February 18th, 2005 -- Check out our NEWEST TEST PAGE comparing the Dual Xeon 3.4GHz, Dual Opteron 252 (2.6GHz), Athlon FX55 (2.6GHz), and G5/2.5GHz Power Mac.
This is article is technically obsolete but we're leaving it up in case you are interested.
OF CPU INTENSIVE TESTS
The G5 is touted by Apple is the "World's Fastest Personal Computer." Though we haven't fully tested the Dual Xeon 3.06, we were able to post the Cinebench 2003 results for it. It edged out the fastest G5.
What's interesting is the fact that the dual processor G5/2.5GHz blows away dual processor Xeon 2.4GHz. In other words, here's two dual processor machines running at about the same clock speed. Yet, the G5 wins. That gives Mac fanatics something to cheer about.
PC fanatics can cheer about the fact that there are PCs running at over 3GHz. In fact, we should have full test results on a Dual 3.06 Xeon and Dual 2.5GHz Opteron within two weeks.
The Dual Athlon 2600+ (2.1GHz) system had 1GB of DDR memory and ran Windows XP Professional.
The Dual 2Ghz Opteron system had 2GB of PC3200 DDR (cas 2) memory and ran Windows XP Professional. (We hope to test this once a 64 bit version of Windows has is available and fully supports our test software.)
The Opteron system was provided for testing by XiComputer.
The Dual 2.4GHz Xeon system had 2GB of PC2100 DDR (cas 2) memory and ran Windows XP Professional. (Hyper-threading was enabled.)
The 3.0 GHz Pentium 4 system had 2GB of 400MHz PC3200 DDR memory and ran Windows XP Professional. (Hyper-threading was enabled.)

Both the Pentium and Xeon had hyper-threading
turned on. It's an interesting and effective
feature. When running Cinebench 2003 render, the
application "thought" the Xeon had four processors.
And the 3D render speeds with hyper-threading
enabled were as much as 23% faster than when it was
Though the G5 supports multi-threading, it does NOT support hyper-threading.
Apple Power Mac G5 models were borrowed for testing from ProMax, a diigital video integrator for Macs and PCs. They were running Mac OS X (10.3.5). The Dual 2GHz and 2.5GHz G5 each had 2GB of PC3200 DDR (400MHz) memory.
Photoshop 7.01 had the G5 optimized plugin
