Nvidia doesn't need to acquire ARM to sell systems with unified memory. The Tegra boards are all mixed-address-space systems, and CUDA lets you manipulate memory over PCI. They see the writing on the wall, which is why they've been building systems for the past decade that reflect this philosophy.

If you think it's hard to imagine Nvidia hardware running on a developer desktop, wait until you hear about what happened when Macs tried entering the server market.
