Are you trying to make us laugh ? Have you discussed that topics with 10 year olds ? Sorry if that is a real questions, but I thought that everybody should know nowadays, that Opteron S939 are *identical* to its Athlon64 brethren.

The only thruth your statment includes is, that Opterons are picked exspecially for stability/reliability, so the quality tests are somehow stricter. That results in a better overclockability of most Opterons. So you might say (in an odd way) that the Opteron has a "better" silicon.

But at same speed there are NO performance differences whatsoever !

For S939 parts there is no difference with the coherent links either.

I advise to read some Opteron / Athlon64 articels first. Google is your friend

this was taken from an AMD forum on the AMD official website. i thought it deserved its own thread for those asking wether opteron or Athlon 64 X2 were better... and the answer is still your choice.

if X2's and dual core opterons have the same cache and the same frequency, then they perform exactly the same. however, opteron's are tested more strictly before sent to the market, so they are normally better overclockers.

the opteron's L2 cache is higher compared to some Athlon 64 X2 chips, however the L1 cache is cut in half (64+64kb, not 128+128kb like X2's)

so, there's your difference... it really basically just depends on if you are o/cing or not because the opteron will save you a few dollars and give you better performance after the o/c.

you choose what suits your needs! :)

All good, except i think the preformance price curve no places the x2's in a more favourable position.

And the L1 cache matters squat

im sure L1 cache matters somewhat... btw i was wrong they have the same L1 cache though
explain that first sentence its grammatically... a disaster.
no places the x2's?
actually i checked newegg.com and the opteron at 1.8ghz with a larger cache is $30 USD more than an X2 3800+ at 2.0ghz.

so... ingenius. they make many many chips, slice half the L2 cache off some of them for budget chips, and sort them as to clock speed and sell them as people buy them, locking multipliers and such...
wow thats a good way to sell them. :)

care to tell me were it bottlenecks then? Sure it matters, but hardly anything on modern chips.

If the absence of one letter 'w' made the whole sentence illegable then i rate your english understanding on par with my typing. And this is a typographical error; not a grammatical one. Would you like me to trail your post history for examples of good grammer?:rolleyes:

You are making the same point as me, as i more obviously highlighted in our other discussion on this topic today.

post fabrication, now that would be a good way to waste money.
 
umm... lack of communication if you ask me. lol i wish i would've gone with an opteron 165 :( my proc is still really good though :)

It gave me 3000 points in 3dmark01 so i wouldn't say that it does squat. I had a 4200 at 2.7 and my Opteron at 2.7 and the opteron scored 3000 marks higher. Not a huge jump but every bit counts.

thats the L2 cache difference giving you that score, the 170 has 1mb per core over the 4200's 512kb
 
haha yea thats L2 cache... and 3,000 points in 3dmark01 isnt that much... actually i believe that a 512kb per core increase of L2 cache is less than a 200mhz increase... but it still helps performance. it also depends on the application. either way more cache will help but some apps more some apps less.

200 mhz is better than the extra 512 cache, but the opteron clocks the same if not way better than most X2's so thats why i switched.

yea but if someone wasn't planning on o/cing then athlon 64 X2 would be better (for instance, someone who doesnt know how :), or is not willing to risk anything and wants more stability :) )
also, an athlon 64 X2 4400+ has the same specs as the opteron 175 yet the 4400+ sells for cheaper :)
