Quad Core vs Dual Core: Q9550S vs. E8600, Part III – CPU Scaling with CrossFire
F.E.A.R.
F.E.A.R. – First Encounter Armed Assault – is a DX9c game by Monolith Productions that was originally released in October 2005 by Vivendi Universal Production. Later, there were two expansions with the latest, Perseus Mandate, released in 2007. Although the game engine is aging a bit, it still has some of the most spectacular effects of any game. F.E.A.R. showcases a powerful particle system, complete with sparks and smoke for collisions as well as featuring bullet marks and other effects including “soft shadows”. This is highlighted by the built-in performance test, although it was never updated. This performance test will tell you how F.E.A.R. will run, but its first and second expansions, Extraction Point and Perseus Mandate, are more demanding on your PC graphics and will run slower than the demo. We always run at least 2 sets of tests with all in-games features at ‘maximum’. F.E.A.R. uses the Jupiter Extended Technology engine from Touchdown Entertainment.
We test with the most demanding settings. Fully maxed details with 4xAA/16xAF; soft shadows ‘off’, as they do not play well with AA; first at 1920×1200:
Finally we test at 1650×1080 with 4 AA/16xAF and with Soft shadows again disabled:
Quad core wins. Here the E8600 drops its mimimums into the high-20s to finally match our stock-clocked quad; even when our dual-core is overclocked to its maximum.
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.
