Fallout 3 Analysis

Try as we might, Fallout 3 performance is very limited by LOD optimizations. We tweaked the .ini files as much as we could to make performance GPU limited, but we just shifted maximum performance down across the board. This is similar to how Oblivion behaved with single card solutions, but this time even multiGPU solutions are affected. It's not a failing of the game, as we do recommend turning on vsync and (if possible) triple buffering when gaming; it just makes testing "goodness" of a graphics card more difficult.

None of our single GPU options hits the frame limit, which does help. Everything runs fine at 1680x1050 and all the multiGPU options are essentially equivalent in performance at this resolution. Moving up to 1920x1200, we see a similar situation, but the 9800 GX2 starts to fall off a bit. Luckily 2560x1600 offers us a better look at what cards stand up when really pushed by Bethesda's modified Gamebryo engine.

Graphics memory becomes a factor at high resolution, and the multiGPU options with only 512MB per card tank in performance. Both 9800 series options and the 4870 512MB / 4850 CrossFire options drop off sharply in performance. This leaves the 4870 X2 and 4850 X2 solutions in competition with the latest and greatest from NVIDIA at the top of the heap. It's clear that the highest end NVIDIA parts have more headroom still, but unfortunately this test won't reveal everything they can do. The 4850 X2 2GB and GTX 260 SLI do drop a little off the frame limit, but the drop isn't hugely consequential.

Scaling data is horrible here because of the limited framerate. Basically, rather than looking at how much better two cards perform, the metric is how slow the single card is. Thus the best scaling we see in this game comes from the 9800 GTX+ and the 4850 until we hit 2560x1600. When we start to finally get a glimpse of real scaling in Fallout 3, the GT200 based NVIDIA cards definitely take the cake.

In terms of value, the frame limit also hurts multiGPU solutions because despite the increased cost, you can only squeeze so much performance out of the hardware. Once again, we note though that the 4850 X2 has very good value and good performance especially compared to the single GTX 280 and 285.

    1.Let me help you out. More people have 1280x1024 monitors, and any who do have flat panels, are most likely stuck at 1680x1050 because the 1920x monitors command a premium.
    So MOST GAMERS are far below 2650, and 1920, and even 1650, and some can't run 1280x1024.
    A common game rez is 1024x768, 800x600 is also used currently on all the high end games - both especially with gamers with brand name store bought systems - we all know the big names ( not the multiple thousand dollar gaming brands - that's one of 50 gamers!). When you're stuck in a lab with $2,000 monitors and then travel to checking out the cebit babes, staying in touch with the average gamer is difficult, to say the least.
    2. Even though the 260 passes 20 of 21 tests, and the 4850 passes LESS, Derek the red just HAS to state that the Sapphire passed every test they threw at it. Now the upper number doesn't jibe with that - the one showing the 4850 worked in LESS situations than the GTX260 -
    ( obviously more than one 4850 brand was in play - NEVER THE LESS - that is the type of CONSTANT red slant that is all over EVERY SINGLE PAGE.)

    I found an oddity. This articles posted power consumption doesn't correspond to other articles findings; yes I know I can't cross reference data across articles. In this article:
    The 9800GTX+ uses less energy than the HD4850 and in this multi-GPU article it's the other way around. I know I can't compare total system power findings but I'd think that the cards would at least be in the same order.
    Can someone PLEASE clear this up for me? I'm very confused as to which card is more power efficient as the findings have varied so heavily across different articles.
    It would probably be a good idea to list the power consumption of only the GPU, instead of the whole system. Doing that would remove variables, which is of course, a goal of any scientific experiment.

    I just wanted to say, this is a great article. I'm glad you guys finally wrote an article comparing pretty much every card out there that people will consider buying, you could have included some lower end cards and resolutions. But hey, it takes a lot of time to do that many tests accurately; I appreciate all that you did do. It really was a well written and interesting article to read; good job anandtech.
    P.S. Any news on when new GPU's will be coming from Nvidia/AMD. I've noticed a LOT of price drops and mail in rebates on GPU's recently.

    "In general, more than one GPU isn't that necessary for 1920x1200"

    Depending on the definition of "that":) I disagree, gameplay is so much smoother with two cards on a 24" monitor. I tried playing with one 285 versus two, and while I don't have any real numbers, the differences is very noticeable. Crysis never dips below 40fps. This is my first real SLI since Voodoo II and I'm very glad I did it. You can always buy one card and decide if you want the second one later. I paid under $700 for two 285s and also got a copy of World at War and FarCry2 with two cards (a fluke maybe), that's almost $100 worth of games:)

    Im currently using an ATI 4850 512MB at 1920x1080 on an x58 chipset system.

    I just ordered another 4850 for crossifre usage due to this article.

    Thanks for the tip. Keep up the good work.

    I know it's 2 years old, but it is still a relatively taxing game for it's age and is still relevant with the Tales of Valor expansion coming out... so could you PLEASE add Company of Heroes back into your reviews? I would just ask for Dawn of War 2 benchmarks, but it's the same engine and they didn't include a nice performance test. As it stands there are no RTS's in your hardware reviews. I'd just like to see a broader spectrum of games represented. Reply

    I second the motion to include CoH. Reply

    i gotta commend u on ur graphs, very clean and very easy to understand unlike some other sites that have confounding line graphs. i especially love how i can choose between different resolutions to see the diff instantly. Kudos to u guys.:) Reply

    I upgraded my gpu awhile back and got a MSI 4870 1 gig (ATI) card to replace my old MSI 7600gt 256 mb (Nvidia). However, although I can get better quality graphics with the ATI card, the Nvidia card is actually faster when playing Vanguard soh.... The game loads slower and takes more time shifting graphics (graphic lag), but the graphics look better and I can turn up settings a little higher. Any ideas on what's going on?

    Any time you increase graphics settings on a game you increase the amount of information that needs to be off loaded to and from HDD, CPU, RAM, GPU so this is likely you reason for slower load times.

    But that card is in not actually "faster" than the 4870, in actuality that card is probably 2-3x better at rendering then the 7600 across all games.
