Core i7 vs. Phenom II X2 vs. X4 scaling performance analysis
Aliens vs Predator 
Aliens vs. Predator, known to fans as Aliens versus Predator 3 or AVP3 is a video game developed by Rebellion Developments, and published by Sega in February 2010. It is the sixth game of the Aliens versus Predator game series. There are three campaigns in the game, one for each race or faction (the Predators, the Aliens and the Colonial Marines), that form one main storyline although they differ in objectives depending on your choice of campaign.
Alien vs Predators DX11 benchmark is a stand alone bench that as the name says is only for DX11 cards. First we bench at 2560×1600 with maxed out settings plus 4xAA.
Now we test at 1920×1200.
Finally we test at 1680×1050:
This stand alone DX11 benchmark is more demanding generally than the game. However, at the extreme settings we have picked, it is again completely GPU bound. The video card primarily determines the framerates as long as the CPU is sufficient – in this case, a dual-core Phenom II 550 X2 at 2.6 GHz is enough to keep HD 5870 CrossFire as playable as with the Core i7-920 clocked +1000 MHz higher!
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.
