    On a NV 35 ..yes

    On all the other FX line-up..no.

    And as you are aware the money is not on the high end.

    I´m confused now...I know the R3xx´s use FP24; so what kind of precision is NV35 using after all?

    As of today, we see the point... ;)

    BTW, MuFu pointed out something interesting in DH's Terry M. interview:

    Hmm... if it signs R500 where is R400 in the timetimetable? End of this year?

    My money is on year end for R400, but I am not conviced that R500 is the reason for the revamp next summer.

    Apparently the NV35 has dramatically improved FP16 performance, up to near FX12 performance levels (according to Uttar's benches), so the NV35 should use a mix of FP16 and FP32.

    Of course, the problem is that ARB_fragment_program still doesn't allow instruction-level control over precision, but instead has a global precision hint. It will be very hard for drivers to properly decide which precision to use...that is a job best left to the shader writer.

    "What will nVidia and ATI release in their next refresh cycles?

    We could tell you shocking details, but then we’d have to kill you. ATI’s next product release should be the R400, which will include a substantial number of new features and silicon on the chip."

    Wow... what a prophecy... Dodona... ;)
