This could be nifty.

Graphics chip maker Nvidia on Friday announced seven new GeForce 400M series graphics cards for notebooks, which could provide parallel-processing capabilities to accelerate Web browsing and 3D image rendering.

Per Macworld, Microsoft’s Internet Explorer, Mozilla’s Firefox and Google’s Chrome have either implemented or will soon include the capability to offload tasks like rendering of HTML 5 or Flash video content to graphics processors. Nvidia’s new GeForce graphics cards will be faster at processing those tasks than CPUs, which should make Web browsing snappier.

The new graphics cards will be around 40% faster than the earlier 300M series at execution of tasks, said Ken Brown, an Nvidia spokesman.

While the CPU remains at the center of running tasks, developers are writing applications to harness the parallel-processing capabilities of graphics processors to speed up applications, said Dean McCarron, principal analyst at Mercury Research.

“That’s one of the changes with the new browsers, is they support that capability,” McCarron said.

Notebooks with Intel’s latest Core processors already have a graphics processor integrated in one chip next to the CPU. However, discrete GPUs have a faster and wider pipe to run applications, McCarron said.

Still, graphics processors can draw more power than CPUs or integrated graphics, which can affect battery life of notebooks. Nvidia’s graphics cards support new switchable technology called Optimus, where specific tasks like video rendering can be seamlessly switched between the CPU and GPU. The GPU kicks in only when needed, preserving the notebook’s battery life.

Nvidia declined to comment on the exact power drawn by the new graphics cards, citing company policy. In recent years the company has taken charges for faulty dies and weak packaging material used in its graphics chips that led to notebooks overheating. Those issues have been resolved for a while, Brown said.

“Nvidia GPUs are made with a different manufacturing substrate to prevent chips from experiencing thermal issues over time. Our GPUs run in the tolerance level of their specification and the notebook chassis design constraints,” Brown said.

More laptops are shipping with discrete GPUs as users look for stronger multimedia capabilities, McCarron said. Nvidia will be trying to extend its presence in the market with the new products, and it will have to compete with rival Advanced Micro Devices, which already offers Radeon HD notebook graphics cards.

Beyond Web browsing, the graphics cards will provide a better gaming experience and bring Blu-ray 3D movie playback to laptops, Nvidia’s Brown said. The graphics cards will support DirectX 11, Microsoft’s latest graphics technology included in the Windows 7 OS.

The new offerings include the GeForce GT 415M, GT 420M, GT 425M, GT 435M, GT 445M, and the faster GTX 460M and GTX 470M graphics cards. The cards will be available only through the PC makers, and Nvidia did not comment on when the notebooks would become available. The graphics cards will be offered through PC makers including Acer, Asus, Dell, Lenovo, Samsung and Toshiba.

Individual pricing for the graphics cards and whether or not the cards would eventually find their way to Apple’s notebook products were not disclosed.

AMD to consolidate graphics chips, retire ATI brand name

AMD, the current exclusive provider of discrete graphics chips in Apple’s latest refresh of the Mac desktop lineup, will phase out the ATI graphics brand name this year.

Per ZDnet, AMD is prepared to make the change because it believes having two brands is unnecessary, and the company plans to offer both CPUs and GPUs combined in its forthcoming Fusion product. Existing products such as the Radeon chip series will maintain their names, but will be labeled as AMD products rather than ATI.

AMD said it conducted research that found its brand is stronger than ATI, and that consumer preference toward ATI triples when they are aware of the ATI-AMD merger. AMD acquired ATI for US$5.4 billion in 2006.

Apple partners with AMD’s rival, Intel, for all of the CPUs in its line of Macs. However, AMD and Apple do have a close relationship when it comes to graphics processing in the Mac lineup.

In July, Apple updated its Mac Pro and iMac desktops, and the new machines only offer ATI graphics. But soon, those same products will be labeled AMD.

AMD, in justifying the change, highlighted its relationship with Apple, noting that the company continues to “secure new design wins with major OEMs — e.g. Apple iMac and Mac Pro.” The company said it has the “momentum and data to make this change with confidence.”

The chipmaker also said that with the AMD Fusion chip set to debut in the fourth quarter of 2010, it is “perfect timing” for the branding change. AMD said its “Ontario” model, which will be its first to offer a CPU and GPU in a combined package, will be a “watershed moment” for the company.

Not the worst thing in the world, even though as a Mac gamer I fondly remember drooling over the coolest ATI graphics cards in yesteryear’s Power Mac G3 and G4 units…

It’s hard to say when this might find its way into an Apple notebook, but it could be amazing when it does.

Processor giant Intel announced that its next-generation laptop chips will have a dozen new features to improve graphics performance and will be able to play Blu-ray 3D movies, the company said on Thursday.

Laptops with processors based on the Sandy Bridge architecture will play Blu-ray 3D movies while preserving battery life, said Nick Knupffer, an Intel spokesman. Users won’t need to buy a separate graphics processor to specifically view 3D content.

Sandy Bridge chips are due to go into production later this year, Knupffer said. Company officials have said that PCs with the new chips could hit store shelves in the first half of next year.

Per Macworld, the company is expected to shed more light on Sandy Bridge’s graphics performance at the upcoming Intel Developer Forum in San Francisco from September 13th through the 15th.

Intel for the first time will integrate the CPU and graphics processor on a single chip, said Nathan Brookwood, principal analyst at Insight 64. The current generation of chips based on the Westmere architecture have the CPU and graphics core on one piece of silicon, but as separate units.

The higher levels of integration will also help Intel include additional transistors to improve graphics performance, Brookwood said. The Sandy Bridge CPUs and GPUs will be made using the 32-nanometer process, while with current chips, the CPU and GPU are made using the 32-nm process and the 45-nm process, respectively.

Graphics performance typically doubles from one chip generation to the next, said Dean McCarron, principal analyst at Mercury Research.

Intel’s current laptop chips are capable of 1080p video, and improvements in Sandy Bridge chips could bring a noticeable graphics improvement to PCs, McCarron said.

Now it remains to be seen what Apple has to say about Blu-Ray support and how this might be integrated into future generations of Apple laptops…

Apple purchased of chip maker Intrinsity confirmed

Late Tuesday, the New York Times confirmed a rumor that Apple had purchased Intrinsity, a privately owned ARM chip design firm.

Citing “people familiar with the deal,” the report also included an estimated US$121 million purchase price, provided by Tom R. Halfill, an analyst with Microprocessor Report.

Apple spokesman Steve Dowling indirectly confirmed the purchase, stating that the the hardware maker “buys smaller technology companies from time to time.” However, he added that Apple does not reveal “purpose or plans” with any acquisition.

Sources close to the story also confirmed to the Times that Intrinsity helped to design the custom A4 processor found in the recently released iPad. Weeks ago, one analyst suggested that only Intrinsity could have delivered the A4 processor with its snappy 1GHz clock speed. The Cortex-A8 reference design on which the A4 is based can only be clocked up to 650MHz.

In early April, rumors first surfaced that Apple purchased Intrinsity to help build the A4 chip. Evidence to support the acquisition surfaced when a number of Intrinsity employees changed their company status on LinkedIn to Apple on the first of the month.

The purchase follows similar acquisitions and in 2008, Apple also bought fabless chip designer P.A. Semi for US$278 million in 2008.

Apple also bought a 3% stake in 2008 in Imagination Technologies, maker of the PowerVR mobile graphics chip found in the company’s mobile devices, including the iPhone. Last year, Apple bumped its share to 9.5%. In addition to partnering with Apple, Imagination also competes with ARM Holdings, which makes the reference designs for chips that power the iPhone, iPod touch and iPad.

Intel this week previewed its 32 nanometer Core i7-980X processor, a six-core CPU known as “Gulftown” and fueled rumors that the CPU could make its way to Apple’s Mac Pro line as early as March 15th.

Per ZDnet, tips have been received from sources close to the store stating that the hexacore processor could be just around the corner.

“If you’re thinking of buying a Mac Pro, you might want to wait a few days,” wrote Adrian Kingsley-Hughes.

The new processor carries a speed of 3.33GHz, six cores capable of 12 threads, and 130W thermal design power. He also noted that he’s heard no reports of impending changes to the MacBook Pro line.

The new six-core Mac Pro with the Core i7-980X has been rumored for months, with the chip set to arrive on the open market sometime this month. The new 32 nanometer chips feature 12MB of L3 cache. Apple usually doubles the processors in its high-end professional workstations, so it’s possible the new Mac Pro system could have a total of 12 cores and 24 threads.

The “Gulftown” processor will be sold under the Intel Core i9 name, while the server version, which has been adopted by Apple in the past, will fall under the Xeon 5600 series.

The last major refresh to the Mac Pro equipped it with its Nehalem Xeon processors, with a high-end eight-core Mac Pro offering two 2.26GHz Quad-Core Intel Xeon 5500 chips. Last year, Apple quietly upgraded that to a potential maximum 2.93GHz eight-core system.

There’s a new wave of MacBook notebooks en route.

And it may arrive sooner rather than later.

Per Canadian web site, Geekbench, a recent set of test appears to have show an unreleased Arrandale MacBook Pro notebook running at 2.66 GHz according to MacRumors.

The processor shown is listed as an Intel Core i7 M 620 running at 2.66GHz with a Turbo frequency up to 3.33 GHz. The Intel Core i7 M 620 functions as a high end dual core processor with Turbo Boost and Hyperthreading features.

The MacBook Pro model designation is listed as “6,1″ and has a non-shipping build of Mac OS X 10.6.2 (Build 10C3067).

The original article reports that supplies of MacBooks have been constrained according to international resellers, adding to the belief new Apple laptops are forthcoming.

Intel officially unveiled the Core i3, i5 and i7 processors at last month’s CES trade show in Las Vegas.

The new chips fall under the brands of Core i3 for low-end systems, Core i5 for midrange systems and Core i7 for the fastest systems.

The new processors include dual-core laptop chips under the three brands running between 1.06GHz and 2.66GHz, and desktop chips running between 2.93GHz and 3.46GHz.

According to Intel, the Intel Core i5 processor features: “4-way multi-task processing that allows each core of your processor to work on two tasks at the same time, delivering the performance you need for smart multitasking.”

Last month, Intel pulled an internal ad showing a MacBook running with the Core i5 processor. The MacBook was being offered as a prize as part of the Intel Retail Edge Program, and was sent out in promotional emails. The ad was later replaced with one offering an HP Envy laptop as a replacement.

Initial reports about the iPad are coming back and the general consensus seems to agree that the thing is fairly speedy.

Per Macworld UK, the 1GHz A4 chip found in the iPad could ultimately find its way into the iPhone, as both the A4 and the current iPhone processors are designed around a low-power scheme as well as designed to run the iPhone OS.

The A4 chip was designed for portable products, and modified chips based on the architecture are prime candidates to be used in new iPhone versions, said Nathan Brookwood, principal analyst at Insight 64. A variant of the A4 chip could make iPhones much faster, he said.

“There’s really no reason why a chip with this kind of characteristic wouldn’t make it in the iPhone,” Brookwood said.

“My guess is [the A4] is a lot faster than what they use in existing products,” Brookwood said.

An Apple representative declined to provide details about the A4 chip on Wednesday, but analysts said it was based on an Arm processor core. The chip was most likely designed by employees who came with Apple’s 2008 acquisition of chip firm PA Semi, which earlier was involved in designing low-power chips.

If you’re currently hankering for a forthcoming MacBook Pro featuring Intel’s new Core i5 processor, it may be en route.

Per AppleInsider, an e-mail promotion sent from Intel to members of Intel’s Retail Edge promotional program highlight a forthcoming MacBook Pro from Apple sporting the Core processor.

The promotion was included in an e-mail sent out to U.S. members of the Intel Retail Edge Program. It reads: “January Prize Draw: Win a MacBook Pro. Pass this month’s trainings for 2 chances to win one of 2 MacBook Pro laptops with the accelerated response of an Intel Core i5 processor.”

Currently, the top MacBook Pro features an Intel Core 2 Duo processor.

The Intel Retail Edge Program allows retail employees who sell Intel products to access technical knowledge and sales tips, which allows them to earn “chips” which can be exchanged for products. The program also offers occasional contests and giveaways.

Last week at CES, Intel formally introduced its new line of processors, which included the new Core i3, i5 and i7 chips. The mobile Core i5 is considered to be a likely candidate for a coming MacBook Pro refresh.

Apple is expected to host an event Jan. 27 at the Yerba Buena Center for the Arts in San Francisco to introduce new products. While most speculation has centered around a tablet being unveiled at the event, Apple could also use it as an opportunity to refresh its MacBook Pro line.

Over at CES, Intel released its next generation of processors under the Core i3 brand for low end systems, the Core i5 brand for midrange systems and the Core i7 brand for the fastest systems. The new processors include dual-core laptop chips under the three brands running between 1.06GHz and 2.66GHz, and desktop chips running between 2.93GHz and 3.46GHz.

Per Macworld UK, the new chips are manufactured using the 32-nanometer process, which makes them smaller and more power-efficient than earlier chips. Based on the Westmere architecture, the transistors are a step away from chips manufactured using the 45-nanometer process.

Intel will announce quad-core chips and low-voltage processors based on the architecture later this year, said Sean Maloney, executive vice president at Intel, during a press conference.

Compared to previous generations of processors, the new processors speed up high-end tasks like intense graphics as well as mundane tasks like syncing a music player, Maloney said. Related tasks would run close to two times faster than previous chips.

Intel has also integrated graphics chips into the new processor package, which could make the chips capable of playing Blu-ray movies or high-definition games.

But the graphics processors have some limitations. “It doesn’t go into the high end… you always get a big fat graphics chip with a heat sink on it,” Maloney said.

Laptop responsiveness will also improve with the Turbo Boost mode, which can crank up the speed of cores to boost performance. The technology can also shut down cores when not needed to save power.

Intel launched three Core i3, eight Core i5, and five Core i7 processors for laptops and desktops. Maloney went on to state that there are presently 500 designs based on the new chips and that the chips are available immediately, and many desktops and laptops were on show on the CES show floor at Intel’s booth.

The laptop processors include five Core-i7 chips, including the 620M chip that runs at 2.66GHz and is priced at US$332 for 1,000 units. The slowest chip is the low-power 620UM chip, which runs at 1.06GHz and is priced at US$278. Two Core i3 chip were listed for laptops, including the i3-350M, which runs at 2.26GHz.

The chip’s price was not immediately available. Four Core i5 chips for laptops were also listed, including the Corei5-540M, which runs at up to 2.53GHz and is priced at US$257. A Core i5-520UM low-power chip runs at 1.06GHz and is priced at US$241.

The new desktop processors include two Core i5 and two Core i3 chips. The fastest Core i5 chip is the Core i5-670, which runs at 3.46GHz and is priced at US$284. The fastest Core i3 chips is the Core i3-540, which runs at 3.06GHz and is priced at US$133.

Westmere is based on the underpinnings of the Nehalem architecture, which itself included new features included an integrated memory controllers. Nehalem chips were manufactured using the 45-nm process and introduced late last year.

No official word has been released as to which processors will find their way into future Apple products.
