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.
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.

It has been a rough year for OCZ as they tried to overcome the problems that they inherited from once CEO Ryan Petersen. The news first broke in February when Wells Fargo announced that they would have OCZ delisted from the stock exchange as they had not submitted an acceptable profit statement since Q1 of 2012. That would have had a drastic effect on the ability of OCZ to do business and would have triggered a shareholder revolt. The new company head, Ralph Schmitt, managed to stave off the Feb 28th deadline with the help of Crowe Horwath LLP's auditors and received an extension on the SEC deadline. As long as OCZ could produce an accurate accounting of 2012 and Q1 of 2013 by April 8th they would not be delisted. Unfortunately the corrected bookkeeping revealed a serious problem with OCZ's sales model. The higher their raw revenues climbed during 2013 the more their net loss increased, with sales incentives, poor chip supplies and other costs contributed to a seemingly unsustainable business model.
Today the sad announcement of the coming demise of OCZ became official, at 9AM EST trading of OCZ stock was suspended as they announced their impending bankruptcy. The trading resumed just a short time ago, at 2:30PM and as you can see the news is bleak for shareholders.
The stock price declined by 67% since the beginning of the year until this announcement and is currently plummeting even more. According to Barrons and other sources, Toshiba has made an offer to purchase OCZ's assets, the "“material terms have been agreed to,” though there are a number of conditions that have to be satisfied, such as retention of employees." Until this deal is finalized we will not know the fate of OCZ and their product lines or warranty support and it could be quite some time before the specifics are agreed upon and announced to consumers. It is a sad day for enthusiasts who have enjoyed the great performance and low prices that OCZ's SSDs lines offered.
UPDATE : “With the recent news OCZ wants to reassure all our valued customers that the Company is honoring all product warranties. If any customers require support they are encouraged to contact our customer support and forum support teams who will be more than happy to assist.”

[H]ard|OCP found something that Win8.1 can do better than Win7, especially now that the mouse issue is not nearly as pervasive. As it turns out the current non-Mantle version of Battlefield 4 performs between 3-6% faster when run on a Win8 machine. While that finding does not imply a huge performance difference they also reported that the video was much smoother when run under Win8 with none of the choppiness that was present under Win7. Think of the frame pacing examples Ryan has provided as a good demonstration of what they are referring to, though the cause may not be the same. It will be interesting to see how the Mantle version will perform under both operating systems.
"Is in-game real world Battlefield 4 gaming performance better on the Windows 8.1 operating system or on Windows 7? We look at video card performance between Windows 7 and Windows 8.1 in this game and find out if upgrading to Windows 8.1 is worth it or not for the much rumored performance advantage."

Though a little bit outside our normal coverage area, I wanted to share a quick video we made this morning that shows off the new Nest Protect smoke and carbon monoxide detector. Much like the Nest thermostat released a couple years ago, the smoke detector takes a new approach to this bland and "dumb" device in your home. It connects to Wi-Fi for alerts, speaks in a human tone about warnings and is intelligent enough to let you know in what room the emergency is occurring.

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.
"PROCESSOR CHIP SALES will increase by almost quarter this year thanks to the growing demand for mobile devices such as smartphones and tablets, analyst outfit IHS has predicted."

Parts and labor costs have surfaced for the Xbox One and Playstation 4. Last time around, both Microsoft and Sony were bleeding over a hundred dollars each time a console was produced and sold before you even consider research, development, support, and so forth. This time, both are fluttering around the break-even point.
Console fans commonly say, "You cannot build an equivalent gaming PC for what I can get a console for." My response has been, "Correct and neither can Sony or Microsoft; they are bleeding to gouge you later. Add up those license fees and PC gaming is often cheaper." That may change.
Easier for developers... and their CFO.
While it has not changed that PC gaming can still be cheaper, because it has less middlemen demanding license fees, the consoles might not be losing as much money. Last week, IHS iSuppli inventoried the Playstation 4 and determined that it costs Sony around $381 USD for every $399 console they sell. The Xbox One has also had its turn: $471 USD for the $499 device.
This may seem a lot, but the $499 launch PS3 (20GB) cost Sony $805.85 in parts and labor. The Xbox 360 was less devastating for Microsoft at a cost of $525 for their $399 console. None of these fees include research, development, support, store markup (if they are allowed any), etc.
The last generation of consoles, despite its length, may or may not have delivered any profit for either party. The recent several quarters of profits are easily offset by many more of losses. I expect that neither company is interested in repeating the last generation. It hurt.
But the consoles, despite being cheaper than last time, could still have a reasonable lifespan. A large chunk of the original PS3 bill of materials was the hardware "Emotion Engine" (most links are broken by now but I believe it was about as much per chip as the Cell processor). The consoles are now based upon commodity PC hardware. They can finally take advantage of the competition between other companies to focus their research and development costs on the platform itself.

Tagged: amd, Mantle, apu13
The Tech Report learned quite a bit about Mantle at APU 13, focusing much more deeply on what Mantle is and how it will work. To think of it as a replacement for DirectX is a good start as it is an API but it also changes how your system interacts with your GPU. The briefing delves into to the technical side, describing the context-based execution model which Mantle uses to give you proper access to assign tasks to multiple processors or other resources as the memory interface is also completely revamped. There are four pages describing Mantle for your reading pleasure here and with the strong early adoption it would be worth your time to learn more about it.
"At its APU13 developer conference in San Jose, California, AMD invited journalists and developers to listen to hours worth of keynotes and sessions by Mantle's creators and early adopters. We sat through all of it—and talked to some of those experts one on one—in order to get a sense of what Mantle does, how it will impact performance, and what its future may hold."

Tagged: ssd, endurance
Update 11/26/2013 @ 11:20pm Allyn weighed in, particularly about the Samsung drives. One thing that he notes (as does Tech Report in the original article) is that Samsung might just be more severe in its reporting of errors. For instance, he believes that it is just about impossible for SSDs to write 300TB of data without ever seeing a flash read error. Regardless of what they report, each of these drives keep on ticking. It is "significantly beyond the expectations of a consumer (non-Prosumer) SSD".
The Tech Report has been testing a batch of SSDs for their life expectancy over several months now. Results have been fairly interesting: drives were relatively stable even up to 200TB of cumulative writes; some drives even got faster. Now they have passed the 300TB threshold and we are seeing certain drives hit some harsh realities. As Scott Wasson said in a tweet:
Our endurance experiment has finally hit the limits of one consumer SSD: http://t.co/zxw7mRkT2K
— Scott Wasson (@scottwasson) November 26, 2013
In all, though, even the TLC offerings have surpassed reasonable expectations. Consumer drives are designed for consumer machines and will likely take decades to reach the hundreds-of-terabytes order of magnitude for today's usage.

It makes me wonder exactly how over-provisioned enterprise hardware is if these, consumer, parts have such high reliability.
