Apple A7 is 102mm2, exactly the same as Intel Silvermont(BayTrail).

The actual CPU core (not the whole die) is MUCH larger.

It's exactly what they are stating. It's been unofficially known for some time that the density of Intel's wires has been not as good as TSMC. AFAIK it's just been a cost tradeoff for Intel for multiple patterning the metal layers to get the density. Also wires get lower performance the smaller they are so density optimized isn't always the best when it comes to performance.

I believe intel optimizes for performance, not area. Seems to be worthwhile to them given their high margins and the relatively low chip sizes (compare ivy/haswell to trinity/richland).

One theory I've seen is that Intel doesn't optimize like the competition since once product comes first available their efforts are on to the next node. I imagine that will be changing.

So 102mm^2 for a dual core A7 compared to 102mm^2 for a quad core Baytrail. That must mean that Intel's design is half the size right?!

Sorry for the extreme case of sarcasm, but attempting to refute the statement that the A7 is much larger than Silvermont with respect to core area by providing total SoC die size kinda deserves such.

ASUS ships 500.000 T100 units in Q4/2013, expected shipments to reach +2 million in 2014



Asustek Computer has announced consolidated revenues of NT$39.9 billion (US$1.33 billion) for December 2013, down 19.06% on month, but up 6.28% on year with consolidated revenues for the fourth quarter of 2013 reaching NT$130.72 billion, rising 10.02% sequentially and hitting a new quarterly record.

Asustek's strong fourth-quarter performance also pushed the company's 2013 consolidated revenues to a new annual record at NT$463.30 billion, up by 3.26% on year.

Asustek's revenue growth in the fourth quarter of 2013 was mainly due to its better-than-expected notebook shipments as well as the strong demand for its 10-inch TransformerBook T100, which came to 500,000 units in shipments in the fourth quarter.

Since the TransformerBook T100 is currently seeing shortages in some markets such as North America, the company expects the device's shipments to reach at least two million units in 2014.

Their 22nm process is denser than TSMC's 28nm process (not sure if that's what you were asking).

Intel told not long ago they are denser.

This what Intel told, they also told their main focus with 14nm and 10nm is changing to higher density instead performance.

I didnt realize he was talking about Core size.

GloFo is capable of 4.7 ghz, so clearly they must be #1.

GF 32nm is very high clocking. But its also not power efficient. GF 28nm will improve on density and power efficiency, but give clocks a hair cut. Thats the point, you can't look at one attribute in isolation.

Am I wrong or Intel is admitting to have an inferior process than TSMC(on area scaling) at 20/22nm? And forecasting to be better at 16/14nm?
Nor really inferior, their process just has a worse density. It doesn't tell you anything about other characteristics.

Source? That just doesn't mesh with published information from either fab (or that chart).
No kidding. Intel's processes do 4ghz, TSMC is at 2.5ghz
GloFo is capable of 4.7 ghz, so clearly they must be #1.
Okay, this is a bit of a train wreck. I'm going to assume that jpniero's being facetious, but in case he isn't or neither of you are or whatever, Intel does have higher Idsats at lower Ioffs than any other competing fab. Their bulk processes have even historically outperformed IBM's PDSOI. With their last two nodes, Intel has been less dense than competing fabs at the same node label (e.g. 32nm vs 32nm), but that has not always been the case.

Still, transistor speeds are highly variable across designs. It's important to note design decisions when making these types of comparisons.

Granted that Lenovo Yoga 2 11.6" has the top bin Bay Trail-M (N3520), but I think it is just amazing to have four Silvermont atom cores @ 2.16 GHz (with 2.42 Ghz Turbo) fanless in a laptop that has no vents (other than the speaker openings at the bottom.)

I just wonder how large the heatsink is?

MSI Bay Trail-D (J18001) sub $60 due sometime this month:

http://www.fanlesstech.com/2014/01/60-bay-trail-d-motherboard-shipping.html



J1800 Bay Trail (2.41 Ghz dual core with 2.58 Ghz turbo)
2 x SO-DIMM
VGA, DVI, HDMI (The Biostar J1800NH and ECS BAT-I have just VGA and HDMI)
PCI-E x1 (a closed slot.... just like the Biostar J1800NH and ECS BAT-I Bay Trail Mini-ITX boards)
two SATA 3 Gbps ports
two usb 3.0
four usb 2.0
Gigabit Ethernet

A quad core for $10 more is supposed to come out shortly afterward.

AFAIK this brings the number of Bay Trail Mini-ITX consumer boards to four, Here are the other three:

Biostar J1800NH Mini-ITX--> http://www.biostar.com.tw/app/en/mb/introduction.php?S_ID=688#spec
ECS BAT-I (V1.0) Mini-ITX--> http://www.ecs.com.tw/ECSWebSite/Pr...goryID=1&DetailName=Feature&MenuID=17&LanID=0
ECS BAT-TI thin Mini-ITX--> http://www.tomshardware.com/news/ecs-v20-mini-lake-bat-i-v20,25679.html

P.S. The ECS website also lists a BAT-I2 (V1.0) which would bring the total of Bay Trail Consumer Mini-ITX to five, but so far no information listed--> http://www.ecs.com.tw/ECSWebSite/Pr...yID=1&TypeID=46&MenuID=17&childid=M_7&LanID=0

Microsoft wasn't the holdup.

Actually they were. Baytrail can run any 64bit version of windows. People have installed them on Venue 8 Pros.

But only 32bit win 8 offers connected standby and presumably only 32bit is eligible for the reduced licensing fees afforded 8" tablets.

It appears MS is tightly controlling the mini tablet category like they did netbooks. The whole batch of 8 inchers use 800 resolution.

That's not the case:
There is a build of Windows 8.1 that supports connected standby that is available right now, however there are some additional hardware requirements that have to be met by the OEM.

This is according to Anand on his live mobile show, at roughly ~1:02:00.

Pretty vague.

Are these hardware requirements imposed by MS on the OEMs? like screen resolution?


There is now a 1080p 8" tablet announced, but its got a higher price point and a z3770. Probably not a coincidence.

PCWorld.fr @ Google Translator said:
If you believe ComputerWorld , manufacturers of phones and tablets that want to get the most SoC Atom 64-bit generation Bay Trail will be based on the Android 4.4 kernel (KitKat) x86 64bit Intel has itself developed. The founder puts in some internal documentation Atom performance 64-bit before, eg, that photo editing is accelerated by 20%, publishing podcast 44%, creating a slideshow of 6 % and sharing photos of 4%, all this over a similar 32-bit chip.

Here's something a bit less vague. Check slide 6. Just to warn you, it's a straight PDF download link.

Basically, it's expensive -- it's a ~$70 penalty to the OEM to implement on a Haswell device. I stumbled on this completely by accident, doing my normal PDF hunting while searching for information on Broadwell and the 9-series chipset.
