The bar for silent graphics cards is set to rise again. A number of sites are reporting that PowerColor plans to release passively cooled ATI X1950 Pro and XT cards, with a $10 price premium over the reference design. If these cards make it to market in Q1 2007, as predicted, they should be the most powerful passive options available.
HKEPC claims to have the scoop on Intel's latest Ultra Low Voltage CPUs. These parts, designed for web appliances and sub-notebooks, are designed to consume 5W, less than the chipsets needed to feed them. Unfortunately, the quickest clocks in at 1.2 GHz.
Finally, Anandtech has spent some time with the new, 65nm Brisbane cores from AMD and reports that, while some compromises had to be made, the new 5000+ uses some 10 to 20 watts less than the old version. While this is promising news, for now the EE HTPC 3800+ is even thriftier, and Intel's Core 2 Duo offers more performance-per-watt.
