Microsoft patent outlines smart power-saving system that reads your diary, leaves a tip
Always leave your PC on while you watch the latest Game of Thrones? Someone at Microsoft evidently does. A granted patent outlines a model that uses historical usage data to predict when it might be able to tweak power needs of the processor in the future, and for how long. So, perhaps you leave your machine on overnight, and jump on at 8am every day? It'd know this and make frugal use of resources accordingly. This, of course, could help fill your pockets and maybe cover that upgrade.
Linux kernel hits version 3.2, plenty of power-saving features in tow
It's a little later than originally anticipated, but Linux kernel 3.2 is finally here. As per usual, it packs a number of improvements -- most them under the hood. Perhaps most exciting are some power-saving features related to graphics drivers, which should help get those battery life issues under control in Ubuntu 12.04. Other improvements include better (and hopefully more stable) WiFi drivers and faster read access to EXT4 formatted file systems. The list of changes is pretty epic to say the least. You can find plenty more detail at the source as well as a link to download the kernel for yourself, though, we highly recommend you wait until it comes to your distro of choice on its own.
Integrated circuits with no standby power could be in use by year's end
There's certainly no shortage of companies working to make electronics of all sorts more energy efficient, but NEC and Rohm Co now say that they're on the verge of a breakthrough that could change things in a big way, and we could possibly see it in "practical use" by the end of this year. As Tech-On! reports, both companies are hard at work on integrated circuits that consume no power at all when they're in standby mode, and turn themselves on only when power is needed. That's apparently possible by making the entire chip nonvolatile, as opposed to many current chips that only use nonvolatile merged memory. According to NEC, that'll let them "cut dissipation for digital consumer electronics in the standby mode to just a few percent of what it is now," and at no expense of convenience. While NEC isn't making any promises for the near future just yet, Rohm says that it'll begin shipping its first custom ICs in the second half of this year, and that the first products using them could start showing up by the end of 2009.
New 80GB PS3 provides minimal power savings, might have 65nm RSX GPU
Last we heard, it was still up in the air somewhat as to whether upcoming PlayStation 3 consoles would house the elusive 65-nanometer RSX graphics processor. According to a curious buyer of Sony's newest 80GB unit, there is a smidgen of data that hints at a 65nm chip actually being under the hood. By using the oh-so-scientific Kill-A-Watt, he discovered that his older 40GB PS3 sucked down 125.8-watts when idle, while the fresh 80GB edition ate up just 111.9-watts. The findings were similar when looking at power draw during DVD playback and while spinning Metal Gear Solid 4. Unfortunately, this mighty fine fellow is planning to return the new unit after being disappointed by the minimal energy savings, so he's not apt to rip the thing open and prove once and for all what kind of GPU is in there. Meanwhile, we heartily suggest that someone do just that and put this question to bed.[Thanks, Khattab]
