AMD X2 vs. Opteron

tomokatsu · 14-December-05, 09:31 PM

Hey, I am getting a new computer soon, and I was debating which cpu to get: an AMD X2 4400+ or an AMD Opteron 175 Dual-Core. They are both running at 2.2 GHz, with 1 MB of cache (per core) both fit a socket 939 board. They are approximately the same price (~$20 difference).

Any other suggestion would also be appreciated. I am looking to create a new rig that can withstand my heavy multitasking, and multimedia design (grahpical, web, animation, and 3D). I already have 2GB of RAM and just need any suggestions for the CPU. (If it will help, I was considering an Asus A8N SLI Premium board, but still open to suggestions)

Thanks, Tomokatsu

They are the exact same cpu pretty much, the opteron might overclock better though..

tomokatsu · 15-December-05, 02:42 PM

yeah, i figured that, should i just go with the cheaper one? (opteron)

Demon Made · 15-December-05, 03:33 PM

the opteron is optimized to run buisness/server apps, i dont know if there will be a noticable performance difference on it with games but they were designed for different applications.

Jager · 15-December-05, 05:21 PM

an opty 146 overclocks well under certain steppings the cabyne and cabne are the two ones that break 3.0 ghz. in testing they do as well as the x2 when you are using a single core on the x2 however when you step up to dual core on the x2 it does better in benching. gaming they are bout equal.

i am assuming you are referring to the opterons in socket 939 though.

Not true. The Opteron is simply made of more choice silicon to take the stresses of server-based work, and also usually has more cache. Other than that, it's an Athlon 64.

tomokatsu · 16-December-05, 05:12 PM

thanks... I am looking at processors with the same cache size and speed (GHz)... both are socket 939....
I am planning to do mild-heavy graphic design, but I doubt that really matters... (some gaming tho)

right now, unless someone convinces me otherwise, the opteron is looking pretty good.... anc someone please explain the difference with the "cabne and cabyne" stuff...

thanks for the comments

I'd have to cast my vote for the Opteron also.

Yea this is true. In this case however they have the same ammount of cache per core. I would go with the Opteron because like Ator said the Opterons are "binned higher" Meaning that a chip can run 2.6ghz but just to be safe AMD clocks it to 2.2 and sells it at 2.2 for super stability in an server enviroment.

THRASHER2 · 16-December-05, 07:10 PM

Opteron for the WIN!

tomokatsu · 17-December-05, 08:47 PM

Thanks for the info guys...

BigAkita · 17-December-05, 09:16 PM

I was going to offer to bench the Opty against the Dual Core, but then realized it isn't a fair fight. The Opty 939's are so far underclocked that bringing them up to speed would make the 4400 I have look like a Duron.

CABNE, CABYE, CABGE are shortened "stepping codes". They refer to the date of manufacture, stuff like that. Processors of certain steppings have been shown to overclock better than others, despite being the same make/model/speed.

Right now, the CABYE and CABNE steppings for the 146 Opterons are the hot overclockers on the market, if you can find a retailer that will guarantee a CABYE/CABNE stepping...

Another vote for the Opteron.

cpjlam · 27-December-05, 05:27 PM

Another benefit to using the opeteron is the definite availability of all three HT lanes (more CPU to I/O hub bandwidth) versus the [typically] reduced count on the Athlon 64s. I haven't actually had the chance to double-check, but does anybody know whether or not the Athlon 64 x2 chips utilize one HT lane or if they have all three lanes enabled?

BigAkita · 02-January-06, 01:46 AM

There is no comparison. I reinstalled my X2 in my testbench and it cannot even hold a candle to the Opty. It isn't as much a tribute to the Opty, but proof that clock speed is more important. The benches I pull with an overclocked X2 are not even in the same league as what I am pulling with the same board with the same RAM on an Opty. If you need further proof, buy both of them yourself and bench them.

Chrome_Rust · 04-January-06, 01:23 AM

Also dosent the opty have locked higher multi's vs the X2 unlocked nature?

X2's are locked also...

hink · 04-January-06, 03:36 AM

Aren't the only cpu's with the multiplier unlocked both up and down the FX series?

i voted for the opteron being a fav. among gamers .... but being a graphic designer ....
what apps will you be using ????
(some apps are more efficient on gaming rigs than on production rigs)
am no expert, but i do have seen MAYA run better on the AMD X2, and for some reazon lightwave and 3dsmax perform faster with the opteron
