Opteron X2 VS Athlon X2

[Ti22]

Hey guys,

I am deciding whether to buy Opteron x2 or Athlon x2 and I've been reading up everything I can find on them unfortunately i can't find a nice review comparing the cpus i am intersted in.

anyways I have seen 1 review over at techreport.com and the Athlon X2 seems to be faster than the Opteron X2 in the review they compared Athlon X2 4200+ with Opteron 175 and the Athlon X2 beats it in almost every test. and also has significantly lower power consumption.

Are you guys forgetting that the Athlon X2 has 256 L1 Cache thats 128k per core. sure it has 512k L2 per core but L1 cache is much faster than L2 cache rite?

the Opterons have only 64k L1 per core even though it has 1 Meg L2 per core it still can't beat the Athlon X2

Can you guys give me your 2 cent on this?

Which should I buy I can't decide, btw I will be putting it in a shuttle SN25P System.

Thx
Ti22

So much ignornace here let's start at top.

1. Opteron used there, a socket 940 opteron, required ECC/REG mem which adds an additional wait state in memory which accounts for slower performance. new socket 939 Opterons are the same as X2's in performance because they can use regualar ram.

2. No dual core has 256 or 128 KB of lVl2 cache.

There are two flavors

a) with 1024KB - 512KB per core
3800+
4200+
4600+

b) with 2048KB - 1024 per core

165
170
175
4400+
4800+

3. All A64's have same amount of LVL 1. 64KB + 64KB per core. All Dual cores have same amount. 256KB.

4. You want the 165 or 170 939 opteron. Best price/performance.

Hey thx for the reply,

I guess I will be getting the Opty 170 then.

sorry for being ignorant. but sometimes u have to be ignorant to get people to tell u stuff

When going for an Opteron be careful to get s939.

 

[Shimmishim]

dualcore you can't make a mistake since there are no socket 940 opty 165,170,175.

 

[Skott]

Well, to be fair AMD & Intel dont make things easy with all these different types of chips to choose from. Variety is good but it can also be confusing. I'm just glad the people here are generally nice about explaining things. The gods know I can be slow about understanding stuff sometimes. LOL

That's OK Ti22 - not meant as an insult.. Least you reading a good sites techreport/anandtech rules. Oh and I forgot another 939 opteron the 180 http://www.monarchcomputer.com/Merchant...PROD&Product_Code=120346&AFFIL=pg&NR=1

so is there any real difference between that and a 4800+?

That's right - reviewrs did no know at the time they rushed out thier dual core opteron reviews AMD had 1xx slated or 939 and used 275 (a 940 chip) by itself in 940 boards to "immitate" a 175 in performance. That has caused much confusion to buyers who all saw a "175 opteron" running in 940 boards.

not except the name

both have a toledo core, although i believe the opteron DC cores be named Denmark instead

Just name.. And I suspect opteron is a little more tolerant of temps since they are supposed to be for professional/server rooms and people. Can't have the chips get a little hot and dusty and start erroring out ...bad news for AMD PR. Cherry picked is my opinion from results we see. Like 144's up to 3Ghz ..like 165's up to 2.9 Ghz and stuff.

Hey guys,

I decided to get the Opty 170 as said above however I have 1 question about overclocking.
and I was just wondering what kind of overclocking i would be able to get at stock vcore. and is it smart to overclock a shuttle? these things are pretty tiny.

The problem with optys is that most of them do not oc very well. There are 3 revisions. 1. OC's really well but is very rare 2. Sh!ttiest ocer ever 3. In between. Its total luck whether yours wil oc and its very likely that you will get a 2, maybe a 3, but almost impossible to get a 1. They are extremely rare and haven't been seen that much. Not a good buy in my opinion simply because of the gamble with the revisions. A few rares ones oc very well, many more oc ok, and the majority hardly oc at all. Sorry.

 

[harobikes333]

Where did you get that info? that they OC most of them anyway not very good

WTF are you talking about? Opterons are made from AMD's finest silicon. They'll OC the best.

Unless by bad OCs you mean 2.6, in which case you ought to STFU, 'cause thats damn good.

I went the Opteron way also, me thinks Zebo knows more than the average guy. His threads are normally very good.

Can you link your information? For what I see, you have a Pentium system. What experience you have with A64 ?

I say you're geting a 4800+ for $370 instead of $800..

That's a great chip to OC inside a shuttle.. Just leave everything "optimized defaults" Change HTT to 240, LDT 4, and mem to 166 or 333 depending on bios. Leaves memeory running @ 200Mhz and puts chip where it should be.

 

[johnnqq]

so the 939 opteron's DON'T need ecc ram? so they are basically an athlon 64 (obviously not...but you know what i mean) and don't need anythign extra?

I hav'nt seen one that can't make 4800+ (2400Mhz) on default Vcore.. course I only hang at three forums with combined 200,000 users Anandtech, techreport and xtreme. Maybe @toms or other clueless n00bs they can't do it? And the single core opterons are even better.

 

[harobikes333]

from what I've read, No

You like fireworks? My boys get a little Crazy with them at the house..
