Allegations, denials of 'bad' Nvidia chips in MacBook Pros

Bad bumps? A U.K. tech site is alleging that the latest Apple MacBook Pros contain Nvidia graphics chips with the same "bad bumps" problem that Nvidia addressed this summer and said was rectified.

Nvidia said in a phone interview on Tuesday that this is dead wrong.

First a little background. Nvidia issued a statement July 2 saying it would take a charge of up to $200 million to cover repairs due to a "weak die/packaging material set in certain versions of its previous generation GPU and MCP products used in notebook systems."

Broadcom introduces combo 802.11n chip

Broadcom on Monday announced a chip integrating 802.11n Wi-Fi, Bluetooth, and FM radio into a single silicon die, a move designed to expand the range of features available in mid-range mobile-phone handsets.

The introduction of the BCM4329 was motivated in part by the increased popularity of Wi-Fi in mid-range "feature phones," Broadcom said. It added that this growth is due in turn to the integration of cameras, browsers, and audio capabilities into more handsets, which is driving a need for transferring data and media between handsets and other electronics such as TVs, PCs, printers, remote speakers, and … Read more

Forrester Research reduces IT-spending forecast

Growth in information technology spending next year is expected to reach 1.6 percent in the United States, a substantial drop from previous forecasts.

Forrester Research's current 2009 estimate, released on Tuesday, is down from its previous forecast of 6.1 percent growth, which was issued prior to the steep drop in IT spending at the close of the third quarter.

In September, Forrester took the unusual step to update its forecast outside of its usual quarterly schedule, noting that 2009 IT-spending growth would fall to 6.1 percent from previous forecasts of 10 percent growth.

TI, Broadcom add to warnings chorus

In another bad sign for the consumer electronics market, chipmaker Texas Instruments warned that its current quarter sales and earnings will come in far below earlier estimates.

The company said it now expects revenue of $2.3 billion to $2.5 billion, as compared with prior expectations of $2.83 billion to $3.07 billion. Per-share earnings are now seen between 10 cents and 16 cents, as compared with an earlier range of 30 cents to 36 cents.

TI did not provide further details in its press release, but said it would hold a conference call to discuss its finances. … Read more

Intel develops fast, cheap optical links on silicon

Intel is claiming "world record" performance in optical communications using silicon photonics, in a development announced in the journal Nature Photonics.

Silicon photonics-based photo dectors are used to send and receive optical information, particularly in very high-bandwidth applications like supercomputers. Intel says silicon photonics is essential for "ultra-fast transfer of data (in) future computers powered by many processor cores."

The development is significant because it is based on silicon--a readily available, low-cost material used in semicondutor chips today--and outperforms more exotic, pricier materials. To date, Silicon photonics technology, using complementary metal-oxide semiconductor (CMOS) techniques, has suffered … Read more

AMD issues fourth-quarter warning

Advanced Micro Devices warned Thursday its fourth-quarter revenue will come in significantly lower than previously expected, due to weakness across all regions in all its businesses.

AMD shares were climbing back up in the morning, after having dipped to as low as $1.92 just after the markets opened.

The chipmaker said Thursday it expects to post revenue of $1.19 billion in the quarter ending December 27, excluding process technology license revenue. That's 25 percent below its third-quarter performance.

When the company reported its third-quarter revenue of $1.59 billion (excluding the process tech license revenue) in October, … Read more

IPOs a thing of the past?

HALF MOON BAY, Calif.--When bonds are paying yields like stocks and blue-chip companies are severely undervalued, who wants to invest in equities, let alone an IPO?

Those are just some of the challenges companies face in attracting investors in this current economic climate, noted panelists Tuesday during the AlwaysOn Venture Summit West conference here.

Despite the dire economic climate and the market meltdown, the panelists noted "good companies" will still have an opportunity to go public--it just may take longer.

Investors, such as mutual funds, asset managers, pension funds and hedge funds, are holding a significant amount … Read more

Intel rethinks Netbooks: 'Fine for an hour' but...

The Netbook, take two: When Advanced Micro Devices said it wasn't going to focus on Netbooks, as Intel and its partners defined them, maybe it was on to something.

Intel is re-evaluating the Netbook market as possibly not The Next Big Thing. This from the company that makes the Atom processor and accompanying silicon that go into most of the Netbooks sold today.

At a recent Raymond James IT Supply Chain Conference (streamed via this Intel page), Stu Pann, vice president in the sales and marketing group at Intel, said his company sees the Netbook differently now.

"We … Read more

Micron readies 256GB solid-state drive

Micron Technology will bring out a 256GB solid-state drive early next year while it moves, along with Intel, to a new manufacturing process.

A Micron representative said Monday that the company will start volume production of a 256GB solid-state drive for consumer use in March 2009.

This follows Samsung's announcement last week that it had begun mass-producing 256GB solid-state drives.

The Micron RealSSD C200 will read data at 250MBps (megabytes per second) and write at 100MBps. It is sampling to customers now. Samsung, by comparison, is claiming sequential read rates of 220MBps, with sequential write rates of 200MBps.
