Doom 3 Buyer's Guide

Memory for Doom 3

From all the comments that have been posted, there seems to be the unquestioned assumption that more memory will improve Doom 3 performance. The reality is that we have not been able to confirm objectively that assumption. The built-in benchmark for Doom 3, accessed from the console, was used to test common memory amounts on an Intel 875 platform, an Athlon 64 Socket 939 platform, and an A64 Socket 754 platform.

It was surprising that there were no real performance differences between 512MB, 1GB, and 2GB of memory in our benchmarks with the built-in Demo1. The only memory amount that shows lower performance is 256MB on the Socket 754 platform.

Perhaps the built-in Demo1 does not stress the system enough to really reveal performance differences in total memory. We did check memory usage in the console and found Doom 3 used memory up to about 1.5GB if it was available, so we are puzzled why smaller memory amounts did not impact measured performance.

We are looking for more sophisticated methods to test the impact of total memory on Doom 3 performance. For now, the best we can say is that 512MB or higher seems to be effective. If you have 256MB, upgrade to 512MB. We can also say from a purely subjective point that a Doom 3 system seems more responsive with at least 1GB of memory. Loading Doom and switching back to the screen is much faster with 1GB than 512MB.

    #11 - I've corrected the quote to the 9800 XT which is what was intended on page 10. The same information was correct in the summary on page 11. Sorry for the confusion. The 9800 PRO is around $200 these days but the 9800 XT is still priced at around $380-$390 for some strange reason.

    [q]a plain, old 1024X768, the 6800 is 75% faster in Doom 3 than either the ATI 9800 PRO or the nVidia 5950, both of which cost about $50-$100 more than the 6800.[/q]
    I doubt that a 9800Pro costs $50-$100 more than a 6800.

    It's ok for the most part... some things are odd though. You measured that D3 uses up to 1.5GB of memory, if available. Why, then, did you put only 1GB in the Performance system? Should've been 2. Also, why, oh why did you not use an uber LCD? Dell 2001FP, or the Viewsonic VP201 if buying from Dell is a nono. Third, the mainstream system should've used value RAM - it costs almost half as much, and really isn't much slower than the fastest omg uber hyper enthusiast XMS turbo alpha street fighter platinum EXTREME stuff*, at all.
    Other than those, I agree with all of the choices, even the 6800 for the value system. I was about to suggest an even lower category, for the $500 guys, until I realized that you really can't fit anything half decent in if you have to include monitors and speakers.



    * In the interest of full disclosure, this was Inspired by the following quote from bash.org:

    * ArSa is not a scsi expert :
    * slurpee was a scsi expert until they came out with 134533109 flavors of it

    All I have to say is *damn*.

    A 6800 in the value system? Yikes! My poor 9800 Pro that'll be arriving whenever ATI gets around to it seems inadequate :-<

    I have never seen a value video card priced at $300.

    PERFORMANCE Doom 3 monior.

    OK it's nto a bad monitor, but I can think of better.

    #2:

    640x480 low quality.

    The categaory you complained about was value, not crap.

    Ggiabyte 6800? NO! The BFG 6800 is the best. Damn complementary copy. Even the internet is doomed these days

    Considering that many Americans usually buy systems ranging from 1400-2000 on Dell, I'd think that's pretty 'mainstream'.

    You've been reading too many "i need a systemzorz for 500 bux plz" threads.

    Please note that the listed hardware was for mainstream Doom 3 and not mainstream in general. A 1000 dollars for a computer that can run a game like D3 at 1280x1240 @ high quality is awesome. Dell would charge you well over 2 Grand if not more. Not only will you be able to play D3 at high settings, but Far Cry, Hl2 (if it ever comes out), and next generation games. I'd say that's great value.
