Phenom II X3 720BE & CrossFire X Performance - Does it Compete?

Left 4 Dead
This game is a blast and addictive to boot - provided you like killing hundreds of zombies while trying to take care of your teammates and sustaining high blood pressure rates. What we really like about Source engine games is their ability to run well on variety of systems. We enable all options, set AA to 2x and AF to 8x, and play back a custom timedemo of a complete game session from the Runway chapter within the Dead Air campaign.
This title also favors the Intel processors. When comparing the 720BE to the X4 940 at 1680x1050, the 940 holds a 7% average frame rate advantage in single card mode, 4% in Crossfire, and a surprising 3% in the overclocked settings. We matched our stock 720BE clock and NB speeds with the X4 940 to see if the extra core really makes a difference in this game with the multi-core rendering option enabled. It actually did with the performance improvement averaging about 2% on this particular level.
Adding a second card for CrossFire operation improves average frame rates by 17% and minimum frame rates by 8% for the 720BE. Overclocking our 720BE by 35% resulted in a 19% improvement in average frame rates and 26% in minimum frame rates.
No real surprises here; the 1920x1200 results follow the pattern set at 1680x1050 for each platform. The X4 940 holds a 6% average frame rate advantage in single card mode, 7% in Crossfire, and 5% in the overclocked settings. Adding a second card for CrossFire operation improves average frame rates by 14% and minimum frame rates by 27% for the 720BE. Overclocking the 720BE resulted in a 25% improvement in average frame rates and 21% in minimum frame rates.
Our game play experiences revealed no differences between the three platforms. Although the frame rates were lower with the Phenom II platforms, it just did not matter in this game as minimum frame rates were at 60fps or higher in our tests. The 720BE certainly offers more than enough processing power for this title.

What is the need for a 9400M in a carPC? How much GPU does it take to run a front end?tshen83 - Sunday, March 29, 2009 - link
If you haven't figured out by now, both Intel and AMD flush higher TDP CPU parts down the consumer's throats, and save the really good CPUs(performance per watt) for the data centers in the 2P space.My original post was meant to tell Gary Key, the author, that his "paid" assertion that "Phenom is competitive as a gaming platform" is flawed, because all gaming benchmarks are GPU bound. It means CPU can be a lot weaker before it will show up on the FPS charts.
There is no reason to save 30 dollars to get the X3 at all because the X4 is just a dinner bill away from the X3. Have some mac and cheese for dinner and you would have had enough money to get the Phenom x4 920.(Not that it is a smart choice at 125W TDP, but surely beats the X3 by far.)
There are actually far better AMD CPUs to get than the Phenoms. AMD Shanghai 2376s are at the same price now, and allows scalability to 2 Socket and takes only 75W TDP also. Tyan S2912G2NR board is 60 dollars at newegg to support two Shanghais. Phenom x4 is the CPU that didn't make the "Shanghai" grade, and got flushed down to unsuspecting consumers. x3 is a castrated x4. You get the point.
BTW, i7 920 will get far better longevity as a platform than any AMD processor right now. Nehalem-EP would likely bankrupt AMD for good this time(In fact AMD is already broke a few times if it wasn't selling blood to the Dubai oil suckers) Your argument that Phenom IIs will outlast Socket 775 is correct, except in the case of AMD going belly up, then, you are stuck with a 125W TDP heater that's half the speed of the i7-920.
Good luck, I am taking off for the day. Get ready for tomorrow, when Nehalem-EP will be revealed, and it will put AMD out of its pathetic misery.

some bold assertions. care to prove any of those?out of the three tech giants (Intel, nVIDIA, AMD), AMD currently has the best platform: only AMD can deliver the complete package using only their products. this will be a pretty big advantage down the road, and i think Intel and nVIDIA both know this.
therefore, AMD is not going away.

Don't feed the TROLLS.tshen83 - Monday, March 30, 2009 - link
Only AMD can deliver the complete "CRAP" package to idiots pretty much. Let's see, the CPUs aren't as good as the Nehalems. The GPUs get their butts kicked in GPGPU modes. It takes AMD's 800 Stream processors to fight Nvidia's 240. Talk about freaking copy and paste engineering.In the enterprise market, IT managers will soon realize that the glorious AMD days(HP DL585) are gone, and 8 Socket Nehalem-EX will be a 128 thread monster with 1-2TB of ram(128 FB-DIMMs), killing off Itanium(HP Superdome) along the way.
"AMD is not going away". Really? I have AMD's tombstone marked June 2010, with Hector Ruiz's name on it too. The Global Foundry spinoff dollars won't even last them 3 months.

Does the Opteron have unlocked multipliers? I'm thinking no!Repr - Sunday, March 29, 2009 - link
so far the E8x00 series have been the most wanted choice for gaming machines (in the netherlands at least). however after checking a few price comparison sides i found out that the x3 720 is cheaper then the E8400. i would wonder how the tripple core would fight up against the intel dual core.hansmuff - Saturday, March 28, 2009 - link
Thanks for the article.I do have a request: for those games where you use timedemos or other recorded input files, would you be willing to link to them in the article?
It'd be nice to compare one's own machine to those benchmarked.
Thank you!

My guess is they want to keep them closed so "optimizations" don't take place that would give an unfair advantage to one side or the other.Roland00 - Saturday, March 28, 2009 - link
This article was near perfect in what I am looking for in a price for your buck comparison. Showing the difference between cpus at different frequencies, with/without cross fire, and showing the minimum frame rate in an easy to read manner. To top it all off you had real analysis in the text.Well I am glad to know the X3 PhenomIIs are comparable with gaming, with a nice oc and sometimes needing Crossfire.
Then again at the price an X4 PhenomIIs are you may just want to get an X4 PhenomII
Currently newegg has the x4 920 at 164. It has a promo code for 30 dollars ( AMD32530 ). Making the cpu $134 with free shipping and most places no tax.
