Core Values: The silicon behind Android

by Anand Shimpi posted Oct 14th 2009 at 3:30PM

Core Values is our new monthly column from Anand Shimpi, Editor-in-chief of AnandTech. With over a decade of experience poring over the latest in chip developments, he's here to explain how things work and why our tech is the way it is.

Remember this chart? It's interesting for a number of reasons, but I want to highlight that all present day Android phones use virtually the same Qualcomm application processor, all based on a sluggish 528MHz ARM11 core. Blech.

I've got nothing against Qualcomm, but a big reason most Android phones feel slow is because they're running on slow hardware. The ARM11 core was first announced in 2003. It's old and creaky, and it's used so frequently because it's cheap. But the basic rules of chip design mean that things are about to change fast.

Intel begins production of 32nm Westmere processors

by Tim Stevens posted Sep 14th 2009 at 8:03AM

Were you so impressed by the reviews of Intel's latest Lynfield Core i7 chips that you ran out and paid the early-adopter premium to buy one? Your period of superiority hasn't lasted long, dear reader, with the company announcing initial production of 32nm processors has begun. It's taken many years (and a $7 billion manufacturing investment) to get these Westmere chips onto silicon, with the Clarkdale (desktop) and Arrandale (notebook) lines expected to start showing up in over-sized cardboard boxes before the end of the year. What's next for 45nm chips, like those new Lynnfields? A slow fade to obsolescence, as they're likely to be the last of the breed -- but they at least can take pride in knowing they were the king of their class; a class that resulted in a whopping 200 million sales. Check out the video after the break for a some silicon and cleanroom action.

Seven Samurai chipmakers set to take on Intel

by Joseph L. Flatley posted Sep 4th 2009 at 3:58PM

You know, it's been nearly forty years since Intel introduced the first microprocessor, and even at this late date the company comprises a whopping eighty percent of the global market for CPUs. But not so fast! Like an electronics industry remake of The Magnificent Seven (which is, of course, an American remake of The Seven Samurai) NEC and Renesas have teamed up with a stalwart band of companies, including Hitachi, Toshiba, Fujitsu, Panasonic, and Canon, to develop a new CPU that is compatible with Waseda University professor Hironori Kasahara's "innovative energy-saving software." The goal is to create a commercial processor that runs on solar cells, moderates power use according to the amount of data being processed (a current prototype runs on 30% the power of a standard CPU), remains on even when mains power is cut, and, of course, upsets the apple cart over at Intel. Once a standard is adopted and the chip is used in a wide range of electronics, firms will be able to realize massive savings on software development. The new format is expected to to be in place by the end of 2012. [Warning: Read link requires subscription]

Movie Gadget Friday: Weird Science

by Ariel Waldman posted Aug 28th 2009 at 3:31PM

Ariel Waldman contributes Movie Gadget Friday, where she highlights the lovable and lame gadgets from the world of cinema.

We last left off on the cyberpunk streets of LA in Strange Days. This week, in honor of the loss of the man behind so many 1980's icons, Movie Gadget Friday is paying homage to filmmaker John Hughes with a look into the 1985 cult-classic Weird Science. Tapping into the geek-fiction fantasies of most tinkering teenagers, real-life gadget specs are stretched to surreal capabilities to create the ultimate female bombshell. It's without surprise that the character's name, Lisa, was inspired by the Apple Lisa, Apple's first GUI computer.

IBM brings the ruckus -- and new Power7 processor

by Vladislav Savov posted Aug 26th 2009 at 10:45AM

IBM likes its servers and supercomputers. A lot. After giving the Power6 plenty of self-congratulatory publicity, Big Blue is ready to move on to the 7th generation of Power, which is set to be announced at the Hot Chips conference this evening. With eight cores and up to four SMT4 threads running on each, the 45nm Power7 can perform 32 simultaneous tasks per chip. The designers have slapped in a whopping 32MB of eDRAM in each chip for improved latency, dual DDR3 memory controllers for a sustained 100GB per second bandwidth, and even error correcting code and memory mirroring for redundancy. Sounds like a major boon for research into the brains of mice and the history of dirty words, but we don't expect to hear much about this proc outside the server farm.

AMD's 3.4GHz Phenom II X4 965 Black Edition review roundup: fast, but not Intel fast

by Darren Murph posted Aug 13th 2009 at 12:32AM

Say what you will about AMD, but don't you dare call it lazy. Within a matter of weeks, the outfit has launched a 2GB FirePro for um, pros, a 785G integrated chip for laypeople and now a new Phenom II X4 for the gamers in attendance. The all new Phenom II X4 965 Black Edition is the "highest clocked quad-core processor for desktop PCs," checking in with a stock frequency of 3.4GHz and support for DDR3 and AMD OverDrive 3.0. Based on the Dragon platform, the chip is actually identical to the 955 it replaces at the top save for the clock speed, and during the collective web's testing, it easily outpaced every other AMD option out there. Unfortunately, it still couldn't put the hurt on a smattering of Intel chips, with the Core 2 Extreme QX9770 and Core i7 920 besting it in all but a few tests. All told, the chip was found to be an incremental (albeit fun) update, but given that it's currently priced between Intel's Core 2 Quad Q9550 ($219) and the aforesaid Core i7 920 ($279), it's not a clear-cut bargain at $245. Still, give it a lil' shelf time, let the MSRP sink and it just might be worth another look in due time.

AMD parties hard after shipping 500 millionth x86 processor

by Darren Murph posted Jul 24th 2009 at 2:18AM

Get on down with your bad self, Mr. Spaceman -- AMD just shipped its 500 millionth x86 processor! Shortly after the company celebrated 40 years of hanging tough and doing its best to overtake Intel, the outfit has now revealed that a half billion x86 CPUs have left its facilities over the past two score. We pinged Intel in order to find out just how that number stacked up, but all we were told is that the 500 million milestone was celebrated awhile back down in Santa Clara. We'll just chalk the vagueness up to Intel not wanting to spoil an otherwise raucous Silicon Valley shindig. Classy.

Intel applies "stars" ratings to processors, processors lose self-esteem

by Donald Melanson posted Apr 10th 2009 at 3:14PM

It looks like those confused by the multitude of Intel processors out there needn't linger in indecision any longer, as Intel itself has now come up with a new scheme that it hopes will help simplify the buying process significantly. As you can see above, that consists of a new rating system that gives processors between one and five stars, which Intel says indicates "relative performance, not a price-performance type of thing." As you might expect, the five-star rating is reserved for the like of the Core i7 and Core i7 Extreme, with the one-star ranks apparently occupied solely by various Celeron processors -- the Atom, it seems, is in a class all its own. Somewhat less notably, Intel has also taken the opportunity to roll out some spruced processor logos, which should already be showing themselves in stores along with displays featuring the new star rating system.

Intel Core 2 Quad S-Series shaves power consumption to 65W

by Darren Murph posted Mar 29th 2009 at 10:44AM

In a relatively hush-hush manner, Intel recently slipped out energy saving versions of its Core 2 Quad Q8200, Q9400 and Q9550 CPUs, all of which are suffixed with a simple "s." Put simply, these S-Series chips are built using the same 45 nanometer process technology as used on the regular models, and aside from TDP, all the specifications are exactly alike. The difference comes in power consumption, as the S crew sucks down just 65 watts compared to 95 watts in the standard issue models. Tom's Hardware had a chance to handle, benchmark and report on these new power sippers, and lucky for you, they found performance to be equal to that of the higher power chips. Granted, you'll have to pony up a few extra bucks in order to treat Mother Earth (and your energy bill) better, but at least we're working down the power ladder instead of the other way around.

AMD nets final approval to create The Foundry Company

by Darren Murph posted Feb 19th 2009 at 10:34AM

After having to delay the final vote earlier this month due to a lack of participation (d'oh!), AMD has dotted the final 'i' in its attempt to spin off semiconductor manufacturing. Said company, along with the Advanced Technology Investment Company, have now secured the final approval necessary to create The Foundry Company. Stockholder approval was the only remaining hurdle to be jumped, and the joint venture transaction is expected to fully close by March 2nd of this year. By the numbers, AMD stockholders approved a proposal to issue 58 million shares of its common stock along with warrants to purchase 35 million shares of its common stock and 35 million shares of the company's common stock upon exercise of those warrants to an affiliate of the Mubadala Development Company PJSC (perplexing, we know). Now, let's see if AMD can keep up with Intel's own $7 billion investment.

Integrated circuit turns 50, now isn't that nifty?

by Darren Murph posted Sep 13th 2008 at 10:17AM

Hard to believe that Jack Kilby's unsightly concoction (pictured above) turned 50 yesterday, but it's true. Half a century ago, Mr. Kilby crafted the integrated circuit, which ended up having a monumental impact on taking computers from warehouse-sized to, well, not-warehouse-sized. As the story goes, the very first microchip was demonstrated on the 12th of September in 1958, and it passed its first test: "producing a sine wave on an oscilloscope screen." Safe to say we all know how things progressed from there. Here's to you, IC -- and here's to 50 more.

Texas Instruments gets excited about energy scavenging

by Darren Murph posted Aug 25th 2008 at 8:01AM

Texas Instruments has a lot to do with the original microchip, if for no other reason than being the employer of inventor Jack Kilby. Now, however, TI is looking to produce chips and other related gizmos that require an infinitesimally small amount of energy to operate. The overriding theme guiding the engineers is "energy scavenging," which alludes to grasping power from even the most unlikely of places -- vibrations from a bridge as cars pass over, capturing wasted exhaust from a car or bottling up all that frustration your sibling shows when you own him / her again in Super Smash Bros. Brawl. The possibilities are just about endless, with networked battery-free smoke alarms, solar-powered mobiles and gaming laptops that feed off of extraordinarily focused brain waves in the mix. Okay, so that last one is still eons from reality, but at least we're headed in that direction.

Intel's dual-core Atom 330 processor to ship in Q4 2008

by Darren Murph posted Jul 24th 2008 at 6:14PM

Bad news, Atom fans. That dual-core nugget of netbook-powering goodness that you were so looking forward to seeing in Q3 won't begin shipping until Q4. According to some data picked up by Fudzilla, the Atom 330 will only be debuting in Q3 (September 21st, to be precise), but it isn't scheduled to get a shipping label until a few months later. Also of note, we're told that the chip will sell (at some place in the supply chain) for $43, but don't count on those savings being completely passed onto you.

Microchip breakthrough could keep Moore's law intact (again)

by Darren Murph posted Jul 11th 2008 at 11:52AM

We're pretty certain we'll be hearing this same story each year, every year for the rest of eternity, but hey, not like we're kvetching over that or anything. Once again, we're hearing that mad scientists have developed a breakthrough that makes Mr. Moore look remarkably bright, as a new approach to chip making could carve features in silicon chips "that are many times smaller than the wavelength of the light used to make them." Reportedly, the new method "produces grids of parallel lines just 25-nanometers wide using light with a wavelength of 351-nanometers," although the grids aren't functional circuits just yet. If you're interested in more technobabble on the matter, head on down to the read link, but we'd recommend against if you're easily frightened by terms like "photolithographic" and "nanotechnology."

Atom processor to cost Intel just $6 to $8?

by Darren Murph posted Mar 30th 2008 at 5:46AM

Ever since Intel compared the criticality of its (still) forthcoming Silverthorne (which now goes by Atom, if you couldn't guess) processor to the original Pentium last June, we've all wondered just how fantasmical our worlds would become when this thing finally dropped. Now, however, Tom's Hardware has discovered that the release may actually do more for Intel than we geeks. After consulting a source it believes to be quite credible, it found that the CPU -- which will likely sell for upwards of $30 at the low-end -- will cost Intel just "$6 to $8, including production, packaging and shipping." Without busting out the abacus, it's still fairly easy to see how profitable said chips could be if Intel can move these at even a snail's pace, but of course, we'd take the dollars and cents estimates with a grain of salt until they actually hit the market.
