When Jason played with the Palm Pixi, Palm implied it wasn't quite as gutsy as the Pre—it's gonna be cheaper, after all—but didn't get into details. Well, Palm InfoCenter's got the full breakdown for its Qualcomm MSM7627 brains:
Two ARM cores, one running at 600MHz (for apps) and another at 400MHz, with a 200MHz 3D graphics core that supports OpenGL 2.0 (like the iPhone 3GS, which is actually an advtange over the Pre).
It's hard to know how much different it's gonna feel like in practice versus the Pre until we got our hands on a final unit—there's plenty of time for optimizations and other plumbing work this far out. [Palm InfoCenter]
