NeXT/Rhapsody/PPC Speed vs. NT/Intel.

via MacWeek from 2/97

>Running the numbers
Here's how Mac OS 7.6 compares to Windows 95 in the tests. A PowerPC
601 is about the same as a PowerPC 603e, which is comparable to a Pentium
at any given megahertz. A Pentium Pro is about 60 percent faster than a
Pentium at the same clock speed. The PowerPC 604 is about 70 percent faster
than a Pentium Pro at any given megahertz. The PowerPC 604e is about 20
percent faster than a 604 at the same clock speed.

When we look at the comparisons across several OSes, but within platform
architectures we see Windows NT 4.0 is about 6 percent faster than
Windows 95 on Pentiums and Pentium Pros. And NeXTstep is about 80
percent faster than NT 4.0 on both Pentiums and Pentium Pros.

NeXTstep up to PowerPC
What happens if we extrapolate for a PowerPC version of NeXTstep (the
forthcoming Rhapsody) based on the benchmarks we know? Mathematica
on NeXTstep PowerPC would outperform Mathematica on Windows NT by
at least 80 percent at equivalent clock speeds.

Finally, let's take these performance ratios and plug them into the
computing scene of late 1997 - one dominated by 233-MHz Pentium
Pro/MMX Windows NT systems competing with 300-MHz 604e-based
Rhapsody Macs. At that point the Macs' performance edge will be nearly 400
percent. This is an advantage that Apple and Mac OS cloners can really
exploit.<
