ATI’s latest in their Radeon HD line has finally been confirmed as the HD 4890 X2.
While initially AMD maintained the notion that there wasn’t a market for anything beyond the HD 4870 X2 because of the card being absolutely top of the line, they’ve still gone ahead with the 4890 X2.
Reportedly, the new graphics card will have two GPUs running at least 1GHz per core, and depending on the SKU a customer buys, they can expect 2GB or 4GB of memory. Unfortunately, that’s the most specific information currently available.
No word yet on pricing or availability on the new powerhouse, but it is expected that Nvidia will follow this up with a new ultra high-end offering of their own.
Looking for a dual-band router so you can run two independent Wi-Fi networks, using one frequency band for data and the second for streaming media? Scratch the DGL-4500 off your list, because D-Link’s definition of “dual-band” means operating on either the 2.4GHz band or the 5.0GHz band—not both at the same time.
When we think of a dual-band router, we envision something like the Linksys WRT600N we’ve been using as a reference point. That device has separate 802.11n Draft 2.0 radios that enable us to run two independent wireless networks. That’s not to say the DGL-4500 is a lousy router; in fact, it delivered far superior performance at long distances than the WRT600N. Where the Linksys box is nearly useless when our Wi-Fi client is outside our test home—delivering throughput of just 0.7Mb/s at one exterior location and 1.2Mb/s at the other—the D-Link delivered exceptional throughput of 18.0Mb/s and 6.44Mb/s, respectively.
Ever wonder what happens when you take a Jensen #75 and connect it to a lego Technic motor using a rubber band? Neither have we, but thanks to YouTuber twdunbar, we now know, and it's pretty damn cool. Using the parts just mentioned, twdunbar fashioned together a Steampunk-inspired USB charger for his iPod, but it can also be used for other devices.
"The motor is being driven and so it acts like a generator, which feeds into a voltage regulator circuit to give a continuous 5V to the iPod (or any USB device)," twdunbar wrote on his YouTube video page.

To an internet based company, server infrastructure is the secret sauce that can really help a company pull ahead of its competitors. It determines the quality of service its customers will receive, and their cost and efficiency will have a huge impact on the bottom line of the company. To Google this secret was a carefully guarded one, with few outside of the company having any real details. The only thing that we knew for sure is that they were built in house using parts that are generally available to every PC builder. This all changed last week when Google decided to lift the veil of secrecy to a group of IT professionals.
Each server measures about 3.5 inches thick, and is designed in a custom rack for easy stacking. Each unit sports two x86 processors either from Intel or AMD, contains two hard drives (presumably configured as a raid 1), and eight memory slots. These components are mounted on a Gigabyte motherboard, and protected by built in 12-volt battery that also serves as a UPS.
The built in battery was perhaps the biggest secret that was revealed and is a slap in the face to traditional thinking when it comes to large scale battery backup. Typically, server farms employ massive uninterruptable power supplies in the event of a power failure. The biggest problem with this approach according to Chris Malone from Google is the ability to scale it perfectly for the number of servers, and inefficiencies inherent with the technology. “Large UPSs can reach 92 to 95 percent efficiency, meaning that a large amount of power is squandered. The server-mounted batteries do better, Jai said: "We were able to measure our actual usage to greater than 99.9 percent efficiency."
Google’s approach to server infrastructure is defiantly unique, and it’s use of low cost customer grade hardware defiantly helped them survive the early years on razor sharp margins.

For some time now Intel has been working on a Linux-based operating system (now in its alpha stage of testing), named Moblin. The goal of Moblin is to provide the Atom CPU a light and fast OS that is far less demanding than a full version of Windows.
According to those in the alpha test, Moblin can offer two second boot times (with some optimization). If all this were true, then it would give us the fastest booting OS available. Intel’s Open Source Technology Center director Imhad Sousou is very much on board as well, stating, “We think that two second boot is possible.”
A two second boot would provide an ideal platform for mobile systems (such as netbooks and MIDs) to operate on. For many, having a system in sleep mode (which drains the battery) is preferable to booting the system each and every time they want to use it. The concept of a two second boot would eliminate the need for this.
So, given the concept of a two second boot, would you be willing to ditch Windows and give Moblin a try? Let us know in the comments!
If you spot a good deal on an LCD monitor, you may consider pouncing. Putting off that purchase could be rolling the dice at higher prices, according to data by iSuppli. The market research company notes that an increase in demand from China, driven by the impact of China's rural consumer stimulus program, has led to rising prices for LCD monitor panels. Also to blame are an increase of orders from brands and retailers, iSuppli says.
"These brand and retail orders mostly stem from demand for inventory replenishment because channels have kept their stockpiles at lower-than-normal levels since the end of 2008," iSupply noted. "With many panel prices for monitors having been drastically slashed to less than cash-cost levels, panel buyers in February started purchasing in droves in order to build a supply of cheap panels."
Increases thus far haven't been anything to warrant hitting the panic button. According to iSuppli, average pricing for most LCDs and small-sized TV panels increased anywhere from $2 to $3 in March compared to February. And while prices are expected to rise some more in the short-term, iSuppli warns that it's too early to say that a recovery is taking place in the LCD industry, as the influx of orders are not expected to be sustained.
More and more custom cooling solutions are starting to appear for Nvidia's GeForce GTX 285 videocards, with one of the more intriguing options belonging to MSI. The company has taken traditional heatpipe designs, fattened them up, and slapped them on its N285GTX SuperPipe OC graphics card.
"Today, MSI is pleased to announce the N285GTX SuperPipe graphics card, which not only brings to bear the powerful NVIDIA GPU - GeForce GTX 285, but, via the revolutionary ‘SuperPipe’ and Twin Frozr thermal design, offers a high performance and thermal efficiency graphics card," MSI wrote in a press release.
The aptly named SuperPipes consiste of 8mm thick heatpipes, which are up to 60 percent thicker than traditional heatpipes. According to MSI, the wider design leads to 90 percent better cooling performance. The N285GTX has been outfitted with five heatpipes in all, two of which are SuperPipes, on an all-metal heatsink with dual fans.
Engineers working together from Fusion-io and Hewlett Packard were able to achieve about 1 million IOPS (input/output per second) and 8GB/s sustained throughput in a custom-built HP ProLiant DL785 G5 server with four quad-core AMD Opteron processors. To reach the high level of IOPS, the server included five 320GB ioDrive Duos and six 160GB ioDrives.
"The ioDrive and ioDrive Duo are to supply the extreme storage performance (for data centers) at a fraction of the power, cooling, and per unit-of-processing-power price compared to traditional solutions," said David Flynn, chief technology officer of Fusion-io, in a statement.
The ioDrive and ioDrive Duos used consist of single level cell (SLC) flash memory and come rated for 48 years with the company's wear leveling algorithm. Both drives also utilize the PCI-E interface.
According to the company, it was left with no other choice after two years of licensing talks didn’t bear any fruit. “We couldn’t find a common viewpoint with Apple, so we decided we had to take action,” a spokesperson for the company told The NYT.
Elan has accused Apple of violating two off its patents related to touchscreen technology. It maintains that the MacBook and iPhone/iPod Touch violate its patent rights.
