Tagged: sandy bridge, Quick Sync, P-series, Intel, i5-2550K
According to this article over at Anandtech, Intel has rather quietly launched seven new processors based on their Sandy Bridge architecture. The most interesting aspect about the new CPUs is not new features or more performance. Rather, it is the lack of features that caught my attention as three of the new additions will not have a functional graphics core.
The three processors without useable IGPs have a "P" moniker in there names which has been stated by VR-Zone to mean that they do not have a graphics core. On the positive side of things, the processors are a bit cheaper than their counterparts with functional GPUs. Such a SKU would compliment P67 motherboards that would not allow users to use the Quick Sync technology with a discrete card present anyway.
The new processors include three Core i5 Sandy Bridge desktop processors and four mobile Celeron chips. On the desktop side of things, we have the new i5-2550K quad core CPU with 6 MB of cache running at 3.4 GHz and a $225 tray price while the i5 2500K MSRP remains at $216 and runs at 3.30 GHz. VR-Zone further reported that this new "K" model would be unlocked but was also one of the three processors that would not have a functional graphics core. Moving down the performance line, the i5 2450P is a quad core part running at 3.2 GHz for $195 and provides a $10 cheaper alternative to the current multiplier locked i5 2500. Last up is the i5 2450P, which will be the IGP-less alternative to the i5 2400 at $184. This part is also a quad core; however, it is only clocked at 3.1 GHz and will sell for $177.
The new Intel Celeron chips are all mobile parts and include two standard voltage and two ultra low voltage (ULV) processors. The Celeron M B815 is a dual core chip running at 1.6 GHz for $86 and the Celeron M B720 is a single core CPU running at 1.7 GHz for $70. The ULV processors are the Celeron M ULV 867 and ULV 797. The ULV 867 is a dual core part at 1.3 GHz for $134 while the ULV 797 is a single core part running at 1.4 GHz for $107.
Are you still running a P67 motherboard interested in eschewing Intel's Quick Sync in a Z68 board for a bit more stock performance and a cheaper price? I think that these new "P" series chips will be something that OEMs will like though I think enthusiast interest will depend on what kind of overclocking headroom they end up having as they aren't all that much cheaper than their current graphics core packing counterparts.

If you are looking for a quick way to contrast the processors that were released this year then iXBT Labs has a review for you. They've added their CPU/APU reviews for the past year together and compiled some rather lengthy charts which reflect the comparative performance of a few older chips as well as the majority of chips released this year. Both Intel and AMD desktop and server chips are included, mobile users will need to look elsewhere to compare chips designed specifically for laptops. Their benchmarks range from 3D modelling to 3D gaming as well as compression, office suites and raster graphics processing so no matter what purpose you will be putting these chips to you should be able to get an idea what chips to be on the look out for.
Told you it was big, visit iXBT Labs if you want the readable version.
"The year 2011 has ended, so it's high time to sum up the results and see the general picture. If you're looking to upgrade, we hope this will make choosing a processor easier."

Tagged: tuning plan, processors, overvolting, overclocking, cpu
Intel relatively recently started producing unlocked "K" series processors that enabled easy overclocking by way of increasing the multiplier. This is a feature that was traditionally reserved for the thousand dollar Extreme Edition products. AMD then followed suit with its own line of "K" series APUs (despite having FX and Black Edition branding already, but that's another story). Well, it is now Intel's turn to leap frog AMD who has traditionally been the overclocker friendly company. Yesterday Intel launched a new pilot program that overclockers and enthusiasts are sure to enjoy. The new Performance Tuning Protection Plan is a program aimed at users of "K" and "X" (unlocked and extreme edition) processors who are adventurous enough to overclock and overvolt their chips to wrangle the best possible performance from them. While the company has stressed that they still do not officially endorse overclocking or otherwise running their CPUs out of Intel specifications, the Performance Tuning Protection Plan is an additional service that can be added in addition to (though seperate from) the existing warranty wherein Intel will furnish a free replacement processor to any users that (unintentionally) damage their processors as a result of overclocking or increasing the voltage. Read on for more details.
The new Performance Tuning Protection Plan will be offered directly from Intel as well as various resellers and can be purchased for any of Intel's K series, X series, or Socket 2011 processors. Only one plan can be applied per processor, and once the CPU has been replaced with a replacement processor through the plan, the insurance does not "roll over" to the replacement part. This means that a second chance is all you get. If the replacement CPU fails as a result of overclocking or overvolting you're out of luck. The Protection Plan is further an additional expense that will applied in addition to the standard 3 year manufacturer's warranty. It only covers damage caused by running the processor out of spec. After purchasing the processor, users can buy the protection plan for a one time fee, and it will kick in within approximately 30 days of buying the plan. Intel says the delay is caused by the time needed for the various plan supporting databases to sync up and for payment to clear.
Prices vary depending on which processor you want to protect with the plan. The Performance Tuning Protection Plan pricing for currently supported processors is listed in the chart below.
|Processor||Price (USD) per CPU|
|Core i5 2500K||$20|
|Core i7 2600K||$25|
|Core i7 2700K||$25|
|Core i7 3930K||$35|
|Core i7 3960X||$35|
Intel is currently offering the new overclocking insurance for a limited time-- a six month trial run to be more specific. Starting January 18th, the company will begin selling the plan directly to customers on their website as well as through several resellers. Initially these resellers include CyberPower, Canada Computers and Electronics, Scan Computers, and Altech Computers. On February 13th, Intel will add additional resellers to the list. The pilot phase will last for six months; after which the company will "decide whether or not to proceed" with the plan. Obviously there is a slight risk for early adopters that after buying the plan, Intel will discontinue it at the six month mark; however, there is also a solid opportunity to overclock the heck out of the chips and have an official safety net for the next few months at the least. Are you running an unlocked processor, and if so will you be checking out the Tuning Protection Plan?

SemiAccurate has been doing some digging into the hardware that will power the next XBox, perhaps a bit more successfully than Microsoft would like. This builds on the rumours that they had collected in December of 2011 and confirms that the next generation console is only a partial win for AMD. Oban is the code name for the CPU, which is being fabbed by GLOBALFOUNDRIES for the most part and will be a variant model of IBM's Power PC architecture and not an x86 based chip. AMD will provide a Graphics Core Next Southern Islands GPU to provide the graphical power, terrible news for NVIDIA's bottom line over the next several years as they lose out on at least one platform of the coming generation. This will continue to sting as unlike PCs, consoles are not refreshed several times over a year and the current hardware will likely be powering the XBox Next for years to come.
From what SemiAccurate has gathered, Microsoft have ordered a huge run of the chips which will power the console and should guarantee availability in the Spring of 2013 which is the current predicted release date for the console. Considering the low yields from GLOBALFOUNDRIES lately this seems likely a move to ensure that even a large amount of bad silicon will not have a major impact on their ability to provide deep supplies of XBox Next for retailers.
"If you crave more info about the upcoming XBox 720/Next, there is finally some concrete info. The one nice thing about this job is that proud parents like to talk, and that is exactly where this story begins."

Let us take a little break from the CES news with a load of bull -- a download of Bulldozer. If you have an eerie sense of being in this situation before then you may in fact have a bad memory as it did in fact happen and it was only about a month ago. Microsoft released an update in mid-December to optimize their operating systems for AMD Bulldozer technology; that patch disappeared without any listed reason. As of today, we have access to both the patch as well as most of the reason for the delay in the first place.
You know: part of me wants to see a Bulldozer go 100MPH, and another part of me fears greatly.
The first order of business is to explain to those who have an AMD FX series, Opteron 4200 series, and/or an Opteron 6200 series processor how to increase their potential performance: KB 2646060 and KB 2645594 each contain a patch which will optimize Windows to the Bulldozer architecture for most users when both are applied.
It turns out that Microsoft pulled the Bulldozer update last month when discussions with AMD revealed that the patch would not provide the promised performance increases for most users. The problem specifically centers on the Core Parking feature within Windows 7 and Windows Server 2008 R2: after the hotfix in December was applied, Core Parking would still interfere with Bulldozer’s design by attempting to save power and sleep cores that were unused without understanding that Bulldozer cores are not typical cores. With Core Parking disabled for Bulldozer-based CPUs either through this hotfix or by changing your performance profiles to “High Performance” from the often default “Balanced” you would allow Bulldozer to run as it actually desires to run. According to how these bulletins are worded, should you have been on “High Performance” profile back in December before the hotfix was pulled you would have experienced what should only have been available starting today.
These performance increases are not for every application, however. AMD has stated that applications which are more sparsely multithreaded would benefit most from the update.
Workloads that are moderately threaded have the potential for uplift. This could include virtualization, database, or transactional environments that are “bursty” – a mixture of light and heavy transactions, or legacy applications that are by nature not very threaded. The more heavily threaded the application, the less the likely the uplift.
My intuition knowing this as well as the Core Parking issue is that once Windows finally wakes the Bulldozer core, your experience is maximal with the December patch; applications which only temporarily become multithreaded either do not wake the proper portions of the processor or wake the processor in time to be of maximum benefit.
It appears as if the removal of the hotfix last month was simply because AMD believed that while the patch was effective, it would not be correctly applied to the vast majority of customers without a second hotfix and thus give the appearance of little to no real benefits.

Today at CES, the Consumer Electronics Show, we got to see a demonstration by AMD of an AMD powered computer running dual monitors. Only, it was not just a dual monitor pushing desktop computer. In a surprise twist, AMD took the side panel off of the desktop computer to reveal that it was actually a laptop computer using their next generation AMD Trinity APU that was driving the game on one display, and the windows desktop on the other display. Even more, on the laptop screen itself, it was playing a 720p video.
Here you can see the two displays that the Trinity powered laptop was driving with Dirt 3 on the left monitor and the Windows desktop on the right one where a video conversion was happening in the background. AMD did not get into any details regarding the transcode, however.
This is the "desktop" computer case that they opened up to reveal that it was, in fact, a Trinity laptop that was driving all the displays.
A die shot of the upcoming Trinity APU (Accelerated Processing Unit) sitting next to a USB flash drive. Specifications of the Trinity APUs have not yet been released by AMD; however, if this leak holds true the Trinity APUs will have either two or four Piledriver CPU cores and TDP (thermal design power) of 65 W, 100 W, and 125 Watts (depending on particular chip). Clock speeds will further vary between 2.2 and 3.8 GHz at stock speeds (will run a bit faster with Turbo Core 3.0). The GPU aspect will be clocked between 563 MHz and 711 MHz and is based on the VLIW4 technology of the Cayman graphics Cards (69xx). They estimate that it will deliver up to 30% more performance versus current Llano chips and will support all the fancy new X86 instruction sets like AVX and AES-NI. A nice boost and hopefully the real specifications will come close to this (or be even better, of course).
Update: Another interesting bit of information is that AMD will have a low power Trinity APU with a TDP of 17 watts and will supposedly deliver the same level of performance as the current Llano chips (that draw twice the power).
Update: AMD has stated Trinity will deliver a 25% increase in CPU performance and a 50% increase in GPU performance versus current Llano APUs. Stay tuned to PC Perspective for more Trinity info as it develops.

It has been a busy year for Phoronix as not only have they had a lot of hardware to review, also Linux developers have been quite busy this year updating drivers and the base kernel. They decided that the beginning of 2012 was a perfect time to reflect on the effects of these changes, specifically the graphics driver that powers the Intel Core i3-330M. The results are mixed, with one driver version excelling in a single task but lagging in others. On the plus side, the performance never stays consistent which gives hope that there is still room for improvement and the performance has not plateaued.
"Back in December I posted historical Intel Sandy Bridge benchmarks looking at the graphics performance over the course of 2011 that this latest-generation of Intel hardware has been supported under Linux. In this article are some similar Intel OpenGL benchmarks of each quarter going back to the end of 2010, but this time it is for the previous-generation Intel Ironlake hardware."

Tagged: pine trail, netbook, Intel, cedar trail, atom, 32nm
Intel has been pumping out quite a few new processors lately, with new Sandy Bridge-E CPUs, a new Sandy Bridge i7 2700K processor coming out, and now a new line of Atom CPUs sneaking in the news right before the new year! Not to mention, they are also working on Ivy Bridge.
The new Atom CPUs are of the Cedar Trail variety and succeed the older Pine Trail-M Atom processors. Currently, there are three Cedar Trail chips that will be available as soon as January in OEM systems including the N2600, N2800, and D2700 CPUs. Further, the new chips are 32nm and have a 22x22mm package size. These little chips are destined to power netbooks, tablets, embedded devices (think medical devices, ruggedized tablets, machinery). Yes, Intel still believes in netbooks, and feels as though emerging markets will keep the market alive and growing as people want for cheap computers that are able to get them on the web. While the netbook is losing popularity in the US, Intel expects the South American, Eastern European, and African markets to see great interest in the netbook platform. Their netbook plans involve three price tiers with accompanying use cases including netbooks at $200 with minimal features and a price to match that enables people to access the web all the way to $400+ netbooks with lots of features that would fill out the market up to where the Ultrabook territory begins at around $900.
The new Cedar Trail processors improve upon the previous gen Atom chips by quite a bit, according to Intel. The graphics aspect in particular has been improved such that 1080p HD Youtube and HD Netflix streams are playable at at least 24 FPS. Something that early netbooks using Intel's integrated graphics will never be able to do. Intel further estimates a 50% lower TDP and a 28% processor performance increase over the Pine Trail chips. Further, the new Cedar Trail chips have more cache at 2 x 512 L2 cache(s), higher clockspeeds, lower TDP, higher C-State (C6 vs C4E)/lower power usage in sleep mode, a 200MHz higher clocked graphics card (400MHz vs 200 MHz), and increased memory speeds (DDR3 800 and 1066 vs DDR3-667). The fastest Nxx chip, the N2800 manages a .2GHz clock speed increase while also knocking off 2 watts from the TDP versus the previous top N570.
Needless to say, Cedar Trail is looking very good, on paper at least. The individual chip specifications are listed below.
|CPU Clock Speed||Graphics Clock Speed||TDP|
|N2600||1.60 GHz||400 MHz||3.5 W|
|N2800||1.86 GHz||640 MHz||6.5 W|
|D2700||2.10 GHz||640 MHz||10 W|
What are your thoughts on the new Cedar Trail chips, do you think they will provide enough "oomph" to make new netbooks desirable again? Some more information can be found here and straight from Intel here.

Tagged: intel atom, Intel, atom
Intel’s Atom processors were created as a tier below their Celeron product line. Netbooks, then running VIA Nano processors, have started to gain popularity since their introduction in late 2007. Intel’s Atom processors took the place of the VIA parts since that time. In 2009, Intel has stated that they have seen approximately twenty percent of their sales of notebook processors replaced with sales of their cheaper Atom processors. Intel still maintains the Atom processor line, but apparently with new goals in mind.
Up and ATOM!!!
According to Digitimes, the demand for Intel’s Atom processors has declined recently. Intel, in response, decided to market that tier of parts to embedded and server customers for use in network-attached storage devices and very low-end servers. Intel is also rumored to have plans to shrink the process size of Atom in 2013 to 22nm and again shrink process size to 14nm in 2014. The upcoming 32nm Atom processor is expected by the second quarter of 2012.

Tagged: Intel, Medfield, Android, x86, SoC
Intel hopes that 2012 will finally be the year they see mainstream phones with Intel inside. Despite Intel's attempts to tell us otherwise for the past several generations, the upcoming Medfield design is the first truly serious attempt to enter the phone and tablet market currently dominated by the many ARM-based partners of phone manufacturers all over the world. A recent post over at Technology Review discussed the advantages that Medfield offers over previous Intel Atom-based designs with Steve Smith, Intel's VP of Architecture.
First shown at the Intel Developer Forum in San Francisco this past September, a Medfield-based reference design has many believing in what some thought was impossible but what others thought was inevitable: Intel x86 cores in a phone that matters. Why the change from many in the analyst space? Medfield is the first option from Intel that is truly a single-chip solution, removing design space concerns and power consumption issues that previous Atom-architecture solutions were saddled with.
Intel showed Technology Review the Android-based reference phone running Gingerbread.
The phone prototype seen by Technology Review was similar in dimensions to the iPhone 4 but noticeably lighter, probably because the case was made with more plastic and less glass and metal. It was running the version of Google's operating system shipping with most Android phones today, known as Gingerbread; a newer version, Ice Cream Sandwich, was released by Google only about a month ago.
Intel has a lot of experience in the consumer markets though it took a shift inside the company to really put the focus on phones and tablets over netbooks and convertible-notebooks. At the recent showing not only did they have the reference design phone but also an iPad-like tablet device running Ice Cream Sandwich, another key to the consumer's dollar. And as you can clearly see in the diagram below, there is a lot of money being made that Intel wants in on. A LOT.
Source: Technology Review, IDC
Intel will also enjoy a process technology advantage over the competition with current Medfield SoCs built on the company's internal 32nm process and the upcoming 22nm technology promises even more power consumption advantanges. ARM designs are built at different foundries including Samsung and TSMC and while they are competitive, no one can keep up with Intel on this front.
Anandtech also had some interesting information to share from an investor conference earlier this month about the power consumption and performance levels of Medfield.
The diagram shows that power consumption on Medfield should be competitive with the current ARM-based SoC leaders in the market today. Areas like 3G standby, basic audio playback and video playback should be accomplished with minimal power draw in order to have battery life extended to at least current expectations. The performance graphs here on Browser Mark and "Graphics" are impressive as well though obviously we have a TON of missing information to really make the graph meaningful. Anand puts it well:
Barring any outright deception however, there seems to be potential in Medfield.
I tend to believe that Intel is too smart to misjudge a product to investors, but remember how impressive the initial performance results of Larrabee were for years?
I am hopeful and excited for Intel's mobility plans in 2012 as other information we have seen looks impressive. Let's see what CES has to offer.

Okay so the pun was a little obvious, but NVIDIA has just announced the specifications and name for the development kit used to develop for their ARM-based GPU computing platform. The development kit will provide a method to build and test applications on a platform similar to what will be found in the Barcelona Supercomputing Centre’s upcoming GPU supercomputer until you are ready to deploy the finished application with real data on the real machine. Such is the life of a development units.
Carma: What goes around, comes around... right Intel?
The development kit is quite modest in its specifications:

Intel was far from demolished when AMD's Bulldozer came to town. Users still clung to hope that Microsoft's Windows 7 was not optimized to take advantage of Bulldozer's multi-core environment. Vindication came sweetly with a knowledge base article and a patch from Microsoft confirming the issue and offering a solution. While they can still feel comfortable knowing they were right, the solution has been pulled from Microsoft's website without any announced reason. Who should we feel sorry for: those who didn't download it yet, or those who did?
To be entirely fair, Microsoft's knowledge base article was quite clear in its instruction to users regarding this hotfix.
A supported hotfix is available from Microsoft. However, this hotfix is intended to correct only the problem that is described in this article. Apply this hotfix only to systems that are experiencing the problem described in this article. This hotfix might receive additional testing. Therefore, if you are not severely affected by this problem, we recommend that you wait for the next software update that contains this hotfix.
Still, AMD users have another reason to be upset as if they needed one. The hotfix will come, and will come in completely stable form; it just looks like today is not that day. If you already received this update and have experienced technical difficulties, the comment form awaits.

When AMD’s Bulldozer processors arrived, they were unable to best Intel’s fastest at most tasks. A number of users held out hope for Bulldozer; however, as it was discovered that Microsoft’s Windows 7 operating system was not optimized to take advantage of the multi-threaded execution scheduling engine. While MS has implemented this optimization in the Windows 8 kernel, the current stable release has been without a fix until recently. The fix in question is available for Windows 7 and Windows Server 2008 R2 and can be downloaded here. It should be noted that service pack 1 is a pre-requisite to this hot-fix.
Conservatively, previous indications suggested such a fix would add a 5 % to 10 % performance boost in multi-threaded applications. That number is based on the estimates from around the web from people comparing benchmarks between Windows 7 and Windows 8 Developer Preview. If you are running a Bulldozer processor in your machine, be sure to apply this update and let us know how performance improves.

NVIDIA lays as the current front-runner for the “Last Year’s Best Decision, This Year” award. You may remember our coverage last June of the AMD Fusion Developer Summit; industry members such as ARM, Microsoft, and of course AMD discussed the potential of utilizing specialized processors and developing on open platforms such as OpenCL and Microsoft’s announced C++ AMP. Do you know what would have been an amazing announcement for AFDS to stomp OpenCL and C++ AMP? That NVIDIA would open up CUDA. Know what announcement missed that bus by a whole half a year? NVIDIA will open up CUDA.
Your platform pooh-pooh? Bear a CUDA.
While I just harassed NVIDIA for their timing, it might not be too late. CUDA is still a powerhouse of a GPGPU platform with substantial software support from absolute mammoth software packages such as Adobe Creative Suite to smaller projects like KGPU. With the open sourcing of the CUDA compiler, NVIDIA is also permitting manufacturers like AMD and even Intel to support CUDA with their GPUs, x86 CPUs, and other processing units. While I am excited at this outcome, I am still somewhat confused about NVIDIA’s timing: they are just a little late to open up and crush the market, and they seem quite abrupt if they originally intended CUDA to survive as a forever-proprietary computing platform.

Our collection of videos comparing the AMD A8-3850 Llano APU to the Sandy Bridge-based Core i3-2105 have been very popular. We thought we would wrap up 2011 with one final video that looks at the integrated graphics solutions on both processors in five of the top games released in 2011. Here is what and how we compared them:
- Batman: Arkham City - 1920x1080 - Low
- Portal 2 - 1920x1080 - Very High
- Battlefield 3 - 1366x768 - Low
- Skyrim - 1920x1080 - Low
- Modern Warfare 3 - 1920x1080 - High
Not to give away the secret but...
Be sure you check out our Video Perspective below!!

Good news for those of you who have been waiting to upgrade in the hopes that Ivy Bridge will be arriving on time. It seems your patience has paid off but you will have to wait a while longer before you can get your hands on Intel's next tick. You can look forward to more PCIe 3.0 lanes, just like those who've jumped onto the new Sandy Bridge E chips and a bump on the GPU portion of the chip. X-bit Labs doesn't have any pricing for the new chips, but they do list all of the models you will be able to buy. One thing you should note are the impressive TDPs, they may not count as low power CPUs but they're certainly lower than other Intel and AMD chips currently on the market.
"Intel Corp. has notified its partners about its decision to introduce of its next-generation code-named Ivy Bridge processors in the second quarter of 2012. Previously the company planned to release the Core i 3000-series central processing units (CPUs) for desktops in March - April timeframe, which left a possibility to unveil the chips in the first quarter."

Although Intel’s latest Sandy Bridge successor, Ivy Bridge, was slated for a January 2012 launch, the situation is now looking more bleak. According to these slides over at BSN, Intel is delaying Ivy Bridge until at least April. While the top end Core i7 3770 Ivy Bridge processor might be available as soon as Q2 2012, it is also the most expensive part, and usually not the one that the majority of enthusiasts are waiting for. Rather, the important processors to watch for are the mid range and overclocker-friendly Core i5 series which will be available in Q3 2012 at the earliest if the current road-map holds true. The i5 3550 part may come out in Q2 2012 along with the top end i7 CPU; however, the majority of i5 processors will be released as soon as Q3 2012.
Further, the budget Core i3 Ivy Bridge parts are in the same boat as the i5 processors, with at least one (possibly) becoming available along with the top end Core i7 part in Q2 2012 and the rest slowly trickling out over the remainder of the year. While it is generally the case that the top end processor(s) are released first, followed by the lower end and less expensive parts, the delay has pushed back a April release for some of the budget parts to a Summer release. Needless to say, it is less than ideal for those consumers eagerly waiting for certain chips to go on sale. Not to mention that for those adventurous few that were willing to pay top dollar for the top end i7 chip this January now have to wait even longer.
The delay is likely due to Intel wanting to get as much money as possible out of the Sandy Bridge platform, and the lackluster launch of AMD’s Bulldozer products. Intel is likely taking the extra time to refine the new chipsets and the PCIe 3.0 support (that is also not technically rated for PCIe 3.0 speeds, sort of (heh)). On the other hand, Bright Side Of News speculates that the delay may be in part due to various retirements throughout the company requiring more development time in addition to needing more time to flesh out the graphics drivers for the GPU portion of Ivy Bridge processors.
Were you hoping for an Ivy Bridge upgrade early next year? Because of the further delays, will you spring for a top end Sandy Bridge system or wait it out for Ivy Bridge despite the money burning a hole in your pocket? As someone that is still rocking a 1156 system, I was hoping to skip Sandy Bridge and go for Ivy Bridge (I seem to love near-end-to-life sockets); however, with the delays I’m not sure what I’ll be doing now.

This year saw the 40th anniversary of (the availability of) the world’s first microprocessor- the Intel 4004 processor- and Intel is as strong as ever. On the supercomputing and HPC (High Performance Computing) front, Intel processors are powering the majority of the Top 500 supercomputers, and at this years supercomputing conference (SC11) the company talked about their current and future high performance silicon. Mainly, Intel talked about its new Intel Xeon E5 family of processors and the new Many Integrated Cores Knights Corner Larrabee successor.
The Intel Xeon E5 is available now.
The new Xeon chips are launching now and should be widely available within the first half of 2012. Several (lucky) supercomputing centers have already gotten their hands on the new chips and are now powering 10 systems on the Top 500 list where the 20,000 Xeon E5 CPUs are delivering a combined 3.4 Petaflops.
According to benchmarks, Intel is expecting a respectable 70% performance increase on HPC workloads versus the previous generation Xeon 5600 CPUs. Further Intel stated that the new E5 silicon is capable of as much as a 2x increase in raw FLOPS performance, according to Linpack benchmarks.
Intel is reporting that demand for the initial production run chips is “approximately 20 times greater than previous generation processors.” Rajeeb Hazra, the General Manager of Technical Computing of Intel’s Datacenenter and Connected Systems Group, stated that “customer acceptance of the Intel Xeon E5 processor has exceeded our expectations and is driving the fastest debut on the TOP 500 list of any processor in Intel’s history.” The company further reiterated several supercomputers that are set to go online son and will be powered by the new E5 CPUs including the 10 Petaflops Stampede computer at the Texas Advanced Computing Center and the 1 Petaflops Pleiades expansion for NASA.
While Intel processors are powering the majority of the world’s fastest supercomputers, graphics card hardware and GPGPU software has started to make its way into quite a few supercomputers as powerful companion processors that can greatly outperform a similar number of traditional CPUs (assuming the software can take advantage of the GPU hardware of course). In response to this, Intel has been working on it’s own MIC (Many Integrated Core) solution for a few years now. Starting with Larrabee, then Knights Ferry, and now Knights Corner, Intel has been working on silicon that using numerous small processing cores that can use the X86 instruction set to power highly parallel applications. Examples given by Intel as useful applications for their Many Integrated Core hardware includes weather modeling, tomography, and protein folding.
Knights Corner is the company’s latest iteration of MIC hardware, and is the first hardware that is commercially available. Knights Corner is capable of delivering more than 1 Teraflops of double precision floating point performance. Hazra stated that “having this performance now in a single chip based on Intel MIC architecture is a milestone that will once again be etched into HPC history” much like Intel’s first Teraflop supercomputer that utilized 9,680 Pentium Pro CPUs in 1997.
What’s interesting about Knights Corner lies in the ability of the hardware to run existing applications without porting to alternative programing languages like Nvidia’s CUDA or AMD’s Stream GPU languages. That is not to say that the hardware itself is not interesting, however. Knights Corner will be produced using Intel’s Tri-Gate transistors on a 22nm manufacturing process, and will feature “more than 50 cores.” Unlike current GPGPU solutions, the Knights Corner hardware is fully accessible and can be programmed as if the card is it’s own HPC node running a Linux based operating system.
More information on the Knights Corner architecture can be found here. I think it will be interesting to see how well Knights Corner will be adopted for high performance workloads versus graphics cards from Nvidia and AMD, especially now that the industry has already begun adapting GPGPU solutions using such programming technologies like CUDA, and graphics cards are becoming more general purpose (or at least less specialized) in hardware design. Is Intel too late for the (supercomputing market adoption) party, or just in time? What do you think?
