Yikes, what went wrong with those -D SKUs! Lower clocks, higher TDPs, worse memory bandwidth, worse graphics...

More concerend about the RAM limitations. 2 and 4 gb. Seriously? You can work with 4 gb but 2 is a joke assuming that thing should run windows 8.

Last word on BayTrail-T is that it doesn't even support x86-64. Still waiting for a real confirmation on this. Personally I care more about the lack of registers than lack of address space.

Was going to say, perhaps it's limited in RAM for a reason.

Intel have missed where the industry was heading on tablets. These look too stripped down in order to get the lowest power draw they can get. Sure they'll get an extra hour browsing, but at what performance cost?

Three days too late.

You are aware that these two D SKUs are for tablet not desktop? -D SKUs uses DDR3L instead the more efficient LPDDR3, maybe that's why they have a slightly higher SDP. 2GB are on the low side for a Windows 8.1 tablet and I wouldn't buy such a device with such little RAM to be honest, 4GB should be fine on the other side for a tablet. If these two D-SKUs are aimed for Windows 8.1 it's a joke. Sorry Intel but 2GB for a next gen tablet generation is way too low. But maybe they are aimed for Android, who knows.

Why don't you wait for the launch in just over a month? ;)

SDP will only count the chip's power draw, not the memory or anything else.

Argh, didn't notice that was SDP not TDP. I'll wait until we see a number with an actual meaning before I start worrying :p

Regarding the sentiment that 2 GB of memory isn't enough for tablets... then I guess that basically every single tablet currently in existence is inadequate? (The handful of tablets with more than 2GB of memory are all x86 based.) Besides, that limitation is only in place for the lower end SKU with single-channel memory - if I had to guess that would be targeted at mainstream devices that want to keep the BoM as low as possible. (That combined with the fact that tablets have no need for massive amounts of memory are the reasons why 512MB-1GB is still typical for tablets.)

Depends what OS you put on it. 2GB should be plenty for Android, but I would expect at least 4GB for a Windows 8.1 device.

I do hope those are physical cores instead of single core + Hyperthreading. Intel Atom Z2420 on the Asus Fonepad that I've used is a decent performer but somewhat lacking when it comes to multitasking and UI transitions. It lags a little whenever something(even automatic updates) runs in the background.

Well, hence why there's a SKU that supports 4GB of memory :) But actually I don't expect that 2GB would be too limiting an issue on Windows 8.1 even provided that you don't go too heavy on the multitasking. With the 8GB+ of memory that most enthusiasts have we're used to seeing rather high (2-3GB or more) 'idle' memory usage from Windows... but that's only because of optimizations Microsoft put in to increase responsiveness back in the days of spindle hard drives. When you have 1-2GB of system memory the idle footprint drops down to below 0.5GB. (http://www.anandtech.com/show/5630/indepth-with-the-windows-8-consumer-preview/16 near the bottom for example.)

They are physical cores. Intel removed hyper-threading with the Silvermont architecture to optimize power - better to spend a bit more die size and have more cores that you can fully power gate than to have hyper-threading logic 'wasting' power on single threaded workloads. Such is covered in Anandtech's Silvermont Architecture article - http://www.anandtech.com/show/6936/...cture-revealed-getting-serious-about-mobile/3 - in the fifth paragraph on that page.

In general I've seen tables where # of cores and # of threads to show that. I personally haven't seen a case where something listed as 2-core really meant 2-thread. So if a table says 2 core, I'm pretty sure that means 2 physical cores.

I think 2gb is enough if you have decent IO to back it up.

Granted, most mobile SoCs these days don't but...

I get by with 2gb on Win 8 on my ATIV. It's not ideal :biggrin: but I think if the internal drive wasn't so slow it wouldn't be a problem at all.
