AMD's Quad-Core Barcelona: Defending New Territory

AMD's Newest Quad-Core
Before we start talking about benchmarks, here's a short overview of the new models and their pricing in the competitive landscape. AMD is launching both 4/8-way (4S) and 2-way (2S) models of the new quad-core Opterons at speeds ranging from 1.7GHz to 2GHz. To keep things simple, we'll first take a look at the 4S (four socket) market.
AMD uses a different power rating than TDP: "Average CPU Power" or ACP. AMD claims that this power rating is very similar to Intel's TDP: it is the average power draw when the processor runs high utilization workloads. A CPU with a TDP of 95W has an ACP of 75W; one with a TDP of 68W has an ACP of 55W. According to AMD, ACP should be the number we use to compare to Intel's TDP. We'll verify this claim in a later article.
Let's see how the new Opterons compare to Intel's CPUs when it comes to pricing and power:
First of all, it is worth noting that the old Tulsa Xeons remain very expensive and are not even worth considering as they only offer half the performance of Tigerton. The same can be said about the Opteron 82xx series. These CPUs are clocked a lot higher which is interesting for applications that scale badly and need excellent single threaded performance, but nobody is going to buy a 4S machine for such an application. It will be interesting to see if AMD lowers the prices of these CPUs or not.
Back to Barcelona, it also has to face the newly launched Tigerton (of which we are preparing a review). It seems that AMD's CPUs might conquer the high performance blade market easy: AMD offers 55W (68W TDP) quad-cores for about $700-$900, while Intel wants no less than $2300 for their lower power 4S quad-core. Our first tests indicate that a 1.9GHz Barcelona should outperform a 1.86GHz Tigerton, but more testing is needed. For now, we can only conclude that Intel has priced itself out of the 4S blade market. Then again, pricing doesn't always seem to be the primary concern with blades.
AMD also positions the 2GHz 8350 against the Tigerton 2.13GHz, which should allow them to defend the new found territory: AMD has no less than 56% of the 4S market in the US. Basically, we can conclude that AMD's pricing in the 4S market should be quite competitive.
2-Way Market
The 4S market has some great profit margins, but 75%-80% of the server market is 2S. Below is AMD's pricing for this very popular market.
So how does AMD's pricing compare to Intel's?
AMD positions the 2350 2GHz between the 2.13 and 2.33GHz quad-core Xeon. The 1.9GHz version squarely targets the 2GHz E5335. AMD has no answer to the X5365 and E5355, but currently those CPUs are offered in a higher power consumption band, so this is not the really the end of the world. The 3.2GHz and 3GHz Opterons might still make sense for some hard to scale applications if AMD lowers the prices significantly.

I don't deny people use MKL ... I dont agree that anyone targeting performance on AMD Opteron will use MKL. No one running HPL/Linpack for Top 500 submission would use MKL on Opteron. No one who wishes to test his Opteron for performance would use MKL to do so. No one wishing to have the fastest possible results from his Opteron will do so.Even ISV's now provide code that is optimized for Xeon and Opteron separately. Reply

Ok, point taken. Give us some time, and we'll follow up with new compilations of Linpack. Replykalyanakrishna - Wednesday, September 12, 2007 - link

and how offen do you read anandtechs Previews and reviewsunlike when intels core 2 came out all the hipe was real, to bad for AMD this time
this cpu is going to be good, problem is will it be able to compleat with Intels new cpu when it comes out
i still useing an amd system if your wundering and so all the rest of my pcs apart from my server as i just thow in an old P4 mobo to just file sharein house (all second hand parts apart from the hdds) Reply

I wonder if it would be feasible for AMD to take the Intel approach, and slap two of there new native quad cores together and release an octal core CPU in the near future. Or would they remain the multi-core purists they have become... Similarly I wonder if 2 65nm Barecelona cores could even fit under that heat spreader... or come in under an acceptable thermal envelope. ReplyAccord99 - Monday, September 10, 2007 - link

Page 8, 3DS Max 9 last paragraph:"Dual 3GHz Opteron 2222 is capable of generating about 29 frames per hour", but then
"potential 3GHz Barcelona will be able to spit out ~35 frames per second". I think that is supposed to be ~35 frames per hour. Otherwise that is an extremely impressive speedup! Reply

No, it is "per second". We used a Octalcore 2THz Barcelona there.... Thanks, fixed that one :-) Reply

Kentsfield has 2*143mm^2 dies. Barcelona is 280+ mm^2. Penry would be even smaller, 2*100 mm^2. So unless AMD can increase the frequency to 3.0+Ghz soon and price their new quad-core processors higher than Intel's, AMD would be still in red unless it oursouces Athlon 64 to TSMC. Reply
