iXBT Labs wanted to see how the two most current generations of Intel processors compare when running identical tasks. To put the processors under maximum load they used Linpack and Furmark as well as looking at video playback. In the case of the Furmark and Linpack+Furmark tests it might have been nice to see a power versus performance metric, as better performance on the benchmarks could make a slightly less power hungry CPU even more attractive. However the video playback is a great example of what you can expect in the way of power draw as no one wants a faster processor to play their movie back at an increased speed, a 2 hour movie should take 2 hours to play. That makes the second metric a little more valuable for those on battery power. Take a quick peek at their 2 page article here.
"We measured consumed power and energy consumption of four configurations based on the same testbed and four different CPUs belonging to two platforms: Intel Core i7-2700K (Sandy Bridge) and Intel Core i7-3770K (Ivy Bridge), Intel Core i5-2400 (Sandy Bridge) and Intel Core i5-3450 (Ivy Bridge)."

Earlier this year, Intel showed off a small motherboard and processor combination that piqued the interest of many enthusiasts and attendees. The rather oddly named Next Unit of Computing (NUC) PC was originally intended to power digital signage, kiosks, and embedded systems (car PC anyone?). However, in response to the interest shown by enthusiasts, the x86 chip giant has decided to bring the super-small form factor computers to retail.
The Next Unit of Computing PC’s main attraction is its small size: the motherboard is tiny, measuring a mere 4” x 4.” For reference, the mini-ITX standard is a 6.7” x 6.7” motherboard, and VIA’s Pico-ITX form factor boards measure 3.9” x 2.7.” In that respect, the NUC is not the smallest PC that you can build, but it will be the fastest – and by a significant margin thanks to the bundled Ivy Bridge CPU.
While i3 and i5 editions were allegedly designed, currently Intel is only bringing the i3 to the retail market. Specifically, the CPU powering the NUC will be an Intel Core i3-3217U Ivy Bridge processor, and it will be soldered onto the motherboard. That particular CPU is a 1.8GHz dual core/four thread part with 3MB cache, and Intel HD 4000 graphics (there is no Turbo Boost functionality). Not bad for a small form factor PC!

The boards will have two SO-DIMM slots for RAM, an mSATA port for an SSD, and a mini-PCIe slot for a Wi-FI card. Intel is making two versions of the NUC motherboard that will differ only in IO. One motherboard will have 3 USB 2.0 ports, 1 HDMI output, and 1 Thunderbolt port. The other board will have 3 USB 2.0 ports, 2 HDMI outputs, and one Gigabit Ethernet jack. Intel believes that the Thunderbolt-equipped model will be more popular with consumers while the Gigabit-Ethernet and dual HDMI model will be used more by businesses.
Intel is reportedly sourcing several chassis designs for its custom form factor motherboard (there are at least two cases at present), and you will be able to build out a barebones system with one of the custom cases, integrated heatsink, and power supply. Additionally, when spec'ed out with the Intel i3-3217U CPU, 4GB of RAM, Wi-Fi card, and a 40GB Intel SSD, the company expects the entire NUC computer to cost around $399 in the US. The parts will be available for purchase in October, according to Engadget.
Hopefully, we will see OEMs take this form factor and make something cool with it. It's not clear which specific OEMs will be first to bring pre-built systems to market but they should be coming in the future.
Personally, I’m a big fan of small form factor computers, and despite the odd “NUC” name I’m excited to see where Intel takes this platform. If you were looking for a small but powerful computer to drive your next project, it might be worth keeping an eye on the NUC. What do you think of this sub $400, approximately 5” (with case) PC?

Tagged: Medfield, linux, Intel, fud, clover trail
Clover Trail is Intel's next Atom, the chip which refuses to die, representing an evolution of Medfield and the x86 instruction set. That didn't stop Intel from making a bizarre statement that Linux will not run on Clover Trail, even though it ran fine on Medfield and is an OS for x86 architecture chips. It is more accurate to say that some features of Clover Trail will not currently work under Linux, specifically the new power states introduced in the new Atom. Until the Linux kernel catches up to the new technology the new C and P states which can turn off the clock on the chip while still enabling 'instant on' will be unavailable which is a far cry from not being able to run on the chip at all. Thanks to The Register for immediately stomping on that FUD.
"SAN FRANCISCO: CHIPMAKER Intel has confirmed that it will not provide support for Linux on its Clover Trail Atom chip.
Intel's Clover Trail Atom processor can be seen in various nondescript laptops around IDF and the firm provided a lot of architectural details on the chip, confirming details such as dual-core and a number of power states. However Intel said Clover Trail "is a Windows 8 chip" and that "the chip cannot run Linux"."

Tagged: mineral oil, Intel
Intel has been dunking servers in oil for the last year and found the practice to be both safe and effective. Ironically it has been almost a year since we played around with mineral oil cooling – and when we did – we did not want to upgrade or fix anything. Intel agrees.
Intel inside, slick mess outside.
Often cooling a computer with a radiant that is not air focuses on cooling a handful of specific components and leaving the rest exposed to air. Gigabyte in their recent live presentation showed how the company reduced waste heat on the motherboard as it delivers power to the CPU as the latter likely receives more cooling than the former. With mineral oil you are able to more efficiently cool the entire system by immersing it in a better coolant than air.
This still makes Ken wake up in a cold sweat… is what we convince ourselves.
After a full year of testing servers, Intel has decided that oil immersion cooling should be utilized by more server hosts to cut costs over traditional air conditioning. In their test they used heat sinks which were designed for air and dunked them pretty much unmodified into the mineral oil dielectric. Apart from the mess of it – Intel engineers always carried cleaning cloths just in case – Intel seems to only sing praise for results of their study.
Of course Intel could not help but promote their upcoming Phi platform which you may know as the ancestor of Larabee.
Now the real question is whether Intel just wanted to shamelessly plug themselves – or whether they are looking so closely at alternative cooling solutions as a result of their upcoming Phi platform. Will we eventually see heat dissipation concerns rear their heads with the new platform? Could Intel either be sitting on or throttling Phi because they are waiting for a new heat dissipation paradigm?
Could be interesting.

The real news today is coming out of San Francisco, not Cupertino, as that is where the Intel Developer Forum is being held. If you missed Ryan's Live Blog yesterday you can catch some of what you missed over at Legit Reviews, with pictures of some of the slides and products which were revealed during the keynote address, up to and including a Core i7 powered Coke machine. This machine has a 46" 1080p screen. WiFi, a QR Code reader, camera and microphone ... as well as a coin slot and dispenser so you can actually get a can of Coke. It seems Intel wants to redefine the way people gather around the watercooler to chat. They did not state if it could play Crysis.
"Intel showed a slide that said Haswell will have uncompromised performance, all day use and greater than 10 days of connected standby. This all adds up to a mainstream notebook that has a connected standby power that is 20x better than we what we had in 2011 with the ‘Sandy Bridge’ architecture. The slide also said that Intel is targeting 2013 to launch Haswell, which supports the rumored Q2 2013 launch time frame..."

Ah, IDF – the Intel Developer Forum. Almost every year–while I sit in slightly uncomfortable chairs and stare at outdated and color washed projector screens–information is passed on about Intel's future architectures, products and technologies. Last year we learned the final details about Ivy Bridge, and this year we are getting the first details about Haswell, which is the first architecture designed by Intel from the ground up for servers, desktops, laptops, tablets and phones.
While Sandy Bridge and Ivy Bridge were really derivatives of prior designs and thought processes, the Haswell design is something completely different for the company. Yes, the microarchitecture of Haswell is still very similar to Sandy Bridge (SNB), but the differences are more philosophical rather than technological.
Intel's target is a converged core: a single design that is flexible enough to be utilized in mobility devices like tablets while also scaling to the performance levels required for workstations and servers. They retain the majority of the architecture design from Sandy Bridge and Ivy Bridge including the core design as well as the key features that make Intel's parts unique: HyperThreading, Intel Turbo Boost, and the ring interconnect.
The three pillars that Intel wanted to address with Haswell were performance, modularity, and power innovations. Each of these has its own key goals including improving performance of legacy code (existing), and having the ability to extract greater parallelism with less coding work for developers.

Tagged: seamicro, amd, Intel, xeon, piledriver, smug
To think that only 3 years ago we finally saw the end of the legal battle between Intel and AMD over the x86 patent makes today's news bring a smile to those with a certain sense of humour. Some of SeaMicro's new servers will be powered by Intel's Xeon line of processors, meaning that an AMD owned company will be offering Intel Inside. As AMD purchased SeaMicro for their "Freedom" 3D mesh/torus interconnect technology as opposed to an attempt to push Intel out of that particular make of server, this move makes perfect sense as AMD's bottom line will benefit from every sale of an Intel based SeaMicro server. It also opens up the choices available to the market as you will be able to purchase Piledriver based SeaMicro servers using the same interconnect technology.
From The Register we get more information on the Piledriver processors we will see in these servers, they will have eight cores and would come in three speeds; 2GHz, 2.3GHz, and 2.8GHz. They also infer that with this design you could have 512 cores and 4TB of memory in a 10U chassis which is enough to make any SETI@Home or Folding@Home team member drool with jealousy. On the Intel side they will use the 2.5GHz quad core Xeon E3-1265L v2 which means you would only have a mere 256 cores in a similar 10U chassis. DigiTimes also picked up on this story with more details on the insides of the servers, both Intel and AMD.
"SeaMicro is not longer an independent company, but you would not have guessed that if you were dropped in from outer space to attend the launch of the new SM15000 microserver in San Francisco on Monday afternoon. Advanced Micro Devices may own SeaMicro, but the company went out of its way to support the latest "Ivy Bridge" Xeon E3-1200 v2 processor from rival Intel as well as its own forthcoming "Piledriver" Opteron processor as new compute nodes in a new SeaMicro chassis."

Tagged: arm, Intel, atom, atom z2460, ARM Army
It is hard to believe that competing tech companies might make comments about their competitors that could be construed as negative but it has happened today as ARM calls Intel power hungry. From what DigiTimes could gather, a VP at ARM suggested that the Atom architecture consumes more power in total than ARM processors, though he stayed away from any comment about processing power per watt. This could well be because handset makers describe the Z2460 as more powerful than the ARM and only slightly less power efficient, something the ARM Army would rather was not mentioned. In the coming months consumers will get a chance to compare this for themselves as Windows 8 phones running on both Intel and ARM hardware will become available for direct comparison.
"While Intel has been making efforts to tap the handset processor market, the company still has a long way to go to catch up with ARM in terms of power consumption, according to Noel Hurley, vice president for Marketing & Strategy, Processor Division, ARM."

Tagged: ultrabook, Intel, haswell, cpu, 10w tdp
Intel’s next generation Haswell CPU architecture is set to lower the bar even further on power efficiency by requiring only 10W of cooling. As the company’s mainstream processor, and replacement for Ivy Bridge, it is set to launch in the first half of 2013.
Haswell will be based on a new socket called LGA 1150, and is said to feature incremental performance improvements over Ivy Bridge. Further, Haswell CPUs will include one of three tiers of GT1, GT2, or GT3 processor graphics along with the AVX2 instruction set.
What is interesting about the recent report by The Verge is that previous rumors suggested that Haswell would have higher TDP ratings than both Sandy Bridge and Ivy Bridge. Considering Ivy Bridge has several 35W desktop models, and a few 17W mobile parts, the reported 10W TDP of Haswell seems to indicate that at least the mobile editions of Haswell will actually have much lower TDPs than Ivy Bridge. (It is not clear if detkop and non ultra-low-voltage (ULV) chips will see similar TDP improvements or not.)
The 10W TDP would mean that ultrabooks and other thin-and-light laptops could use smaller heatsinks and suggests that the processors will be more power efficient resulting in battery life improvements (which are always welcome). The Verge further quoted an Intel representative in stating that "It's really the first product we're building from the ground up for ultrabook."
While the lowest-power Haswell chips won’t be powerhouses on the performance front, with the improvements over Ivy Bridge to the CPU and GPU it should still handily best the company’s Atom lineup. Such a feat would allow Haswell to secure a spot powering future Windows 8 slates and other mobile devices where Atom is currently being used.
Just the fact that Intel has managed to get its next generation mainstream CPU architecture down to 10W is impressive, and I’m looking forward to see what kinds of devices such a low power x86-64 chip will enable.
Stay tuned for more Haswell news as the Intel Developer Forum (IDF) next week should be packed with new information. Here's hoping that the desktop chips manage some (smaller) TDP improvements as well!
