Final Words

The balance between GPU and CPU performance isn't all that matters to World of Warcraft. Memory size is also a very important factor in building a smooth running WoW box.  As with any high end gaming box, less than 512MB of memory is simply unacceptable for WoW. However, the requirements here are a little more strenuous than usual.  We found that ideally, you need 1GB of memory to have WoW running on a machine that has other applications running in the background. While you can get by with less than that, for the best overall performance, the sweet spot is 1GB.  With memory prices at the lowest that they will be for the next few months, making that 1GB or more upgrade is a bit easier now than it was before or than it will be later on.

Blizzard has also done a good job of providing Mac support for World of Warcraft. In fact, the same discs used to install the PC version will work in installing the Mac version of WoW.  Unfortunately, Mac WoW performance is nothing to write home about.  Performance on a dual G5 2.5GHz with an ATI Radeon X800 XT Mac Edition is less than half of the performance of a single Athlon 64 4000+ and a Radeon X800 XT.  The performance on slower video cards is just as disappointing.  Blizzard has been active in improving Mac WoW performance, but the gap remains to be nothing short of huge.  Mac OS X has never been known as a gaming platform of choice, but Mac users should at least be able to run the games to which they do have access at comparable frame rates to their PC counterparts.  Regardless of whether the Mac WoW performance issues are the fault of Apple, Blizzard or the GPU vendors, they need to be fixed if any of the responsible companies actually care about that user base.  WoW is quite playable on the Mac - it's just noticeably slower than on the PC. 

From an overall standpoint, World of Warcraft is much more demanding of a game than it seems.  The game is quite playable on older hardware, and visually, it looks very similar even on DX8 class GPUs, but higher resolutions and getting rid of irritating choppiness when rotating your camera in the world are both enabled through faster GPUs and CPUs. 

WoW is generally more GPU limited than CPU limited, but you still need a relatively fast CPU.  On the AMD side, the Athlon 64 3500+ continues to be the sweet spot, while the Pentium 4 650/550 is the more balanced choice for Intel folks.  And as always, we found that the Extreme Edition is a waste of money.

But if you happen to have a relatively new Athlon 64 or Pentium 4 system, you're pretty much good to go. The biggest need for a CPU upgrade will be lower clocked Northwood and Athlon XP based systems. 

As far as GPUs go, the more you spend, the higher the resolution that you can run and the smoother that things will be at that resolution.  The ATI vs. NVIDIA decision is really up to you for most GPUs except at the lower price points, where the 6600GT and the 6200 both outclass their ATI competitors.

If you're one of the 1.5 million people who has found themselves addicted to World of Warcraft, you might as well feed your hardware addiction at the same time, right?

    did you check the motherboard specs on that computer?
    when i was looking at them to get one for my girlfreind the motherboard didnt have an agp or pci-x slot for an addon video card.
    i could be wrong though...

    Typo on pg 4. "Thankfully from a performance perspective, the Radeon 9800 Pro behaves very similarly to the X700 Pro (a big slower, but nothing huge)"

    Thanks for the article, I would however have one comment.

    The test itself does not show it, but in practice the game is quite CPU dependant, especially in areas where it counts - when the game gets crowded.

    My resoning behind this is that when I'm increasing or decreasing resolution by one step, performance difference is always minimal in any realistic scenario.

    I'm not sure how to test this, though. Maybe if you could stuff a full raid (40 ppl) in some corner of the game. I'm quite sure CPU dependancy would then be MUCH more pronounced.

    "I'm all about getting a lot of bang for the buck and here's what kind of system I chose to get"
    -Well, you shouldn´t buy a Dell.

    Anand, great review. I had to build a PC for EQ2 some time ago and couldn´t find any benchmarks. This WoW benches would have helped. Thank you!

    What I don´t understand is why Blizzard offers no benchmark for WoW. It would be very usefull. I thinks your benches are like the flyby UT-bench (though it´s not your fault - anything else is impossible for you), but a botmatch-like bench would be more interisting. I guess Blizzard could build a good benmark level with ease.

    Oh, one more question. Why don´t you write anythink about the command rate (1T or 2T) you used - it´s quite important! And if I remember correctly a tRas of 10 is not optimal for NF4 boards. I think its 7 or so. Possibly there are similar problems with the P4-setup.

    I almost thought that was a downgrade until I read you plan on adding memory/video. Not too bad a deal but I almost feel compelled to ask "why?" when its not significantly different than your previous system. Im still using the same XP 2400+ for ages yet get a consistent 30+ fps just about everywhere (discounting large towns where it will drop to 15, but still... what kind of computer does good in Ironforge when there are 50 chars on screen?). No jittering at all.

    Great article. This was exactly what I had been wanting to know, but it came 1 day too late, as I've already ordered a system without any recommendations.

    I am on a two year old 2500+ XP Barton with 512 MB PC2700, 80GB 7200RPM 8MB Cache, Radeon 9700 Pro system. General gaming away from many players is smooth, but going through the Crossroads, Origrammar, Ironforge, and flying on a gryphon/wyvern would be terribly choppy. I would guesstimate where I would run by holding down the movement keys during lag and then wait a second for an update and continue until I did what I had to.

    It is also a pain to alt+tab out to use Thottbot, which is why I so rarely use it... (I end up being the one of the newbs to beg in /1 (general chat) for hints).

    Along with the new system I've bought, I ordered extra RAM (2x512 Cosair Value Select $93 shipped from Chiefvalue.com) in order to multi-task better. And plan on looking up a good priced 6600 GT card.

    I'm all about getting a lot of bang for the buck and here's what kind of system I chose to get:

    Dell just had a good deal going, considering the $150 MIR ($600 cost). It's like getting the monitor for $300, processor $200, HD $50, Mobo $50 and everything else free (Windows XP Home, Printer, Memory, CD-RW drive, KB/M, software, and Dell's support).

    Just a quick FYI: Level of Detail (LOD) has nothing to do with the textures. LOD is a ploygon scaling algorithm, so as you get closer to an object more polygons will be added to make it look more realistic. Done properly, it should be hard to spot. Unfortunately, doing LOD properly is very difficult.

    With the high-end GPUs, polygon performance generally isn't enough of a problem to make enabling LOD necessary. Lower end CPUs and GPUs can benefit, of course. In the past, I've seen LOD have less than a 10% performance impact, so I'm happier leaving it enabled in most games. (Not that most games actually expose LOD as a tweakable setting....)

    I wholeheartedly agree with the Mac statements after playing it on a Mac myself. I have a 12" PowerBook Rev. A(867mhz G4, GF4 MX420, 640MB RAM, etc), and the performance I get out of WoW while on the road is abysmal(single digit frame rates when more than a handful of characters are on the screen). Just for comparison's sake, I loaded up WoW on a somewhat similar PC(AXP 2100+, GF2MX original, 768MB DDR, etc), and there's simply no comparison between the two; just eyeballing the FPS has the PC at well over 2x the performance. I even managed to isolate the CPUs in all of this, with the PowerBook almost never hitting 100% CPU utilization in this test(it hovered around 80% or so), meaning the PowerBook should have the edge over the PC, but as I stated before it was losing badly.

    I have a feeling a lot of this has to do with the fact that the Mac version is using an OpenGL renderer while the PC is using DirectX, but still 50% is insane. It beats not having WoW at all, but there's still some sort of large bottleneck in there, and I'm fairly sure it's all related to the graphics subsystems.

    I too would like to see a review like this for Everquest II. I don't play WOW and have not seen its graphics first hand but from the looks of the cards\resolutions that are being used in this review... Everquest is putting a lot more stress on the cards. I know that every video card I have seen thus far will crawl to a halt with the graphics turned up to Extreme Quality at 1280x1024. It would be very interesting to see where the bottle necks are and what card would do the best in this scenario.

    When measuring fps, could you also show the most common lowest fps achieved?

    I want to see what the lowest will be, if I upgrade my hardware.
