No it doesn't. You have to order the model that comes with 512GB of storage default to get the 8 Core GPU. That said, the performance difference you get with the extra core (~10% or less) really isn't worth the cost, I'd say (and did) just save your (my) money.
Thanks, Malus120. I don't really need the 16GB RAM for my uses either but for an extra $180 via the education store, I figured it was a good investment.
How are you liking yours? What are your primary uses?
