Ahead of the release of Windows 8 and the onslaught of Windows 8-based tablets that will hit the market next month, Intel is taking the cover off the processor that many of these new devices will be powered by, the Intel Atom Z2760 previously known by the codename of Clover Trail. Intel is claiming that the Atom Z2760 is the beginning of a completely new Atom direction, now a complete SoC (system-on-a-chip) design that lowers power requirements, extends battery life and allows Intel's x86 architecture to find its way into smaller and more portable devices.
At it's heart, Clover Trail is based on the same Saltwell CPU core design that was found in the Medfield processor powering a handful of smartphones over in Europe. That means the Atom lineup remains an in-order architecture with a dual-issue command structure - nothing incredibly revolutionary there.
Unlike Medfield though, the Atom Z2760 is a dual-core design that still enables HyperThreading for four-threaded operating system integration. The cores will run at 1.8 GHz and it includes 1MB of L2 cache divided between the two cores evenly. Memory is connected through a dual-channel 32-bit bus to low power DDR2 memory running at 800 MHz and capacities up to 2GB.

Intel has been developing its WiDi wireless display technology for a few years now, and with Sandy Bridge and WiDi 2.x Intel had a workable platform for streaming video – despite it not being as reliable or as responsive as running a video cable. Today, Intel announced an update to its WiDi specification that brings the technology up to version 3.5 and makes it better than ever.
WiDi is a wireless transmission technology pre-loaded on mobile devices such as ultrabooks and other Intel CPU powered laptops like the Lenovo S series shown off at IFA 2012. Devices that have either a Sandy Bridge or Ivy Bridge Intel processor will be eligible for the 3.5 update and will see several improvements.
The most important update is a reduction in latency. Intel has managed to get WiDi latency down to 250ms on Sandy Bridge, and an impressive 60ms for computers running Intel’s latest Ivy Bridge processors. At 60ms, the user interaction with the OS is going to become noticeably more responsive. Thanks to this latency reduction, Intel is announcing support for not only running its WiDi software on Windows 8, but the operating system’s touchscreen interface as well. While using a touchscreen with a WiDi display might have felt less-than-responsive with older WiDi implementations, by bringing the latency down to sub-100ms levels, the action of touching UI elements and getting feedback in the form of display output should be fairly fluid.
Some other big changes with the latest WiDi update include support for streaming 3D video and compatibility with the Wi-Fi Alliance’s Miracast wireless display technology/standard. The Santa Clara-based company made it clear that it does not want to fight the Wi-Fi Alliance over which implementation of wireless display should be the 'industry standard.' Intel has stated that it wants to complement Miracast rather than compete with it. The company’s WiDi equipped devices with the 3.5 update will happily stream to Miracast certified receivers. The only potential issue is that Intel does not guarantee latency when using Miracast receivers. In that respect, Intel sees WiDi as being Miracast + its additional feature set on top that provides some additional functionality and certification beyond the base standard. There was no mention of AMD’s proposed wireless display technology, however.
Intel has further reduced battery consumption when using WiDi, and when using WiDi 3.5 users should see some incremental battery life improvements versus the previous generation. CPU utilization while streaming video has also been reduced to less than 10% on both Sandy Bridge and Ivy Bridge Intel CPUs.
The final major additions to WiDi 3.5 are on the receiver end of things. Thanks to Miracast support, WiDi-equipped computers will be able to stream to a wide variety of devices in addition to using Intel WiDi dongles. And while previous generation WiDi receivers were around $80, this time around receivers should be a bit cheaper. In the late 2012 to early 2013 time frame, new WiDi 3.5 receivers will be available for purchase. A new Neo TV box will cost $69.99 while a more traditional WiDi dongle from Netgear will retail for $59.99.
Some interesting new capabilities of the receiver units include the ability for dongles to be powered by the USB port on the TV (rather than needing a wall power adapter). Also, WiDi 3.5 will support USB ports located on the receivers (pending hardware manufacturer implementation) that will allow you to keep HID class USB devices plugged into the receiver. Those input devices (keyboard, mouse, track pad, game pad, basically anything that is classed as a Human Interface Device under the USB standard) will then control your WiDi connected computer over the same wireless link that is streaming video to your TV.
And, of course, WiDi 3.5 continues to support streaming 1080p video, HDCP2 encrypted streams (Blu-ray), DVDs, and 5.1 surround sound.
The WiDi 3.5 software update is already in the hands of OEMs, and a public download of the update should be available to Sandy Bridge and Ivy Bridge computer users sometime in October. The updated WiDi computers running 3.5 will be able to stream to Miracast or Intel’s own WiDi receivers. However, if you want the improved WiDi receiver(s) with USB ports, you will have to wait until early 2013 at the latest to get your hands on the hardware.
Also, you can watch a live demonstration of WiDi working on an ASUS Z77 motherboard in the video below.

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!
Image credit: PC Pro.
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."
