OCaholic has spotted an interesting entry in the CPU-Z database. According to the site, an overclocker by the handle of “rtiueuiurei” has allegedly managed to push an engineering sample of Intel’s upcoming Haswell Core i7-4770K processor past 7GHz.

Intel Core i7-4770K Overclocked Beyond 7GHz.jpg

If the CPU-Z entry is accurate, the overclocker used a BCLK speed of 91.01 and a multiplier of 77 to achieve a CPU clockspeed of 7012.65MHz. The chip was overclocked on a Z87 motherboard along with a single 2GB G.Skill DDR3 RAM module. Even more surprising than the 7GHz clockspeed is the voltage that the overclocker used to get there: an astounding 2.56V according to CPU-Z.

From the information Intel provided at IDF Beijing, the new 22nm Haswell processors feature an integrated voltage regulator (IVR), and the CPU portion of the chip’s voltage is controlled by the Vccin value. Intel recommends a range of 1.8V to 2.3V for this value, with a maximum of 3V and a default of 1.8V. Therefore, the CPU-Z-reported number may actually be correct. On the other hand, it may also just be a bug in the software due to the unreleased-nature of the Haswell chip.

Voltage questions aside, the frequency alone makes for an impressive overclock, and it seems that the upcoming chips will have decent overclocking potential!

Intel gets a bad wrap on the graphics front.  Much of it is warranted but a lot of it is really just poor marketing about the technologies and features they implement and improve on.  When AMD or NVIDIA update a driver or fix a bug or bring a new gaming feature to the table, they are sure that every single PC hardware based website knows about and thus, that as many PC gamers as possible know about it.  The same cannot be said about Intel though - they are much more understated when it comes to trumpeting their own horn.  Maybe that's because they are afraid of being called out on some aspects or that they have a little bit of performance envy compared to the discrete options on the market. 

Today might be the start of something new from the company though - a bigger focus on the graphics technology in Intel processors.  More than a month before the official unveiling of the Haswell processors publicly, Intel is opening up about SOME of the changes coming to the Haswell-based graphics products. 

We first learned about the changes to Intel's Haswell graphics architecture way back in September of 2012 at the Intel Developer Forum.  It was revealed then that the GT3 design would essentially double theoretical output over the currently existing GT2 design found in Ivy Bridge.  GT2 will continue to exist (though slightly updated) on Haswell and only some versions of Haswell will actually see updates to the higher-performing GT3 options.

In 2009 Intel announced a drive to increase graphics performance generation to generation at an exceptional level.  Not long after they released the Sandy Bridge CPU and the most significant performance increase in processor graphics ever.  Ivy Bridge followed after with a nice increase in graphics capability but not nearly as dramatic as the SNB jump.  Now, according to this graphic, the graphics capability of Haswell will be as much as 75x better than the chipset-based graphics from 2006.  The real question is what variants of Haswell will have that performance level...

02.jpg

I should note right away that even though we are showing you general performance data on graphics, we still don't have all the details on what SKUs will have what features on the mobile and desktop lineups.  Intel appears to be trying to give us as much information as possible without really giving us any information.

Possible power supply issues for Intel Haswell CPUs

Subject: Cases and Cooling, Processors | May 1, 2013 - 12:07 PM |
Tagged: power supply, Intel, idle, haswell, c7, c6

I came across an interesting news story posted by The Tech Report this morning that dives into the possibility of problems with Intel's upcoming Haswell processors and currently available power supplies.  Apparently, the new C6 and C7 idle power states that give the new Haswell architecture benefits for low power scenarios place a requirement of receiving a 0.05 amps load on the 12V2 rail.  (That's just 50 milliamps!)  Without that capability, the system can exhibit unstable behavior and a quick look at the power supply selector on Intel's own website is only listing a couple dozen that support the feature. 

haswellpsu.jpg

This table from VR-Zone, the source of the information initially, shows the difference between the requirements for 3rd (Ivy Bridge) and 4th generation (Haswell) processors.  The shift is an order of magnitude and is quite a dramatic change for PSU vendors.  Users of Corsair power supplies will be glad to know that among those listed with support on the Intel website linked above were mostly Corsair units!

A potential side effect of this problem might be that motherboard vendors simply disable those sleep states by default.  I don't imagine that will be a problem for PC builders anyway since most desktop users aren't really worried about the extremely small differences in power consumption they offer.  For mobile users and upcoming Haswell notebook designs the increase in battery life is crucial though and Intel has surely been monitoring those power supplies closely. 

I asked our in-house power supply guru, Lee Garbutt, who is responsible for all of the awesome power supply reviews on pcper.com, what he thought about this issue.  He thinks the reason more power supplies don't support it already is for power efficiency concerns:

Most all PSUs have traditionally required "some load" on the various outputs to attain good voltage regulation and/or not shut down. Not very many PSUs are designed yet to operate with no load, especially on the critical +12V output. One of the reasons for this is efficiency. Its harder to design a PSU to operate correctly with a very low load AND to deliver high efficiency. It would be easy just to add some bleed resistance across the DC outputs to always have a minimal load to keep voltage regulation under control but then that lowers efficiency.

Intel Talks Haswell Overclocking at IDF Beijing

Subject: Processors | April 17, 2013 - 06:48 PM |
Tagged: overclocking, intel ivr, intel hd graphics, Intel, haswell, cpu

During the Intel Developer Forum in Beijing, China the X86 chip giant revealed details about how overclocking will work on its upcoming Haswell processors. Enthusiasts will be pleased to know that the new chips do not appear to be any more restrictive than the existing Ivy Bridge processors as far as overclocking. Intel has even opened up the overclocking capabilities slightly by allowing additional BCLK tiers without putting aspects such as the PCI-E bus out of spec.

The new Haswell chips have an integrated voltage regulator, which allows programmable voltage to both the CPU, Memory, and GPU portions of the chip. As far as overclocking the CPU itself, Intel has opened up the Turbo Boost and is allowing enthusiasts to set an overclocked Turbo Boost clockspeed. Additionally, Intel is specifying available BCLK values of 100, 125, and 167MHz without putting other systems out of spec (they use different ratios to counterbalance the increased BCLK, which is important for keeping the PCI-E bus within ~100Mhz). The chips will also feature unlocked core ratios all the way up to 80 in 100MHz increments. That would allow enthusiasts with a cherry-picked chip and outrageous cooling to clock the chip up to 8GHz without overclocking the BCLK value (though no chip is likely to reach that clockspeed, especially for everyday usage!).

Remember that the CPU clockspeed is determined by the BCLK value times a pre-set multiplier. Unlocked processors will allow enthusiasts to adjust the multiplier up or down as they please, while non-K edition chips will likely only permit lower multipliers with higher-than-default multipliers locked out. Further, Intel will allow the adventurous to overclock the BLCK value above the pre-defined 100, 125, and 167MHz options, but the chip maker expects most chips will max out at anywhere between five-to-seven percent higher than normal. PC Perspective’s Morry Teitelman speculates that slightly higher BCLK overclocks may be possible if you have a good chip and adequate cooling, however.

Similar to current-generation Ivy Bridge (and Sandy Bridge before that) processors, Intel will pack Haswell processors with its own HD Graphics pGPU. The new HD Graphics will be unlocked and the graphics ratio will be able to scale up to a maximum of 60 in 50MHz steps for a potential maximum of 3GHz. The new processor graphics cards will also benefit from Intel’s IVR (programmable voltage) circuitry. The HD Graphics and CPU are fed voltage from the integrated voltage regulator (IVR), and is controlled by adjusting the Vccin value. The default is 1.8V, but it supports a recommended range of 1.8V to 2.3V with a maximum of 3V.

Finally, Intel is opening up the memory controller to further overclocking. Intel will allow enthusiasts to overclock the memory in either 200MHz or 266MHz increments, which allows for a maximum of either 2,000MHz or 2,666MHz respectively. The default voltage will depend on the particular RAM DIMMs you use, but can be controlled via the Vddq IVR setting.

It remains to be seen how Intel will lock down the various processor SKUs, especially the non-K edition chips, but at least now we have an idea of how a fully-unlocked Haswell processor will overclock. On a positive note, it is similar to what we have become used to with Ivy Bridge, so similar overclocking strategies for getting the most out of processors should still apply with a bit of tweaking. I’m interested to see how the integration of the voltage regulation hardware will affect overclocking though. Hopefully it will live up to the promises of increased efficiency!

Are you gearing up for a Haswell overhaul of your system, and do you plan to overclock?

IDF: Intel Announces Upcoming Haswell and Ivy Bridge-E Xeon Processors

Subject: General Tech | April 10, 2013 - 01:14 PM |
Tagged: xeon-ex, xeon-ep, xeon, server, Intel, HPC, haswell

Intel officially announced its next-generation Xeon processors at IDF Beijing today. The new lineup includes the Haswell-based Xeon E3 1200 V3 family on the low end, and the Ivy Bridge-EP Xeon E5 and Ivy Bridge-EX Xeon E7 aimed at the mid-range general purpose and high-end HPC markets respectively. Intel did not disclose pricing or details on the new chips (such as core counts, cache, clockspeeds, number of SKUs etc.). However, the x86 chip giant did state that the new chips are coming later this year as well as teasing a few tidbits of information on the new Xeon chips.

The upcoming Xeon E3 processors will be part of the Xeon E3 1200 V3 family. These chips will be based on Haswell and are limited to one socket per board. Thanks to the Haswell architecture, Intel has managed to reduce power consumption by approximately 25% and increase video transcoding performance by about 25%. There will be at least one Xeon E3 1200 V3 series chip with a 13W TDP, for example.

Intel is also releasing a new media software development kit (SDK) for Linux and Windows machines that will provide a common platform for developers. It has allowed Intel to maximize the use of both the CPU and GPU for HD video transcoding as well as increasing the number of simultaneous video transcodes over previous generations. The new Xeon E3 1200 V3 (Haswell) chips will be available sometime before the end of 2013.

Intel Xeon Logo.jpg

The next-generation Xeon E5 chips will be based on the 22nm Ivy Bridge-EP architecture. They will be positioned at general purpose computing in data centers (and possibly high-end workstations), and will be limited to 2 sockets per motherboard. The new Xeon E5 processors will incorporate Intel Secure Key and OS Guard technologies. OS Guard is the evolution of the company's existing Intel Execute Disable Bit security technology. Intel is also including AES-NI (AES-New Instructions), to improve the hardware acceleration of AES encrypt/decrypt operations. These mid-range Xeon chips will be available in Q3 2013.

Finally, the top-end Xeon E7 processors will be based on the 22nm Ivy Bridge-EX architecture. The upcoming processors are intended for high performance server and supercomputing applications where scalability and performance are important. The Ivy Bride-EX chips are compatible with motherboards that will have between 4 and 8 sockets and up to 12TB of RAM per node. Further, Intel has packed these processors with new RAS features, including Resilient System Technology and Resilient Memory Technology. The RAS features ensure stability and data integrity in calculations are maintained. Such features are important in scientific, real-time analytics, cloud computing, and banking applications, where performance and up-time are paramount and any errors could cost a company money. Intel has stated that the new Xeon E7 CPUs will be available in the fourth quarter of this year (Q4'13).

While I was hoping for more details as far as core count, clockspeeds, and pricing, the approximate release to market timeframe for the chips is known. Do you think you will be upgrading to the new Xeon chips later this year, or are your current processors fast enough for your server applications?

More information on the upcoming Xeon chips can be found in this Intel fact sheet (PDF).

Haswell, we have a problem. USB 3.0 woes may lead to delays

Subject: General Tech | April 5, 2013 - 11:06 AM |
Tagged: haswell, Intel, usb 3.0, oops

Hardware.Info has recently had confirmation of the rumours we have heard about Intel's USB 3.0 chipset in Haswell; the problem exists and it will cause delays.  Many readers may find this remeniscent of the issues with the Marvell 88SE9123 SATA controller from back in the days of P55 boards.  This time however the issue has been caught before a single board was sold and while it is upsetting that we will be waiting even longer for Haswell perhaps it is better to get a working product late.  It could be quite annoying to lose all your peripherals every time your machine goes into S3.  Follow the links from their post for more details.

Noctua Offers Free LGA 1150 Haswell Mounting Kit Upgrade for Older Heatsinks

Subject: General Tech | March 19, 2013 - 09:05 PM |
Tagged: noctua, lga 1150, hsf, heatsink, haswell, cpu cooler

Noctua has recently announced that the company is providing free mounting kits to owners of existing coolers to make them compatible with Intel's latest LGA 1150 (Haswell) motherboards. The new NM-i115x mounting kit will allow enthusiasts to recycle their older Noctua coolers with the new platform without issue. The kit includes a new back plate with fixed struts and the necessary connectors (screws, springs, et al) to make alignment and mounting easier than previous setups.

Noctua NM-i115X.jpg

Because the LGA 1150 socket keeps the same mounting hole spacing as the current LGA 1156 and LGA 1155 sockets, many newer Noctua cooler will not need the mounting kit upgrade, and can simply be installed into the Haswell machine as is. In other words, if the heatsink worked with your Lynnfield, Sandy Bridge, or Ivy Bridge-based system, it will work in a Haswell system as well. According to Noctua, the following coolers are already compatible with Haswell:

NH-C14, NH-D14, NH-C12P SE14, NH-L12, NH-L9i, NH-U12P SE2, NH-U9B SE2

If your cooler was released prior to LGA 1156, you will need to grab the NM-i115x mounting kit upgrade by filling out this form. Noctua will make the kit available on its website as well as in retail stores (for a minimal charge, though the company did not provide specific pricing). You will need to provide proof of purchase for your existing cooler by sending Noctua a scan or screenshot of your invoice or receipt.

For more information on the NM-i115x, head over to the Noctua product page.

It is nice to see Noctua standing behind its products like this, even if it only affects a small number of users that will be making the jump for LGA 775/ect to LGA 1150.

      1. I have a different kind of question for you. I have an HIS HD6850 that has been damaged. Six surface mounted capacitors and three resistors have been knocked off the back side of the board and were lost forever. With little to lose I removed one cap, measured the voltage, took a dead geforce 7600 and salvaged caps of approximately the same value to put Humpty back together again. To my astonishment the card works... kinda. It cooperates until I install the driver then becomes very unstable and struggles to go any further than the windows loading screen.
      2. I don't know the capacitance of the original components and cannot find any schematics online for any card ever created. I do not need the card but this has become a bit of a challenge. Any ideas or thoughts on how I might be victorious and declare dominance over this wreckage?
