Liquid cooling for MacBooks?

Found this while searching for some stuff on my desktop.

Apple is considering using liquid coolant to keep the temperature down on future MacBooks and other devices.

This is not the first time apple have tried this. In 2004 their PowerMac G5s came with liquid cooling, but this was short lived as the system was prone leaks. Apple ended up replacing many units claiming full responsibility.

Apple states...

"AI puts a significant increase in the computational performance of electronic devices of the past few years has made it harder to maintain acceptable internal and external operational temperatures in those devices."

We all know laptops are a lot harder to keep cool, especially with the performance that end users require, while still wanting to stay portable.
The blueprints are impressive. But I hope that Apple have learnt from their mistakes 4 years ago. None of us will want coolant to leak all over the guts of our computer and desk.





















This is all just theory for now, but you may be hearing more about this soon.

Sony Beta Launches “Home” for PlayStation 3 Owners

Sony Computer Entertainment Inc. (SCEI) has announced that its PlayStation Home Beta service for PlayStation 3 video game console will become available for all PS3 users around the world. Following the successful completion of the closed beta service, PlayStation Home’s open beta service will continue to evolve with new features and functionality.

“PlayStation Home is truly a promising network community service on the PlayStation platform, made possible with the powerful combination of PS3’s overwhelming computational power and PlayStation Network that covers many countries around the globe,” said Kazuo Hirai, president and group chief executive officer of SCEI.

PlayStation Home is a 3D social gaming community available on PlayStation 3 that allows users to interact, communicate and share gaming or even movie experiences. Within PlayStation Home, users can create and customize their own unique avatars and explore virtual community in real time where they can communicate freely through text or voice chat. PlayStation Home users will not only be able to enjoy variety of entertainment content such as mini-games, videos and special events along with their friends, but will also be able to create their own community by using the “Club 2” feature to create clubs with other PlayStation Home users who share the same interests. Sony's Home has no analogues on competing new-generation video-game consoles - Microsoft Xbox 360 and Nintendo Wii.

PlayStation Home is available as a free download and will launch directly from the PlayStation Home icon on the PlayStation Network column of XMB (XrossMediaBar) on the PS3. Users will be able to experience basic features and services of PlayStation Home, free of charge.

Sony promises that PlayStation Home will allow open interaction among users, business partners and SCEI, and will evolve with additional features including dedicated game spaces, special events and exclusive themed items.

“We are committed to providing PS3 users with exciting gaming experiences with PlayStation Home and together with our partners and users, expand the new world of interactive entertainment as we move forward,” Mr. Hirai added.

XFX Plans to Start Selling ATI Radeon Graphics Cards

XFX, a division of Pine Technologies, will reportedly cease exclusive sales of Nvidia-branded graphics cards and will start shipping products based on ATI Radeon HD graphics processing units (GPUs). If the information is correct, then it emphasizes that market positions of ATI, graphics product group of Advanced Micro Devices, are improving.

XFX will bring to market a range of ATI Radeon HD graphics cards early in 2009, according to a news-story at Hexus.net web-site. It remains to be seen whether XFX will bring to market its well-known heavily factory-overclocked XXX-edition ATI Radeon HD graphics cards, or will only offer standard products only. It is reported that the formal announcement will be made on Tuesday, December 16, 2008.

Even though the market share of XFX is hardly high, it is a rather popular brand name among enthusiasts that can further popularize ATI Radeon brand among gamers. Moreover, if XFX brings substantially faster Radeon graphics cards to market, they will pressure a lot of pre-overclocked Nvidia GeForce adapters that are available widely.

In fact, XFX has dropped exclusive usage of Nvidia GeForce and Nvidia nForce chips on its products with the release of Intel chipset based mainboards. The company currently ships at least one Intel G31-based mainboard and it is highly likely that the range will be expanded along with the expansion of XFX’s motherboard business.

A number of Nvidia Corp.'s partners have decided to drop exlusivity to the company in the recent months after ATI unveiled its Radeon HD 4800-series GPUs. Nevertheless, in Q3 2008 Nvidia commanded 60% of the market of standalone graphics chips for desktop computers. At present Nvidia still has a number of partners who maintains exclusive sales of Nvidia GeForce graphics cards, including BFG Technologies, EVGA Corp. and Leadtek Research.

XFX and ATI/AMD did not comment on the news-story.

Super Talent Announces Highest-Speed Solid-State Drives to Date

Super Talent Technology, a leading supplier of dynamic random access memory (DRAM) and flash memory products, has announced its new UltraDrive series of solid-state drives (SSDs) in 2.5” form-factor that will offer unprecedented levels of performance.

Super Talent’s new UltraDrive LE solid-state drives based on single-level cell (SLC) flash and available in 32GB, 64GB and 128GB capacities boast with sequential read speed of 230MB/s and sequential write speed of 170MB/s. The multi-level cell (MLC) flash-based Super Talent UltraDrive ME offers 32GB, 64GB, 128GB and 256GB capacities as well as 200MB/s read speed and 160MB/s write speed, similar specs are offered by OCZ’s recently launched Vertex SSDs as well as some advanced SSDs by Samsung Electronics.

“The UltraDrive LE represents a quantum leap forward in storage performance that is simply staggering. It excels in every metric that’s relevant to data centers: sequential and random read and write speeds, transaction rates and access and seek times. It also has a considerable advantage over 10 000rpm hard drives in power consumption and MTBF. This product sets a new standard in enterprise storage” said Mr. C.H. Lee, Super Talent chief operating officer.

The new solid state drives from Super Talent clearly outperform everything that was offered by the company previously. It remains to be seen, however, whether the pricing of the products will remain on the levels where consumers can afford them amid economic downturn.

UltraDrive LE and ME SSDs will available in January 2009. Prices are unknown.

Intel Releases Pre-Production Windows 7 Graphics Driver for Developers, OEMs

Intel Corp. on Wednesday said that it was making pre-production Windows 7 driver for its graphics cores available to original equipment manufacturers as well as software developers. The company appears to be among the first among suppliers of graphics adapters that releases drivers for the next-generation Microsoft Windows 7 operating system.

“Intel is making available for testing its preproduction WDDM1.1 graphics driver, enabling the full Windows 7 experience. The driver is the result of an ongoing collaboration with Microsoft to provide OEMs and developers with drivers that deliver all of the required WDDM1.1 features for Windows 7. As a result of the collaboration, OEMs and beta users can stay in step with Windows 7 prereleases for smooth product development,” a statement at Intel’s web-site reads.

Microsoft Windows 7 operating system is projected to feature very similar driver model as Windows Vista, therefore, it is unlikely to be hard to create Windows 7-compatible drivers. Nevertheless, it is noteworthy that Intel is already making the driver available well ahead of the OS’ launch.

Microsoft have advised both OEMs and developers to start testing of hardware and software with Windows 7 as soon as the system is made available for partners of the world’s largest software company. Microsoft released pre-beta Windows 7 in late October.

Although the WDDM 1.1 driver from Intel hardly supports forthcoming code-named Larrabee discrete graphics processors and probably only supports modern built-in graphics cores, its release emphasizes the importance of high-quality graphics drivers for the Santa Clara, California-based chipmaker.

Nvidia’s New Dual-Chip Graphics Card to Launch in a Month, First Image Emerges

Nvidia Corp. is expected to show off or even formally launch its new graphics card featuring two graphics processing units (GPUs) in about a month time at the Consumer Electronics Show in Las Vegas, Nevada. Meanwhile, the first image of the novelty has just emerged on the Internet.

The new graphics accelerator powered by two Nvidia GeForce GTX 200-series graphics chips will consist of two print-circuit boards each carrying GeForce GTX processors as well as 896MB of GDDR3 memory connected to GPUs using 448-bit memory bus, according to the image published by VR-Zone web-site. It is interesting to note that according to Expreview web-site, the new dual-GPU board by Nvidia will have 480 stream processing units, thus, the product will not carry two GeForce GTX 260 core 216 chips made using 55nm process technology, as previously expected.

















Nvidia is known for quite unexpected behaviour, therefore, it is completely logical that the new dual-GPU “GX2” board will feature higher performance than anticipated and will indeed have 480 stream processing units enabled in total and operating in multi-GPU SLI mode. As previously noted, while performance of two GeForce GTX 260-216 graphics boards may be higher compared to the ATI Radeon HD 4870 X2, it may not be enough to become successful on the market.

It is projected that the novelty will be launched on the first day of CES, the 8th of January, 2009. It is not completely clear whether Nvidia plans to start sales of the novelty on that day, or will just demonstrate the product and formally name it.

Nvidia did not comment on the news-story.
