Core i7 vs. Phenom II X2 vs. X4 scaling performance analysis
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 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 battles waged around the world in mankind’s desperate 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. It is one of the most graphically demanding of all the flybys and it 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 8xAA plus 16xAF in game. Unfortunately, we lost some of our CrossFire results with Phenom II and will present what we have. First we test at 2560×1600 resolution with all settings fully maxed in-game plus 8xAA/16xAF:
Let’s next test at 1920×1200 resolution.
Finally on to 1680×1050:
Our framerates are pretty consistent except for our Phenom II 550-X2/HD 5870 combination at 2.6 GHz falling way short of its similarly clocked Intel counterpart. Using a single HD 5870, we see almost no difference between Core i7-920 at any of its clocks and the Phenom II, either dual- or quad-core CPUs, at 2560×1600. We do see the Core i7-920 stumble a bit at 1920×1200 compared to the Phenom II 944-X4 that we do not see at 1680×1050, so we can assume it is a quirky driver issue. There is not a lot of difference practically playing with any of our CPUs using either our HD 5870 or our GTX 480 – at any core speed. You can save your money on your CPU platform if you play ET:QW.
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
to mine. Please shoot me an email if interested.
Thank you!
