ARM Releases Cortex-A72 for Licensing

On February 3rd, ARM announced a slew of new designs, including the Cortex A72.  Few details were shared with us, but what we learned was that it could potentially redefine power and performance in the ARM ecosystem.  Ryan was invited to London to participate in a deep dive of what ARM has done to improve its position against market behemoth Intel in the very competitive mobile space.  Intel has a leg up on process technology with their 14nm Tri-Gate process, but they are continuing to work hard in making their x86 based processors more power efficient, while still maintaining good performance.  There are certain drawbacks to using an ISA that is focused on high performance computing rather than being designed from scratch to provide good performance with excellent energy efficiency.

ARM has been on a pretty good roll with their Cortex A9, A7, A15, A17, A53, and A57 parts over the past several years.  These designs have been utilized in a multitude of products and scenarios, with configurations that have scaled up to 16 cores.  While each iteration has improved upon the previous, ARM is facing the specter of Intel’s latest generation, highly efficient x86 SOCs based on the 2nd gen 14nm Tri-Gate process.  Several things have fallen into place for ARM to help them stay competitive, but we also cannot ignore the experience and design hours that have led to this product.

(Editor's Note: During my time with ARM last week it became very apparent that it is not standing still, not satisfied with its current status. With competition from Intel, Qualcomm and others ramping up over the next 12 months in both mobile and server markets, ARM will more than ever be depedent on the evolution of core design and GPU design to maintain advantages in performance and efficiency. As Josh will go into more detail here, the Cortex-A72 appears to be an incredibly impressive design and all indications and conversations I have had with others, outside of ARM, believe that it will be an incredibly successful product.)

 

Cortex A72: Highest Performance ARM Cortex

ARM has been ubiquitous for mobile applications since it first started selling licenses for their products in the 90s.  They were found everywhere it seemed, but most people wouldn’t recognize the name ARM because these chips were fabricated and sold by licensees under their own names.  Guys like Ti, Qualcomm, Apple, DEC and others all licensed and adopted ARM technology in one form or the other.

arma72_02.jpg

ARM’s importance grew dramatically with the introduction of increased complexity cellphones and smartphones.  They also gained attention through multimedia devices such as the Microsoft Zune.  What was once a fairly niche company with low performance, low power offerings became the 800 pound gorilla in the mobile market.  Billions of chips are sold yearly based on ARM technology.  To stay in that position ARM has worked aggressively on continually providing excellent power characteristics for their parts, but now they are really focusing on overall performance and capabilities to address, not only the smartphone market, but also the higher performance computing and server spaces that they want a significant presence in.

Specifications

When I first was handed the Intel Compute Stick product at CES back in January, my mind began to race with a lot of questions. The first set were centered around the capabilities of the device itself: where could it be used, how much performance could Intel pack into it and just how many users would be interested in a product like this? Another set of questions was much more philosophical in nature: why was Intel going in this direction, does this mean an end for the emphasis on high performance componentry from Intel and who comes up with these darned part numbers?

I have since settled my mind on the issues surrounding Intel’s purpose with the Compute Stick and began to dive into the product itself. On the surface the Intel Compute Stick is a product entering late into a potentially crowded market. We already have devices like the Roku, Google Chromecast, the Apple TV, and even the Amazon Fire TV Stick. All of those devices share some of the targets and goals of the Compute Stick, but the one area where Intel’s product really stands out is flexibility. The Roku has the most pre-built applications and “channels” for a streaming media box. The Chromecast is dirt cheap at just $30 or so. Even Amazon’s Fire TV Stick is clearly the best choice for streaming Amazon’s own multimedia services. But the Intel Compute Stick can do all of those things – in addition to operating as a standalone PC with Windows or Linux. Anything you can do I can do better…

But it’s not a product without a few flaws, most of which revolve around the status of the current operating system designs for TVs and larger displays. Performance obviously isn’t peeling the paint off any walls, as you would expect. But I still think at for $150 with a full copy of Windows 8.1 with Bing, the Intel Compute Stick is going to find more fans that you might have first expected.

When Sebastian reviewed the LIVA X he focused on the performance of the device as an HTPC running Ubuntu ...  before attempting to determine its effectiveness in creating a peanut butter and banana omelette, but that is a different story.

Overclocker's Club took a different tack, examining how it would perform for light gaming duties.  On default settings the LIVA X managed 517 in Sky Diver, 1198 in Cloud Gate, 14200 in Ice Storm, and 9598 in Ice Storm Extreme.  This would make it effective at playing mobile games or even playing through legacy games available through GoG or the Internet Archive; they tested CivV as a more modern title and while playable it wasn't great.  Check out the full review for the other benchmark results.

"The ECS LIVA X surprised me with its small size and completely silent operation. I was able to surf the internet and do work on it very quickly. I enjoyed using it and experienced no problems with browsing the internet, using Office applications, or watching streaming videos on Netflix. Amazon Prime would occasionally lag a little – usually when the HUD would pop up."

Moore's Law Is Fifty Years Old!

Tagged: moores law, Intel

While he was the director of research and development at Fairchild Semiconductor, Gordon E. Moore predicted that the number of components in an integrated circuits would double every year. Later, this time-step would slow to every two years; you can occasionally hear people talk about eighteen months too, but I am not sure who derived that number. In a few years, he would go on to found Intel with Robert Noyce, where they spend tens of billions of dollars annually to keep up with the prophecy.

It works out for the most part, but we have been running into physical issues over the last few years though. One major issue is that, with our process technology dipping into the single- and low double-digit nanometers, we are running out of physical atoms to manipulate. The distance between silicon atoms in a solid at room temperature is about 0.5nm; a 14nm product has features containing about 28 atoms, give or take a few in rounding error.

Josh has a good editorial that discusses this implication with a focus on GPUs.

It has been a good fifty years since the start of Moore's Law. Humanity has been developing plans for how to cope with the eventual end of silicon lithography process shrinks. We will probably transition to smaller atoms and molecules and later consider alternative technologies like photonic crystals, which routes light in the hundreds of terahertz through a series of waveguides that make up an integrated circuit. Another interesting thought: will these technologies fall in line with Moore's Law in some way?

Intel SSD 750 Series PCIe Compatibility Tested

Subject: General Tech, Storage | April 16, 2015 - 10:47 AM |
Tagged: uefi, SSD 750, PCI-E 3.0, NVMe, Intel, ACHI, 750 series

UPDATE: ASUS has pointed us towards a poll they are running to gauge what platforms people are most anxious for NVMe Boot support on. So if you have an ASUS board and are interested in buying an Intel SSD 750 Series, head to their poll to voice your opinion!

Last week, the Intel 750 Series SSD was unveiled the the public as the first consumer SSD to feature the NVMe or Non-Volatile Memory Express interface. NVMe was designed from the ground up for flash storage, and provides significant advantages in latency and potential top transfer rates over the aging AHCI standard. Check out our review of the Intel SSD 750 Series to find out why this is such an important step forward for storage technology.

Even if you aren't necessarily concerned about the merits of a new storage interface, the throughput numbers from the 750 series are hard to ignore. With peak speeds over 2.5GB/s read and 1.5GB/s write, it's hard not to be interested in this new drive.

However, all this new speed doesn't come without a few complications. NVMe is an all-new standard which means it might not be supported on all platforms. Intel themselves only point to official support for Z97 and X99 chipsets. In order to get a better idea of the landscape of NVMe compatibility, I took it amongst myself to start testing the add-in card version of the 750 Series in just about every modern motherboard I could get my hands on at the office.

Leaked: Intel Skylake-S Enthusiast Processor and Chipset Details

Subject: Processors | April 16, 2015 - 02:04 AM |
Tagged: Intel, Skylake, skylake-s, lga1151, 100 series

Some slides have leaked out with information about Intel's forthcoming 6th Generation Core processor, code named Skylake. We have known that Skylake was coming, and coming this year, but there have been a lot of questions about enthusiast parts and what that means for DIY builders. The slides were first seen over at WCCFTech.com and show some interesting new information.

skylakepreso1.jpg

Dubbed Skylake-S, the LGA (socketed) processor will use a new derivative with 1151 pins as well as a new set of chipsets, the Intel 100-series. Skylake is built on the same 14nm process technology used with Broadwell but will feature a new microarchitecture for both the IA cores and the graphics systems. Obviously you can read the slide yourself above, but some of the highlights are worth touching on individually. Skylake will support both DDR3L and DDR4 memory systems with the enthusiast grade parts likely the only ones to attempt to push the newer, faster DDR4 speeds.

Enthusiasts will also be glad to know that there are planned 95 watt quad-core SKUs that will support unlocked features and overclocking capability. Intel lists an "enhanced" BCLK overclocking with the term "full range" which likely means there will no longer be a need for straps to 125 MHz, etc. A 95 watt TDP is higher than the 88 watt limit we saw on Haswell processors so there is a chance we might actually witness usable performance gains if Intel can get the clock speeds up and above where they sit today with current generation parts.

The use of DMI 3.0, the connection between the processor and the chipset, sees the first increase in bandwidth in many generations. Rated at 8 GT/s, twice that of the DMI 2.0 interface used on Haswell, should allow for fewer bottlenecks on storage and external PCIe connections coming from the chipset.

The new Intel 100-series chipsets will come in three variants at launch: the Z170, the H170 and the H110. The one we are most concerned with is the Z170 of course as it will be paired wit the higher end 65 watt and 95 watt enthusiast processors. Based on these specs, Skylake will continue to operate with only 16 lanes of PCI Express 3.0 capable of running at 1 x16, 2 x8 or 1 x8 and 2 x4 connections. With either DDR3L or DDR4 you will have a dual-channel memory system.

skylakepreso4.jpg

For storage, the Z170 still has six SATA 6.0 Gb/s ports, moves to 14 USB ports maximum with 10 of them capable of USB 3.0 speeds and it upgrades Intel RST to support PCIe storage drivers. Of note here is that the Intel chipset does not include USB 3.1 capability so motherboard vendors will continue to need an external controller to integrate it. Without a doubt the 100-series chipsets will be able to support booting and compatibility with the new Intel 750-series PCIe SSDs, the current king of the hill.

As for timing, the roadmap lists the Z170 chipset and the Skylake-S processor as a Q3 2015 release. I would normally expect that to line up with Computex in early June but that doesn't appear to be the case based on other information I am getting.

Checking out PCIe SSDs, both the full sized version and the bite sized ones

Subject: Storage | April 7, 2015 - 06:49 PM |
Tagged: Plextor M6e, XP941, Samsung, DC P3700, Intel, PCIe SSD, M.2

The Tech Report have updated their storage testbed to properly benchmark PCIe SSDs, the M.2 versions as well as ones such as Intel's DC P3700 which takes up a full slot.  They contrast the performance with 10 popular SATA drives to give you an idea of the difference performance a PCI SSD will give you.  The rather expensive DC P3700 dominates almost every test they performed, apart from boot times in Windows 8.1 which are still well under 1 minute.  Read through the review with your own usage patterns in mind, in many cases a SATA SSD is still a great choice for many gamers and are much more affordable.  Then again, if you can afford a $2500 SSD, Intel's offering is definitely king.

"SSDs have been bumping up against the limits of the Serial ATA interface for a while, but they don't have to be stuck behind the 6Gbps link. Native PCIe drives with way more bandwidth have made their way onto the market over the past year. We've tackled a trio of them—Plextor's M6e, Samsung's XP941, and Intel's server-grade DC P3700—with a fresh slate of benchmarks to see how the new breed stacks up against the SATA incumbents."
