NASA's Orion space capsule: what GPU?

[vailr]

According to a NASA video during Friday's successful Orion space capsule test launch, they're planning to save quite a bit of weight by using touchscreen "on glass" virtual control switches inside the Orion command module. I'd be interested in learning more about this, such as: what exact GPU specifics are being used (in the prototype equipment, at least), what type of backup equipment & redundancy, cosmic ray & vibration protection, etc.
Anyone know of public web links?
Note: the first manned Orion launch isn't scheduled to happen until 2021, so I guess all that kind of detail is subject to revision.

The Vehicle Management Computer is by Honeywell..
"Honeywell Aerospace designed and developed Orion’s command and data handling hardware, navigation systems and core operating software. These systems work together for Orion’s overall flight management, building on Honeywell’s existing technology developed for commercial aircraft. "

Here's some information about the (now 12 year old) Power-PC CPU being used:

No GPU-specific info, however.
