USB drive boots properly on desktop with bios

Will try more later tonight

Why must you supply only half a quote in order to paint Baytrail in a bad light?

The T100 had close to a full charge when I took it out of the box. I plugged in the system while installing OS updates and our test applications, but the battery indicator continued to trickle down. Windows said the Transformer was charging—it just wasn't charging fast enough to offset whatever battery power I was using. Fortunately, the charging issue sorted itself out when the battery ran dry for the first time. Ever since that first full discharge, I've had no problems charging the T100 while using the device.

I'm really not feeling the low resolution Bay Trail tablets. I'd like all of these to have 1080p or higher minimum for a 400$ and up pricepoint, personally. To be fair, though, a lot of these SKUs are convertibles with keyboards and the like which easily accounts for the price difference despite the lower resolution. So it's a decent trade-off I guess.

That said, there are quite a few 1080p Bay Trail tablets - and i'm eyeing them closely for purchase as gifts for family members during the holidays. From everything i've read BT has met my expectations and more. Definitely going to buy at least one in the coming weeks.

New Bay Trail-D Mini-ITX Line by ECS: www.anandtech.com/show/7453/ecs-reveals-bay-traild-miniitx-line

...the three products will offer a Pentium J2850 (quad core, 2.4 GHz), a Celeron J1850 (quad core, 2 GHz) and a Celeron J1750 (dual core, 2.4 GHz). All systems are paired with Intel HD Graphics (Ivy Bridge based), one mPCIe 2.0 x1 slot, one USB 3.0 port and two SATA 3 Gbps, as well as two COM ports.

 

[Shivansps]

Thats probably because they are all in a price fight at this point and testing the market, Asus using Z3740 leads me to belive that 1080P versions with Z3770 are on the way too, that is also a good excuse to charge more than what the display swap cost.

 

[monstercameron]

@shivansps it seems like the z3740 cant quite get to e-350 performance outside of synthetics...

lack of viruses (for now) on Windows RT + option for full office? (otherwise, android/iOS would fit the niche)

 

[liahos1]

still not a great reason imho. if you can get comparable or better performance at the same price for full windows why not take that.

 

[CHADBOGA]

Why must you supply only half a quote in order to paint Baytrail in a bad light?

Because he wants to portray all Intel products in the least favourable manner possible.

 

[Arachnotronic]

That seems like a weak argument.

 

[JustMe21]

He also failed to notice that the 8" Windows 8.1 (not RT) tablets come with Office 2013 Home and Student, which normally retails for $140 by itself. Just remember, the bigger 10" and 11" Windows 8.1 tablets don't come with Office 2013 Home and Student for free.

Three reasons I would chose a Windows 8 tablet over an iPad is for USB capabilities, to be able to use a Bluetooth Mouse, and the ability to install a different OS.

COD4 and CIV5 runs way better than in the E-350, looks like twice the FPS, but im not sure about the details or resolution used. Other games i do not remember because it was years ago, like Fallout 3/Black ops or i never tested them.
I cant get any conclusion or attempt to do a 1-1 comparison on an E-350 based on that, no details levels or resolution are present on any of those videos.

BTW, even Black ops looks faster if i consider this

Fallout 3 also looks faster.

The IGP on BT is a dissapointment regardless, even if it can catch up with E-350 due to superior CPU, the E-350 is a 4 year old APU, while its a huge improvement over old ATOM, is not enoght. I was wondering today if that is not the reason for choosing the Z3740 over the Z3770, less CPU turbo means more room for igp turbo, that could also explain why the Z3740 is giving best scores than the test platform of Z3770.

well, E-350 TDP is 18W

(BT paper TDP is 3W, plus some buffer on how you calculate TDP)
let's say BT TDP is 6W

1/3 the power consumption for roughly the same/slight inferior performance? (and remember, most power is output as heat... this means you get 2/3 less heat as well)

when you factor in the lack of i/o and intels 22nm advantage it seems kinda meh but intel does have the lead in cpu perf and power draw which makes this a suitable chip for THE RESURGENCE OF THE UMPC! :twisted:

Bay Trail-T didn't consume more than 2.5W running Cinebench. Where in the hell are you pulling those numbers from?

well, Im talking about how TDP isn't <max power draw>, and Intel / AMD calculates TDP differently...

so worst case, I doubled it to 6W, and it is 33% of the TDP of AMD

if you want to say 3W, then it's only 17%

Heres a list of 9 Bay Trail tablets launching now or soon: www.umpcportal.com/2013/10/9-baytrail-tablets-and-2-in-1-pcs-ready-to-go/

I noticed those are all Windows Tablets.

Do we have any idea when the Android Bay Trail Tablets will be out?

 

[Shivansps]

My problem with that is that the IGP is the same on the Z3740 than the one on Pentium J2850 with just a few more mhz, not even increasing the clocks to the 1.1-1.2ghz range...

My mixed feeling with BT is that in kind of expecting Intel to greatly improve IGP on the next version, like a full HD4000 or a Haswell GT1.

 

[Khato]

Good guess. And yeah, there's no question that Baytrail is a bit underwhelming in that respect. I expect it's a result of the cost, aka die size, factor weighing a bit more heavily than it should have in comparison to graphics performance. Whereas with the transition to 14nm a straight-shrink of Baytrail would be down to roughly 50 mm^2... which leaves a lot of die space on the table for graphics while still having less area. Especially since it's going to need a certain amount of edge space for I/O if it keeps dual channel memory.

there should be 1 out in November with more to come in December and January. From my understanding there are about 20-25 android tablets in the pipeline. they are following the windows products based on Intel's OEMs wanting product out around the time of the 8.1 update (Free marketing) and intel spending about some extra time fine tuning baytrail for android
