Opteron or Athlon 64 - Page 2

post #11 of 26
sorry to burst everybodies bubbles here ppl. every1 get on google and google the optys out. just so that u guys know optys upto 160 are all single cores excluding the 160. optys after that upto the latest which is 180 are dual cores. the reason the first generation optys which were single core did so well were because many of them especially the 146 were based on the San Diego core. while the newer dual core optys are denmark cores. so the earlier generation opty dont compare to the A64.

A64 are dual core processors. just like the Optys 160 to 180. difference is the A64 are made of normal binning material and is sort of ur average dual core AMD processor while the Optys are made of better binning material and therefore are of better quality and made to more strict standards required by the workstation and server industry.

the single optys have been know to oc very very well. however there is very little evidence of good oc on the denmark optys. but then there is not much evidence about the A64 doing very well in terms of oc either.

its all ur decision but consider that AMD is trying to stop the enthusiast and ocer from purchasing the Optys. Optys 1xx are single processor servers, 2xx are dual processor and 8xx upto 8 processors.

edit : anyways i am not suggesting either one coz i m undecided myself on what to get

credit due to the duke, and the rest of guys who educated me.

I would personaly go with the Athlon. I'm getting real sick of this Opteron craze and will probably never get one. I had read somewhere that on the duel core opty's the memory controller is not as good as the X2's. So IMHO get the Athlon.

The Athlon 44 specs link
http://encyclopedia.thefreedictionar...icroprocessors
The Opty link
http://encyclopedia.thefreedictionar...icroprocessors

Note... not all Athlon 64s have 1024x2 cache, some have 512x2
All the X2 Denmark have 2x1024 cache!

BTW... the Denmark ALSO uses the "E6" memory controler
The single core Venius however still use the E4.

Duke, (Or anyone else.) you seem to know a bit about it, so here goes:

Ok, between the Athlon X2's and the DC Opterons (S939), which will do better under extreme conditions, like high class water or phase, with a high FSB, namley ~300mHz?

Without arguing with you, I'll simply ask you to find a single piece of evidence backing either of those claims. Also, how can you explain the fact that a San Diego based Opteron and a A64 clocked to the exact same speeds will not have the same performance? The A64 will perform slightly faster.

Tough question... most of both seem to hit at least 2600ish... luck of the draw on the core stepping ... but the Optys usually seem to need a bit less vcore in some cases.
With an X2 Athlon... the 512x2 cache ver would produce less heat so that is a consideration but the advantage of the 1024 cache in either is a far more productive unit which boosts performance to each core about equal to having 200MHz more.

Good point... I would like to see that info in print to!
It is believed that the Optys are cut from the premium material... there are in fact better parts of the core and will have an effect on the overall quality. The purpose of the Opty is to produce an alterantive to the previous 940 and heat in a server is an issue which brings the "premium" core material into light!

Opteron Pros:
Large cache
Low price for good performance
VERY HIGH OC'ING POTENTIAL, higher than FX60 (even when OC'ed)
lower temps than the Athlon 64
Better Binded silicon for better stress handling
Versatile Processor
Cons:
This is the Opteron, no such thing exists

Or.....the Opterons have relaxed memory controller settings and/or cache timings, slightly trading performance for reliability. This would also explain the slightly slower performance at equal clock speeds.

if you can get your hands on a CABNE your a lucky man, they are the best stepping in the single core opty's but they are rare, as they were one of the first ones to be released.

I've heard reports of AMD only letting people with legitimate reasons (small business's that need servers) buy the opty's, it seems you must fill out forms to get access to them, so it seems the only places you will get them is through EBAY or some other auction site.. and possibly shops stocking old stock... or something, this could be all wrong though,

I think the real reason why AMD is doing that has already been mentioned, Enthusiasts and Overclockers find these chips soo damn good...

unsure how the Opty 160-180's overclock though... might be something worth looking into...
