A computer made entirely of sodium acetate, known as hot ice, solves mazes and other problems. It also occasionally hangs. If you've ever used a chemical hand warmer, you'll be familiar with sodium acetate. These bags of liquid are supersaturated solutions of sodium acetate that has supercooled to ambient temperature. Clicking a metal disc in the solution creates a nucleation center that causes the solution to rapidly crystallize, releasing heat. Heating the solid turns it back into a liquid, thereby recharging the hand warmer.
Toshiba will sell its first Blu-ray DVD player starting in November, the company announced Thursday.
The BDX2000 will retail for $249.99. It includes BD-Live, which lets users take advantage of Web-based interactive features via an Ethernet connection. The device also includes an SD card slot, which may be required to access some of the BD-Live content, Toshiba said.
The concept of space-based solar power was introduced way back in 1968, but it’s only recently that the world has latched on to the idea. Japan is definitely getting in on the action with its latest spacey plan - a $21 billion solar-powered generator in the heavens to produce one gigawatt of energy, or enough to power 294,000 homes.
On a recent edition of Dragons’ Den, Jason Roberts, founder and CEO of a company called Tech21, managed to convince Peter Jones and Theo Paphitis to part with £150,000 (in return for a 40% stake in his business) for what is effectively a range of laptop bags, MP3 player and mobile phone cases.
Advanced Micro Devices has launched a low-power version of its six-core Opteron processor in time for VMworld, a key virtualization show that opens on Monday.
The six-core AMD Opteron EE consumes 40 watts, and is designed for 2P servers, among the most popular in the virtualized server space. The chip will cost $989, and will begin shipping on Monday.
AMD should be launching one more three core CPU based on Heka 45nm three core, which is nothing more than Deneb with one core disabled.
The currently available Phenom II X3 720 at its 2.8GHz is selling for about €90 in Europe or in the states $119.00 including free shipping and this baby will soon get its 3.0GHz sibling.
The new CPU will be under the Phenom II X3 740 brand and its specs include 3.0GHz speed and 7.5MB of total cache but we don’t know the launch price as of yet.
Researchers show that antiferromagnetism has inertia. As a result, you can flip the magnetic field orientation by giving it a quick push and walking away while it does the rest itself. It may be a while before this tech shows up in your PC, however.
It has been reported that the new Radeon HD 5800 Series will support a performance equal to 2 terrabytes of FLOPS (Floating point Operations Per Second. ) The news comes after it has been revealed that ATI Cypress will now become the Radeon HD 5800. As reported from TrustedReviews, the ATI Radeon HD 5850 and 5870 cards will be launched sometime in September, paving the way for a public release in October.
UPDATE: AMD has contacted X-bit labs claiming that it has not announced any simultaneous multi-threading technologies for Bulldozer processors. Still, there are other multi-threading implementations that may still be supported.
Advanced Micro Devices announced during Hot Chips conference that its next-generation code-named Bulldozer microprocessors will feature a multi-threading technology (SMT) which would be akin to Intel Corp.’s well-known HyperThreading.
Since Intel's Lynnfield can run up to eight cores in Hyperthreading, Intel has figured out how to distinguish Lynnfield Core i7 branded SKUs from Core i5.
The logic is very simple. Core i7 has four cores and eight threads enabled, while Core i5 has four cores and four threads enabled.
They both need discrete graphics as Intel 5 series chipset don’t have any IGP as IGP is now part of Clarkdale CPU. However some desktop Clarkdale IGP CPU with 32nm dual-core and four threads inside will end up with Core i5 brand, just to make things a bit more complicated.
