Dear Wbmw: First generation Centrino parts are all single core. For your information, Banias parts were the first Centrino generation and all of AMD's parts blow those away on performance and idle power. Dothan was second generation Centrino and were all single core. Yonah was first dual core Centrino, but the third generation. Merom is fourth and Penryn will be fifth. Now Pentium Duo is Yonah for Mobile, but P4 Celeron for desktop. Don't be confused over which refers to which. P4 Celeron is 64 bit capable, but Yonah isn't. P4 Celeron is a power hog like all the P4 series "Netburst" CPUs. And idle power depend on which chipset is being used on the MB. 965Gs aren't that good at idle either even when paired with a Yonah. Merom is terrible at idle power. Penryn might be better. We will have to see when its production form is tested with its integrated graphics chipset whose name escapes me at the moment. Turion paired with 690G does well. Griffith with 790G will be better yet. VC-1 and H.264 players suck compute cycles quite a bit except that ATI chipsets include UVD which offloads that to the internal GPU which is much more power efficient at it. AFAIK, the Intel chipset that will be paired with Penryn doesn't have that accelerator. For that they would have to pair it with either a nVidia 8xxx or ATI HD 2xxx discrete GPU. That would throw their idle power out of whack. Sure the GPU is more powerful, but the cost both in dollars and power are higher. And AMD can do it as well with the added advantage of using the internal GPU when on battery and the discrete GPU when plugged in without user intervention between the two modes (other than plugging or unplugging the power cord). You get the best of both worlds. Pete
