Quad Core vs Dual Core: Q9550S vs. E8600, Part III – CPU Scaling with CrossFire
Enemy Territory: Quake Wars
Enemy Territory: Quake Wars is an objective-driven, class-based first person shooter set in the Quake universe. It was developed by id Software and Splash Damage for Windows and published by Activision. Quake Wars pits the combined human armies of the Global Defense Force against the technologically superior Strogg, an alien race who has come to earth to use humans for spare parts and food. It allows you to play a part – probably best as an online multi-player experience – in the desperate battles waged around the world in mankind’s war to survive.
Quake Wars is an OpenGL game based on id’s Doom3 game engine with the addition of their MegaTexture technology. It also supports some of the latest 3D effects seen in today’s games, including soft particles, although it is somewhat dated and less demanding on video cards than many DX10 games. id’s MegaTexture technology is designed to provide very large maps without having to reuse the same textures over and over again. For our benchmark we chose the flyby, Salvage Demo, from Enemy Territory:Quake Wars. It is one of the most graphically demanding of all the flybys and is very repeatable and reliable in its results. It is fairly close to what you will experience in-game. All of our settings are set to ‘maximum’ and we also apply 4xAA/16xAF in game.
Salvage Demo fly-by at 1920×1200:
Now at 1650×1080 resolution:
No contest! Quad core scores significantly higher across-the-board – yet there is no place where E8600 would be considered slow with this game even at 1920×1200. You might consider enabling CrossFire filtering.
Great article. Here’s what I found most interesting
If we just look at the minimum framerates for the chips are similar clockspeeds (Q9550s @ 3.4 vs E8600 @ 3.33 and Q9550s @ 4.0 vs E8600 @ 4.0) the quad core comes out on top the majority of the time.
For the two-way Xfire tests, the Q9550 (at similar clockspeed to) beats the E8600’s minimum framerates in COD4, UT3, Lost Planet, HL2: LC, FEAR, ET: QW, WiC, FC2, and PT Boats. The two chips, for the most part, tie in the games Stalker, Crysis, and X3. The only game where the quad loses is Call of Juarez.
When we look at the three-way XFire tests, the results are basically the same except Lost Planet and PT Boats moves from the “win” category to the “tie” category for the quad core.
I wonder what’s up with the Call of Juarez results. Even with the chips at the same clock speed, the quad core loses fairly significantly. At 4.00 GHz, the quad’s minimum framerate is 31 while the dual’s is 42.
I wondered about CoJ as i was testing and repeated those benchmarks many, many times; far more than with any other of my tests. I would say that some of it is probably partly because of the Cat 9-2 drivers. If you look back on this benchmark to our September testing with Cat 8-1 all the way through Cat 8-12hotfix, there is definitely some variance with multi-GPU performance.
So let me theorize that there appears to be a ‘hitch’ in CoJ – you can actually watch it “stutter” in a couple of places – that the slower clocked Quad simply cannot overcome that appear to really skew the bottom [and thus average and max] framerates. It exaggerates what happens when you actually play CoJ, similar to my old STALKER benches that had way too high of a maximum as they panned the sky. The CoJ benchmark was also never updated, although the game was. That makes it somewhat flawed in my opinion, as the vendors are continuing to optimize for the game, not for the old benchmark. In the future, it will not be so important – as for example, in my current benching, “Vista 64 vs. Vista32-bit”, my Q9550s is at 4.0Ghz where this is not observed quite so much.
It also means that I am considering making a custom timedemo from the latest patched CoJ. I wish Techland would update theirs. Or maybe I will wait for “CoJ 2, Bound in Blood” and use that new benchmark instead. I am looking forward to its release, soon.

they say 1-3 weeks, but that is not official. The trailer says, “Summer”.
Here is a trailer on You.Tube:

You also need to realize that CrossFireX-3 is still imperfect; you can see it’s scaling is still not “bang-for-buck”. Clearly there has been drastic improvements overall in the CFX-3 Catalyst drivers over the last 6 months, but there is plenty of room for more.
Yep, I can’t wait to see how multi-core CPUs and GPUs take off this year. Check out the following results for the new Tom Clancy game:

Those were some of the most striking results I’ve come across yet – even more striking than GTA4.
Hey you I’m a big fan of your blog. Hope you keep updating it regularly.
