ATI has officially announced
its Mobility Radeon X1600, the first member of its new Radeon X1000
series to be available for notebooks. Like its desktop counterpart, the
Mobility Radeon X1600 has an unconventional architecture with 12 pixel
pipes, five vertex units, four texture units, four ROPs, and a 128-bit
memory bus. With 470MHz core and memory clocks, it runs significantly
slower than the Radeon X1600 XT, although clock speeds are closer to
the 500MHz core and 390MHz memory clocks proposed for the Radeon X1600
Pro.
