Audi’s A6 offers A7 performance for less money
The recently refreshed Audi A6 (starting at $58,900) isn't quite as nice as the refreshed A7 with its cool Sportback rear or the A8 with all-wheel steering. But that shouldn't deter you from taking one for a spin if you're shopping for it's more expensive siblings. In fact, in the bang-for-buck roundup, it's probably the Audi sedan to buy if you're more interested in performance over luxury.
AMD's latest laptop CPUs include its first chips for Chromebooks
AMD is kicking off 2019 with an overhaul of its laptop processors, and it's breaking some new ground in the process. The company has unveiled its first two A-Series chips designed explicitly for Chromebooks, the 1.6GHz A4-9120C and 1.8GHz A6-9220C. Both are dual-core chips that use just 6W of power and promise faster performance than the Intel chips you typically see in entry-level Chrome OS portables. The A6 is up to 23 percent faster in web browsing than the Pentium N4200, AMD said, and 42 percent faster in photo editing. You might not have to spend a small fortune to get a Chromebook with decent horsepower.
Bang and Olufsen couldn't convince me a speaker is worth $1,000
Bang and Olufsen is known for two things: unique design and high prices. Sometimes, the cost isn't so much of an issue if the design is matched by quality audio or a solid display panel. The company's new BeoPlay A6 is a $1,000 wireless speaker with three modes to change its sound based on where it's placed in a room. With Sonos and others already offering similar products for a fraction of the price, I was unsure if B&O's latest product would live up to steep asking price. Unfortunately, my suspicions were correct.
Apple allegedly working with Samsung again on chips for 2015 devices
Samsung has been exclusively making chips for Apple's iOS devices since the first iPhone started shipping in 2007 -- we don't need to tell you that makes for an odd relationship. Several months ago, The Wall Street Journal reported that Apple would switch to TSMC for next year's iOS portfolio, but now there's some strange news coming out of Korea. According to a local publication, Apple's 2015 iOS devices will use Samsung's 14 nanometer FinFET technology, starting with the iPhone 7 (not the 6S?). Why would Apple switch to TSMC for just one year and then go back to Samsung? Is Apple planning to rely on both TSMC and Samsung for different product lines? Unfortunately, we'll have to wait until Chipworks breaks out its microscopes to find out what's really going on.
AMD rolls out Elite desktop APUs with Splashtop game streaming
AMD has already shown what its mobile Richland APUs can do, and it's now ready to reveal their desktop equivalents' potential. The company's new, full-power A6, A8 and A10 Elite processors are more evolutionary bumps than overhauls, but they still have a few clear advantages over last year's Trinity chips. Along with a bump in Turbo Boosted frequencies to between 4.1GHz and 4.4GHz (3.5GHz to 4.1GHz normally), the updates ship with Radeon HD 8000 video and can handle speedier DDR3-2133 memory (on the A10). Wireless is just as important as it is with the firm's newest mobile processors: the desktop Elites improve streaming games to other devices using Splashtop, with relatively little lag when modern AMD processors are on both ends. As for performance? AMD didn't have the luxury of comparing against Intel's Haswell chips at the time it gave us benchmarks, but it did claim big gains over Ivy Bridge in both general-purpose computing and gaming. A 4.1GHz A10-6800K is up to 3.3 times faster in OpenCL than a 3.2GHz Core i5-3470, and games like Bioshock Infinite are playable at 1080p (if barely) where they're unusable with the HD 3000 graphics of Intel's CPU. Performance boosts over Trinity are a more modest eight to 21 percent, however. If you want to know how well the Elite line fares in the real world, it won't take much effort to find out. AMD is shipping its processors this month, at very frugal prices that range from $69 to $142. %Gallery-190368%
AMD details Elite Mobility and mainstream APUs, we run early tests (hands-on)
AMD has been willing to tease its 2013 ultra-mobile APU (accelerated processing unit) strategy through PCs like the Acer Aspire V5, but today it's spilling the beans in earnest. The headliner for many is the company's just-shipping Elite Mobility line, or Temash: the A4 and A6 designs are built for tablets, like Hondo was, but their Jaguar-based system-on-chip designs should be faster in both CPU and graphics power without a hit to battery life. AMD estimates that the Radeon HD 8280G video core in an Elite Mobility A6 is about five times faster than a Clover Trail-based Atom and twice as fast as Hondo, but lasts about 45 percent longer on battery than an Intel Core i3. And that's while untethered -- that Turbo Dock feature is still in place to boost speeds by over 30 percent when a dock is around for extra cooling. The E1, E2, A4 and A6 mainstream APUs based on Kabini, meanwhile, are all about tackling the Pentium and Core i3 chips that go into entry-level laptops. AMD reckons that the dual-core (E-series) and quad-core (A-series) parts are up to 88 percent faster overall than their ancestors, and can even punch above their weight class: the E1's Radeon HD 8000-level graphics are up to 66 percent faster than those of a much thirstier, Trinity-era A4 chip. Battery life is a specialty as well, with up to 10 hours when idle and 9 hours of web use. That's typically 2 to 3 hours more than Kabini's Brazos ancestor could manage. AMD wasn't specific on when these mainstream APUs would first ship when we were briefed, but we had the opportunity to benchmark an A4-based reference laptop. Read on past the break for the scores and some early impressions. %Gallery-189169% %Gallery-189171%
AMD outlines Elite Performance laptop APUs with game-ready Wireless Display
AMD isn't focusing all its attention on its entry-level mobile APUs today: it's also providing details for the faster Richland-based models. The new A6, A8, and A10 mobile variants fall under the Elite Performance badge, and theoretically beat Intel to the punch with up to 71 percent faster 3D graphics than the current Core i5 family. They also muster about 7.5 hours of battery life with web use, or about an hour longer than we saw in the previous generation. The roster includes both regular power (35W) and low-voltage (17W to 25W) APUs, in dual- and quad-core editions. We're more interested in how well the chips play with other devices and software, however. Besides the face and motion gesture recognition that we've seen before, AMD touts a new take on Wireless Display with low enough latency for game sessions, support for 1080p60 video and native Miracast sharing. The Richland upgrade also introduces a new DockPort standard that can feed both USB 3.0 and up to three external DisplayPort screens through one cable. If you like what AMD is pitching, you won't have to wait to try it -- Elite Performance APUs have already been shipping with MSI's GX60 and GX70, and other vendors shouldn't be far behind. %Gallery-189172%
Apple may ditch Intel chips in Macs, says Bloomberg
According to Bloomberg Apple is considering a move away from Intel chips for its cherished Mac line. The change would be the third major CPU shift for the brand which has previously relied on Motorola 68000 and Power PC chips. Ditching Intel silicon could also mean a move away from x86, as Apple has been heavily invested in its own ARM-based chip designs in recent years. Bloomberg's sources suggest that Cupertino is actively working on a version of its tweaked ARM architecture that would run inside Mac PC, in particular its laptop products could stand to benefit from its battery sipping design. The change will not happen immediately. In fact, the sources said such a move was years away, potentially not happening till 2017. But, as the gulf between "mobile" and "desktop" products begins to shrink and the boundaries blend, it would only seem to make sense that Apple would look to leverage its high-profile purchase of P.A. Semi to good use and inch ever closer to being a completely self-reliant corporate entity. We don't think it's any secret that Apple would, if it could, design and manufacture all of its products' components in-house.
The A6 inside the iPhone 5 varies its clock speed for performance
One possible reason the iPhone 5 has such great battery life is the clever way the A6 changes its clock speed. While originally thought to be clocked at 1GHz, the chip has been clocked at 1.1GHz as well as 1.3GHz by Current Editorials. While 9to5Mac saw the chip's speed drop as low as 550MHz, this seemed to do more with an as-yet-updated Geekbench app testing the chip (which also resulted in the 1GHz assumption). A Geekbench update seems to paint a different picture now. By all accounts it appears the chip can change "speeds," however, resulting in better battery life and dynamically tuning itself to the demand for CPU. Between this and the human-powered layout found in the dissection of the A6, it's obvious Apple's decades of hardware expertise have all led to creating an amazing CPU for the iPhone 5.
Apple's A6 CPU actually clocked at around 1.3GHz, per new Geekbench report
As the initial wave of iPhone 5 reviews hit, it looked as if Apple's dual-core A6 processor was sporting a clock speed of around 1GHz. We saw reports (and confirmed with our own handset) ranging between 1.00 and 1.02GHz, but a new Geekbench build (v2.3.6) has today revealed a horse of a different color. According to Primate Labs' own John Poole, the latest version of the app -- which landed on the App Store today -- "features a dramatically improved processor frequency detection algorithm, which consistently reports the A6's frequency as 1.3GHz." In speaking with us, he affirmed that "earlier versions of Geekbench had trouble determining the A6's frequency, which lead to people claiming the A6's frequency as 1.0GHz as it was the most common value Geekbench reported." When we asked if he felt that the A6 was capable of dynamically overclocking itself for more demanding tasks, he added: "I don't believe the A6 has any form of processor boost. In our testing, we found the 1.3GHz was constant regardless of whether one core or both cores were busy." Our own in-house iPhone 5 is regularly displaying 1.29GHz, while a tipster's screenshot (hosted after the break) clearly display 1.30GHz. Oh, and if anyone wants to dip their iPhone 5 in a vat of liquid nitrogen while trying to push things well over the 2GHz level, we certainly wouldn't try to dissuade your efforts. [Thanks, Bruno]
iFixit opens up the Apple A6
The ambitious folks at iFixit have looked inside Apple's A6 chip. The gang has teamed up with engineering and analysis firm Chipworks to accomplish the feat and play with some very cool toys. For instance, a bona fide ion blaster was used to remove individual layers from the chip itself. Also, a scanning capacitance microscope was used to reveal the "doping profiles" of NMOS and PMOS devices within the A6. Isn't science fun? You can look at this equipment and read the results over at iFixit.com. Good work, folks!
Apple A6 investigation shows highly customized dual-core, triple-GPU layout
There's been a significant mystery lingering around the A6 processor found in the iPhone 5, even as it became clearer that Apple was veering further than usual from the basic ARM formula. A microscope-level inspection by Chipworks and iFixit is at last identifying the key elements of the 32nm, Samsung-assembled chip and revealing just how far it strays from the beaten path. The examination confirms earlier suspicions of a dual-core design with triple-core graphics -- it's how that design is shaped that makes the difference. Apple chose to lay out the two processor cores by hand rather than let a computer do the work, as most ARM partners do. The procedure is expensive and slow, but also gives the A6 a better-optimized design; it explains why the chip is noticeably faster than much of its competition without needing the brute force approaches of higher clock speeds or extra cores. Some mysteries remain, such as the exact PowerVR graphics that are at work, but it's evident Apple now has the design talent and resources to speed up mobile devices on its own terms rather than wait for off-the-shelf layouts like the Cortex-A15.
How the iPhone 5 got its 'insanely great' A6 processor
It's hard not to be impressed by the A6 engine in the new iPhone 5, since it's now proven to deliver a double-shot of great performance and class-leading battery life. But silicon stories like that don't happen over night or even over the course of a year -- in fact, analyst Linley Gwennap has traced the origins of the A6 all the way back to 2008, when Steve Jobs purchased processor design company P.A. Semi and set one of its teams to work on creating something "insanely great" for mobile devices. Although Apple is steadfastly secretive about its components, Gwennap's history of the A6 (linked below) is both plausible and a straight-up good read for anyone interested in the more fundamental aspects of their gadgets. Whereas the A5 processor stuck closely to ARM's Cortex-A9 design, Gwennap is convinced -- just like Anandtech is --that the A6 treads a very different path: it's still based on ARM's architecture and it's likely fabricated by Samsung using a cutting-edge 32nm process, but it's an in-house vision of what a mobile chip should be. It's the culmination of four years of hard work and perhaps half a billion dollars of investment. That's not to say it's the most powerful chip out there, or even the chip most tailored to its host device -- after all, Samsung also designs great chips for some of its own smartphones. Indeed, Gwennap says that the A6 is probably a dual-core processor that is no more complex than Qualcomm's Snapdragon S4 (let alone the S4 Pro) or the forthcoming generation of Cortex-A15 chips, while its clock speed could be as low as 1.2GHz -- versus a 1.6GHz quad-core Exynos in the Note II and even a 2GHz Intel chip in Motorola's new RAZR i. However, Gwennap predicted that even if the A6 falls short of its rivals "in raw CPU performance," it'd make up for it in terms of low power consumption -- which is precisely what we've confirmed in our review.
iPhone 5 review
Thinner. Lighter. Faster. Simpler. The moment the iPhone 5 was unveiled we knew that it was checking off all the right boxes, folding in all the improvements and refinements people have been demanding over the past year -- yet plenty of folks still went to their respective social networks to type out their bitter disappointment. iPhone upgrade ennui seemed to be sweeping the nation, a sentiment that appeared to quickly dissipate when it came time for people to vote with their wallets. The iPhone 5 is here -- or will be soon, anyway -- and it's every bit the device that people were asking for when the iPhone 4S came out. Its new design has less mass yet leaves room for a larger display and LTE wireless, all while increasing battery life. In nearly every respect, this is an upgrade over the 4S that came before, though it arrives almost a year later than many had hoped. Is it too late to keep pace with the rapidly iterating Android offerings, or is it so good it was worth waiting for? The answer lies below.%Gallery-165757%
Anandtech: Apple iPhone 5 features 1GB of RAM, A6 is a custom SoC
Unsurprisingly, Apple left us in the dark regarding some specifics of the iPhone 5 upon its release. Thankfully, the good folks over at Anandtech have done a bit of digging into those numbers you see bordering Apple's Apple A6 SoC, definitively figuring out that Cupertino's latest phone packs in a total 1GB of Samsung-sourced memory. The site clocks the DRAM inside at 1,066Mhz, noting that it's comprised of "two 512MB dies in a dual-channel LPDDR2 package with 32 bits per channel." Further, Anandtech lists the speed of the iPhone 5's memory at 8,528MB/sec -- an ample 33 percent boost over the 6,400MB/sec rating for the RAM in the iPhone 4S, but well below the 12,800 MB/sec needed to drive the new iPad's bandwidth-hungry screen resolution. Beyond that, the site believes that the A6 is Apple's first truly in-house creation, as it's using math units too new to be found in a ARM Cortex-A9 architecture (like the A5 or A5X) but reportedly isn't a match for the soon-to-be-released Cortex-A15. If true, the implication is significant -- it suggests Apple is taking the more aggressive path of a chip designer like Qualcomm and custom-tailoring large parts of its processor designs to get the speed it wants on a more exacting schedule. That's a quick summation of the details; hit up the source links below if you want the explanation in full geek speak. Jon Fingas contributed to this post.
iPhone 5 hands-on!
At long last, the iPhone 5. We just got our hands on Apple's latest smartphone following its unveiling in San Francisco, and suffice it to say, it's a beautiful thing. Some might say we've been waiting for this moment since October 4th of last year, but another crowd may say that the real next-gen iPhone has been on the burner for much longer. Indeed, this is the first iPhone since June of 2010 to showcase an entirely new design, but it's obvious that Apple's not going to deviate far when it comes to aesthetics. Apple followers will aptly recall Steve Jobs' quote in July of 2010 -- you know, that one about "no one" wanting a big phone, with current CEO Tim Cook seated just feet from Steve as the phrase was uttered. Now, however, Apple's inching ever closer to that very realm, with an elongated 4-inch display that enables new apps to take advantage of more pixels (1,136 x 640), while legacy apps can still operate within a familiar space. The phone itself doesn't feel too much different than the iPhone 4 and 4S; yes, it's a bit taller, but by keeping the width the same, you'll utilize a very familiar grasp to hold it. In typical Apple fashion, even the finest details have been worked over tirelessly. The metal feels downright elegant to the touch, and the same line we've said time and time again applies here: there's no doubting the premium fit and finish when you clutch one of these things. Yeah, the headphone port's now on the bottom, but avid Galaxy Nexus iPod touch users shouldn't have too much trouble adjusting. %Gallery-165125%
Apple introduces A6 processor for the iPhone 5
Apple has announced the next-generation version of its processor for iOS devices. The A6 processor in the iPhone 5 has a two times faster CPU and two times faster graphics. The processor is 22 percent smaller than the A5, and will enable programs such as Pages and Keynote to launch nearly twice as fast. The image processor in the A6 has spatial noise reduction, a smart filter to better handle color-matching, improved low light performance.
Apple: A6 chip in iPhone 5 has 2x CPU power, 2x graphics performance, yet consumes less energy
Every new iPhone needs a new engine, and Tim Cook has just made some bold claims about Apple's latest silicon creation: the A6 processor. He hinted at a significant shrinkage in transistor size, allowing the chip to be 22 percent smaller than the A5 and hence more energy-efficient, while at the same time -- he says -- doubling all-round CPU and graphics capabilities. By way of practical benefits, the Apple CEO promises the Pages app will load up 2.1x faster than before, while Keynote attachments will hit the screen 1.7x faster. At this point we're lacking any further detail about cores or clock speeds or indeed who actually fabricated the A6 (still Samsung, after all that bitterness?), but Apple does tend to be close-lipped on such things. In the meantime, bring on the benchmarks! Check out all the coverage at our iPhone 2012 event hub!
iPhone 5: the rumor roundup
We're on the cusp of Apple's sixth iPhone launch, and there's very different expectations than there were last year. The 2011 rumor cycle left more than a few people burned: the later-than-usual October launch and repeated claims of a heavily-remade design led some to a disappointment when the iPhone 4S arrived, even though the final product had a slew of camera, speed and voice command upgrades. This year, the rumors have been grounded well before there was an event date in our hands. There have been fewer instances of wild rumors. Instead, it's been based more around pragmatism, using either tangible leaks or sources that have a solid track record. Think of the perennial leaks from the Wall Street Journal or the increasingly well-established sourcing from iMore and The Loop. Whether you're conspiracy-minded or not, it's been hard to ignore the sheer number of claims that have tamped down expectations rather than inflated them. It's as though there's a collective fear we'll see a repeat of the 2011 hysteria and deal with fans (or detractors) complaining about missing features that were never promised in the first place. Where last summer was full of uncertainty, this year there's a mounting consensus as to what we'll see, how we'll get it, and when. Tracking everything that's been mentioned may be a handful, however. With that in mind, we'll dive in and gauge what's likely to emerge from behind Apple's curtain on September 12th -- as well as what we can rule out from the get-go.
AMD shows off its first Windows 8 concept tablet, we go hands-on (video)
If Intel and Microsoft have been the royal couple of Computex 2012 (aka the world's biggest Windows 8 Ultrabook tradeshow), AMD has been the third wheel. That doesn't mean it's opted out of the festivities, though. Nope, it's chosen this week to show off its Trinity chips, and it even has its first Windows 8 concept device on display. The reference design, made by Compal, has the same form factor we've seen over and over again this week: an 11.6-inch, 1366 x 768 tablet paired with a keyboard dock. The main differences are that it has a kickstand, and packs one of AMD's Trinity A6 APUs. The chassis is on the chunky side, at a shade under 20mm, and the screen's a fingerprint magnet, but then again, we don't put too much stock in prototype designs; such details are subject to change. Performance seemed smooth so far as we could tell, but then again, we haven't had the chance to put it through its paces, streaming HD video or attempting anything of productive value. We wish we could tell you a bit about rated battery life, but alas, AMD isn't ready to make any public claims just yet. As for the accompanying dock, the keyboard is far more spacious than what we're used to. Want to see it in action? We've got a quick walk-through of the design, with photos and video below.%Gallery-157280%
