Third-generation Apple TV A5 processor studied, second core found

This is sort of interesting.

An investigation into the custom A5 chip used in Apple TV has found that the new Application Processor uses both a smaller, more efficient 32nm die process and actually incorporates two cores, one of which is simply turned off.

Per Chipworks, the custom A5 “APL2498” used in the third generation, 1080p Apple TV has improved upon the 45nm LP CMOS process of the previous A5 “APL0498,” used in both iPad 2 and iPhone 4S last year.

The smaller die size makes the Apple TV’s A5 almost 41 percent smaller than the original part, allowing more chips to be created from a single silicon wafer. That makes producing the part cheaper, and also helps improve performance and lower power consumption (as its components are shrunken down and therefore closer to each other).

In addition to being smaller, Chipworks found that the new version of the A5 actually incorporates two cores. Apple only advertises Apple TV as having a single core chip, so the investigation notes that “either Apple is only utilizing one core or they are binning parts.”

By turning off one core, Apple could reduce the power consumption of a device. However, Apple TV lacks the power constraints of battery-powered mobile devices, making it more likely that the company simply developed a smaller, cheaper version of the A5 and is using the dual core rejects to power Apple TV, where one core is sufficient.

Chipworks explains that such “parts binning is a common process in semiconductors where devices are segregated (binned) based on meeting a subset of the overall requirements, in this case they could disable the ‘bad’ core, this increases the usable die per wafer, lowering the cost.”

Chip makers routinely create CPUs and RAM components and test them for the highest speed they can consistently operate at, selling the fastest parts for more and the slower components for less, rated to work at a slower clock speed.

This strategy would allow Apple to use its poorest performing new A5 chips in the US$99 Apple TV, while creating a new supply of fully functional 32nm A5 chips that are faster, smaller and cheaper than last year’s 45nm batch.

Chipworks notes that these chips could either power a new generation of iPhones (or other devices) or help to reduce the cost of existing products such as the iPhone 4S or iPad 2. The latest third generation iPad uses a custom chip Apple calls A5X, which incorporates the same dual ARM cores but delivers quad-core GPUs to drive its Retina Display, with four times the pixels.

Early Ivy Bridge benchmark tests surface, show appreciable improvements in graphics, overall performance

It’s the benchmarks that make an upcoming technology that much more interesting.

Per CPU World, a series of benchmark tests demonstrates how the much-anticipated Ivy Bridge architecture in the upcoming MacBook Pro notebooks could show fairly significant improvements in performance, particularly in graphics.

The chip being tested was the Core i7-3820QM, a 2.7 GHz processor with turbo speeds up to 3.7 GHz paired with Intel HD 4000 graphics. The chip is scheduled to debut with a price of US$568 in high volume, and seems to be the natural successor to the Sandy Bridge Core i7-2860QM that is the current high-end processor for the 15-inch and 17-inch MacBook Pro, available as a build-to-order option.

For benchmarking comparisons, the new Ivy Bridge Core i7-3820QM chip was pitted against a Sandy Bridge Core i7-2960XM, which is an even higher-performance “Extreme” chip than is available in the current MacBook Pro. Consequently, any performance increase between the current high-end MacBook Pro chip and this new Ivy Bridge chip would be even greater than outlined in the benchmarking comparison.

Overall, the 3820QM was found to score an average of 9% higher than the Extreme 2960XM chip, a modest improvement but one which should be significantly higher relative to the 2860QM chip from the current MacBook Pro. Taking into account a roughly 10% higher performance for the tested 2960XM Sandy Bridge processor compared to the 2860QM actually found in the current MacBook Pro, the new 3820QM Ivy Bridge processor should offer roughly 20% higher CPU performance than is currently available in the MacBook Pro.

Looking at the CPU performance, using a few tests, the reduced production process helps the performance for a number of standard tests. In 3DMark Vantage (Entry level preset), Ivy Bridge has a 10% performance improvement over Sandy Bridge for the CPU score, and 9% in the physics score. In Cinebench 11.5, the single thread test showed a performance boost of 4%, and the multi-threaded test gave an improvement of 10%. The performance boost in the Truecrypt 7.0a – AES test was 4%. Finally, using x264 HD Benchmark 4.0, test 1 showed a boost of 13%, and test 2 showed a boost of 11%.

Even more significant gains for the Ivy Bridge chip show up in graphics performance, where the Intel HD 4000 integrated graphics supplants the HD 3000 graphics found in the Sandy Bridge chips. According to the benchmarks, the new HD 4000 integrated graphics outperforms the current graphics by anywhere from 32% to 108% depending on the test.

Apple, of course also includes a dedicated graphics chip in its larger MacBook Pro models, giving users the option of higher performance with the dedicated chip or increased battery life with the integrated graphics. And given that the HD 4000 integrated graphics does not yet approach the performance of dedicated chips, those looking for maximum performance will still want to take advantage of whichever dedicated graphics option Apple includes in updated MacBook Pro models.

But significant improvements to integrated graphics performance could show up as a benefit in a number of areas, including providing users with better performance even when opting for the battery-conserving graphics settings. Apple has also reportedly been considering using integrated graphics only in some of its mid-range MacBook Pro models, with the HD 4000 chip making it feasible for the company to drop the dedicated graphics chip on some of those models while still being able to offer acceptable graphics performance.

Finally, the HD 4000 graphics will offer a marked improvement for the 13-inch MacBook Pro, which is expected to debut in June when Intel rolls out its dual-core Ivy Bridge processors. The smaller 13-inch form factor requires that those models rely solely on integrated graphics, meaning that all users would see a significant boost from the current HD 3000 graphics to the new HD 4000 graphics.

Retina Display supplies constrained by demand, shift in labor practices for Foxconn workers

If you don’t have enough of a given part, it makes assembly a bit harder.

Then there’s the awkward part about easing working conditions for your labor force…

Per AppleInsider, demand for Apple’s new iPad remains strong, but production of the device has reportedly been limited by supply of Retina displays, as well as a new focus on employees at Foxconn that has resulted in worker hours being cut.

Analyst Shaw Wu with Sterne Agee aimed to quash some investor concern on Wednesday that demand for the new iPad is waning. That’s not true, he said, as his checks within Apple’s supply chain have found that the company continues to have strong interest in its latest touchscreen tablet.

Instead, he said, it’s supply of the new high-resolution Retina display that has limited shipments of the latest iPad. He expects that situation to improve over the coming quarters, as additional production lines and suppliers are added.

Samsung is currently believed to be the primary supplier of Retina displays for the new iPad. Both LG and Sharp were said to have initially struggled in making the high-resolution screens for Apple, but recently began small-volume shipments.

Another factor in iPad supply, Wu said, has been the fact that Foxconn is now “conforming to more sound labor practices.” Last month, following an independent audit by the Fair Labor Association, Apple’s manufacturing partner Foxconn agreed to fix a number of violations that were discovered, including excess working times by its factory employees.

“This is in an effort to improve working conditions,” Wu said. “From our understanding, the irony is that many employees prefer to work more overtime.”

Some Foxconn workers publicly questioned last month why their hours were being cut after the review conducted by the FLA. Foxconn reduced employee working hours to 49 per week, including overtime, but the change will also result in smaller paychecks for workers.

Because iPad production has apparently been slowed by factors other than demand, Wu has opted to raise his estimates for sales in the current quarter. He now sees Apple having sold 12.3 million iPads in the already-concluded March quarter, up from his previous forecast of 11.5 million.

Apple developing program to track, destroy Flashback malware

I think this is where an awesome montage scene of productivity/progress begins in an 80s movie. Or at least the cast involves vows to achieve a long-term goal.

Apple revealed on Tuesday that it is currently developing software to detect and remove the Flashback malware that has infected an estimated 600,000 Macs worldwide.

The company made mention of the upcoming tool in a support document regarding the malicious software, as noted by The Loop. The document also pointed users to last week’s Java update that patched the security flaw that the virus was exploiting.

“In addition to the Java vulnerability, the Flashback malware relies on computer servers hosted by the malware authors to perform many of its critical functions. Apple is working with ISPs worldwide to disable this command and control network,” the company said.

Apple also advises Macs running OS X 10.5 or earlier to disable Java in their browser preferences.

The Flashback trojan horse was first discovered last September. The malware posed as a phony Adobe Flash Player installer in order to trick users into installing it. At the time, a security first categorized the threat as “low.” The current version of Flashback used the Java vulnerability to create a botnet that could mine personal information from unsuspecting users.

Evidence of Apple’s efforts to contact ISPs surfaced earlier on Tuesday when a Russian security firm revealed that the company had targeted one of its servers as being “involved in a malicious scheme.” Dr. Web chief executive Boris Sharov said the server was “not doing any harm to users” and was being used to monitor the spread of the virus.

Sharov noted that the relative rarity of Apple security issues meant that Dr. Web hadn’t established close ties with the company. “For Microsoft, we have all the security response team’s addresses,” he said. “We don’t know the antivirus group inside Apple.”

Last week, a Dr. Web analyst claimed that 600,000 Macs around the world had been infected by the Flashback malware. 56.6 percent of those infections are reportedly located in the U.S.

U.S. government to work with wireless carriers to create national stolen phone database

Posted by:

Category: iPhone, News

This could be perceived as sort of “Big Brother”-ish, but also pretty helpful.

Per the Wall Street Journal, four of the largest wireless carriers in the US are working with the US government to create a national stolen phone database. Verizon Wireless, AT&T, Sprint and T-Mobile will develop their own databases and then merge them into a centralized server within the next 18 months. Eventually, regional carriers will also participate in this initiative.

The database will help carriers and law enforcement track lost and stolen phones. Besides tracking phones, carriers have agreed to block both calling and data services for these blacklisted phones. This will be an easy task for Verizon and Sprint, but not so simple for T-Mobile and AT&T.

Verizon Wireless and Sprint already track each subscriber’s phone using the phone’s unique electronic serial number. This lets them easily block any phone that’s been reported lost or stolen. AT&T and T-Mobile do not have a similar service in place, because their GSM phones use SIM cards. As long as you have a valid SIM card, you can use any phone, regardless of whether it is lost or stolen. These two GSM carriers are working on new technology that would let them track and block a phone using a unique ID.

Inventory constraints point towards possibility of new 15-inch MacBook Pro notebook on horizon

When the current supplies dwindle, interesting things are about to happen.

Per AppleInsider, multiple authorized resellers this week are reflecting stock-outs of 15-inch MacBook Pros, suggesting that Apple is ramping down production of existing models before introducing redesigned offerings that will largely resemble the company’s increasingly popular line of ultra-slim MacBook Airs.

Among those resellers reflecting backorder status on some of the current 15-inch MacBook Pros is J&R, which is now sold out of both the 2.2GHz model, which is listed as “out of stock,” and the 2.4GHz variety, which is currently advertised as “on order.”

In addition, Best Buy has also stopped accepting online orders for the 2.4GHz model for home delivery. The 15-inch notebook is still available on a store-by-store basis, however a quick check of individual store inventory in cities such as Chicago and Austin similarly indicate that between 40 and 60 percent of those shops are similarly reflecting stock outs.

Earlier this week, MacConnection was temporarily out of stock the 2.2GHz model of Apple’s 15-inch MacBook Pro, but the notebook has since come back in stock at the online retailer.

Multiple instances of inventory constraints within Apple’s indirect sales channel are often some of the first signs that the Mac maker is drawing down stock and slowing shipments of existing models before replacing them with materially enhanced offerings. This week’s stock-outs come as Intel is gearing up to launch its Ivy Bridge chips, which have been rumored to begin finding their way into Apple’s Mac product line as early as this month or next.

Apple appears to be planning a staggered overhaul of the MacBook Pro lineup, beginning with an updated 15-inch model, followed by the 13-inch, and ultimately the 17-inch by the end of the year.

Recent rumors have claimed production of the 15-inch model will begin this month with 200,000 units, while production of the new the 13-inch MacBook Pro will occur in June with builds of 400,000 initial units.

The new 15-inch MacBook Pro is rumored to arrive as soon as this month with Intel’s Core i5 and Core i7 Ivy Bridge processors. Reports have suggested Apple’s new notebooks could include Intel’s Core i7-3820QM and Core i7-3720QM models featuring integrated HD 4000 graphics.

There are fewer details on the forthcoming 13-inch MacBook Pro, as one report from March said it was “not clear” if Apple planned to introduce a new MacBook Pro with an entry-level Core i3 Ivy Bridge processor. All of Apple’s current “Pro” laptops feature only higher-end Core i5 and Core i7 processors.

The new MacBook Pros are expected to be noticeably thinner and lighter in design, and will eschew the spinning disc drive to adopt a form factor similar to Apple’s thin-and-light MacBook Air. The MacBook Pro lineup was given a quiet update with faster GPUs and graphics cards last October, while the last major redesign of the lineup came in late 2008.

Separately, in what could be a sign of the end of the Mac Pro desktop line, Amazon is currently out of stock of the 8-core model.

Stay tuned for additional details as they become available.
