Actually, the true original design from Intel Israel's team was the Pentium M (which itself was heavily based on both the Pentium III and the Pentium 4 branch prediction and FSB). The Core architecture wasn't a truly "ground up" design, it relied on the Pentium M design. It even inherited the Pentium M's weak FPU (which was redesigned for the Core 2).
Tech That Will Save Our Species - Solar Thermal Power 648
NoMoreCoal writes "Salon has up a story by Joe Romm, former undersecretary of energy during the Clinton administration, discussing a lesser-known alternative energy solution. It's a technology that (he claims) is ready to provide zero-carbon electric power big, fast, cheap and (most importantly) right now: solar thermal power. 'Improvements in manufacturing and design, along with the possibility of higher temperature operation, could easily bring the price down to 6 to 8 cents per kilowatt hour. CSP makes use of the most abundant and free fuel there is, sunlight, and key countries have a vast resource. Solar thermal plants covering the equivalent of a 92-by-92-mile square grid in the Southwest could generate electricity for the entire United States. Mexico has an equally enormous solar resource. China, India, southern Europe, North Africa, the Middle East and Australia also have huge resources.'" Interesting stuff, even if he does mention the Archimedes Death Ray.
Weak Rivets May Have Sped Sinking of Titanic 296
Pickens writes "Metallurgists studying the hulk of the Titanic argue that the liner went down fast after hitting an iceberg because the ship's builder used substandard rivets that popped their heads and let tons of icy seawater rush in. They say that better rivets would have probably kept the Titanic afloat long enough for rescuers to have arrived, saving hundreds of lives. The team collected clues from 48 Titanic rivets and found many riddled with high concentrations of slag, a glassy residue of smelting that can make iron brittle. To test whether this extra slag weakened the rivets, scientists commissioned a blacksmith to make rivets to the same specifications as those used to join steel plates in the hull of the Titanic. When the plates were bent in the laboratory, the rivet heads popped off at loads of about 4,000 kg. With the right slag content they should have held up to about 9,000 kg. Even a few failures because of flawed metal would have been sufficient to unzip entire seams, because as faulty rivets popped, more stress would have been placed on the good ones, causing them to break in turn. The shipbuilder, which is still in existence, denies it all."
Nvidia Physics Engine Almost Complete 179
Nvidia has stated that their translation of Ageia's physics engine to CUDA is almost complete. To showcase the capabilities of the new tech Nvidia ran a particle demonstration similar to Intel's Nehalem demo, at ten times the speed. "While Intel's Nehalem demo had 50,000-60,000 particles and ran at 15-20 fps (without a GPU), the particle demo on a GeForce 9800 card resulted in 300 fps. In the very likely event that Nvidia's next-gen parts (G100: GT100/200) will double their shader units, this number could top 600 fps, meaning that Nehalem at 2.53 GHz is lagging 20-40x behind 2006/2007/2008 high-end GPU hardware. However, you can't ignore the fact that Nehalem in fact can run physics."
Ray Tracing To Debut in DirectX 11 219
crazyeyes writes "This is breaking news. Microsoft has not only decided to support ray tracing in DirectX 11, but they will also be basing it on Intel's x86 ray-tracing technology and get this ... it will be out by the end of the year!
In this article, we will examine what ray tracing is all about and why it would be superior to the current raster-based technology. As for performance, well, let Intel dazzle you with some numbers. Here's a quote from the article: 'You need not worry about your old raster-based DirectX 10 or older games or graphics cards. DirectX 11 will continue to support rasterization. It just includes support for ray-tracing as well. There will be two DirectX 11 modes, based on support by the application and the hardware.'"
The Death of the Silicon Computer Chip 150
Stony Stevenson sends a report from the Institute of Physics' Condensed Matter and Material Physics conference, where researchers predicted that the reign of the silicon chip is nearly over. Nanotubes and superconductors are leading candidates for a replacement; they don't mention graphene. "...the conventional silicon chip has no longer than four years left to run... [R]esearchers speculate that the silicon chip will be unable to sustain the same pace of increase in computing power and speed as it has in previous years. Just as Gordon Moore predicted in 2005, physical limitations of the miniaturized electronic devices of today will eventually lead to silicon chips that are saturated with transistors and incapable of holding any more digital information. The challenge now lies in finding alternative components that may pave the way to faster, more powerful computers of the future"
iPhone's Development Limitations Could Hurt It In the Long Run 452
ZDOne writes "Apple might have finally come around to allowing third party developers to create applications for the iPhone, but only up to a point. ZDNet UK claims Apple is leaving itself vulnerable to the competition and to a loss of lustre
by blocking background tasks on the device. The author notes, 'Perhaps it doesn't trust application designers or users very much. Perhaps it wants the best software for itself, where it can limit what it can do in order not to upset its telco friends. Whatever the reason, it reflects badly on Apple. The iPhone is not an iPod; it's a smartphone connecting to a universe of fast-changing data on behalf of innovation-hungry users. The sooner it stops pretending to be a 1981 IBM PC, the better it will be for everyone.'"
NIN's Music Experiment Sells Big Numbers 452
An anonymous reader writes "It looks like Trent Reznor's new Nine Inch Nails album experiment is a success. Among the various options he gave fans, the most expensive was the $300 Limited Edition Ultra Deluxe Package. It took just over a day for that package to completely sell out, earning Reznor $750,000 in revenue from just that option alone."
