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.

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!

The Register is back with more information from Hot Chips about Intel's Xeon Phi coprocessor, which seems to be much more than just a GPU in drag. Inside the shell you will find at least 50 cores and at least 8GB of GDDR5 graphics, wwith the cores being very heavily modified 22-nanometer Tri-Gate process Pentium P54C chips clocked somewhere between 1.2-1.6GHz. There is a brand new Vector Processing Unit which processes 512-bit SIMD instructions and sports an Extended Math Unit to handle calculations with hardware not software. Read on for more details about the high-speed ring interconnects that allow these chips to communicate among themselves and with the Xeon server it will be a part of.
"Intel has been showing off the performance of the "Knights Corner" x86-based coprocessor for so long that it's easy to forget that it is not yet a product you can actually buy. Back in June, Knights Corner was branded as the "Xeon Phi", making it clear that Phi was a Xeon coprocessor even if it does not bear a lot of resemblance to the Xeon processors at the heart of the vast majority of the world's servers."

Tagged: asus, acer, Intel, atom, eee pc
2012 has been a very tough year to be a manufacture of mobile products and not too easy on the designers either. We started off with the Ultraboook form factor, specifically the challenge to make parts which could allow the ultrathin design to be functional in the real world while still aiming for that $1000 price point. The prices of SSDs have come down and the processors have also marginally dropped in price but the materials required to make a sturdy chassis of exceptional thinness have not.
Then Microsoft decided to make things interesting with their Surface tablet, which is a wonderful platform to show off Windows 8 on but not the best way to maintain a relationship with mobile manufacturers. Regardless of the price that Microsoft chooses to release the Surface at, each Surface sale represents a lost sale for another mobile manufacturer. Acer, for one has had no problems voicing their complaints about a software company muscling into hardware territory.
Today we heard from DigiTimes that ASUS is dropping their Eee PC line, along with Intel's Atom processor and Acer is dropping netbooks altogether. While part of the problem with the Intel's Atom is that it has always had a hard time providing users with the computing experience they desire, dropping the entire form factor implies more problems that simply performance. Manufacturers could build netbooks with AMD's Trinity or even NVIDIA's Tegra depending on the agreements in place with Intel, however the two top tier mobile manufactures have straight out dropped the form factor, with only MSI staying in the market. While the netbook may have only been of use to a certain younger crowd with limited money and expectations there were certain Eee PC models designed for the desktop which made decent low powered internet access machines which are also going the way of the dinosaur which may be missed a little by a larger audience.
The effective death of the netbook will have an effect on manufacturers like Pegatron and some sections of Intel, the real question is whether the end user will even notice or if they were already only considering a 13" laptop or Ultrabook.
"Intel may be forced to adjust its roadmap for PC-use Atom processors as the top-2 netbook vendors – Asustek Computer and Acer – both plan to stop manufacturing related products, according to sources from notebook players.
Asustek is already set to halt its Eee PC product line and officially phase out from the IT industry after completely digesting any remaining inventory. As for Acer, so far, the company has not yet made any plans to open new netbook projects, indicating that the vendor may also plan to step out of the market."

Tagged: sandy bridge, Ivy Bridge, Intel, core i3, 35w
Back in March of this year, Intel launched a slew of third generation Core Ivy Bridge processors. At the high end sat the Core i7-3770K with 4 cores, hyperthreading, 3.5 GHz clockspeed (3.9 GHz Turbo Boost), 8 MB L3 cache, and a 77W TDP for $332. The lineup went down in features – and price – from there all the way to the Core i5-3330S. The 3330S had four cores, 6 MB of L3 cache, a 65W TDP, and a clockspeed of 2.7 GHz (3.2 GHz Turbo Boost). Further, just about every CPU that was not a K, S, or T edition came equipped with the older HD 2500 integrated processor graphics. While the list comprised 18 new processors, the lower-end Core i3 Ivy Bridge CPUs were noticeably absent.
Fortunately, FanlessTech has managed to get ahold of pricing and specifications for five of those lower cost Intel chips. The new additions to Intel's lineup include three Ivy Bridge processors and two Sandy Bridge CPUs. Specifically, we have the i3-3240T, i3-3220T, Pentium G2100T, Pentium G645T, and Pentium G550T. All of those parts have a TDP of 35W and are priced very affordably.
|Model||Cores / Threads||Clockspeed||L3 Cache||TDP||Launch Price ($USD)|
|i3-3240T||Ivy Bridge||2/4||2.90 GHz||3MB||35W||$138|
|i3-3220T||Ivy Bridge||2/4||2.80 GHz||3MB||35W||$117|
|Pentium G2100T||Ivy Bridge||2/2||2.60 GHz||3MB||35W||$75|
|Pentium G645T||Sandy Bridge||2/2||2.50 GHz||3MB||35W||$64|
|Pentium G550T||Sandy Bridge||2/2||2.20 GHz||2MB||35W||$42|
The Core i3-3240T and i3-3220T are dual core Ivy Bridge processors build on a 22nm process, and are priced at just over $100. The cheapest Ivy Bridge CPU is actually the Pentium G2100T at $75 so the barrier to entry for Intel’s latest chips is much lower than it was a few months ago. Intel’s second generation Core architecture is still alive and kicking as well with the Pentium G645T and G550T at $64 and $42 respectively.
Two specifications are still unkown: Turbo Boost clockspeeds (if any) and which version of processor graphics these chips will feature. On the graphics front, I think HD 2500 is a safe bet but Intel may throw everyone a curve ball and pack the higher-end processor graphics into the low end units – which are arguably the (computers) that need the better GPU the most.
Granted, these lower cost processors are not going to give you near the performance of the i7-3770K that we recently reviewed, but they are still important for low power and budget desktops. Bringing the power efficiency improvements of Ivy Bridge down to under $100 is definitely a good thing.
As far as availability, you can find some of the new low TDP processors at online retailers now (such as the Core i3-3220T), but others are not for sale yet. While I do not have any exact dates, they should be available shortly.
How would you put these low TDP dual cores to work?
