I was around at the time, performance was very MUCH on Apple's mind because 
nearly every review of any new Powerbook was 'well, still no G5 powerbook and 
cheaper Wintel laptops are much faster, longer battery life, etc. Apple, was 
losing their place rapidly/

Here I have some cool facts for you:

<http://en.wikipedia.org/wiki/PowerPC_970#PowerPC_970MP>

"PowerPC 970MP
IBM announced the PowerPC 970MP, code-named "Antares", on 7 July 2005 at the 
Power Everywhere forum in Tokyo. The 970MP is a dual-core derivative of the 
970FX with clock speeds between 1.2 and 2.5 GHz, and a maximum power usage of 
75 W at 1.8 GHz and 100 W at 2.0 GHz. Each core has 1 MB of L2 cache, twice 
that of the 970FX. Like the 970FX, this chip was produced at the 90 nm process. 
When one of the cores is idle, it will enter a "doze" state and shut down.[5] 
The 970MP also includes partitioning and virtualization features.[6][7]
The PowerPC 970MP replaced the PowerPC 970FX in Apple's high-end Power Mac G5 
computers, while the iMac G5 and the legacy PCI-X Power Mac G5 continued to use 
the PowerPC 970FX processor. The PowerPC 970MP is used in IBM's JS21 blade 
modules and IBM Intellistation POWER 185 workstation.
Due to high power requirements IBM has chosen to discontinue parts running 
faster than 2.0 GHz.

[edit]PowerPC 970GX
The PowerPC 970GX is a cancelled single-core version of PowerPC 970MP. It 
featured a 1 MB L2 cache and would have been available in frequencies of 1.2 to 
3 GHz. Power dissipation would have been 16 W at 1.6 GHz, and 85 W at 3 GHz. It 
was to be fabricated in the same 90 nm fabrication process as the 970MP.[8]"

See Jobs, S "Real artists ship"

Compare this to :

<http://en.wikipedia.org/wiki/Yonah_(microprocessor)>

The original Core Duo used 31 watts max for a dual core processor at 2ghz. The 
IBM 970gx would have had to have been a dual CPU design to match the Core Duo, 
which would have probably put it at 45-50 watts.

So no, the Ars article is not correct, at least in the implication that IBM in 
fact intended to produce truly low-power laptop-capable CPUS in the G5 line.

These were indeed LOWER power than previous designs but for FSM sake those WERE 
the CPUS put into the last gen G5's. Have you ever been into a G5? Seen the 
gargantuan amount of engineering that went into keeping those space heaters 
cool?

NO THEY WOULDN'T. Have you actually USED any Intel-based macs, head to head 
against a PPC system? Even the first MacBooks crushed the previous top-end 
Powerbooks, let along the iBooks they allegedly replaced.

I was there, I've used both, extensively, even running that bodged version of 
10.4 the Macbooks were head and shoulders above the performance of the 
Powerbooks, and with the advent of 10.5 and later 10.6 they were even better.
