First review of Opteron s939

Petr · 09-04-2005, 10:48 PM

Hi!
I published the first review of a new Opteron socket 939. This CPU uses San Diego core SH8-E4 and features 1 MB of L2 cache. It is available at speeds 144 (1.8 GHz) to 154 (2.8 GHz). Price should be comparable to if not less than A64.

The link is HERE . Just it isn't in english but pictures speaks for themselves.

This one particular sample of Opteron 144 OCed very well - it allowed for a 1 GHz speed gain what is more than 55% of it's nominal clock.

CPU-Z thinks it is s940 but it is s939. Vcore had to be raised to 1.50V to get this stable. Cooler used was a BOX for FXs and X2s (the one with copper base and four heatpipes).

do these work in normal motherboards

that is a massive overclock....is that voltage correct....are we takling SS here or stable speeds

Petr · 09-04-2005, 11:20 PM

Yes, they do work on normal motherboards as Hammer Unknown Model. Some motherboards have a direct support for them - for example Abit AN8, ASUS A8N or DFI. I think more are to come.

At this speed of 2816 MHz, at 1.4V, Prime95 fails immediately. At 1.45V it fails after six munutes. So I think at 1.5V, it could be stable. I used a cooler that is not a top performer and the temperature with this kind of OC at heavy load of BurnK7 was 63 degrees. With a better cooler, it could probably do better.

looks interesting
I wonder why they released a 939 opteron?

Because it doesn't need registered memory, therefore the platform is much cheaper.

Seems to be more overclockable than the Venice's ???

Not sure but Opteron is manufactured on better silicon because it is a server product and has higher demands on stability. It also usually has higher TCaseMax specification than Athlons.

if they all perform like this one......i'd love one

are all Opteron 144 CPUs S939 or are they shipping S940 as well

They are also shipping for s940. s939 versions were launched only a month ago so currently they are hard to get.

ditto
if the 144's are like the current 940 144 opteron maybe we can get them for about $300 or similar to a venice 3200 price

xs64 · 09-05-2005, 02:47 AM

What does the different between Opteron and Sandy ? I mean all in socket 939 , can i get more performance with the Opteron S939 ?

Petr · 09-05-2005, 02:57 AM

Opteron 144 can be bought for a price comparable to A64 3000+. According to AMD's pricelist, it's even cheaper than that!

There is no difference between Opteron and San Diego A64. Both use the same core and therefore have the same performance.

linhvndiy · 09-05-2005, 07:07 AM

Please do more test. How it perform in server task?Thanks.

Mysterfix · 09-05-2005, 07:39 AM

Very good news indeed, can't waite for these to hit the shelves.

largon · 09-05-2005, 07:41 AM

Aren't Opterons fully multi-locked?

gundamit · 09-05-2005, 08:01 AM

So does 939 Opteron 144 = A64 3000+ with 1MB or Sandy at 1.8Ghz and 9x multi? Any way you slice it, it gives us another choice. I'd warm up to it a bit more if prices hit the sub $200USD mark.

largon · 09-05-2005, 08:30 AM

gundamit,
A screenie in that review shows "SH8-E4". It's a San Diego w/ x9.

nn_step · 09-05-2005, 08:55 AM

can't wait for dual core 939 Opterons

The s940 1xx chips on .09 are impossible to find. I don't think they will ever be made. Actually AMD doesn't show them as available at all, only .13 micron. Also, I noticed the case temperature is related to warranty in a way, the one year warranty chips for s940 can vary between 49-67c, but the three year chips are always 67c. On s939, the 150 has the highest at 71c for both boxed retail and oem. !!

Apparently, the highest you can get on s939 is the 152 (2.6ghz).

WOW, there are s939 opterons there with 2mb L2 cache!

Is that true?

That opterons looks promising... if they are down-unlocked with 1mb... so nice

nn_step · 09-05-2005, 12:41 PM

or the fact that they have 3 hypertransport links...

They are made and shipping in Sun servers AFAIK, IBM will be shipping soon as well. The x75 series are shipping like nuts and with good reason.... they take the performance of the socket 940 to xtreme levels.... though I do have to add that at the 8way status the PPC servers are still kicking butt.... I think that will be remedied as companies like Serverworks and Nvidia make more serious chipsets for these Opty's as the potential is definitely there..
