>Ofcourse they will. They'll just keep on using their "All PPC-processors are >twice as fast as the top-of-the-line Intel/AMD processors, no matter what"
That’s a very centric view. Independent test results was not disclosed.
Refer http://www.geocities.com/sw_perf/ for an example programs to test with.
Refer to http://rss.com.com/2100-1001-961862.html?type=pt?=rss&tag=feed&subj=news
=== Quote =====================================================================
The PowerPC 970 chip, due next year, will run at 1.8GHz, nearly twice as fast as Big Blue's quickest existing PowerPC chip, the 1GHz 750FX.
===============================================================================
The comparison was with IBM's own PPC chips. Where did you get your results?
A 2X speed 1GHz 750FX(current) is not a quantum leap in computing speed (i.e. imagine o/c 2Ghz 750FX chip).
PPC 970(future) was only stated to be twice as fast when compared to the existing IBM's PPC flagchip.
In the case of top-of-the-line Intel processors. Did you forgotten Itanium II(Current)(and soon to be released Itanium III(future)?
In the case of top-of-the-line AMD processors. Did you forgotten AMD K8 (and soon to be released @ H2 2003)? Not factoring soon to released AMD Athlon XP (with Barton core)rumored have better IPC compared to existing T-Bred-B cores.
If you refer to http://www.geocities.com/sw_perf/
PPC solution was behind(compared to X86 solution) with the following benckmarks
1. Maya
2. Lightwave 7.5 (it takes a dual G4@1Ghz to beat a middle end Athlon 1.6Ghz)
3. Cinema4D (about equal @ a given Mhz i.e. non-XP enbled K7@1Ghz(100)G4@Ghz(98))
4. Mathematica
5. OGR
6. SETI
(Note that G4 did well in RC5, and the G4 was competitive with X86s in Photonshop 7 test)
Other benckmarking programs are;
1. Quake III

2. OpenSSL

Most real life benchmarks hasn’t been tested with the latest AMD Athlon XP~2.2Ghz(Tbread-B core) or Intel Pentium 4 ~2.8 Ghz (Northwood core).
(Never automatically equate AthlonPentium 4 in terms of application performance, both has different characteristics.)
Factors for evaluating a HW solution is
1. Main application being used
2. Price/Performance
3. Availability
4. Running legacy software.
>and that's it. No Apple-sheep will dare refute it.
Its Apple's call.
