- by Paul Murphy -
Everyone knows PCs are faster than Macs, but Macs cost more. Right?
There are two issues here: cost and performance. Right now
I want to focus on the cost side of the myth leaving performance for
another column, possibly in late September.
For today, therefore, I'm simply going to argue that Macs and PCs are
optimized for very different kinds of jobs and thus cater to different
perceptions of what constitutes performance. Fundamentally what counts for both is suitability
to purpose, not bits shuffled per second.
That suitability to purpose idea is reflected on the cost side by the Mac's commitment to
multimedia components, such as the SuperDrive and firewire connectivity, missing on the PC. On the
performance side it's reflected in the software supplier's commitment to the Mac with the
general consequence that Macs are faster where the supplier made good use of unique Mac features
such as the true multi-processing capabilities on OS X or the Altivec short array
processor, and PCs are faster for software ported, essentially unchanged, from the PC.

The Macs have built in firewire, airport extreme, and 10/100 ethernet ports along with the OS-X operating system
and a bundle of software including ilife (which Apple describe as "office for the rest of your
life" - GarageBand, iTunes, iPhoto,iMovie and iDVD) and stuff like AppleWorks, Quicken, and the World
Book Encyclopedia.
The PCs come with some variant on Microsoft Windows/XP and varying levels of discount
on Microsoft Office. Thus Office Professional costs $359 on the low end Dimension, $319 on the OptiPlex,
and isn't offered with the Precision bundle.
Oddly, Office Professional for the Mac includes a PC emulator and the package most comparable to
the "Professional" PC edition appears to be called the Standard Edition. It sells at $399 for all Macs.
If we look at these raw cost comparisons carefully it becomes obvious that none of them
really work because the Macs are consistently overspec relative to the PCs.
The entry level eMac, for example, costs $350 (78%) more than the PC but the latter is useable only to run
Windows 98 and other software carried forward from previous generations. Accept Dell's rather
warmly endorsed package of the basic upgrades needed just to run XP comfortably, and the price difference
falls to $190 (24%). That's still considerably cheaper than the eMac, but still short stereo, a R/W
CD/DVD combo, graphics capabilities, wireless connectivity, and dual firewire ports. Adding everything
except firewire brings the price to rough parity but still leaves the PC underspecified relative to the eMac.
The same problems afflict the iMac vs. OptiPlex270 comparison. The base PC is $40 cheaper than the
mid range iMac, but the PC lacks the iMac's connectivity and multi-media capabilities. It's possible
to add these, but doing so pushes the PC well over the high end of the price range for the iMac.
In this case, furthermore, you should be aware that the PC represents Dell's latest product generation while Apple
has just just stopped taking orders for the current iMacs preparatory to introducing the next generation iMacs
in September.
The high end comparison shows the result of the underlying difference in functional focus much more clearly.
Like the iMacs, Apple's current G5 offering is actually well past its intended replacement date because
of IBM's delays in shipping new CPUs, but the basic box is still a full $1,000 bucks
cheaper than Dell's newest Xeons.
As usual, however, the PC lacks the Mac's connectivity features. More importantly, my price comparison above
omits the monitors for both because the recommended monitors are designed for different jobs and are not
remotely comparable. Dell's
"UltraSharp 2001FP 20.1-inch Flat Panel
LCD Monitor with Height Adjustable Stand"
at $899
by itself or $700 if bundled with the Precision 670,
is just a monitor.
Apple's cinema displays are more than that. They're intended to function at the core of digital production environments.
Thus all three models, from the 20 inch to the 30 inch, have things like DVI and dual firewire ports to enable plug and go
video recording or media sharing. In consequence the price ranges from $1,299 to $3,299, or $600 more than Dell
wants for the 20 inch unit, but the additional things they do can't be done with the Dell at any price.
The least unfair comparison, therefore is obtained by adding the Dell monitor, as the lowest common
denominator, to both machines, thereby penalizing Apple's price by the $199 difference between Dell's
stand-alone and package price. Do that and the Mac comes in at $3,898 with the Dell at $4,709 -making the
Apple about 20% cheaper despite offering more features.
At the low end, therefore, the PC desktops are marginally cheaper than the Macs if you can do without
their connectivity and multi-media capabilities and considerably more expensive if you can't. At the
very high end, however, all of the design focus is on multi-media processing and the PCs simply aren't
competitive from either hardware or cost perspectives.
Servers
|
Price |
Configuration |
Apple X-Serve |
$4,399 |
2GB, 160GB, 2 x 2Ghz G5, unlimited users; MacOS-X |
Dell 2850 |
$9,370 |
2GB, 2 x 73GB, 2 x 3.2Ghz Xeon, Windows 2003/XP Server 25 users |
Sun V20Z |
$5,699 |
2GB, 2 x 73GB, 2 x Opteron 248, Solaris x86 |
Note that the Dell 2850 is a brand new machine while
the X-serve is at the end of
its product cycle with the replacement delayed only because IBM has been slow to
deliver the higher speed CPUs.
More importantly, the X-serve is designed for a very different role
than the PC. It runs Unix and so can do anything the PC server can, but the design
optimizations aim at work the PC is very poorly suited to - streaming out multi-Gigabyte digital imaging
files. Thus it has additional
connectivity and a matching X-serve RAID array aimed at completing the package needed
by digital media developers.
Thge X-serve RAID package uses very large, and individually slow, ATA style drives in parallel
to offer cheap ($10,999 for 3.5 TB) bulk storage for large multimedia files that are
usually stored and retrieved via serial I/O. For this type of application what counts most
are reliability and sustained I/O streaming - requirements that are met very well
by a design combining RAID protection with highly parallel ATA.
Dell doesn't offer an X-serve RAID equivelent and the 2850's PC design is not internally
well suited to continuous sequential I/O. Instead it's optimized for short, but high speed,
I/O bursts of the kind associated with document or database storage and retrieval.
The killer issue, however, on comparing Apple's X-serve to the Dell 2850 is that
Apple doesn't charge for client access rights. As a result the
Dell 2850, which costs nearly 30% more than the X-serve before software,
costs more than twice as much as the X-serve once Microsoft's $3,295
charge for a 25 user license gets counted.
At the server level, therefore, a less unfair comparison would be to the Sun V20Z. Sun's
machine, like Apple's, is 64bit capable, has page protection, runs Unix, and provides
for full SMP. For roughly similar dual CPU, 2GB units, with Unix Sun wants about $1,250 bucks more than
Apple with most of that difference accounted for by Sun's use of
UltraSCSI 320 I/O in place of serial ATA.
Interestingly, strip out the OS and Sun's hardware is about $600 cheaper than Dell's - include OS licensing
for access by fifty general office users and you can buy both competing servers for the price
of one Dell 2850.
Notebooks

Inspiron 700M, 1.6Ghz PM, 256MB, 60GB, Intel Extreme Graphics; XP Professional |
Apple 12" |

Powerbook, 12", 1.33Ghz, 256MB, 60GB; NVIDIA GeForce FX (64MB) |

Apple 15" |
$2,499 |
Powerbook 15", 1.5Ghz, 512MB, 80GB; Radeon 9700 (64MB) |
The notebook comparisons are comparatively clean and decisive. Dell's low end Inspiron 5150 ($1,079 after 10% discount)
offers a 15 inch display but is otherwise not competitive with Apple's 12 inch iBook ($1,099) and Dell doesn't offer
anything to compete with Apple's 17 inch Titaniums ($2,799) at the high end.
In between both Apple's 12 inch and 15 inch powerbooks are cheaper and include more extensive connectivity capabilities than
do the PCs.
Summary
So, bottom line, are PCs cheaper than Macs? No, despite what you read in the PC press, it's the other way around:
compare Apples to apples, and Macs are cheaper than PCs.
