well form what i got from pcworld the batt life will be the same as current pentium m's
Yonah is a bit more integrated than some of the other dual-core designs, for desktops and servers, which were revealed on Tuesday, Eden said in a presentation after Maloney's keynote. Because notebook users won't stand for a step backward in battery life, the two Pentium M cores within Yonah had to be very closely synchronized for power consumption and performance, he said.
Even with those enhancements, Intel was unable to improve the battery life of notebooks based on Yonah compared with notebooks using the Sonoma platform of the Dothan processor and Alviso chip set, Eden said. Separate processing engines require a significant increase in power, and Intel is extremely proud of the fact that it was able to hold the line on power consumption as compared to single-core versions of the Pentium M, he said.
Concerns about the slow pace of improvement in battery life should be assuaged by the performance of the new chip. "This should be one hell of a gaming machine," Eden said. He declined to directly compare Yonah's performance to that of Intel's Pentium 4 desktop processor or Advanced Micro Devices' Mobile Athlon 64 chip, but said he was confident that Intel had developed a competitive product.
Using two cores allows the processor to quickly run multithreaded applications or run two single-threaded applications simultaneously, Eden said. This performance will be enhanced with Intel Virtualization Technology (VT) and Intel Active Management Technology (AMT), two enhancements that allow IT managers to upload software updates or bug fixes to notebooks that are offline.
VT and AMT will be available with Yonah as part of the Napa platform in early 2006, Eden said. Napa also includes the Calistoga chip set, which improves integrated graphics performance, and the Golan wireless chip, which reduces power drain experienced by users connected to wireless networks, he said.
