Intel Burst and Active Power Management
Intel Burst Technology
Previous generations of Atom cores used boost technology but only exposed additional P-states to the CPU based on available thermal headroom. With Silvermont the x86 cores run at burst frequencies managed by hardware measuring thermal, electrical and power delivery constraints. The SoC is able to share power between the CPU cores and graphics or other included units.
The burst operating points can be adjusted dynamically based on thermal properties of the device (larger heatsinks, etc.) but there is very little overlap between what Silvermont is doing and what the Core series algorithms are doing with Turbo Boost.
These diagrams illustrate the capabilities of bursting and it is really this technology that allows Intel to compete with ARMs big.LITTLE designs with a single core design that scales power envelopes and frequency levels smoothly. Part of our testing of Bay Trail and the new Atom Z3000 series SoCs is to find out how often they are meeting their top frequencies and where they fall to after extended use.
Active Power Management
Intel provided some thermal imaging of Bay Trail to demonstrate the capability for these SoCs to dynamically power down when not being utilized. Obviously for mobile designs this is the real key for extending battery life of tablets and smartphones without sacrificing peak performance.
The top image shows a near fully utilized quad-core Atom Z3000 part with the red areas as the “hot spots”. The second image shows both modules (all four x86 cores) in a sleep state while the final image shows a fully gated SoC at its lowest power state.

What is the clock speed of the z3770 you are testing?
How could let Intel not talk about TDP… is it that bad?
It’s not great. The Z3770
It's not great. The Z3770 bursts up to 2.4 GHz with a base clock of 1.8 GHz.
Given that all the reviewers
Given that all the reviewers are benching and testing what is top of the line Atom Z3770 (with dual channel mem and turbo of 2.4Ghz), it is reasonable to expect that the current OEMs using the Clovertrail Z2760 in pricey tablets/hybrids would utilize the new top line Baytrail in similar pricey products?
Another thing to consider is how well or not well Intel has supported the current Atom lineup with buggy crash prone drivers that has ticked off a large number of owners for the past few years.
To top it off, Intel claims that the new Atoms will be found in low priced tablets by the end of the year and if so, those Atoms will be very low spec low clock single channel CPUs.
As you say, the proof of viability of Intel’s new Atoms will be in the price of their product pudding.

Many nutritionists believe that the best time to eat food is when a person feels hungry since
this is arguably the body’s natural way of signaling that our
energy supply needs replenishment. The cardinal sin committed by many endurance athletes is complete disregard of strength training for fear of slowing
them down by adding muscle.
Would be nice to see this on
Would be nice to see this on say a low power server system, perfect for File/Media Storage/Streaming as an option to a 35W TDP CPU.
maybe get rid of the h.264
maybe get rid of the h.264 encoder/decoder and make the GPU even smaller?
Poor AMD it looks like they
Poor AMD it looks like they have lost this round already. 🙁 Well if we look at the bright side, it at least appears that their new chips seem to be producing decent performance numbers in graphic intense applications.
This is a stunning upgrade
This is a stunning upgrade from clovertrail .. Intel has finally arrived in this space.
interesting to see the higher
interesting to see the higher 3dmark performance on android!?
also, ST performance on cinebench looks equivalent to a A64 3000+ from 2003, but obviously 4x cores and the power efficiency can justify the 10 years difference.
Considering that this isn’t a
Considering that this isn’t a desktop chip and has much lower power consumption, I think your comparison is a bit ridiculous.
U can’t really compare a 2003
U can’t really compare a 2003 desktop cpu with this
Architectures have changed and in 20003 u still

Besides I have compared a core u duo 1.8 ghz cpu with this this baytrail and the baytrail seems

Is it possible to do a NAS
Is it possible to do a NAS benchmark for the CPU?
I currently use a DIY NAS and it can easily max out a gigabit connection, but it is using a a CPU (AMD APU) that pulls 65 watts. Handling NAS loads and media streaming, and VPN access does not put high load on the CPU.
I don’t like premade NAS devices because there are many that cost $1000 with no hard drives and still perform worse than a $550 NAS including 6TB of storage.
It would be awesome if this CPU can work well in a low powered and near silent NAS build

What kind of test would you like? How could I get a benchmark that is relavant?
Isn’t the temash HP laptop
Isn’t the temash HP laptop based on HDD? Did you change the Temash to a SSD to compare against BayTrail?
Also, how about PCMark / Vantage results for comparison?
Thanks.
untill i dont know die size
untill i dont know die size of this Atom and its max TDP I cannot apreciate it. Intel avoided to give those numbers, so something is strange.
lets consider that in this moment AMD Jaguar A4-5000 get a die schrink at 22 nm . Then will beat hard the ass of Intel in power, graphics, performance and whatever you want.
Beat Intel?really?better hope
Beat Intel?really?better hope Intel doesn’t offer this with 3.5 w.if Intel does I’m pretty sure they could up GPU frequency.at 3.5 they would beat and in all but heavy gaming .nobody do hardcore gaming on tablet.
Are your benchmarks using a
Are your benchmarks using a single core, or all available cores? This is very important, as you directly compare to AMD’s competing Temash 1250, which is only a dual core part. You also fail to specify that it’s dual core in the spec breakdown, though you give Clovertrail that privelege.
Not getting my tinfoil hat out or anything, and my point is moot if the benchmark only tests a single core, but you should probably highlight (and bold, and underline) core counts as they play a huge role in benchmark results if multithreaded…

Aw, this was an incredibly nice post. Finding the time and actual effort to generate a superb article… but what can I say… I hesitate a lot and don’t manage to get anything done.
