Core i7 vs. Phenom II X2 vs. X4 scaling performance analysis
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, 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 both of its expansions are progressively more demanding on your PC graphics and will run slower than the demo. We always run at least two sets of tests with all in-game features at ‘maximum’. F.E.A.R. uses the Jupiter Extended Technology engine from Touchdown Entertainment. We test this game with the most demanding settings. We use fully maxed details with 4xAA/16xAF; soft shadows ‘off’, as they do not play well with AA. Please note that we tossed out our maximums as they are ridiculously high and contribute nothing to the charts. Let’s start first at 2560×1600:
Let’s now check out 1920×1200 resolution with the same maxed out settings:
Now we move on to 1680×1050:
There is not much difference in practically playing F.E.A.R. between the fastest and the slowest CPUs as the minimums are already sufficiently high except for one place where our underclocked Phenom II 955-X4 at 2.6 GHz has difficulty with the minimums with HD 5870 CrossFire. There is also no real advantage of quad-core over dual-core in this aging but still beautiful, DX9 game.
Flat-out amazing!!! I’ve never seen anything so epic like this. So, there was not any microstuttering in any of the above games, where the “measured” 40 fps appeared to look more like “perceived” 25 fps? I guess microstuttering is not noticeable if the measured fps is above 70-80, since half of this (45 fps) would still appear to be relatively smooth. Anything below 30 fps becomes really noticeable, so were there ever 40-50 fps instances with 2x 5870 CF that felt like 25fps or so? I’ll take your word for it, if you were actually watching 10,000 hours worth of benchmarking, ha (just kidding, don’t shoot my head off)!
Surprised there are not more comments. For a single video card it does look like a dual core is more than enough. Sure there are a few games that take advantage of four cores, but the fact remains they remain in the minority.
Bobert, I’ve been saying the same thing for months now.
Wow, very thorough and detailed article. It’s one thing to test CPU performance using a single video card, but it must take some brawn to do it for three different video configurations.
There’s so much data here to look at in so many ways. I suppose if you would have included an SLI setup we would then be able to determine how CPU speed affects SLI vs. Crossfire. If I’m looking at this data right, though, it seems Crossfire sees benefits from quad cores more than single video cards do.
Far Cry 2 seems to be a good example of this. Also Far Cry 2 shows interesting relationships between CPU and the GTX 480. The single HD 5870 doesn’t really react to CPU speed and cores the same way dual 5870s and the GTX 480 do. That’s pretty interesting.
So well done. If I only had one suggestion is that I would like to see GTA4 benched, mainly because I own it and good, thorough, and updated benchmarks of it are not easy to come by.:)
Concerning the Far Cry 2 numbers, despite being beaten with faster processors, the HD 5870 paired with the 2.6 dual core is actually outperforming the Crossfire and Nvidia setup. That’s what I find a bit interesting here.
AWESOME REVIEW.
This is EXACTLY what review websites ARE NOT putting out.
A non GPU-bottlenecked review showing how i7 really does have a significant gaming lead over Phenom II.
God you’d be surprised how many AMD fanboys still believe (and spread rumors) that Phenom II is plenty for 5870 crossfire. Psh. Plenty on today’s games maybe, but that is due to the PC gaming community being SNARED by the noob console community and their half a decade old setups.
Ok I’m ranting.
Two Thumbs!!
Raidur means it shows how Phenom II bottlenecks 5870 crossfire.
Everyone knows i7 is faster in games.
PS. I’m not Raidur.
PSS. I’m Raidur.
PSSS. Or am I?
Awesome review GJ.
Please let me know if you’re looking for a article writer for your
site. You have some really good articles and I believe I
would be a good asset. If you ever want to take some of the load off, I’d love to
write some material for your blog in exchange for a link back
