Opteron 165 or 3800x2? ( 2 Views )

1. The opty is a 1.8 piece and the 3800 is a 2.0, I know both can be turned up, and the opteron is about 30 bucks more than the x2.
   
   Opinions?
   I need to decide ASAP.

2. opty has 1meg cache per core (x2 has 512k/core)
   
   3800 has 10x multiplier (opty has 9x)
   
   depending on your motherboard the multiplier may help get a higher overclock
   the extra cache can help a few programs (very minor speed improvements most often)
   
   make up your own damn mind ;)

   You know, it used to be easier to decide before the price changes. The 165 was cheaper, more cache and overclocked just as well so was a no brainer.
   
   I'd still vote for the 165. It's likely to overclock a little better, and you get the extra cache. It should have a better memory controller as well. Cache doesn't make much difference, but it's not something you can add-on by overclocking.
   
   If you're just going to be running at stock, the X2 would be a better choice.

4. Agreed on the opty, they undergo more strenuous testing than the X2's and therefore have more of a chance to overclock better, but also too the X2's have been getting similar overclocks as of lately cuz the optys current steppings haven't been that great. You call, but i'd still go for the opty. :D

5. I think its a crap shoot
   
   my x2 hit 2.8 w/ 1.45 volts.

6. Opty. No doubt. Got two of them and had a total of three in my hands. No problem reaching 2.6 at 1.5 v dual primne stable. 2 of them reached 2.7 so there ya go. That is OVER a 50% overclock.

7. this type of thread comes up almost everyday...
   Opty 165 btw...

8. Seriously. Dont people read any other threads. People make these 10 times a day asking the exact same question.

   No, I don't read any other threads, I just thought I'd ask the same question for the tenth time today just to piss you off.

10. It just gets annoying to see a flood of 1231231 threads close to eachother asking the same question daily. I have seen in the past, literaly 3 of these threads sitting next to eachother with the same question asked. Just read some older threads people. :P
    
    Maybe this one will stay bumped, so 50 people dont have to make a new one tomorrow....

11. If you are purely interested in overclocking, I'd get the 165. If not, the post way up near the top explains the differences pretty well.
    
    Right now, considering the close price, I'd take the 2x 1MB cache. It might be the edge that keeps the CPU viable a little longer.
    
    Plus the mem controllers do seem strong on the optys. My 165 does about 2560 all day long. An X2 3800+ won't do much better. So again I'd take the cache.
    
    Now if you can reach up to a X2 4400 in price, all bets are off, since you get 1MB either way.

12. i'm a fan of the opty regardless of the fact it is no longer the cheaper chip. I think it's a better chip

13. I have both... They are both very good, the Opteron has more cache and is... well.. more fun.
    
    The Opteron will probably run a little cooler as well, atleast mine does. My X2 is running at 2.7 Ghz, my Opteron is running at 2.8 Ghz. I am almost sure that both can go higher, especially the X2 3800+, I just haven't taken the time yet to see what they both can REALLY do.. I honestly couldn't decide either..

14. You really cant go wrong with either. At stock, the x2. If ocing, theres no way to know which will go higher.

15. Since people keeping asking this question, then there should be a sticky for it as obviously there is a demand for this type of quick answer/info.
    
    Thanks!

16. as far as overclocking is concerned i dont believe opterons are automatically better. Overclocking potential is unrelated to opty / x2 binning. The first criteria for an opteron/x2 4400/4800 is 100% working cache. If a chip has some damaged cache the non-working portion is disabled and it is used as an x2 w/512k. The remaining 100% flawless chips are binned according to clock speed for opteron and highend x2 lines w/1mb cache. as each products quota has been filled (best chips to fasted clock working down the lines) only then do faster chips get bumped down to lower end lines.
    
    Many chips are automatically binned as 512k parts because they have damaged cache. Some of these chips clock higher than average but were quickly binned as a cheaper part because of their cache. This (could) mean your likely to get a better overclocker with x2 512k product over a low end opteron because there are more parts that clock high in this line. This is because it does not have a high end equivalent (with 512k) eating up all the best parts.
    
    Now amd very well may have yields where a very high percentage of processors have fully working cache. If this is the case then most 512k x2's have working cache but half is disabled during manufacturing so as to have enough parts to meet demand. If this is closer to the truth then depending on the % of actually damaged x2s in the line changes the chance of getting a fast part binned on the cheap due to cache.
    
    Whiew hope that makes sence.
    
    I just think its wrong to say optys OC better than x2's. Until we know exactly how amd bins its parts its impossible to know the whole truth

17. People here mentioned that the Opteron has a better memory controller. I was wondering if this better memory controller will allow 4 Crucial 512mb pc3200 single-sided ram installed will o/c faster then the slow 210mhz(won't past memtest86 any higher) i'm getting now with my venice core cpu??
    
    Another thing is with dual core is does the ram get shared by both cores or is it split up between the two? What i mean is if you have 2GB of ram does each core limited to1GB of ram each?

    agreed. Speaking as an owner of an dual opty I'd say get whichever you can find cheaper. I've heard the Opty actually runs a little bit hotter than the X2 3800 because of the larger cache which according to members on this forum does nothing.

    If you're truly tired of questions like these popping up everyday...don't read the forums :)
    
    I'd take either one personally, and the extra cache does have a performance effect on server-like applications, but not as much on typical home applications.
