Some numbers from an AT member worthy of a read :

Here in Germany the J1900 became available before the J1800 at my favorite retailer: I got a GIGABYTE GA-J1900N-D3V (quad core) some weeks ago, put it into a mini-ITX case with a 90Watt PicoPSU (needed the 12V 4pinconnector) and a 60Watt 12V notebook power supply.

Added a Crucial C300 for storage and went ahead testing with Window 8.1 (the only thing that worked with the initial BIOS) and then with Win7, CentOS 6.5, Fedora 20, Android x86 after the new BIOS made that possible.

Did the same with a GIGABYTE GA-J1800N-D2H (dual core) two weeks later and benched them side by side.



First off, both CPUs *always* work at their top speeds unless idle. So that's 2.41GHz for the J1900 and 2.58GHz for the J1800. The nominal speeds aren't ever used, and I guess their main reason for existance is because it make them look nicer in the Intel charts. And perhaps their predecessors were actually fixed clocked at that value and I guess you'd still get those if you disable turbo in the BIOS.

Again, even running a Prime95/Furmark combo for hours, won't get any of these CPUs to drop their speeds to nominal: Turbo speeds aren't just for single threaded loads.

That mainly means that the normal clock difference between the J1900 and the J1800 isn't all that big, just 170MHz on the CPU, while the GPU on the J1900 is a notch above the J1800.

That again means, that the main difference between the two is the number of cores (2 vs. 4) and the amount electricity they consume and turn into heat.

It doesn't matter in terms of normal office applications or browsing: The J1800 typically came 170MHz out ahead on things like Kraken or Octane and both are fast enough at 1080p for most users. Yes, side by side with a top-notch 100Watt desktop CPU they are a tad slower, but nothing to loose hair about: Again not-an-Atom any more!

I managed to get the J1800 to 6.3Watts at the power outlet (behind the 60Watt AC/DC and the 12V PicoPSU) with 8GB of LV DRAM, the Crucial SSD, video off on a 64-Bit Windows 8.1 idle desktop. The J1900 will take 3 Watts more (9.3) for the same setup, which seems to indicate that one half of the J1900 can't go to C7 if the other one is still more or less awake.

There is of course also another Ethernet port, more USB 3.0 but none of them were used during the low-power tests.

On the other end, a combined Prime95 and FurMark will result in 28Watts on the J1900 and in 22Watts on the J1800. Core power consumption measured via CPUIDs HWMonitor showed 2.29Watts for the J1900 cores and 2.4Watts for the J1800 cores, while the package consumption was put at 6.85Watts for the J1900 vs. 6.54Watts for the J1900.

This oddity was consistent and I can only explain it by HWMonitor only measuring one of the two CPU blocks on the J1900, but the full GPU block (and remainder of the SoC), which is clocked a little higher on the J1900 under load.

The passive cooling solution on the Gigabyte J1900 board was not capable to dissipate all the generated heat on the Prime95/Furmark combination which generated 28Watts at the socket. About 30 minutes into the test at the threshold temp set in the BIOS (I used 90°C) the CPU started to throttle to 1.3GHz and went back to 2.41GHz once the temperature sank sufficiently.

The J1800 never reached or exceeded 50°C under the same load.

That all points at the 10W TDP as bolloks or only valid for nominal CPU clocks, but I'm not going to complain, because under any normal or reasonable load, even the J1900 never throttles.

Not so sure on this pricing. I can grab a G3220 Haswell Pentium and an H81 motherboard for around 110 bucks....Seems like 70$ should be the go to mark for this platform, for both a mobo + CPU. Unless i'm REALLY missing something.

Yeah, you are missing something.

On the GA-J1900N-D3V, the CPU TDP is 10w with good performance/watt. The board size is Mini-ITX. The SoC is passively cooled. This board has legacy IO and 2x GbE Ethernet. And this isn't meant for all of the same markets as the G3220.

But this board will do GREAT for replacing my router, I can use ALL of these features... so I have one on the way. I'm sure others with size and power requirements and not GPU requirements needing legacy IO can make use of this too. I wouldn't use it as an HTPC though.

(My only wishes are that it had a PCI-e connector, although I understand PCI for the target market. But it does have Mini PCI-e which I can use for my purposes with a breakout, though the slot lacks USB. Why? And why couldn't Gigabyte break out the rest of the USB 2.0? The SoC has 4x or 6x USB 2.0, but they only break out 2 on a header...)

And also regarding TDP on these chips: if the thermal threshold will allow it, they are specced to exceed it. I found that interesting.

PassMark

Atom z3745

http://www.passmark.com/baselines/V8/display.php?id=20177836568

z3740
http://www.passmark.com/baselines/V8/display.php?id=21968332795


think as rumored a surface 3 mini maybe could be z3745? or better you think?

I'm hoping some w8x64 tablet 8"

Pretty good performance boost.
~10% better CPU performance, ~13% better graphics performance. Higher boost clocks in action.

It would be nice if Anand updated their Bay Trail tests with the new models and the latest drivers.

Intel aggressively promoting tablet CPUs in China

Intel has resorted to an aggressive pricing strategy to promote sales of its tablet-use processors, particularly in China, a move which apparently will take on Qualcomm and MediaTek, while ramping up its market share, according to industry sources.

Prices of Intel's mainstream quad-core tablet CPUs have dropped to below US$5, which are almost on par with those offered by China-based chipset suppliers such as Rockchip Electronics and Allwinner Technology and even below those available from Nvidia, Qualcomm and MediaTek, said the sources.

Consequently, the number of Intel-based tablets is likely to expand in a great proportion as more and more China-based brand and white-box tablet vendors are expected to use Intel's tablet CPUs to develop new products, the sources revealed. [...]

Bay Trail-powered Asus Chromebooks launching soon

Asus launched its first Chrome OS device this year: the $180 Asus Chromebox. It’s a tiny, affordable desktop computer with a Celeron CPU that’s a surprisingly capable device for the price. An even more powerful model with a Core i3 Haswell CPU should be available any day now.

Now Asus is getting ready to expand its line of Chrome devices with two new laptops. We already knew the Asus C200 and C300 Chromebooks were on the way. But now that retail shops are starting to list the devices, we have a better idea of what kind of hardware to expect.

Asus C200 Chromebook – $249

The Asus C200 is an 11.6 inch laptop with a 1366 x 76 pixel display, 2GB of RAM, and 16GB of storage.

It’s powered by an Intel Celeron N2830 processor, a Bay Trail chip that has a maximum TDP of 7.5 watts. That would help explain why Asus promises “all-day battery life.”

I’ve seen a variety of prices for this model, but it looks like the suggested retail price is about $249.

Asus C300 Chromebook – $350ish

Asus will also offer a model with a larger, 13.3 inch display, 4GB of RAM, and 32GB of storage.

This model sports the same Celeron N2830 processor as the smaller Chromebook, but seems to have a higher price tag with most stores listing the Asus C300 Chromebook for between $330 and $360.

Talking about the T100... now that it costs $349 (64GB) it's the best selling laptop @ Amazon.com, beating the popular Intel-based $199-249 Chromebooks. :)

It is a very, very balanced machine overall, taking price, performance and form factor in consideration. If the design/build was just a bit better, it would have been almost perfect in that regard.

Intel/MS need to encourage more designs like this.

They need better distribution as well. I have yet to see one of these or even the dell venue 8 pro in a retail store where I live, and I have looked in both best buy and micro center. If Intel is subsidizing manufacturing costs, seems like they should put some resources behind a strong retail presence.

I even went to microcenter to look at the venue 8 pro, since seems like a steal at their price of 199.00. They had a good supply in stock, but not one on display.

Yes. I was wondering what the advantage was of the $249 Asus over the $199 Acer C720? Better build quality? Better battery life than 8.5 hours because it is baytrail? I'm guessing the Asus still needs a fan because it is 7.5W? Still, it's nice to see Asus jump on the Chromebook bandwagon.

I agree... T100 is a very good bang for the buck
you get a pretty good 10+ hour lasting tablet that turns into a small x86-capable windows notebook when you need it.. best of both world IMHO

is there any J2900 board out yet? I might pick up one of them or J1900 to build a silent web+basic office PC for my parents (they're still on an old P4 2.8GHz system)

Here is the fourth Bay Trail-D Mini-ITX board that I know of to show up in retail:

ASUS J1800I-C

http://www.newegg.com/Product/Produc...82E16813132100

13-132-100-TS


$79.99 plus $6.98 shipping.

(Overall a pretty basic board. The only major thing to note is the presence of a half length Mini-PCIE)

One of the most annoying things with some of thoses MBs is that they have a single USB3 port , how do you do if you want to transfer some data from an external drive to another..??

Some or all? I quickly looked and couldn't find a single board with more than 1 USB 3 port. Though not for the same market Atom E3800 supports a single USB 3. Is that a Bay Trail limitation or did I miss some MB?
