30 Years of Personal Computer Market Share Figures

It's been a long, strange trip for the personal computer over 30 years. Ars takes a look back at the comings and goings of players in the PC market, from Altair to Zeta OS, to see how we got where we are today. "When you step back and look at the big picture, the overall dominance of the PC becomes clear. However, this was not always the case, and in fact it wasn't until 1986 that the PC platform first surpassed 50% market share. This was more than a decade after the first personal computer was sold."

Dual-Core Processing Explained

"With the recent introduction of dual-core processors come more questions about system performance. Does a dual-core computer really perform better than a single-core CPU? How does it compare to a true multi-CPU system? What about Hyper-Threading Technology -- is it a thing of the past? Read on for an explanation of dual-core processors and symmetric multiprocessing and what it means to your computing experience."

Intel, AMD Believe in the Power of Four

The race is on to produce four-core processors for PCs. Intel, which is readying a bevy of dual-core chips for release in systems in the next month, is already plotting a move to quad cores, which some reports have said could come as soon as early 2007. AMD has already discussed a plan to begin offering a family of four-core chips in 2007, whereas Intel has only hinted about a four- core server chip thus far.

Dual-Core Chips: AMD Smashes Intel

"After reading the round-by-round account of our dual-core desktop CPU prizefight, it should come as no shock that AMD's Athlon 64 X2 chips are the runaway victors here, laying out the Intel Pentium D and Pentium Extreme Edition 840 chips pins up. If we had to call out one chip, AMD's Athlon 64 X2 4400+ is an outstanding bargain given the competition, but as our results show, any AMD dual-core CPU will serve you better than its similarly priced Intel equivalent."

Maxell To Offer 300GB Holographic Discs ‘Late 2006’

Maxell will ship its first holographic storage system late next year, the company has pledged. The storage specialist will initially offer a removable system based on 300GB media and capable of transfering data at a rate of 20MBps, Maxell said. However, the company said the technology, designed by InPhase Technologies, is capable of achieving 1.6TB per disk - and that's uncompressed capacity - with a 120MBps bandwidth.

100 USD Laptop Documentary

Here is an 8 minute documentary about the recently unveiled 100$ laptop. It shows the laptop in action, and also discusses its aspects with one of the team members, such as the screen, the cheap keyboard, and much more. The video is in Quicktime, and this mirror gives better performance. My take: I am very, very, very impressed. The thought put into the details is just stunning. Every aspect of this machine has a function. Just astonishing.

Motive Behind the $100 Notebook: Profits

"If you shop around, you can actually get a functional computer for $500 (EUR 425,-). But as we become more budget conscious, $500 seems to be a bit much for a standard machine, so what's our next target? Why, it's an over ambitious $100 (EUR 85,-) notebook. How companies accomplish this is their business; what we are interested in is what they ship out for a product when all is said and done. As of now, however, there is one thing that interests me even more, and that is, why would they want to sell me a $100 notebook in the first place?"

$100 Laptop by MIT Unveiled in Tunisia

MIT has unveiled its $100 hand-cranked laptop computer to the United Nations technology summit in Tunisia and said that it hopes to make millions of the devices to give to the poorest people in the world. The lime-green machines, which are about the size of a text book, will offer wireless connectivity via a mesh network of their own creation allowing peer-to-peer communication and operate in areas without a reliable electricity supply.

IBM Releases Cell BE Technology

The Cell Broadband Engine is a breakthrough microprocessor with unique capabilities for applications requiring video, 3D graphics, or high-performance computation for imaging, security, visualization, healthcare, surveillance and more. The following technologies are from the CBE Software Development Kit v1.0 that provides everything Cell software developers need to create, build, simulate, and test Cell applications.

Details on Power Saving in the 970MP; Fujitsu’s 4-Core 2.7Ghz SPARC

Some newsbits from the world of processors. First, IBM detailed power-saving techniques in the new PowerPC 907MP (the dual-core G5). Secondly, "Fujitsu's Sparc64 VI+ processor, code-named Jupiter and due for release in 2008, is a four-core processor with clock speeds of at least 2.7GHz, the company said Tuesday." And to complement today's batch of processor news, IBM unveiled the Xbox 360 processor.

Startup Puts a Twist on PowerPC

P.A. Semi, a 150-employee chip startup, wants to make name for itself through attention to detail. The Silicon Valley chip startup, run by chip legend Dan Dobberpuhl-Dobberpuhl, its CEO, presided over the development of the Alpha processor while at Digital Equipment Corp. lifted its veil of secrecy Monday. The company will begin offering a new family of low-power, multicore, PowerPC architecture processors in 2006.

The Mini-ITX Project Revisited

"Once my original Mini-ITX project was completed I finally had a chance to sit back and use the computer. Knowing how simple my needs were, the Mini-ITX project computer was orginally designed to be as basic and quiet as possible. This meant no hard drive, no extra accessories- just a stripped down system. While this suited my needs well at the time, its lack of versatility soon became an issue. This meant it was back to the drawing board for a retooling of the Mini-ITX project computer."
