I don't think you are very well informed , dear Pauleron.
The PPC-760 at 300 MHz (yes it is available in higher speeds, but I dont have the data for higher PII and PPC right now) has some impressive specs :
- 1,9 volt core, 3,3 volt I/O, only a mere 6 watt's of power consump.
- Made by IBM, using it's brand new CMOS-6X tech., 0.25æm .
- Uses Inline-cache, wich runs at 100 MHz, (instead of the old 50 MHz,wich used to be normal at all other PPC-), and that combined with 64 K (32 k data 32 k instruction) l1 cache, it is very fast indeed.
But how fast ?
HINT bench marking provides a much better view on how a cpu is going to perform on real-life applications (3d, CAD/CAM, you know, high end stuff , Adobe etc.) than SpecFP/INT. I don't have the data for SpecFP and SpecINT for this cpu, could someone find them ?
The integer performance in MQUIPS of the PPC-300 is 30% better than pII can do. Not that Integer really matters.
The FPU-performance of the PPC-300 shows the real power of it :
Performing TWICE as good as the pII, it proves to be quite a lot faster indeed.
To show that it *really* has some nice thingies inside :
Bipolar Interpolation, one of Intel's speciality's, using mmx, is faster on a PPC 300 (with ordinary C instead of optimized MMX Code)
than on a pII 300 .... (PPC : 0,35 sec, pII 0,36 sec, p200 mmx : 0,826 sec, p200-NO-mmx : 3,30 sec)
And all this is achieved using a pathetic bus speed of 50 MHz.
Apple is going to upgrade to a 66 or 83 busclock (or already did), and it (will) clearly stand in front anything Intel has .
My source is mainly a German Computer Magazine (C'T, nr. 9, pages 86 through 89), and the HINT site : scl.ameslab.gov .
Hope to have you informed well enough.
