Google to Develop CPUs (For Themselves)?

Amazon, Facebook, and Google are three members of a fairly exclusive club. These three companies order custom server processors from Intel (and other companies). Jason Waxman of Intel was quoted by Wired, "Sometimes OEMs and end customers ask us to put a feature into the silicon and it sort of depends upon how big a deal it is and whether it has to be invisible or proprietary to a customer. We're always happy to, if we can find a way to get it into the silicon".

Now, it would seem, that Google is interested in developing their own server processors based on architecture licensed from ARM. This could be a big deal for Intel as Bloomberg believes Google accounts for a whole 4.3% of the chip giant's revenue.

Ouch.

Of course this probably does not mean Google will spring up a fabrication lab somewhere. That would just be nutty. It is still unclear whether they will cut in ARM design houses, such as AMD or Qualcomm, or whether they will take ARM's design and run straight to TSMC, GlobalFoundries, or IBM with it.

I am sure there would be many takers for some sizable fraction of 4.3% of Intel's revenue.

Intel Broadwell to Reach 3.5W and Other Details!

Subject: General Tech, Processors, Mobile | December 14, 2013 - 04:07 AM |
Tagged: Intel, Broadwell

This leak is from China DIY and, thus, machine-translated into English from Chinese. They claim that Broadwell is coming in the second half of 2014 and will be introduced in three four series:

  • H will be the high performance offerings
  • U and Y have very low power consumption
  • M will fit mainstream performance

The high performance offerings will have up to four CPU cores, 6MB of L3 cache, support for up to 32GB of memory, and thermal rating of 47W. The leak claims that some will be configurable down to 37W which is pretty clearly its "SDP" rating. The problem, of course, is whether 47W is its actual TDP or, rather, another SDP rating. Who knows.

The H series is said to be available in either one or two chips.  Both a separate PCH and CPU version will exist as well as a single-chip solution that integrates the PCH on-die.

There is basically nothing said about the M series beyond acknowledging its existence.

The U and Y series will be up to dual-core with 4MB L3 cache. The U series will have a thermal rating of 15W to 28W. The Y series will be substantially lower at 4.5W configurable down to 3.5W. No clue about which of these numbers are TDPs and which are SDPs. You can compare this earlier reports that Haswell will reach as low as 4.5W SDP.

Hopefully we will learn more about these soon and, perhaps, get a functional timeline of Intel releases. Seriously, I think I need to sit down and draw a flowchart some day.

VR-Zone Has, Well, A Haswell-E First Look

Subject: General Tech | December 14, 2013 - 02:01 AM |
Tagged: Intel, Haswell-E

Here's the short version: X99 chipset, quad-channel DDR4 (2133 MHz), 6 or 8 cores with Hyper-Threading, up to 3 GHz, up to 140W TDP.

Haswell-E, the replacement for recently launched Ivy Bridge-E, will hit in Q3 2014. VR-Zone China has already got their hands on an engineering sample but has yet to do any form of benchmarking. I went enthusiast and all I got is this lousy picture.

Well, they also got the slide embedded above. Apart from the specifications that were highlighted above, the slide also claims that both the X and K series will be unlocked for overclockers. Especially given how resilient modern processors are, it makes sense to allow all enthusiast-branded parts to be pushed over stock settings.

Of course Haswell-E should also bring the long-awaited boost to single-threaded performance without compromising on the core count. It is expected to launch Q3 2014.

A Few More Haswell Refresh (2014) Details

Subject: General Tech, Processors | December 13, 2013 - 08:49 PM |
Tagged: Intel, haswell

Intel will begin to refresh their Haswell line of processors, according to VR-Zone, starting in Q2 and continue into Q3. This will be accompanied by their 9-series of motherboard chipsets. The Intel Core i7-4770 and Core i7-4771 will be replaced, not just surpassed, by the Core i7-4790. That said, the only difference is a 100MHz bump to both the base and turbo CPU frequencies.

The K-series processors will come in Q3 and are said to be based on Haswell-E with DDR4 memory. I find this quite confusing because of previous reports that Broadwell-K would appear at roughly the same time. I am unsure what this means for Broadwell-K and I am definitely unsure why some Haswell-E components would be considered part of the Haswell refresh instead of the Haswell-E launch.

My gut instinct believes that VR-Zone is simply confused or that Microsoft and Google Translate are both terrible at understanding this article.

The 25W, four core Xeon E3 1230Lv3

Subject: Processors | December 9, 2013 - 06:23 PM |
Tagged: xeon e3, Intel, haswell, 1230Lv3

Server chips with low power consumption are in style an the Xeon E3-1230Lv3 certainly qualifies at a tiny 25W TDP.  It is a Haswell chip running at a peak speed of 1.8GHz which would be great for a small business or for a home server.  eTeknix compared the performance of this chip to the i7-4770K with a TDP more than three times that of the Xeon which is perhaps a little unfair to the E3 but is a familiar chip to most enthusiasts.  That said the Xeon doesn't fall too far behind in many tests and at $250 it is less expensive to slap into a Z87 motherboard and it will reduce your power bill somewhat.

"Intel’s Xeon E3-1230Lv3 CPU has been a hotly anticipated processor for a wide variety of target audiences – home users, office users, small business users and enterprise users. Today we’ve got an opportunity to put Intel’s enterprise Xeon E3-1230Lv3 CPU to the test in a professional home user or “prosumer” type of environment, by pairing it up with SuperMicro’s server-grade C7Z87-OCE motherboard. The Intel Xeon E3-1230Lv3 is an important CPU because it offers four cores, eight threads, a 1.8GHz base frequency, a 2.8GHz Turbo frequency and 8MB of cache all for a tiny TDP of just 25W."

Leaked Intel Slides Show Possible 2TB SSDs in Q2 2014?

Subject: General Tech, Storage | December 5, 2013 - 10:23 PM |
Tagged: Intel, ssd

Computer storage website, Myce, got a hold of a few slides from Intel's SSD division. The semiconductor giant is expected to have (at least) nine active product lines with new SKUs apparently coexisting with certain older models. Two of the PCIe-based product lines, the P3700 series and the P3500 series, are expected to be available in capacities of up to 2TB. They will apparently be available in 2.5" form factor as well.

Intel has not produced the most mindblowing components over the last 3-4 years but, to my knowledge, they have been effective at wooing the enterprise customers. 2.8 GB/s reads and 1.7 GB/s writes at 450,000 IOPS for reading (150,000 IOPS for writes) seem pretty good, though. Combined with Intel's 5-year warranty and it will probably find its way into a few servers.

myce-intel-ssd-temple-star-2.png

Each of the new products will be fabricated on the 20nm process (the older 910 Series and DC S3700 Series, both from 2012, will remain 25nm). Of course Intel has access to smaller processes at this point but, since these are enterprise products, it makes sense for them to use the more tried and true methods for the time being.

If you are interested in enterprise SSDs, keep an eye out in a couple of quarters. Maybe we will even see some stuff coming out of CES in a month.

Intel Xeon Phi to get Serious Refresh in 2015?

Subject: General Tech, Graphics Cards, Processors | November 28, 2013 - 03:30 AM |
Tagged: Intel, Xeon Phi, gpgpu

Intel was testing the waters with their Xeon Phi co-processor. Based on the architecture designed for the original Pentium processors, it was released in six products ranging from 57 to 61 cores and 6 to 16GB of RAM. This lead to double precision performance of between 1 and 1.2 TFLOPs. It was fabricated using their 22nm tri-gate technology. All of this was under the Knights Corner initiative.

Intel_Xeon_Phi_Family.jpg

In 2015, Intel plans to have Knights Landing ready for consumption. A modified Silvermont architecture will replace the many simple (basically 15 year-old) cores of the previous generation; up to 72 Silvermont-based cores (each with 4 threads) in fact. It will introduce the AVX-512 instruction set. AVX-512 allows applications to vectorize 8 64-bit (double-precision float or long integer) or 16 32-bit (single-precision float or standard integer) values.

In other words, packing a bunch of related problems into a single instruction.

The most interesting part? Two versions will be offered: Add-In Boards (AIBs) and a standalone CPU. It will not require a host CPU, because of its x86 heritage, if your application is entirely suited for an MIC architecture; unlike a Tesla, it is bootable with existing and common OSes. It can also be paired with standard Xeon processors if you would like a few strong threads with the 288 (72 x 4) the Xeon Phi provides.

And, while I doubt Intel would want to cut anyone else in, VR-Zone notes that this opens the door for AIB partners to make non-reference cards and manage some level of customer support. I'll believe a non-Intel branded AIB only when I see it.

People prefer the small chips to the big ones

Tagged: amd, Intel, arm, sales

Chips are hot this year, an increase in sales volume of 27% in Q1, 24% in Q2 and similar growth is expected over the coming year.  Unfortunately for AMD and Intel most of these chips are in mobile devices, a market which neither company has leveraged successfully as of yet; PC chip sales have declined steadily over the previous quarters.  The only good news is for AMD who managed to take a slightly larger share of this shrinking market.  Both companies are going to have to become much more focussed on the ultra low voltage mobile market if they want to remain profitable, which means less development on high end desktop processors.  Grab more market stats over at The Inquirer.

Intel is stacking memory on top of the new Xeons

Subject: General Tech | November 22, 2013 - 12:29 PM |
Tagged: Supercomputing Conference, Intel, SoC, Near Memory, knights landing

Intel spilled more beans about the new Near Memory architecture that will be accompanying their new Xeon release.  The memory will be stacked directly onto the CPU giving much quicker access than you would normally see from DDR3 which has to travel over the motherboard.  They have not disclosed expected speeds, which could be up to what we see in current CPU caches only in much larger sizes.  This is not quite a Xeon SoC but in the presentation The Register heard of Intel's plans to incorporate optical fabrics and switches onto the CPUs as well with size being the only limit.  Perhaps they do have a leg to stand on when they claim the return to power of homogeneous computing.

xeon_plus_memory_stack.jpg

"According to an EE Times report, Intel's Rajeeb Hazra, a VP and general manager of its data centre group, said Intel would customise high-end Xeon processors and Xeon Phi co-processors by closely integrating memory, both by adding memory dies to a processor package and, at a later date, integrating layers of memory dies into the processor along with optical fabrics and switches."

Intel claims Knight's Landing will slay HUMA and bare all CUDA's flaws

Subject: General Tech | November 20, 2013 - 12:53 PM |
Tagged: Xeon Phi, knights landing, Intel, 14nm

Intel has been talking up the Xeon Phi, first of the Knight's Landing chips which shall arrive in the not too distant future.  This new architecture is touted to bring a return of homogeneous systems architecture which will perform parallel processing on its many cores, currently 61 is the number being tossed around, at a level of performance that will exceed the GPU accelerated heterogeneous architecture being pushed by AMD and NVIDIA.  Whether this is true or not remains to be seen but many server builders may prefer the familiar CPU only architecture and as at least some of the Phi's will be available in rack mounted form and not just addin cards they may choose Intel out of habit.   You can also read about Micron's Automata Processor which The Register reports can outperform a 48-chip cluster of Intel Xeon 5650s in certain scenarios.

"From Intel's point of view, today's hottest trend in high-performance computing – GPU acceleration – is just a phase, one that will be superseded by the advent of many-core CPUs, beginning with Chipzilla's next-generation Xeon Phi, codenamed "Knights Landing"."
