Tagged: Ivy Bridge-E, Intel
Ivy Bridge was well known, just not in a good way, for its overclocking ability. We noted how sharply temperatures rose when frequencies were increased above factory recommendations in our i7 3770K review. Performance scaled well but, even with a decent aftermarket cooler, only did so while close to the boiling point of water. As Ryan described it,
To be fair, the 1.3v setting for this processor is on the upper limit of what you should be using according to many reports. The 22nm process is great for low power consumption but apparently not great for overclocking - higher voltages result in much higher temperatures than what we would have seen on Sandy Bridge.
...and a 24% boost in TrueCrypt. Pretty impressive results actually. But things are getting HOT under our Corsair H80 as it was unable to keep the CPU from breaching the 80C mark.
According to a roadmap received by VR-Zone, the pinnacle of Ivy Bridge-E until at least Q2 2014 will be the Core i7-4960X which, last month, failed to excite enthusiasts when benchmarks leaked. The story kept true from mainstream: it remains in Sandy Bridge-E's ballpark but requires less power. I am sure that Amazon Web Services will be thrilled...
We have wondered if Intel intends to punt this launch, fulfill commitments to Socket 2011 and nothing more, in preparation of Haswell-E. We may never see the i7-4960X overthrown, Xeon notwithstanding, until after the socket is retired.
But, now, we get to the hopeful news.
Unlike the prior generation, Sandy Bridge-E, the i7-4960X will not be a crippled Xeon architecture with disabled cores. While still a 6-core part, it will be so natively. Previously, the 6-core Sandy Bridge-E was an 8-core product with two disabled. This is an advantage because, assuming the locked cores could never be restored, their absence should allow greater overclocking headroom. Factor in the quad-channel DDR3-1866, which itself should have decent overclock potential, and users might have more room to be enthusiastic enthusiasts.
Overclocking capacity was the biggest unknown from last month's leaks. It is now looking a little more hopeful, at least for those with Sandy Bridge-E and an intent to replace their CPU before their motherboard.
And the pricing...?
According to the above table, originally from VR-Zone, the top two Ivy Bridge-E SKUs are expected to come in cheaper by $50-$70 than the Sandy Bridge-E models they retire. The quad-core i7-4820K is the exception, being priced within $5 of its ancestor.
Ivy Bridge-E is expected to launch in just a couple of months.

MSI recently launched the MS-9A29, which is a fanless small form factor (SFF) embedded PC. The new PC measures 196mm x 136mm x 43mm and weighs 1.2 kg. The MS-9A29 is encased in a small black chassis that is covered in fins to aid in passive cooling with the front and back banels hosting various IO ports.
Front IO includes four USB 2.0 ports and four COM ports. The back panel holds two RJ45 GbE jacks driven by two Intel 82583V NICs, one line out audio jack (Realtek ALC887 HD codec), two USB 2.0 ports, a single HDMI port, and one VGA port. Finally, the case provides two openings for antenna passthroughs.
Internally, the MSI MS-9A29 features an Intel Atom D2550 processor (dual core at 1.8GHz, 10W TDP), Intel GMA 3650 GPU (400MHz), a single DDR3 SO-DIMM slot (4GB maximum), and Intel NM10 Express chipset. The motherboard can be accessed by a removeable bottom panel on the case. The system supports one SATA drive, one mSATA drive, and two Mini-PCI-E cards. One mini-PCI-E slot can be used for a 3G SIM card adapter.
The SFF MSI MS-9A29 can be mounted to the back of monitors or on a wall. It supports Windows 7 and Windows XP and can output video to two simultaneous displays. It is aimed at kiosks, signage, POS, and industrial machines.
More information can be found on the MS-9A29 product page. However, the company has not yet released pricing or availability (expect it to be on the pricier side though as it is aimed at business/industrial users).

MediaTek, do you even lift?
According to a Taiwan Media Roundtable transcript, discovered by IT World, Qualcomm has no interest, at least at the moment, in developing an octo-core processor. MediaTek, their competitor, recently unveiled an eight core ARM System on a Chip (SoC) which can be fully utilized. Most other mobile SoCs with eight cores function as a fast quad-core and a slower, but more efficient, quad-core processor with the most appropriate chosen for the task.
Anand Chandrasekher of Qualcomm believes it is desperation.
So, I go back to what I said: it's not about cores. When you can't engineer a product that meets the consumers' expectations, maybe that’s when you resort to simply throwing cores together. That is the equivalent of throwing spaghetti against the wall and seeing what sticks. That's a dumb way to do it and I think our engineers aren't dumb.
The moderator, clearly amused by the reaction, requested a firm clarification that Qualcomm will not launch an octo-core product. A firm, but not clear, response was given, "We don't do dumb things". Of course they would not commit to swearing off eight cores for all eternity, at some point they may find core count to be their bottleneck, but that is not the case for the moment. They will also not discuss whether bumping the clock rate is the best option or whether they should focus on graphics performance. He is just assured that they are focused on the best experience for whatever scenario each product is designed to solve.
And he is assured that Intel, his former employer, still cannot catch them. As we have discussed in the past: Intel is a company that will spend tens of billions of dollars, year over year, to out-research you if they genuinely want to play in your market. Even with his experience at Intel, he continues to take them lightly.
We don't see any impact from any of Intel's claims on current or future products. I think the results from empirical testers on our products that are currently shipping in the marketplace is very clear, and across a range of reviewers from Anandtech to Engadget, Qualcomm Snapdragon devices are winning both on experience as well as battery life. What our competitors are claiming are empty promises and is not having an impact on us.
Qualcomm has a definite lead, at the moment, and may very well keep ahead through Bay Trail. AMD, too, kept a lead throughout the entire Athlon 64 generation and believed they could beat anything Intel could develop. They were complacent, much as Qualcomm sounds currently, and when Intel caught up AMD could not float above the sheer volume of money trying to drown them.
Then again, even if you are complacent, you may still be the best. Maybe Intel will never get a Conroe moment against ARM.

Tagged: SFF, open source hardware, open source, minnowboard, Intel, embedded system, atom
The Intel Open Source Technology Group along with CircuitCo recently launched a new small form factor bare-bones system based on open source hardware and running open source software. The Minnowboard includes a 4.2” x 4.2” motherboard, passively-cooled processor, rich IO, UEFI BIOS, and the Angstrom Linux operating system.
The Minnowboard is powered by a single core Intel Atom E640 processor clocked at 1GHz. It is a 32-bit CPU with HyperThreading and VT-x virtualization support. Other hardware includes an integrated Intel GMA 600 GPU, 1GB of DDR2 memory, and 4MB of flash memory used for motherboard firmware. Storage can be added by plugging a SSD or HDD into the single SATA II 3Gbps port.
The Minnowboard has following IO options:
- 1 x micro SD
- 1 x SATA II 3Gbps
- 2 x USB 2.0 ports
- 1 x micro USB
- 1 x mini USB (serial connection)
- 1 x RJ45 jack (Gigabit Ethernet)
- 2 x 3.5mm audio jacks (line in and line out)
- 1 x HDMI
The Minnowboard also has a GPIO header with 8 buffered GPIO pins, 2 GPIO LEDs, and 4 GPIO switches. As such, the system can be expanded by adding extra open source modules called “Lures.” The board is aimed at developers and embedded system manufacturers. The Minnowboard can be used as the bare system or can be integrated into a case or larger device.
The Minnowboard costs $199 and is available for purchase now from Digi-Key, Farnell (UK), Mouser, and Newark.
Obviously, the Minnowboard is nowhere near as cheap as the $35 Raspberry Pi, but it is running x86 hardware which may make it worth it to some users.
If you are interested, you can learn more about the hardware and get involved with the Minnowboard project over at Minnowboard.org.

Another BigFoot sighting...
PCWorld compared an Intel Centrino Advanced-N 6230 to a Qualcomm Killer Wireless-N 1202 using two distinct benchmarks. The first of the tests, a ping and jitter assessment written by Qualcomm, claimed a significant win (2ms vs Intel's 4-8ms) for Killer between laptop and router. The second test measured bandwidth where Qualcomm matched or sometimes doubled Intel's performance except in close range 5GHz scenarios; Intel won, in those cases, by about a factor of two.
Of course, a difference of 2-to-6ms is low for online games. I would imagine those who are genuinely concerned about latency, especially during a LAN Party, would not settle for any form of wireless solution much less plan ahead for it. That could be just my perspective, however; I almost never consider Wi-Fi adapters because I will immediately hunt for an Ethernet jack.
That said, Qualcomm is apparently selling these adapters for prices very comparable to Intel. According to these benchmarks, grains of salt added to taste, Killer would not be a downgrade for a gaming device and should be considered if presented to you. The only time it clearly lost is high speed data transfers at 5GHz less than 10 feet away.
Seriously, Ethernet, keep one in your laptop bag. Magic.
If curious about a purchase, check out the benchmarks (or just skip 802.11n and look for 802.11ac or .11ad equipment); if curious for entertainment, check out Ryan's review of the original, wired, Killer NIC.

Tagged: lga 2011, Ivy Bridge-E, Intel
Intel’s Ivy Bridge-E processors are on their way to enthusiasts and should be available as soon as September 4th according to TechPowerUp. The new HEDT parts are compatible with LGA 2011 motherboards and the CPUs bring performance and power efficiency increases to the enthusiast platform.
The Ivy Bridge-E parts start at $310 and will be price competitive with the existing Sandy Bridge-E and high end Haswell parts. The Core i7-4820K is the lowest-end Ivy Bridge-E processor. This quad core part has base and turbo clockspeeds of 3.7 GHz and 3.9 GHz respectively, 10MB of L3 cache, 48 PCI-E 3.0 lanes, and a quad channel memory controller. It will cost $310.
Beyond that, the Core i7-4930K is the lowest-end six core IVB-E processor. It has six cores clocked at 3.4 GHz base and 3.9 GHz turbo, 12MB L3 cache, 48 PCI-E 3.0 lanes, and a quad channel memory controller. This part will cost $555.
Finally, the top end Core i7-4960X Extreme Edition is a six core CPU clocked at 3.6 GHz base and 4.0 Ghz turbo with 15MB of L3 cache, 48 PCI-E 3.0 lanes, and a quad channel memory controller. This Ivy Bridge-E HEDT CPU will cost $990.
Compared to the existing Sandy Bridge-E chips, IVB-E is actualy coming out of the gate with lower initial MSRPs. Further, the i7-4820K is actually about $30 cheaper than the Core i7-4770K “Haswell” CPU. The six core i7-4930K may be more enticing to those comparing the enthusiast LGA 2011 platform and the LGA 1150 platform, however. The six core Ivy Bride-E part is about $215 more expensive than the $340 four core Haswell i7-4770K which may be a small enough gap that enthusiasts are willing to make the jump for the extra two cores. Granted, Haswell is a bit faster in some respects than IVB-E (according to leaked benchmarks), but the extra two cores gives it a healthy multi-threaded performance advantage.

Intel envisions a sea change in the server room, with servers, SANs and racks of switches which all have been controlled separately becoming much more software based as the ability to virtualize hardware becomes more prevalent. This is not to imply that the hardware will disappear and that Intel will go the way of IBM and get out of the chip business as neither are true; instead Intel is moving forward on the belief that the optimization of your virtualization software will be more important than specific hardware optimizations. While it is great to have tiered storage with expensive SSDs, solid SAS drives and other longer term and lower availability all working together there is little benefit if the software which allocates your data to those media doesn't do so properly.
In this new server room the SoC could be king, modular designs which offer scalable processing power to any and all tasks which is something that ARM cut its teeth on and is now scaling up their power to become a major player in server room design. Intel is coming at this market segment from the other direction as it has to trim power down on its chips without crippling them like we saw in the first 45nm Atom chips. To that end they are working on the new Silvermont architecture, the 22nm Avoton and Rangley which will be mature 64bit chips, something that ARM is still in early days with. Check out more info on these two chips and their successors, along with a teaser on Broadwell at The Tech Report.
"Last week, Intel hosted an event for press and analysts where it provided some updates on the state of its data center business. Then it proceeded to confound our expectations by demonstrating how it's gearing up for a protracted fight with ARM."

DigiTimes wrangled up some information on part of the upcoming IDF, a teaser on Intel's expected mobile announcements. Intel powered smartphones developed with Lenovo, ZTE, Acer and Asustek Computer will be on display though it is unclear what processor will be inside, it is unlikely to be the 22nm Merrifield as that is still months away but you never know with Intel. Wearable computing, voice recognition and gesture controllers will also be making an appearance so Ryan should have an interesting trip again this year.
"Intel is set to host Intel Developer Forum (IDF) 2013 in San Francisco, the US from September 10-12 to further discuss its 2-in-1 device plans as well as its latest progress in Android smartphone and tablet development, according to sources from the upstream supply chain."

Intel has spent the day announcing new products for the server room, from new Atoms to Xeons. Atom will bear the names of Avoton and Rangeley, Avoton will deal with microservers where power and heat are a major concern while Rangeley will appear in network devices and possibly mobile communication devices. In the case of Avoton it will be replacing a chip that has not yet been released, the 32nm Atom S1200 lineup is due out in the near future and will fill a new niche for Intel that Centerton failed to fill. The Register talks a bit more indepth here.
Slightly more powerful will be new Broadwell and Denverton Xeons, the first SoC server chips from Intel which will be manufactured on the 14nm process. We heard much less about these upcoming chips, due for 2014 but you can read what is available at The Inquirer.
"SAN FRANCISCO: CHIPMAKER Intel has revealed more details about its server processor roadmap, including its upcoming Atom chips codenamed Avoton and Rangeley and new 14nm Xeon and Atom parts codenamed Broadwell and Denverton, respectively."

Intel recently posted a Product Change Notification (PCN, number 112432-00) regarding one of its first NUC bare-bones systems, model number BOXDCCP847DYE. The PCN seeks to address the overheating issues that several hardware review sites encountered when performing large file copies across the network using the built-in Wi-Fi card. Intel has reportedly found a solution by adding a 9.5mm thermal pad to the underside of the top cover. The thermal pad will make contact with the mSATA SSD and facilitate heat transfer from the drive into the metal chassis.
The overheating problems spotted by PC Perspective (in our review) and other tech sites lead to system freezes and restarts. When transferring large amounts of data across the network, the built-in mPCI-E Wi-Fi card would heat up, and because the SSD is mounted just above the Wi-Fi card, the system would lock up or crash when the SSD overheated. Thus, Intel’s workaround is to improve the cooling of the SSD such that it (hopefully) will no longer overheat and users will not have to resort to buying a USB Wi-Fi dongle or running an Ethernet cable to the switch.
According to the PCN, the solution works and system retailers should expect shipments of the BOXDCCP847DYE with upgraded cover to arrive as early as August 1st. Notably, Intel is planning to ship out all pre-modification inventory before moving onto shipping updated bare-bones systems. It may be some time before consumers can be sure they are getting the updated model. In the meantime, users can always opt to use one of the many third party NUC cases that take full advantage of passive cooling techniques.
