    GPU could be clocked slightly higher like say 550MHz instead of 520MHz as in T30?
     
  2. ARM says the Cortex A9 can go up to 2GHz on TSMC's 40G.
    I guess those 1.9GHz can only occurr on single-core operation, though.

    I think it should have more than 10% of higher GPU clocks, given that is has a performance advantage of over 10%. 580-600MHz should be more likely.

    This one is still using LPDDR2 afaik so it shouldn't have any bandwidth advantages either.
    Single-channel 32-bit 1066MHz LPDDR2.
    4.26GB/s to feed four 1.5GHz cores and a GPU that needs to drive a 1080p screen. That's courageous.

    Egypt offscreen:

    Asus Transformer Pad TF700T = 76.60 fps
    Acer Iconia Tab A510 or Asus Eee Pad Memo Me 370T = 72.00 fps

    I don't see a performance difference of over 10%, rather 6%. Unless you should mean the warmup fill test where it suggests a >20% higher fillrate. If it's really clocked as high as you suggest, then it obviously won't show without any reasonable bandwidth increases.
     

  5. Oh okay.
    The TF200 does significantly lower than the A510, 69.5FPS.
    Perhaps it's using different drivers or maybe faster DDR3L like the TF300.

    Could be older drivers or simply the TF200 not clocking its GPU at the T30 peak frequency, no idea. Either way if the GPU in T33 should be clocked at close to or even above 600MHz it would be interesting to see how it behaves with more bandwidth than in the TF700.
