i-RAM for Gamers

Although you definitely need more memory if your game is pausing during gameplay to swap to disk, level load times can be very annoying, especially with the excruciatingly long load times of some recent popular titles such as Unreal Tournament 2004 and Battlefield 2. So, what about using the i-RAM as a "game drive" to store whatever game you happen to be playing the most at the time, and hopefully reduce those pesky load times?

So, we went to test a handful of games, Splinter Cell 3, Doom 3, Battlefield 2 and UT2004, and in that quest, we ran into our first problem - UT2004 required around 5GB of space to install, and we only had 4GB on our i-RAM. The rest of our tests proceeded without a problem, but the capacity issue is one that was an underlying theme of our testing with the i-RAM: its Achilles' heel is its capacity limitation more than anything else.

Most of the games that we installed on the i-RAM occupied between 1GB and 3.5GB of space, but we wouldn't put it past many developers to begin pushing those limits very soon, if they aren't already. But then again, you could always add another i-RAM later, so how'd it fare in the games we could install on it?

Game Level Load Time Comparison (Lower is Better)
Splinter Cell: CT
Doom 3
Battlefield 2
Gigabyte i-RAM (4GB)
8.0s
19.6s
20.83s
Western Digital Raptor (74GB)
10.59s
25.78s
25.67s

First off, we had Splinter Cell 3 - we ran the lighthouse benchmark that ships with the game and timed the loading screen for the level. The Raptor came in at just under 11 seconds, while the i-RAM came in at 8 seconds. Not a huge improvement, and honestly not overly noticeable (other than the fact that there was no disk crunching), but it was a measurable difference.

Doom 3 proved to be a bit more appreciative of the i-RAM's efforts; the Raptor came in at just under 26 seconds, while the i-RAM loaded the first level in 19.6 seconds. Again, if you were expecting the load time to drop to instantaneous, that's not going to happen, but the reduction in this case was quite measurable.

Our final test was the big one - Battlefield 2. For this test, we used our benchmark level and once again, timed the ever-so-long loading screen. The Raptor got us out of that screen in 25.67 seconds, and the i-RAM did it in 20.83 - a similar performance gain to what we saw in Doom 3.

Overall, we saw some reasonably tangible performance improvements in game level load times - but nothing we would characterize as spectacular. For the money, you're much better off buying a better video card to improve your gaming performance; but if you happen to already own a pair of GeForce 7800 GTXes, then maybe an i-RAM is in your future.

    i thought they said that they were only going to make 1000. enought for the crazies who have money to burn...
    P.S. if any of you crazies are reading this i could burn some of that money for you... just let me know.

    Thanks for running through the multiple roles for which the iRam might be useful. I'm rather surprised it wasn't MORE useful in the benches. I'd be interested in learning (i.e. slacking back and reading the results of someone else's research) why the i-Ram is still as large a bottleneck as it is. Yes it's faster than the HD, but why isn't it much, much faster? Are we seeing OS inefficiency or something else altogether?

    In the end, though, it doesn't fit my needs particularly well, so I'll pass this round. Maybe a future version will be more appealing in terms of cost, speed, size.

    maybe the SATA interface isn't fast enough?

    I'm constantly shuffling 1--3 gb mpeg2 files around...this would be great

    Would it be possible for an NVIDIA or ATI graphics card that used TurboCache or HyperMemory to make use of the i-RAM?

    That might be interesting.
  • Anton74 - Monday, July 25, 2005 - link

    No, absolutely not. Even if it were, the SATA interface is *way* too slow to be of use for something like that.

    And even if that were not a factor, why spend that kind of money on the i-RAM where the same amount would buy a *much* superior video card with its own dedicated memory?

    I think that this would be very helpful as a page file for workstations. Older workstations may be maxed out with 4GB and windows 2000 (which the company does not want to move over to xp-64) and still need additional ram for CAD/CFD/etc. This would be an easy upgrade with a reasonable amount of performance increase.
  • sandorski - Monday, July 25, 2005 - link

    Was hoping it would offer more, especially as a Pagefile. Any plans to make a PCI-e version(IIRC PCI-e has a ton more bandwidth than SATA), that would likely make this a Must-have. As it stands now I'd only use it for the silence in a HT Setup.

    Using PCI/PCI-e for transfers would require OS drivers which wouldn't be available for all OSes.

    Keep in mind that for many years the ide/sata controllers are NOT on the PCI bus of the southbridge, so PCI is not a limitation.
