They only differ in CPU and UPA bus speeds.  The U1/200 runs the UPA bus
at 100MHz and the CPU at 200, the U1/170 runs UPA at 83 and CPU at 167.
For CPU-bound tasks the 200 will be roughly 15% faster, this is consistent
with SPEC tests.

The Creator3D framebuffer will allow the use of higher resolutions.  Both
should be roughly the same speed.
