Hey Guys, I’ve just read all your posts with a great deal of interest. As I mentioned, I’ve just moved houses, and I have some guest staying with me for a while, so it been really hectic and I haven’t really had much of a chance to get online, yet alone write a decent reply (it usually takes me a couple of hours) to all the stuff that’s been going on.
In this post, I hope to address a few things with the G5 vs P4 vs Opteron hardware argument, and to briefly enter into the software argument too.
Before I go any further, I want to say that I really don’t believe (and you shouldn’t either) that a Dual G5 system is 2.2x faster than a Dual Xeon. Before any such claim about a system performance can be believed, real independent testing needs to be done. Apple contracted Veritest to benchmark the G5 against the Dell systems so they aren’t really independent - On the first page of the Veritest report, it says: "Test report prepared under contract from Apple Computer". Every result that you see on the G5’s website is misleading. It’s all outlined here. I don’t really want to repeat too much of what that Author says, but I will give a small snippet.
[quote=”http://www.haxial.com/spls-soapbox/apple-powermac-G5/”] Not ready to be fooled, I found this March 2003 Sharky Extreme article by Vince Freeman. As you can see, Sharky Extreme says they achieved 334 fps, which is much faster than the 275 fps that Apple claims the Pentium 4 3.0 GHz achieves. My suspicions were confirmed: Apple is deliberately attempting to mislead its customers again.[/quote]
Since this is primarily a gaming site, I’ll include this graph from Apple and this quote from the article I listed above regarding Quake3. I think it demonstrates how Apple purposely de-optimized the Intel systems for their tests.
Anyway, we could argue until we are blue in the face about the hypothetical performance of each system. Give it a month until the G5 is in some independent reviewers hands – then we’ll see how it really performs against the P4s and Xeons. And to make thinks even more interesting, we’ll see how it compares in September against the Athlon64 too.
It seems the system I priced before was a bit questionable, and honestly, I just picked the absolute cheapest prices with specs at or above the G5. As Apollo pointed out “…you left out some key components (case, fans, heat-sink, power supply, etc. and all of these things are minor costs)”. It seems I did leave out the Case, Power, etc. when I priced the system. My only excuse is that I’m an idiot and it completely slipped my mind. So I’m going to re-price the system, and try to match a PC machine exactly to the top of the line G5 (the M9032LL/A).
This time I’m going to use brand name pieces, instead of miscellaneous brands, so that should make sure I only get top quality equipment. I will use newegg.com for prices – newegg is renowned for reasonable prices and is a very trustworthy dealer. So without further ado, I present the specs and cost of a new Xeon system that is as identical as possible to the new G5.

Well, I must say that the final price amazed me. Before I started, I assumed the total for a top of the line Dual Xeon system would be much closer to the $3000 mark. Granted, again I left out the case and power supply, but with a $600 margin you can grab yourself a pretty snazzy case and power supply – one that looks similar to an Mac case. Or a generic case and 400watt power supply only cost about $50 these days anyway. And I suppose you might want to add $100 for a copy of Windows XP –although you could use Linux for free. So, the basic conclusion to find from this is that you can build a somewhat comparable Xeon system for quite a significant amount cheaper than a new G5.
But how comparable are the two systems? The Xeon can’t physically support as much ram as the G5 and the 800mbps Firewire port is a Mac exclusive for the time being. The Xeon system I made however does have bonus such as hardware RAID, 2 IDE controllers, and 6 USB2 ports. But for all practical purposes, this system is nearly identical to the top-of-the-line G5 (same ram, HDD, video card, burner, etc…). Note that when I say same Video Card, I mean the chip on the card is the same (ATI send the same Radeon Chips to Manufacturer who then build the controlling boards around them) and thus Video performance is going to be essentially the same.
However, it’s not fair to compare the Xeon to the G5. Let’s face it – the G5 architecture is just superior to the Xeon. The Xeon is based on the P4 architecture, which is in terms of computer hardware, is ancient (the P4 was launched in Nov. 2000). The G5 is Fresh-off-the-Press with the latest and greatest technology inside it – including the AltiVec instruction set, a 1GHz bus, and hyper-transport technology, not to mention being a 64-bit processor. At this time, there really isn’t a consumer chip that can compare to the top of the line G5 (although, its arguable that the top of the line G5 is aimed at professionals not consumers right now).
The only processor for PC on the horizon that is comparable to the G5 is the AMD Athlon64 (Athlon64 is the consumer version of the Opteron). The G5 and the Opteron/Athlon64 are very similar processors, they are both 64-bit and both utilize the hyper-transport memory controller on die. To get cost estimation of an Athlon64 system, I priced a system based on a top-off-the-line dual Opteron.
Stuff from other system minus Processor and mobo = $954
CPU: AMD Opteron Model 244 1.8GHz 64-Bit - $826.00 * 2 = $1652
Mobo: MSI Dual Opteron Processor Server Motherboard - $452
Total2 = $3058
The motherboard I choose isn’t exactly feature rich like the G5’s is, but I think it accurately reflects the price. Until the Athlon64 hits the market, we aren’t going to see nice Motherboards for it that support SATA, Firewire, and 8x AGP pro (although, I’ve never heard of ‘pro’ before. I assume it just gives you more power (watts) to your card? Correct?).
So what conclusion is all this drawing to?
Is the G5 the fastest Consumer Computer on the market?
I doubt it. It’s one of the fastest – the Xeon can still out perform it in many situations if optimized correctly.
Does the G5 have the best Architecture of a Consumer Computer on the Market?
Definitely and with out question – Until the Athlon64 comes out.
Does the G5 give you the Best Performance per Dollar?
Not really. You want the top of the line G5 you have to spend $3k. You can upgrade from your current system to an Athlon64 for about $1500. You can get a brand new Xeon without all the bells and whistles (such as SATA, Firewire, etc) for under $1500 and still have a machine that can outperform a G5 in certain situations.
Is the G5 a good deal?
Depends what you want. For the home user, probably not. For the gamer, definitely not. For the professional video editor – yes!
Should I buy one?
No, wait and see the Athlon64 first.
I still believe that because Apple controls both the hardware and operating system, the Apple systems will run better and more fluidly than the XP systems, just as they do today.
It is for this reason that I compared the Mac to the Xbox. All humor and insults aside, a console or a Mac you have one big advantage over a PC, and that is all the hardware inside has been engineered, by one company, to work optimally with all the other hardware inside the box. Compared to a PC can have parts from dozens of different vendors inside and who have never collaborate with each other to ensure optimization. PC software obviously has to be much more scalable to work on the hundreds of possible different systems configurations, so you are going to loose some ‘fluidity’ in exchange for the scalability. That being said, I find my XP system to be perfectly fluid as it is, and my limited experience with OSX is that it isn’t really anymore fluid that XP is.
Regarding the fairness of Apple Advertising again. Richie snagged us this image from Apples Website
Once again, they’re not comparing Apples to Apples here (excuse the pun). The Mac has beautiful slim Serial ATA cables, where as the PC they’ve pictured uses an ugly mess of wide IDE cables – to be fair they should have compared a PC with SATA too.
I can’t go on writing, I’m exhausted. I’m sorry, I’ve starting to loose my focus and my will to keep writing (plus I have a bunch of people bugging me to come away from the computer). I have to go, but I will come back in about 12 hours and fix the formatting of my post. I do enjoy these mega-post arguments that seem to erupt occasionally on forums. It’s so nostalgic of a big argument between Break, Jack, RU, Siege and I from DDRSTL about the Gamecube… Anyway, I’ll just leave by saying that the G5 is a decent system – if you like Macs.
BTW, Apollo, what’s your story? I don’t believe we’ve really met properly. Are you a student, professional, what? I’m EMP. I’m 19, studying Software Engineering at Newcastle University, Australia, and my favorite platform is the PC.
