Interesting information has surfaced today about the addition of a new executive at AMD. Raja Koduri, who previously worked for ATI and AMD as Chief Technology Officer, departed the company in 2009 for a four year stint at Apple, helping to turn that company into an SoC power house. Developing its own processors has enabled Apple to stand apart from the competition in many mobile spaces and Koduri is partly responsible for the technological shift at Apple.
Starting on Monday though, Raja Koduri is officially back at AMD, taking over as the CVP (Corporate Vice President) of Visual Computing. This position will result in more complete control over the entirety of the hardware and software platforms AMD is developing including desktop discrete, mobile and APU/SoC designs. This marks the second major returning visionary executive in recent memory to AMD, the first of which was Jim Keller in August of 2012 (also returning from a period with Apple).
It will take some time for Koduri to have effect on AMD's current roadmap
Having known Raja Koduri for quite a long time I have always seen the man as an incredibly intelligent engineer that was able to find strengths in designs that others could not. Much of the success of the ATI/AMD GPU divisions during the 2000s was due to Koduri's leadership (among others of course) and I think having him back at AMD at an even more senior role is great news for both discrete graphics fans and APU users.
In a discussion with Koduri recently, Anandtech got some positive feedback for PC gamers:
Raja believes there’s likely another 15 years ahead of us for good work in high-end discrete graphics, so we’ll continue to see AMD focus on that part of the market.
Koduri sees 15 years more GPU evolution
So even though this hiring isn't going to change AMD's position on the APU and SoC strategy, it is good to have someone at the CVP level that sees the importance and value of discrete, high power GPU technology.
In many talks with AMD over the last 6 months we kept hearing about the healthy influx of quality personnel though much of it was still under wraps. Keller was definitely one of them and Koduri is another and both of the hires give a lot of hope for AMD as a company going forward. Some in the industry have already written AMD off but I find it hard to believe that this caliber of executive would return to a sinking ship.

Tagged: apple, Intel, rumour, running gag
Once again the old rumour has resurfaced and discussions of what will happen to the market if Apple chooses Intel to manufacture their mobile chips. As we heard at the end of last year, Intel might be willing to fab ARM processors for iPhones if Apple is willing to move to x86 processors for other larger mobile products. Today via The Register we heard more about the possibility of the two companies working together, though no real confirmation has yet been made. This move makes sense for Intel who are not making revenue from the mobile market and even more sense for Apple who are in the midst of suing their current chip provider Samsung in multiple cases across the planet.
"Rumors are again swirling that Apple and Intel are in discussions about Chipzilla baking the chips Cupertino uses to power its iDevices.
"A source close to one of the companies says Intel and Apple executives have discussed the issue in the past year but no agreement has been reached," Reuters reported on Thursday."

Two different mobile phone security concerns were revealed today, one for devices using iOS 6.1 and one for Androids. DailyTech has posted text instructions as well as linking to a video which shows how an iPhone 5's password protection can be completely bypassed and allow anyone with physical access to your phone to log into the phone with full access. The second vulnerability, tested with Android 4.0 but possibly wide spread, was discovered by a team at the Friedrich-Alexander University in Germany, and it allows you to recover information from a phone which has used the Android disk encryption. They used both a freezer to drop the temperature of the phone and a trick with the battery which puts the phone into 'fastboot' mode and allows the loading of a custom image via a Linux PC which installs their Forensic Recovery Of Scrambled Telephones tool, aka FROST. As you can see from the images below, that gives you the ability to get the encryption key or even brute force some passwords.
-Go to emergency call, push down the power button and tap cancel.
-Dial 112 and tap green and inmediately red.
-Go to lock screen.
Ok...ready for second part:
-Go to passcode screen.
-Keep pushing down the power button ...1...2...3...seconds and before showing the slider "turn off"...tap the emergency call button and ...voilá!
-Then without releasing the power button press the home button and ready..."

The good news for Samsung last year is that it bought $23.9bn worth of semiconductor orders in 2012, while Apple ordered a mere $21.4bn which implies that Samsung is buying more chips than Apple, or perhaps is just getting a worse deal. If the information from Gartner that The Inquirer picked up on is correct, Samsung accounted for 8% of the total semiconductor market in 2012, a very impressive feat. That is more than Dell and HP's market share combined which supports the theory that the falling sales we saw in PCs was not reflected at all in the smartphone and tablet markets.
Unfortunately that success comes at a price as Samsung's OS of choice, Android, is expected to see more than one million malware threats by the end of 2013. According to Trend Micro there were about 350,000 malware threats over 2012 with only one in five Android devices actually having any sort of security software installed. Perhaps it is time to start thinking more about protecting your phone, especially if you have banking apps or the so called "pay by bonk" enabled on your phone.
"Apple, thanks in large part to its hugely popular iPhone and iPad products, was the largest consumer of semiconductor chips, that is, until 2012. Gartner claims that Samsung has overtaken Apple to become the largest semiconductor user with eight percent of all chips sold going to the firm."

Tagged: apple, Samsung, TSMC, A6X
According to the news we are hearing from Slashdot and other sources, Apple has finally made the decision to move their chip fabrication from Samsung, for fairly obvious reasons, with TSMC being the lucky fab that will get their business. They are starting with the current A6X chip, shrinking it to 28nm for the initial run, with the contract for producing the new A7 series dependant on the success of TSMC's trial run. As the 28nm node is quite familiar to TSMC, barring any production issues that limit availability, they are very likely to win the contract.
"The test will kick off in Q1 2013, The China Times reports, with TSMC producing a new, 28nm version of the existing 32nm A6X that Samsung has been producing for the full-sized iPad 4th-gen; the smaller chip, which will likely be more power efficient as well, will debut in a new iPad 5th-gen and iPad mini 2."

Since the Apple transition to Intel processors and mostly off-the-shelf PC hardware in 2006, people have been attempting to run OS X on home built computers originally destined for Windows. While running a different operating system on similar hardware may seem like a trivial thing, my historical experience with building a so called “Hackintosh” has been arduous at times. However, since it has been a few years since my last attempt, I decided to give installing OS X on modern PC hardware another try.
Otellini will never live that one down...
One of the big stepping stones for OS X on PC based motherboards was the widespread adoption of EFI instead of the standard BIOS environment. Official Intel Macs have always used EFI, which meant until a few years ago, emulating the EFI environment on third party motherboards to build a Hackintosh. That has changed recently and with the release of Sandy Bridge, we have seen full EFI support across all motherboard vendors.
The premiere source for information about Hackintosh builds is the tonymacx86 site and forums. The forums on tonymac is an extremely useful resource for learning about the current state of the Hackintosh scene and the experiences of people with similar hardware to what we will be using.
Tony publishes a yearly Buyer’s Guide article with components of all price ranges that will work with OS X with minimal hassle. He provides many different options in different price ranges in the 2012 guide, including H77, Z77, and even X79 based parts.
While it is technically possible to use AMD processors and graphics cards in a Hackintosh build, Apple officially supports Intel CPUs and NVIDIA Kepler GPUs, so they require much less work to ensure the operating system can fully utilize these components.

Hopefully I did not make your head hurt too much with that title.
Intel announced early in the year the opening of their fabrication labs to certain other developers, none of which competing with anything Intel does. We joked about how this is the end of the world as we know it although we feel fine. As it turns out, the world might end December 2012: RBC rumors that Intel might fulfill orders of ARM processors taking away that responsibility from Samsung.
Of course, there will always be a catch. It is possible that Intel will allow Apple to manufacture their ARM-based processors at Intel if Apple switches their tablets to x86-based products. No-one said the apocalypse must be an irrational event.
When pigs fly? Challenge accepted.
If this rumor comes to fruition - and that is a mighty large if - we finally know that a line of apathy exists within Intel. Intel fabricating an architecture that they directly compete with is a big deal, ignore their motive.
Intel has allegedly made a compromise, definitively this time. We debated fairly heavily whether Intel made a compromise when they allowed FBGAs to be manufactured at their facilities. This time there is no question about whether Intel will make a concession to better its company as a whole.
I have no doubt that Intel desires to stomp competing platforms but we should all doubt that Intel would never step into some middle ground. After all, Intel is not even suffering at this point by any measure. Imagine if the situation actually begins to look dire.

Tagged: hybrid, fusion drive, fusion, apple
Dubbed 'Fusion Drive', this tech enables the late 2012 Mac Mini and iMac models to have a pseudo-hybrid drive. There's been a lot of speculation today on just how this technology will work, but I've cut through the chaff to try and shed some proper light on just how this new thing works, and how it is so different than any other 'hybrid' solution out there.
First, it's not a hybrid drive. The iMac or Mac Mini comes with an SSD and a HDD. Two individual SATA devices. Both devices appear as individual drives, even in Disk Utility. Where the magic happens is that OSX can be configured (and is pre-configured in these new systems) to combine the two drives into one drive that presents itself to the user as a single logical volume. The important point is that the drives are 'fused' together, not merged or mirrored. The SSD and HDD each have their own partition, and OSX can reach beneath the Fusion layer and shift files back and forth between the two as it sees fit. Frequently used apps and files can be shifted back and forth between the SSD and HDD, as seen in the below pic:
The biggest differences are in that since it's not a mirrored hybrid solution, where the SSD space is not available, and a failure of the HDD causes loss of all data. Fusion Drive combines the two volumes and *adds* the space together, and the apps or files will sit on either device (but not both). All files written go to the SSD first and are later shifted to the HDD in the background. This is actually a very smart way to handle things. The entire OSX install always stays on the SSD, so there is no concern of OS files 'rolling off' of the SSD cache, causing intermittent slowdowns. More (perhaps most) importantly, if the HDD fails on a Fusion Drive setup, OSX should theoretically just keep on chugging, albeit without access to the files or apps that were stored on the HDD. On the flip side, if the SSD were to fail, the HDD could simply be mounted in Target Mode under another Mac, and all files stored to that drive could then be recovered. Sure you won't get everything back in these scenarios, but it provides *much* more flexibility for data recovery, and it's worth repeating the fact that an HDD failure in any other hybrid solution results in the loss of ALL data.
A couple of other quick gotchas: You can still dual boot with boot camp under a Fusion Drive setup, but the boot camp partition will only be at the end of the HDD, not on the SSD. Windows will not only run slower because it's on the spinning disk, it will run slower because the latter portions of a HDD typically see about half of the throughput as compared to the start of that disk. Also, you are only allowed *one* additional (non-Fusion) partition on the HDD, which can be used for another OSX install *or* for the Boot Camp Windows install. Users who prefer to boot greater than two operating systems on their newer Mac will have to do so with Fusion Drive disabled.
More to follow as more data comes in. For now I'm only working off of the other speculation and the Apple Support Page on the matter.

Tagged: SoC, PowerVR, iphone, arm, apple, a6
Apple's latest smartphone was unveiled earlier this month, and just about every feature has been analyzed extensively by reviewers and expounded upon by Apple. However, the one aspect that remains a mystery is the ARM System on a Chip that is powering the iPhone 5. There has been a great deal of speculation, but the officially Apple is not talking. The company has stated that the new processor is two times faster than its predecessor, but beyond that it will be up to reviewers to figure out what makes it tick.
After the press conference PC Perspective's Josh Walrath researched what few hints there were on the new A6 processor, and determined that there was a good chance it was an ARM Cortex A15-based design. Since then some tidbits of information have come out that suggest otherwise, however. Developers for iOS disovered that the latest SDK suggest new functionality for the A6 processor, including some new instruction sets. That discovery tended credence to the A6 possibly being Cortex A15, but it did not prove that it wasn't. Following that, Anandtech posted an article that stated it was in a licensed Cortex A15 design. Rather, the A6 was a custom Apple-developed chip that would, ideally, give users the same level of performance without needing significantly more power – and without waiting for a Cortex A15 chip to be manufactured.
Finally, thanks to the work of the enthusiasts over at Chipworks, we have physical proof that, finally, reveals details about Apple's A6 SoC. By stripping away the outer protective layers, and placing the A6 die under a powerful microscope, they managed to get an 'up close and personal' look at the inside of the chip.
Despite the near-Jersey Shore (shudder) levels of drama between Apple and Samsung over the recent trade dress and patent infringement allegations, it seems that the two companies worked together to bring Apple's custom processor to market. The researchers determined that the A6 was based on Samsung's 32nm CMOS manufacturing process. It reads APL0589B01 on the inside, which suggests that it is of Apple's own design. Once the Chipworks team sliced open the processor further, they discovered proof that Apple really did craft a custom ARM processor.
In fact, Apple has created a chip with dual ARM CPU cores and three GPU cores (PowerVR). The CPU cores support the ARMv7s instruction set, and Apple has gone with a hand drawn design. Rather than employ computer libraries to automatically lay out the logic in the processor, Apple and the engineers acquired from its purchase of PA Semi have manually drawn out the processor by hand. This chip has likely been in the works for a couple of years now, and the 96.71mm^2 sized die will offer up some notable performance improvements.
It seems like Apple has opted to go for an expensive custom chip rather than opt for a licensed Cortex A15 design. That combined with the hand drawn layout should give Apple a processor with better performance than its past designs without requiring significantly more power.
At a time when mobile SoC giant Texas Instruments is giving up on ARM chips for tablets and smartphones, and hand drawn designs are becoming increasingly rare (even AMD has given up), I have to give Apple props for going with a custom processor laid out by hand. I'm interested to see what the company is able to do with it and where they will go from here.
Chipworks and iFixIt also took a look at the LTE modem, Wi-Fi chip, audio amplifier, and other aspects of the iPhone 5's internals, and it is definitely worth a read for the impressive imagery alone.
Apple Produces the new A6 for the iPhone 5
Today is the day that world gets introduced to the iPhone 5. I of course was very curious about what Apple would be bringing to market the year after the death of Steve Jobs. The excitement leading up to the iPhone announcement was somewhat muted as compared to years past, and a lot of that could be attributed to what has been happening in the Android market. Companies like Samsung and HTC have released new high end phones that are not only faster and more expansive than previous versions, but they also worked really well and were feature packed. While the iPhone 5 will be another success for Apple, for those somewhat dispassionate about the cellphone market will likely just shrug and say to themselves, “It looks like Apple caught up for the year, but too bad they really didn’t introduce anything really groundbreaking.”
If there was one area that many were anxiously awaiting, it was that of the SOC (system on a chip) that Apple would use for the iPhone 5. Speculation went basically from using a fresh piece of silicon based on the A5X (faster clocks, smaller graphics portion) to having a quad core monster running at high speeds but still sipping power. It seems that we actually got something in between. This is not a bad thing, but as we go forward we will likely see that the silicon again only matches what other manufacturers have been using since earlier this year.
