Why is my 3DMark05 Score so low with a 4870??

Hey I just recently bought a Sapphire Radeon 4870 and I expected a HUGE increase in performance. However, I barely see any... I used to get 6000 on 3DMark05 with my 7600GT, but now with my 4870 I'm only getting 9000 3DMarks? What's up with this? I was expecting like 30,000 3DMarks with this baby.

Is my CPU holding it back? I know my CPU is ancient, but I thought CPU didn't have much to do with graphics processing. Currently running on:

Windows XP Professional
ATI Catalyst 8.12
AMD Opteron 165 @1.8 Ghz Socket 939
2GB DDR-400 Corsair
Sapphire Radeon 4870 @ Stock (750/900)

  1. 3dmark is surprisingly CPU dependent. The real question is whether you are seeing a big jump in game performance.
  2. i'm just afraid that i got a defective card... do i have to be worried about that?
  3. You CPU is a major bottleneck, and did you use driver cleaner or similar to get rid of all the nvidia drivers?

    Why would you use 05, use 06 or vantage.
  4. in terms of game performance, i get average 100 fps now in left 4 dead 1440x900, low settings. i used to get average 60 fps with my 7600gt, but i still expected a MUCH greater performance increase.
  5. i'm currently downloading 06, i only had 05 from before because the 7600 couldn't handle 06.
  6. Sounds like your card is fine but you need a faster CPU and faster ram. DDR 400 is sloooooooowwwww.
  7. hmm interesting, i'll get around to that.. i just picked this card up first because it was on sale for $140
  8. Well your gonna need new everything except a graphics card. Probably even a power supply and a motherboard.

    Maybe you could get a new Phenom 2 when they come out.
  9. Well I bought a new 700W PSU to power this guy, so I think that's good enough. How would I know if the card is getting enough power from the PSU? I plugged both 6-pin connectors into it, but I'm not really sure if they're both working. Would the card not work if both connectors weren't in correctly or would the card just not be as powerful?
  10. They 4870 does require both connectors to be plugged it. Even a lower quality PSU should power that card, as the rest of your computer sees lower power consumption. You should really consider overclocking your CPU, at minimum, and replacing the CPU motherboard and RAM at best.
  11. so the fact that it does power up means it's getting enough power right?
  12. yes its your cpu, and for gods sake get that detail cranked up in left 4 dead, u got a good card use it
  13. @EraserXIV: The `problem` is your CPU, it cannot feed the graphics card with enough data for it to run at full speed.
    Your PSU is fine, if it were not so, at the worst your system would not boot, at least, it would be unstable with random crashes/lockups/uncommanded reboots.
    All is not lost, though, graphic cards do AA/AF on chip, so you can turn both up without sacrificing frames (as Rangers said).
    AS for MB/CPU/RAM upgrades...Why not check out our other friendly and helpful forums?;)

    Exactly. To test the bottleneck, try to go to 8xAA and 16xAF and see what the difference is in FPS from 0xAA and 0xAF. It shouldn't be too much different.
  15. yeah i tested it out. i put it in my dad's system which has a E6600 and 4GB DDR2-6400 and the 3dmark score almost doubled.
  16. Man, I would say at least 90% of people that have "low" 3D06 scores are using AMD CPUs or are running what ever CPU they have around 2Ghz. Besides 3D06 being a CPU eating machine, AMD CPUs just don't have the balls to pair up with new GPUs like an Intel CPU does. On top of that the clocks really matter.

    I don't have anything against AMD but right now they are way behind Intel in gaming performance. Hopefully Phenom IIs clocked at 4Ghz will pop up soon and return some decent scores for AMD fans.
  17. your cpu. is amd. is slow.

    end of thread.
  18. Yup there are two things that 3DMark loves: High clockspeeds, and Intel CPU's (AMD CPU's have never performed that great in 3DMark).
  19. hmm...

    Yup there are four things 3DMark loves: High clockspeeds, lots of cores/threads, Intel CPU's, and ATI graphics cards. preferably more than one.

    This is also true ^^.

    E8400@3.6+HD4870=15000 3DMark06. Gotta love it, and that isn't really considered a good system anymore.
  21. lol 1.8 gigh opteron with a 4870... damn!
