The D8M is the 8400GS, a 65 nanometre part and NB8M is Nvidia Geforce 8400M 256MB with a maximum of 512MB shared memory.
In this case NB stands for notebook while M describes the entry level chip and D8M is also the 8400 GS, 80 nanometre part.
We wonder how will we know when Nvidia replaces this graphics chip with a much smaller and cooler 65 nanometre part and that is only in case if this notebook doesn’t come with a 65 nanometre G98 based chip at the first place.
