Portal 2

A stalwart of the Source engine, Portal 2 is the big hit of 2011 following on from the original award-winning Portal.  In our testing suite, Portal 2 performance should be indicative of CS:GO performance to a certain extent.  Here we test Portal 2 at 1920x1080 with High/Very High graphical settings.

Portal 2 IGP, 1920x1080, Very High, 8xMSAA

Portal 2 mirrors previous testing, albeit our frame rate increases as a percentage are not that great – 1333 to 1600 is a 4.3% increase, but 1333 to 2400 is only an 8.8% increase.

Batman Arkham Asylum

Made in 2009, Batman:AA uses the Unreal Engine 3 to create what was called “the Most Critically Acclaimed Superhero Game Ever”, awarded in the Guinness World Record books with an average score of 91.67 from reviewers.  The game boasts several awards including a BAFTA.  Here we use the in-game benchmark while at the lowest specification settings without PhysX at 1920x1080.  Results are reported to the nearest FPS, and as such we take 4 runs and take the average value of the final three, as the first result is sometimes +33% more than normal.

Batman: AA IGP, 1920x1080, Ultra Low

Batman: AA represents some of the best increases of any application in our testing.  Jumps from 1333 C9 to 1600 C9 and 1866 C9 gives an 8% then another 7% boost, ending with a 21% increase in frame rates moving from 1333 C9 to 2400 C10.

Overall IGP Results

Taking all our IGP results gives us the following graph:

The only game that beats the MemTweakIt predictions is Batman: AA, but most games follow the similar shape of increases just scaled differently.  Bearing in mind the price differences between the kits, if IGP is your goal then either the 1600 C9 or 1866 C9 seem best in terms of bang-for-buck, but 2133 C9 will provide extra performance if the budget stretches that far.

    That's what I was thinking as well.
    I'm hoping for another article using Trinity. :)

    I'm not sure A10 supports DDR3-2400 (DDR3-1866 was the fastest memory supported) Reply

    The A10 has AMP profiles(Like XMP on Intel) up to 2133MHz, however, there's always overclocking, I'm pretty sure Ivy Bridge doesn't suppoort 2400+MHz memory natively either. I'm looking at an FM2 board by Asrock which they claim can support 2600MHz memory. Reply

    My A10-5800K sort of liked DDR3-2400, then it didn't like it. Had to go back one to 2133 for the testing. Even with bumped voltages and everything else, the CPU memory controller couldn't take it. Perhaps the sample I have is a dud, but that was my experience.

    I concur.

    Pointless review anyway. The summary should have read: High-Clocked Memory only needed if your primary usage is either competitive benchmarking or WinRAR compression.

    Did you know that before you read the article though? This is Anandtech, and I like to think I test things thoroughly enough to make reasoned opinions and suggestions :) Having a one sentence summary wouldn't have helped anyone in the slightest.

    Love this article first time I ever commented on one. I believe you see little improvement past 1600/1866 because the Intel chips on die cache do a good job of keeping the CPU fed. Meaning the bottleneck on an Intel chip is the CPU itself not the memory or cache.

    Can you do this with an AMD chip also as I believe we would see a bigger improvement with their chips because the on die cache cant keep up with the chip and faster external memory would give bigger performance jumps for AMD chips. Well maybe 2 generations ago AMD but lets see your pockets are deeper than mine.

    Hope I said that right I'm a little droopy eyed from lack of caffeine.

    Just bought RipjawsZ from Newegg for $90 after coupon! I feel vindicated in my choice now :) Reply

    I thought the performance difference would be less than it was. Has me rethinking whether I need to update my old OCZ DDR3-1333 chips. I haven't yet, as I'm probably giving away 5-10% performance in my OC alone. I targeted efficiency, not absolute speed - at 4GHz my i7-920 D0 consumes 80W less @ idle than the default settings of my mobo - go figure.

    For typical desktop use with RAM frequencies of 1333 MHz. and higher there is no tangible gains in SYSTEM performance to justify paying a premium for higher RAM frequency, increased capacity above 4 GB. or lower latencies - with APUs being the minor exception.

    In real apps, not synthetic benches, there is simply nothing of significance to be gained in system performance above 1333 MHz. as DDR3 running at 1333 MHz. is not a system bottleneck. Synthetic benches exaggerate any real gains so they are quite misleading and should be ignored.
