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.

    "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."

    No tangible gains above four gi-... what industries have you worked in? Because my old AdWords PPC company's software benefited from over 4GB, and that's the lightest workload I've had on a computer in a while. For home use, I just bumped my system to 16GB because I kept capping my 8GB, and I do zero video/photo work. If you just do word processing, I'll trade you a nice netbook with a VGA out for whatever you're using now.

    DDR3-1333 to 1600 is almost the same price on Newegg, and 1866 isn't much more. Think about it in percentage cost of your computer. Using current Newegg prices for 2x4GB CL9 DDR3, a $1000 computer with 8GB DDR3-1333 will cost $1002 with DDR3-1600, $1011 with DDR3-1866, and $1025 with DDR3-2133. Not exactly a crushing difference.

    Why isn't XMP enabled by default? The BIOS should know what the CPU supports, shouldn't it? Reply

    What this article glosses over is that G.Skill memory often recommends manually increasing the voltages when enabling XMP profiles. I have the F3-1866C10D-16GAB kit and G.Skill recommends pushing the memory controller voltage out of spec for Ivy Bridge in order to enable XMP. As a result I just run them at 1333 (they don't have 1600 timings in the SPD table and I can't be bothered experimenting to find a stable setting). Reply

    I did not have to adjust the voltage once on any of these kits. If anything, what you are experiencing is more related to the motherboard manufacturer. Some manufacturers have preferred memory vendors, of which G.Skill may not be one. In that case you either have to use work arounds to make kits work, or wait for a motherboard BIOS update. If you have read any of my X79 or Z77 reviews, you will see that some boards do not like my 2400 C9 kit that I use for testing at XMP without a little voltage boost. But on the ASUS P8Z77-V Premium, all these kits worked fine at XMP, without issue.

    While interesting from a theoretical standpoint. I would have been more interested in a comparison in laptops using HD4000 vs A10 to see if one is more dependent on fast memory than others. To be blunt, I dont really care much about the IGP on a 3770K. It would have been a more interesting comparison in laptops where the igp might actually be used for gaming. I guess maybe it would have been more difficult to do with changing memory around so much in a laptop though.

    The other thing is I would have liked to see the difference in games at playable frame rates. Does it really matter if you get 5.5 or 5.9 fps? It is a slideshow anyway. My interest is if using higher speed memory could have moved a game from unplayable to playable at a particular setting or allowed moving up to higher settings in a game that was playable.

    RAM by definition is Random Access which means no matter where the data is on the module the access time is the same. It doesn't matter if two bytes are on the same row or on a different bank or on a different chip on the module, the access time is the same. There is no sequential or random difference with RAM. The only difference between the different rated sticks are short/long reads, not random or sequential and any reference to random/sequential reads should be removed. Reply

    You're joking right? :p Reply

    Well if the next commenter below says their memory knowledge went up by 10x they probably believe RAM reads are different depending on whether they are random or sequential. Reply
