A8 3870k vs PIIX4 955 BE

I was wondering what the processing power of each of the two cpus compares, no gpu, just the cpu. The A8 3870k, is a cheap solution with a 6670 and give option to upgrade gpu later, but im not sure how much better a phenom ii x4 955 be compares to just the cpu portion of the A8? thats at stock settings no OC, and if any oc at all would be small.

    I would say they will be close in performance to each other. Below is a link to benchmarks of the A8-3850 vs the PIIX4 955. The A8-3870 is not an option, but the difference is only 100MHz. Also, socket FM1 is dead. If you want to upgrade your Llano APU, then you need to buy a new motherboard as well. Trinity uses socket FM2.

    I would get the Phenom II X4 965 for $110. If you buy a socket AM3+ motherboard, then you have the option to upgrade to PileDriver later on.

  2. I know that fm1 is dead but not buying a super expensive motherboard either, and i got a cpu cooler and the 955 is $75 oem from tigerdirect. it'd be 175$ for a a8 3870k and 6670, and 240 for a phenom and 7770. the am3+ gives option for piledriver, but the a8 gives similar performace graphics wise and cpu wise to the more expensive am3+, and has room for upgraded gpu.

    Spend more off the bat on the am3+? or save and upgrade later on the gpu, since u heard a a8 and 6670 preform similar to a radeon hd 6770, which i use and play bf3 at high 1080p at 30-40 fps.
  3. It all depends on the use you have in mind for the processor. Are you a gamer? The 955 is a tier above the 3870 for gaming capabilities.

  4. It'd be use for daily use and play bf3 and other games. so yes gaming

    BF3 takes a good CPU and a good GPU, unless you are satisfied with lower settings. If you want to play at high settings, take jaguarskx's advice and opt for the 965. O/C'd, it can keep up with most any graphics card.
    I'm going to buy another 965, just because they're almost gone, and the PhII X4 BE's represent the best of AMD's previous generation of CPUs.
  6. I dont beleive in the hierarchy thing, im not sure how an fx 4170 beats a 1100t six core, and how some of the best amd cpus barely beat core 2 quads and first gen i3, i understand intel is better but my opinion is that list is BS.

    You're entitled to your opinion. Afterall, I'm sure Tom's hasn't spent anywhere near the man hours testing the processor combinations that you have.
  8. the 965 be is $15 more than the 955 be oem on tigerdirect and kinda on a budget so id take the loss. and my friend who is looking at the processors, was willing to play low to medium settings on bf3 as from what i seen a ps3 plays bf3 at low/med as a pc would. He plays a lot of ps3 so he isnt to concerned about graphics settings.

    Also know bf3 is cpu intense as it uses alot of my 6 core, and easily can be played by a 955/965, and prob any a8 and better a6 apus. im not to concerned about cpu causing issues in playing, and obviously not in fps in quality.

    Personally i dont think a x4 or a8 would bottleneck a 7770 or 6670 or the other way around.
  9. If you are on a budget then go for the A8-3870k. It is still good for games, but not as good as the X4 965. The APU should be fast enough for a few years to play games since most games are limited by the graphic card instead of the CPU.

    Just be aware that installing anything faster than a Radeon HD 6670 will deactivate "hybrid crossfire" or "dual crossfire" or whatever AMD calls it now.

    I understand that testing each cpu and putting a list together takes time and helps other i just dont understand how a bulldozer quad core ranks higher than the best phenom six core. i didnt read much on the list and how it was done, i can maybe understand if its performance to price but if its pure gaming performance then apparently amd has to rethink there whole cpu line.
  11. i know i was saying the 7770 that would be put with the x4, and it'd be a 955 for the price it saves.

    and questions rlly is cheaper solution a8 and 6670, save around 70$ and upgrade later? or spend the little extra now and go with the better cpu and gpu?
  12. the reason why in general 6 core processors don't score as high is because of the fact that less than 1% of games even go past 4 cores.
  13. ^^^
    Someday, maybe. But any CPU with more than 4 cores is wasted on gaming at this time. Good for other stuff, tho.
  14. nope, bf3 very popular and played by many multiplayer will use quite alot of my 6 core, and figured out that the phenom x4/7770 would be a better for the little extra.
  15. No one is saying a PhIIX4 will bottle neck those cards.
  16. i didnt think so and i guess no one rlly did i assumed since it was mentioned to get a 965 oc when i kept saying 955. but i think i made my decision since the apu build wouldnt rlly be saving much money for the performance.
  17. 955... 965... they're the same processor. The ones marketed as 965s just passed with higher grades is all. You can probably get a couple MHZ more freq out of the 965s if you O/C is the only difference. Folks that buy Black Editions don't keep them at stock speeds anyway.
