AMD Athlon II X2 250 and ATI Raedon HD 4870 Bottleneck?

Hello people. I have an issue. I am trying to play BF3 but I only get 30 FPS on low settings. Is my CPU bottlenecking my GPU?

AMD Athlon II X2 250
Regor 45nm Technology
4.00 GB Dual-Channel DDR3 @ 535MHz (7-7-7-20)
DELL 2007WFP (1680x1050@60Hz)
ATI Radeon HD 4200 (MSI)
ATI Radeon HD 4800 Series (XFX Pine Group)

    my specs are very similar

    4GB RAM @1333
    AMD HD6850 1GB (about 10->15% faster than your 4870)
    Phenom II 955BE
    Corsair Force 3 120GB SSD
    monitor i game on is 1680x1050
    no overclocking

    i run with BF3 graphics on auto - most settings say 'high' and get perfect framerates - never been able to feel it drop

    my cpu sits at around 80% usage on all 4 cores.

    I would guess that your CPU is the bottleneck. Try find a 4 core phenom II cheap if you can.
  3. lower your resolution to 1280x800 and watch the frames fly
  4. It's your processor, your below the recommended requirements on the game. My Phenom II X4 965/Radeon 5770 can handle the game 1080p with medium settings.

    Look at this link, look where the Phenom II x2 is compared to an X4/X6 and newer processors, online multiplayer demands more cores.

    My frames flew right back to where they were xD
  6. thats odd, i just ran through bf3 at 848x480, with my specs and i was getting as high as 45fps. did you make sure you set the gpu to performance in catalyst?

    if lowering the res really did not help, then the cpu would be the culprit
  7. Yea I have everything that I can set in the Catalyst to performance or off. And changing the res doesn't change my FPS at all. I can switch from Low -> Ultra and I only lose 10 frames.
  8. well i see the x4 645 on newegg for $99, on the phenom side they jump from the 925 to the 960t
  9. yea I was looking at that x4 645 for 99$. Would that be a good buy that would last for another 2 years at least?
  10. yeh dude, its a good cpu
  11. 533x2=1066 +2 accounts for random frequency fluctuation
  12. Changing the ddr3 helped a little bit but I am still dropping to 20 frames
  13. the problem is your cpu isnt up to the game... your gonna be stuck in the 10-30 fps window even if you drop everything to low and run at 12/7. overclocking to 4.0 wouldnt even help you much. the game needs a tricore or better.
  14. Think of 1998 pentium iii is the world's TOP CPU
    7 years later in 2005 this cpu is RUBBISH.

    Now the same thing happens again.

    athlon FX-62 introduced in 2005 with price of 1099usd as the world's fastest cpu
    and 7 years later now 2012 it worth less than trash.

    think of the ii x2 250 as about same performance of fx-62
    (both athlon 2.8ghz x 2), using aiix2 250 is the same as using
    once-top-now-rubbish fx62 cpu

    above all my opinion IS:
    ur 4870 = ur DDR3 4GB = GOOD
    a ii x2 250 = fx-62 = USELESS TRASH

    i recommend that u buy a i5 system asap.
