  It would be interesting to know if this peak performance is obtained
  with IEEE compliant FP or shortcuts acceptable for 3D graphics.

  This figure is interesting if only to suggest a clock rate target
  of about 750 to 800 MHz.

  Both of these figures are peak performance values which essentially
  means you cannot achieve higher performance.  For real applications
  you typically achieve a lot less.  If the Toshiba chip sustains 20%
  and the Merced sustains 50% of these peak values on real customer
  applications it will be impressive.

All opinions strictly my own.
