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.

    OK, just one question: why in the hell are the IGP memory tests done on an i7? The results would be much more meaningful if the tests were on an AMD A10 or similar - it has a beefier IGP, and thus would be more bandwidth-bound. Reply

    100% Agree. Doing these tests against a Trinity APU would have been much more interesting from a iGPU point of view. It it well known that AMD APUs benefit from increased memory bandwidth, AT has yet to test Trinity for this yet they did it for Llano. Reply

    It makes sense to test; HD 4000 is far superior to HD 3000 and it is worth knowing if that extra power is bandwidth limited. Generally, it is a little, though nowhere near as much as AMD's equivalents are. Reply

    Not to mention, it's surprising to me that AMD wasn't mentioned as a company trying to match memory to motherboard. AMD started making their own memory modules, an interesting fact I think. Reply

    Maybe because more people use intel? I agree that it would have stood out more if it was AMD's IGP, but doing the test on intel IGP is also okay and gives an idea of what to expect. I think the article is fine. Besides, do people really play games with IGP? If I am playing demanding games, I want the frame rates to be minimum 60 fps. That's why I use a dedicated graphics card. This might change when AMD's IGP gets even more powerful, but for now I think it's still not there yet. Reply

    > Besides, do people really play games with IGP?

    Some of us do. My miniitx i7 is primarily for work & everyday use, but its HD4000 is fast enough for Portal 2 and Diablo 3 to be very playable @ 1920x1080p with AA off.

    However, I know the limits of IGP, and intend on upgrading to an overclocked GeForce GTX 650 Ti very soon in order to play some more demanding games this winter.

    you may want to reconsider your choice of video "upgrade"
    nvidia's 2nd number is more significant than the first as far as overall gaming graphics power goes... You'd do better going for a 560 TI than a 650 for approx the same cost

    You should first look at what chip actually powers the card -and it's capabilities- before staring yourself blind on the last two digits. Besides that, a GTX 560 Ti is more expensive than a GTX 650. Reply

    "Besides, do people really play games with IGP?"

    They're definitely more likely to play games on a more powerful IGP like AMD's. I thought the whole point of AMD's Fusion lineup was that you could do light gaming on the IGP itself.

    There are already plenty of benchmarks out there for memory scaling on AMD's APUs. This is the first time I've seen an in-depth look at how memory speed affects Intel's IGP performance. Reply
