Celery 1.2@1.6GHz $108 on price watch
celery .13u @ 1GHz/133fsb = better performence than .18u PIII 1GHz /133fsb
so
celery .13u @ 1.6GHz about = to performence or better in some cases than 1.6GHz athy but price is about the same
Hmmm where did that big price/performence ratio go. Today it is pretty much gone. Tommorow may be different though
If you wonder how they got the .13u celery to 7.5 multi and 133 fsb, it was done with a engineering sample

Its IPC was about right in the middle between a tualtin PIII and a cumine PIII. We all know the cumine PIII pretty much kept up with the old tbird but was slightly beaten in some cases. If you followed the thread above I showed in the synthetic benchies in sandra that my 1.6 celery beat the XP in the FPU bench in multimedia and won in the ALU segment of the cpu bench. The XP was at 1.6GHz as also the celery .13u. As for the enourmous amount of memory through put the Athy or PIV have compared to the i815. For some reason it doesn't seem to do the 1.6 PIV anygood. A 1.6 Celery would kill it in pretty much any bench you through at it and the ATHY with like 2 time the through put of the i815 you would think its performence would rape the celery too but it doesn't either.
I will admit the XP is a very nice chip but as for price/performence in comparison to the celery @1.6Ghz, today it just isn't there like it used to be.
