Microsoft's (NASDAQ: MSFT) Xbox One launched on November 22, 2013 in 13 geographic locations. The company initially reported 1.2 million units shipped in 3Q13 with 5 million units in 1Q14, for a total of 6.2 million Xbox One units shipped to-date; these metrics are sales to retail channels and do not tell us how many have been put into consumers' hands. Microsoft previously noted in the end of January that 3 million units had been delivered to customers.
After offering reddit's computer hardware & buildapc sub-reddits the opportunity to ask us about our nVidia GTC keynote coverage, an astute reader ("asome132") noticed that the new Pascal roadmap had a key change: Maxwell's "unified virtual memory" line-item had been replaced with a very simple, vague "DirectX 12" item. We investigated the change while at GTC, speaking to a couple of CUDA programmers and Maxwell architecture experts; I sent GN's own CUDA programmer and 30+ year programming veteran, Jim Vincent, to ask nVidia engineers about the change in the slide deck. Below includes the official stance along with our between-the-lines interpretation and analysis.
In this article, we'll look at the disappearance of "Unified Virtual Memory" from nVidia's roadmap, discuss an ARM/nVidia future that challenges existing platforms, and look at NVLink's intentions and compatible platforms.

The name is still unknown, but what will eventually become DirectX 12 should be shown off at GDC shortly; we'll be in attendance to report on the new announcements and will also be attending the GPU Technology Conference the following week, so check back for deeper analysis as we are exposed to information. In the meantime, Microsoft's new iteration of DirectX has some between-the-lines reading for AMD's Mantle.
