Opteron and X2 explained.

Is there a reference page that shows all the stock voltages, FSB, and multiplier of the chips on the market today. Just one big spreadsheet rather than having to google each result.
 
Nice thread. I myself am deciding between a 4400+ X2 and opty 170.

I need to decide if I am going to OC or not, because if I do, it's the opty, if I don't it's the X2. Then there is which board to choose with it. I like the ASUS A8N32-Sli, but have seen people w/ problems with that and the opteron 170. Any thoughts?

And yes I know I am posting alot about this, as I am trying to finalize my build and order the parts.

I dont know much about asus boards since i havent used one since my athlon xp.

I have an ASRock (asus' cheap brand) board with an Opty165 on it. I can get it to about 2566MHz stable, higher than that, and I get random lockups in Windows. Your sig says yours is running at 2889.... what core voltage are you pumping it with? I can only hit 1.4v without a volt mod on this board.

Each chip is different so my what im running wont matter much for you. But since you must know its 1.425. My motherboard is what is limiting my chip as I cant go any higher on the FSB. 🙁 If i were you I would get a new board for that opty. It just doesnt belong in a ASRock board 😉

What about HT's on each chip X2 vs Opteron ? I think the Opteron has 3 HT's and the X2's only 1 HT..

There's a new mobo coming out the Asus K8N-LR http://www.zipzoomfly.com/jsp/ProductDetail.jsp?ProductCode=247067

I think this mobo w/ pci-e and pci-x will require a Opteron w/ 3 HT's to use both pci-e & pci-x at the same time.

Its true that the opterons have 3 HT's and the x2s only have one. The way I understood it though was that it shouldnt have any real impact on performance. I dont know about using pci-e and pci-x at the same time. Maybe on that board as it may provide a seperate link to one of the non coherent HTs.
 
here i did a comparison on new egg, the opteron 165 has more L2 cache than the 3800+ X2

to get and X2 with the same amount of cache you need to go to the 4400+ and its over 130 dollars more

could the opteron be a better buy even if you don't plan on over clocking

It would depend on what you will be doing and if you want the better HSF. The additional cache is on average worth about 100 mhz clock speed. THat is on average though. A few programs make very good use of it while others see no increase in speed at all.

I like the Opty. It is tested to higher standard and according to AMD is made from better materials.
 
now that i look at the clock speeds X2 3800+ being 2.0 Ghz and the opt. 165 at 1.8 Ghz (the additional cache for each core i suppose might at rought 200Mhz?)

so there are almost the same, with eh opt. having a better HSF, i suppose you just have to wonder whether the HSF is worth the 30 bucks
 
and what about the hyper transport?

opterons look like they do 1000Mhz while the X2's do 2000Mhz, is there anyway that can be utilized? wouldn't the motherboard have a cap or something

sometimes you can find the opty cheaper than the x2 I payed $260 for my 165 back in january.

Stock speeds the 165 will be slightly slower than a 3800.

your paying $30 for a better hsf, better quality chip, the name and only a 9x multiplier instead of 10.
