Droid X vs. Thunderbolt GPU?

[Alpha Axl]

Does anyone know which is more powerful? I just want to make sure all my emus run as good as they do (if not, better) than on my Droid X. Been using N64oid the past week or so and it's great.

Nothing would make me feel worse than spending $700+ on the phone itself and realize it has a crappier GPU than the Droid X :'(

Thanks!
