New Microsoft Surface Laptop Announced with Windows 10 S

Subject: Mobile | May 2, 2017 - 11:33 AM |
Tagged: Windows 10 S, touchscreen, surface laptop, surface, microsoft, Intel, core i7, core i5

Microsoft has announced their new Surface Laptop, which notably leaked just yesterday, but the surprising part was not the hardware at all - however sleek and impressive it might be. Yes, it seems I spoke too soon with the Windows 10 S news, as this consumer (I assume) product is shipping with that new version of the OS which only allows apps to be installed from the Windows Store.

As to the hardware, it is milled from a block of aluminum (as shown in a very Apple-like video) and the heat pipes for the processor are milled into the bottom case to help make this so thin, but the laptop will undoubtedly feel warm to the touch during use (a fact which was mentioned on stage as a positive thing). The palmrest/keyboard is coated in a fabric material called Alcantara, rather than being bare metal and plastic. The combination of warmth (literally) and the fabric surface is supposed to make the new laptop feel very friendly, as the narrative went.

Thankfully (in my opinion, anyway) the bizarre flexible hinge of the prior Surface laptop is gone in favor of a conventional one - and with it the air gap from he previous design. Among the features mentioned for this new Surface were its PixelSense screen, which is the “thinnest LCD touch panel ever in a laptop”, and a very impressive 14.5 hour battery life. The standby power consumption was described as effectively zero, which suggests that a suspend state of some kind is standard to prevent drain when not in use. rather than a low-power sleep.

I will briefly editorialize here to mention the Windows 10 S problem here. That limitation might make sense for education, if Microsoft is providing a suite of apps that make sense for a school, but consumers will undoubtedly want more flexibility from their own devices. This is less consumer-friendly than even the Starter Edition of Windows from the past, which limited the number of running applications but not their provenance.

Intel gives their Atom C2000 a longer half life

Subject: General Tech | April 28, 2017 - 12:40 PM |
Tagged: c2000, atom, Intel, Avoton

Intel have released a new C0 stepping of their Avoton based Atom C2000 series, which have been dying off at an alarming rate thanks to a flaw in the chip's low pin count bus clock outputs.  The chips are found in the Synology DS1815+ series as well as in Cisco routers, Dell servers and a variety of other products; the flaw in the LPC clock bus would cause them to enter a state in which a reboot would be fatal.  Intel has offered a patch for the motherboards of devices using these chips for a while and have now released new versions of these chips which do not suffer from the same problem.  

The Register accumulated a longer list of devices that could be at risk and technical details on the nature of the flaw here.

"Intel finally has reworked its flawed Atom C2000 chips, which have been failing at a greater-than-expected rate for about a year and a half."

Spent all your money on a new CPU and couldn't afford an SSD? Intel Optane Memory is here

Subject: Storage | April 24, 2017 - 05:20 PM |
Tagged: XPoint, srt, rst, Optane Memory, Optane, Intel, hybrid, CrossPoint, cache, 32GB, 16GB

At $44 for 16GB or $77 for a 32GB module Intel's Optane memory will cost you less in total for an M.2 SSD, though a significantly higher price per gigabyte.  The catch is that you need to have a Kaby Lake Core system to be able to utilize Optane, which means you are unlikely to be using a HDD.  Al's test show that Optane will also benefit a system using an SSD, reducing latency noticeably although not as significantly as with a HDD.

The Tech Report tested it differently, by sourcing a brand new desktop system with Kaby Lake Core APU that did not ship with an SSD.  Once installed, the Optane drive enabled the system to outpace an affordable 480GB SSD in some scenarios; very impressive for a HDD.  They also did peek at the difference Optane makes when paired with aforementioned affordable SSD in their full review.

"Intel's Optane Memory tech purports to offer most of the responsiveness of an SSD to systems whose primary storage device is a good old hard drive. We put a 32GB stick of Optane Memory to the test to see whether it lives up to Intel's claims."

Introduction, Specifications, and Requirements

Introduction:

170421-115336a.jpg

Finally! Optane Memory sitting in our lab! Sure, it’s not the mighty P4800X we remotely tested over the past month, but this is right here, sitting on my desk. It’s shipping, too, meaning it could be sitting on your desk (or more importantly, in your PC) in just a matter of days.

Intel-3D-Xpoint.png

The big deal about Optane is that it uses XPoint Memory, which has fast-as-lightning (faster, actually) response times of less than 10 microseconds. Compare this to the fastest modern NAND flash at ~90 microseconds, and the differences are going to add up fast. What’s wonderful about these response times is that they still hold true even when scaling an Optane product all the way down to just one or two dies of storage capacity. When you consider that managing fewer dies means less work for the controller, we can see latencies fall even further in some cases (as we will see later).

Read on for our full review of Optane Memory!

Introduction and Specifications

Introduction

Intel-3D-Xpoint.png

XPoint. Optane. QuantX. We've been hearing these terms thrown around for two years now. A form of 3D stackable non-volatile memory that promised 10x the density of DRAM and 1000x the speed and endurance of NAND. These were bold statements, and over the following months, we would see them misunderstood and misconstrued by many in the industry. These misconceptions were further amplified by some poor demo choices on the part of Intel (fortunately countered by some better choices made by Micron). Fortunately cooler heads prevailed as Jim Handy and other industry analysts helped explain that a 1000x improvement at the die level does not translate to the same improvement at the device level, especially when the first round of devices must comply with what will soon become a legacy method of connecting a persistent storage device to a PC.

Did I just suggest that PCIe 3.0 and the NVMe protocol - developed just for high-speed storage, is already legacy tech? Well, sorta.

ss-142.png

That 'Future NVM' bar at the bottom of that chart there was a 2-year old prototype iteration of what is now Optane. Note that while NVMe was able to shrink down the yellow bar a bit, as you introduce faster and faster storage, the rest of the equation (meaning software, including the OS kernel) starts to have a larger and larger impact on limiting the ultimate speed of the device.

NAND Flash simplified schematic (via Wikipedia)

Before getting into the first retail product to push all of these links in the storage chain to the limit, let's explain how XPoint works and what makes it faster. Taking random writes as an example, NAND Flash (above) must program cells in pages and erase cells in blocks. As modern flash has increased in capacity, the sizes of those pages and blocks have scaled up roughly proportionally. At present day we are at pages >4KB and block sizes in the megabytes. When it comes to randomly writing to an already full section of flash, simply changing the contents of one byte on one page requires the clearing and rewriting of the entire block. The difference between what you wanted to write and what the flash had to rewrite to accomplish that operation is called the write amplification factor. It's something that must be dealt with when it comes to flash memory management, but for XPoint it is a completely different story:

reading_bits_in_crosspoint_array.jpg

XPoint is bit addressible. The 'cross' structure means you can select very small groups of data via Wordlines, with the ultimate selection resolving down to a single bit.

ss-141.png

Since the programmed element effectively acts as a resistor, its output is read directly and quickly. Even better - none of that write amplification nonsense mentioned above applies here at all. There are no pages or blocks. If you want to write a byte, go ahead. Even better is that the bits can be changed regardless of their former state, meaning no erase or clear cycle must take place before writing - you just overwrite directly over what was previously stored. Is that 1000x faster / 1000x more write endurance than NAND thing starting to make more sense now?

Ok, with all of the background out of the way, let's get into the meat of the story. I present the P4800X:

Rumor: Intel Expects Coffee Lake and Basin Falls Early

Subject: Processors | April 19, 2017 - 08:00 PM |
Tagged: skylake-x, ryzen, kaby lake x, Intel, Core, coffee lake, amd

According to DigiTimes, Intel is expecting to release several new processors earlier than they had originally planned. That said, there are two issues with this report. The first point, which should be expected, is that it compares internal dates that were never meant to be public. It is not like Intel has changed their advertised roadmap.

The second problem is that it’s somewhat contradicted by Intel’s earlier, public statements.

Intel-logo.png

Their rumor claims that Intel will push up the launch of Basin Falls, which is Skylake-X, Kaby Lake-X, and X299, by about two months (around June). It also claims that Coffee Lake, which was originally scheduled for January 2018, will be released in August 2017. Both of these moves are being attributed to AMD’s new products.

The potential, somewhat, sort-of contradiction comes from a tweet that Intel made back in February. In it, they said that the 8th generation of Core processors are expected for 2H’17. This time frame doesn’t include January, although it only barely includes August, too. If Intel was always planning on launching Coffee Lake for the “back to school” season, then at least that half of DigiTimes’ story would be completely incorrect. On the other hand, if Intel’s tweet was talking about a sampling / paper launch in December, with volume shipment soon to follow, then DigiTimes would be fairly accurate.

We don’t know unless someone at Intel confirms either-or.

As for Skylake-X and Kaby Lake-X, it would be interesting to see them launch at Computex / E3. Previous rumors (also from DigiTimes) that place it in the Gamescom, which is a huge gaming conference in Cologne. Interestingly, this rumor claims that only the four-, six-, eight-, and ten-core models will arrive at the time, with a twelve-core model waiting until the whole line was supposed to launch.

This omission makes me wonder if, in fact, Intel are rushing the launch, but they realize that they cannot get enough good chips to fill out the top-end SKU. In that case, it would make sense to push the smaller and partially-disabled chips out the door, while banking the big chips that can run all twelve cores at a reasonable voltage for some clock rate.

If so, that would, in fact, speak volumes about AMD’s roadmap (and Intel’s opinion of it).

I knew him; IDF, a fellow of infinite jest, of most excellent fancy

Subject: General Tech | April 17, 2017 - 04:09 PM |
Tagged: Intel, idf

It is not a post-PC world but it is now officially a post-IDF world as Intel announces they are too diverse to host such a PC-centric conference.  It was 20 years ago today that the first IDF was held in Beijing and Intel announced some time ago the cancellation of this years event in China, however until today they had still planned to hold their scheduled event in San Francisco.  The rationale offered is Intel's expansion into FPGAs, Optane storage, IoT devices, wireless communications and other fields pushes them beyond the scope traditionally represented at the IDF.  Why cancellation of the event in preference of broadening the scope is not explained in their announcement.  Ars Technica has related links here.

"While the company earlier said that it would not have a Chinese event, the San Francisco IDF was still being planned, albeit with a "new format," in the early months of 2017. It appears now that this 'new format' is in fact 'non-existence.'"

It has been a while since the last legal battle but Qualcomm may be our next contender

Tagged: sueball, qualcomm, Intel, blackberry, apple

Ah, the old days of Microsoft versus governments, Apple and Samsung, Intel and AMD, SCO and ... well just about everyone; lately there has not been much legal vitriol in the headlines.  This may change as Qualcomm is now involved in several suits which are likely to become high profile.  First up is what may be the driving force behind their need to seek restitution from Apple; they were just ordered to pay Blackberry $815 million after that company was successful in their legal battle to dispute certain royalty payments.  Even a company as large as Qualcomm is going to feel the pain from that.

On to the real upcoming battle royal, featuring Apple and Qualcomm over the iPhone 7.  It seems that Apple has taken offence to Qualcomm's claims that Apple handicapped their chip to ensure it did not out perform the models which contained an Intel chipset.  Qualcomm released a large rebuttal to the lawsuit which Apple launched this January which you can read about at Ars Technica, or follow the link to read the entire document.  This may prove to be the next interesting technological legal battle, stay tuned for more.
