QX6850 vs i3 2100

Hey guys how is the QX6850 running at stock speed vs the i3 2100 stock speed in gaming? Which one is better? Games like battlefield 3, Skyrim, witcher 2, counterstrike Global offensive, Dragon age 1/2, Mass effects 1/2/3.

GPU is gonna be 7770/7850 Radeon or Kepler GTX660 @ similar speed.

I am on a socket 775 platform now with a Pentium D 805. Motherboard support qx6850.

Pentium D 805 has TDP of 95w. QX6850 has 130w. Does it mean QX6850 use more power? It is hard to measure TDP across diff CPUs since Intel measure it differently. Pentium D is 2x Prescott 90nm glue together.

    for bf3 multiplayer, or any multiplayer, a 4 core cpu would be better than a 2 core cpu.

    imo a core i3 would be a good upgrade from a pentium d, core i5 would be even better. afaik the qx 6850 should be costly enough to warrant a full platform upgrade to a sandy bridge or ivy bridge. i looked at amazon and it says $970-$1400. even a refurb one is $400.

  2. I found that my Q9550 was at it limits (constant 95%+) on bf3 64 player maps @2048x1152, or very concentrated maps (noshar TDM). my 3570K@4.3 runs at 40-50%. my Q9550 did stutter. The Q9550 cam up with 35ish gflops on ibt, my 3570K 105gflops, so i'd suggest that 50gflop plus would be ok. So the question is how may gflops on a QX6850?

    The qx6850 and q9550 should be rather close to each other and almost equal when clocks are normalized. I know that SB dual core like the i3 only scores roughly 20-25gflop while the quad cores versions it is easily double depending on the sample however there is a lot more to it than just raw floating point performance that makes a great performing cpu.

    absolutley true, however my bf3 perf seemed to want 40gflops, and now its got it its fine, at 38gflops available i had to turn stuff off to be happy, so in this case, and possibly only this case, it works.

    Clock for clock the qx6850 and the q9550 will be similar (maybe q9550 5% faster) but I was at 2.83 and didn't OC. The 3.0 Ghz qx6850 should be ok, especially if a small OC is applied.

    the hierarchy chart, shows it is 2 tier slower so which one is faster? I am not looking for games b4 year 2009 tho. Do we have bench on i3 2100 vs core 2 quad on games?

    for some lucky reason, I was able to grab an used qx6850 @ $100 only :sol: , from my friend in my work area. it is a clear choice or i3 is better? it cost about the same by selling my old platform + going for i3 platform.

    now for PSU thing, is qx6850 gonna use more power @ stock clock vs pentium D 805 stock VID (FSB OCed to 3.33GHz) I cant seem to find qx6850 power usage vs pentium D 805.

    my system spec
    9800GT
    4GB RAM
    2x HDDs
    3x80mm fans
    450w true power PSU
  6. true quad would be better, so of those two choices, qx6850
  7. looks like you have the cpu already. at that price though, it (qx6850) seems like the better value because you don't have to change platforms right now. hopefully the cpu is in good condition and will help you hold out till haswell. :)
  8. I would not bother upgrading unless you upgrade to a CPU that is truly worth upgrading to like the i5-2500k or i5-3570k

    While the i3-2100 is an upgrade of some sort, the improvement is not enough to justify the expense and to it is just a waste of money.

    I have a Q9450, but I'm waiting for Haswell to come out before upgrading. Perhaps I'll even wait until Broadwell is released.

    I havent buy it yet but gonna do so today. I hope this CPU in good shape & actually outperform 2100 in the newer games when I change my GPU later.

    I am planing to hold out until Skylake/Skymont.
