The transistor is one of the most profound innovations in all of human existence. First discovered in 1947, it has scaled like no advance in human history; we can pack billions of transistors into complicated processors smaller than your thumbnail. After decades of innovation, however, the transistor has faltered. Clock speeds stalled in 2005 and the 20nm process node is set to be more expensive than the 28nm node was for the first time ever. Now, researchers at NASA believe they may have discovered a way to kickstart transistors again -- by using technology from the earliest days of computing:  The vacuum tube. No, really.  Stop laughing. Once upon a time, vacuum tubes were the fundamental... Read more...
Ever since AMD announced it would build an ARM processor, there've been questions about how the company would balance its x86 and ARM obligations and product lines. Today, the company gave a major update to how it sees the future of these products. This year, AMD will debut its first Cortex-A57 based server (codenamed Seattle). In 2015, AMD will launch a 20nm SoC family around the new Puma+ core and a second-gen Cortex-A57 chip -- and those two CPUs will be drop-in compatible with each other (codenamed Project Skybridge). In 2016, AMD will follow up with its own custom ARM architecture implementation. One of the major changes coming next year is that both the ARM and x86 chips will apparently... Read more...
After a quick search of Newegg’s site, we’ve found that Intel’s trio of initial Core i7 processors and an array of X58 Express chipset-based motherboards have been made available, just shy of two weeks since our launch article hit the web. The Core i7 920 (2.66GHz), 940 (2.93GHz) and Core i7 Extreme 965 (3.2GHz) are all selling for a small premium at the moment--$319, $599, and 1069, respectively—but the X58 motherboards are priced right in line with expectations. MSI’s offering is the least expensive at the moment at about $220, and ASUS’ flagship Rampage II Extreme is currently the most expensive at almost $400. Coincidentally, we’ve got MSI’s X58 Platinum and ASUS’ Rampage II Extreme in the... Read more...
CNET blogger, Brooke Crothers, reports that AMD is running into compatibility issues with its quad-core Phenom CPU. Some motherboard makers and system builders are mistakingly trying to pair the 125-watt, quad-core Phenon with motherboards that only support the lower-power, 95-watt AMD processors. Crothers includes these quotes from AMD spokesman, Jake Whitman: "They've taken an enthusiast-class quad-core part and paired it with a mainstream motherboard..." "And not all motherboard manufacturers have tweaked their boards to support a 125-watt TDP..." "We've never made claims that 780G motherboards are enthusiast-class motherboards." Enthusiasts and hobbyists have dealt with just these sort... Read more...
Despite many programs still struggling to take full advantage of 2 or more cores, AMD appears to be planning on jumping past 8 cores and going straight for 12!  AMD has dropped more than a few clues that something like this was coming:"The first breadcrumb comes with a new "native six-core" Shanghai derivative, currently codenamed Istanbul.  This processor is clearly targeted at Intel's recently announced six-core, 45nm Dunnington processor."The second clue was when AMD execs and engineers began to stop referring derisively to Intel’s practice of putting two chips on a single die, and began to examine using that approach themselves.There are no early performance estimates worth reporting at this...

The ultimate demise of the single-core desktop chip from AMD will have to be postponed for a little while longer.  AMD is still phasing out chips such as the Sempron LE-1150, but they're actually planning a higher-frequency replacement part called the LE-1660.  Intel is currently in the process of phasing out all single-core CPUs from their desktop lineup, which could provide AMD with a little breathing room at the ultra-low end of the spectrum.Sadly the LE-1150 isn't the only CPU we'll be saying goodbye to soon:“In addition to the Athlon 64 X2 6400+, 6000+ and 5600+, the company has also informed customers that final orders for its Athlon 64 X2 4200+ will be taken at the end of this...

As with all rumors, please take the following with a grain of salt.  A new rumor is being circulated that AMD's upcoming triple-core CPUs are likely to hit the shelves sometime in March 2008:“AMD will launch two B2 stepping triple-core CPUs, Phenom 8600 and 8400 in March of next year, while in the second quarter, the company will launch three more models, Phenom 8700, 8650 and 8450.The Phenom 8400 and 8600 will feature core frequencies of 2.1GHz and 2.3GHz, respectively, while the Phenom 8700 will clock at 2.4GHz. Phenom 8650 and 8450 will be based on B3 stepping cores, and will have frequencies of 2.3GHz and 2.1GHz, respectively. All five CPUs will have a 95W TDP.The high price/performance... Read more...
We now have a launch date, or at least launch month, for AMD's triple-core CPUs, which they announced in September.AMD recently notified its partners that it plans to launch two triple-core CPUs (Toliman) in February next year while two dual-core CPUs (Kuma) will appear by the end of the second quarter, according to sources at motherboard makers.The triple-core 7700 and 7600 will have core frequencies of 2.5GHz and 2.3GHz, respectively, and a TDP of 89W. frequencies for the dual-core 6250 and 6050 have not yet been set, but the CPUs will have a TDP of 65W, the sources revealed.Pricing: still unknown, and it's pricing that will tell if these can compete with Intel's offerings....

Despite the day, we are not trying to scare you or anything, but if you are one of the many who are switching from desktops to notebooks in your life (as evidenced by sales figures), Intel seems to be having trouble keeping up with demand.Due to Intel's misjudgment of notebook demand, the gap between the company's production capacity and market demand is increasing. Intel recently stated to makers that it will readjust its production capacity to solve the shortages and it expects the problem should be solved by the end of the year.By the end of the year, eh?  Seems based on that date though, that there might be shortages for people looking for a notebook-sized holiday gift this year. ...

Another one from the rumor mill over at the Inq, but it seems possible that AMD might actually release a three core CPU. At first glance such a story might seem like the wild tales of journalists who are off their meds, but there may actually be a few advantages of losing a core. Consider that Barcelona just debuted at 2.0GHz with four cores and AMD claims that the chip will scale up to higher clock speeds before the end of the year. Just how far is unclear, but the number 2.5GHz has been tossed around quite frequently. Now imagine if they were only working with three cores instead of four. What clock speed could a tri-core Barcelona hit? What programs might benefit from this? Here's... Read more...
Between AMD's surprise SSE5 announcement and the official launches of Barcelona and Penryn, it's becoming difficult to tell who is doing the launch crashing these days.  Right before Barcelona is due to launch, it looks like Intel is going to release a few power efficient CPUs riding the 1333MHz FSB. "Intel has announced three new Core 2 Duo processors—the E6550 at 2.33GHz, the E6750 at 2.66GHz, and the 3GHz E6850. The new cores are being launched synonymously with Intel's Q35 chipset, the ICH9-D0 southbridge, and the new Intel network controller, the 82566DM. All three are running on Intel's new 1333MHz FSB and sport a 4MB L2 shared cache." We're just waiting for Via to spoil all upcoming... Read more...
AMD Announces Broad Software Ecosystem Support for Industry’s First x86 Native Quad-Core Solution —Windows, Linux, Solaris and VMware environments are optimizing to take advantage of AMD’s native quad-core “Barcelona” processors — SUNNYVALE, Calif. - Aug. 9, 2007 - AMD (NYSE: AMD) today announced that leading x86 operating system (OS) and virtual infrastructure (VI) vendors are embracing support for AMD’s native Quad-Core AMD Opteron™ processor, code-named “Barcelona.” Microsoft, Novell, Red Hat, Sun Microsystems and VMware are optimizing...

While it's a short news post, it does contain an interesting tidbit of information.  It seems that AMD is planning to follow the strategy of rival Intel by sticking two of their upcoming quad-core CPUs on one die and calling it an 8-core CPU. Intel is using the same strategy at the moment with their quad-core designs, which are really two dual-core CPUs on the same die. So the question is, can AMD double up their native-quad core CPUs before Intel can either figure out a way to put 4 dual-core CPUs on a single die, or develop a native quad-core? "HOW DO YOU get from Montreal to Shanghai? If you are AMD, you put two Shanghais on an MCM and get to eight cores. How? HT3."... Read more...
AMD's roadmap for CPU production has shown steady progression in the company's goal of shrinking die sizes from 90nm to the eventual goal of 35nm in the next few years, but will that move be made soon enough to keep AMD's offerings comparable to Intel's? A great deal of debate has been centered around whether AMD or Intel will move into the production of smaller, more efficient die sizes first, but AMD may be closer to shrinking it's CPU dies then it seems. Recently AMD's Senior VP, Marty Seyer, alluded to the successor of the 65nm Barcelona core, the Shanghai. The Shanghai core is intended to be AMD's first 45nm processor and is... Read more...
