Intel plans to unveil a lot of 45 nanometer Penryn based processors and the lowest-priced of them all, Core 2 Duo T8100, will cost US$195.
This CPU will work at 2.1GHz and FSB800, it comes with 3MB of cache memory and needs 0.7 to 1.3V to work. Naturally, it is uFCBGA or socket P compatible, and it will be available in many notebooks that will surface in January. There will be a boxed version as well, but very few people actually upgrade CPUs on a notebook and there is the compatibility factor to consider, as well. You will need a board that will support FSB800, for certain, and you will probably need a bios update, too.
Depending on the processor, Intel can scale between 3MB and 6MB in mobile Penryn 45nm processors, but only the top versions will come with a full 6MB. All these CPUs will be introduced on January 6.
