As the successor to the current Pentium M (Dothan) and the predecessor to next yearâ€™s Conroe, Merom and Woodcrest cores, Yonah is a very important chip. As a mobile processor Yonah will bring dual core to thin and light notebooks, basically anywhere youâ€™d find a Pentium M, youâ€™ll now be able to find two Pentium Ms. The implications for mobile performance are huge, as multitasking on notebooks has rarely been all that great of an experience. At the same time, Yonah is so much more than just a dual core mobile processor - itâ€™s a predictor of the performance of Intelâ€™s next-generation desktop micro-architecture. Sure, it wonâ€™t have all of the architectural bells and whistles that weâ€™ll see when Conroe debuts at the end of next year, but itâ€™ll have many and that makes it a reference point.
The problem with the Pentium M architecture has been that although itâ€™s traditionally done well at office tasks and obviously in the power consumption department, it has lagged behind the Pentium 4 and Athlon 64 when it comes to FP intensive applications such as video encoding, and to a lesser degree, 3D gaming. With Yonah, Intel has promised to address those performance issues, and even more so with their next-generation micro-architecture later next year. But we tend to want to see things for ourselves, and Yonah will at least give us an indication of how things have improved since Dothan, and whether or not Intel is on the right track to replacing the Pentium 4.
