Do You Really Need More Than 6 GB Of RAM?

Benchmark Results: 3D Games

Play-by-play benchmark comments are needed whenever inconsistencies are found, but that didn’t happen with the game tests of today’s article. We thus grouped all of these together on a single page to show an overall pattern.

Single-task gaming doesn’t require anything more than 3 GB to achieve full gaming performance, even at high resolutions and details. Of course, the key here is single-task. We heard your comments in the 64-bit story, requesting multi-task testing, and that's coming later. For now, what about applications?

  • Try opening a PSD file from a 21-Megapixel camera with 3 or more layers in Photoshop and see the difference.

    It's generally accepted that XP uses less RAM than Vista, so you should be fine with 4GB (which, with 32-bit XP, will yield around 3GB of usefull address space).

    Hey guys I was wondering: What if you had a 9g game loaded completely on a ramdrive (64bit+software) then kept the remaining 3 for regular ram?

    It looks like a memory testing machine or burn-in rack to me...I'm not sure where the site found it.

    That's a great idea! Because it takes sooo long to copy an entire game from the hard drive to "anything" (even RAM), most users won't even try it. But you would get super-fast map loads!

  • Try using several VMs in parallel and you'll be happy to have more than 3 GB. I'm using one VM for work (image of my work notebook with VPN etc.) and one for online banking (mainly because my old smartcard isn't supported in 64bit OS, little bit of a catch22).
