AMD Zambezi news, info, fans !

Dresdenboy has found some new Geekbench scores of 24C and 32C Opterons,submited 1 day ago!

The older one is 1.4 GHz, not 2.1. Also, it only has 16 GB RAM, however I have no idea how much that affects those benchmarks.

Edit: Analyze this - http://browse.geekbench.ca/geekbench.../484217/317797

It's 2.1 Ghz.

3000 posts, quite a milestone

OK, we had some pictures of early AM3+ socket, and there was no way you could fit BD into Am3 socket:

you can see there is an extra hole in AM3+ socket, left hand side, left lower corner.
Of course maybe BD chips dont need that extra hole and AMD just cut it just for kicks. But where is the fun in that?

1.4Ghz is the idle state of the cores... Read the OPN of the early ES,the base clock and Turbo are in the OPN : ZS21245TGG44_31/21/2_2/16. Base is 2.1Ghz and Turbo is 3.1Ghz,part is 16C.
As for your second link,you are comparing an ES Opteron platform with a retail one. I used ES vs ES comparison.

That's the point, and that's exactly the story with AM2+ and AM3. Those pics aren't worth anything without knowing what the pins looks like on Zambezi.

By your reasoning, the same pic tell us that AM3 CPU's wont fit AM2+ because of the extra hole in the lower left corner....

Yes, and my point was that the "huge" difference between the two ES isn't worth anything as long as it's slower than the last gen.

[Manicdan]

not sure i like seeing the ES lose to a retail 24core

Exactly, that's why I can't see why it's even worth posting the ES - ES comparison.

It's worth because what we have seen so far are only ES results of both Opteron and Zambezi. And the difference between different samples running on different motherboards is massive. So ES performance varies a lot and is not final. That was my point.
Also,do you believe 16C Interlagos will loose to 12C Opterons in any of the tests ,especially in single thread test ?

No way. I just think it was worth pointing out to those who aren't used to geekbench, me included, that these are not results that are close to the final product.
You didn't even call the newer one an "ES", making it even more confusing.

Well I assumed people are able to read. This is listed when you open the first link in my post : AMD Eng Sample, ZS232545TGG45_32/23 .

[Mats]

I was talking about what you wrote:

Latest Opteron 2x16C @ 2.3Ghz result
Early Opteron ES 2x16C 2.1Ghz results

[informal]

So? Click on the links and you will see ES markings on both of the links. Why are you beating the dead horse? What I wrote in my short post is not important since I listed no scores. Click on the links and you will see the system configuration and exact numbers.

[Manicdan]

yeah i thought at first you had listed a retail chip, which is why i clicked, if i knew it was just another ES i honestly wouldnt have cared.

You expect to see numbers for retail chip before it is actually launched?

[Mats]

It's dead?


Edit: I'm just kidding. But It seems I'm not the only one who misinterpreted at first.

That's easy to believe when Cray already got their first box of chips. Not that I think it will be available that same day, but the question is when.

[Manicdan]

i only expected there was a reason you didnt call it an ES, and since we all saw a box of chips go out, its not unbelievable to see retail samples out there. these things are still WAY too slow, and it would be nice for some good news for once.

well i thought too that maybe it was a retail since they started shipping earlier this month(7th if i remember correctly)

[demonkevy666]

demonkevy666 Isn't NB affecting just the main memory? Maybe it affects L3 but I don't think L2 is at that speed, it should be at cpu frequency as was L2 in K10.

i wasn't lookin @L2 cache ever lol the nb can also effect core to core

flyck If its a hardware issue and they can fix it then the performance should noticeably improve and it would explain the mediocre performance until now.

edit: on the Aida64 product page it says its fully optimized for BD so I would think its a hardware issue or maybe this is the throttled thing in bios chew* mentioned.

bulldozer has a lot of power saving features compared to phenom II

[FlanK3r]

for what Im curious now, how good will be OC at uncore .

[xdan]

I'm just curious, i knew that 4 models where suposed to be launch not three.
The missing one is FX 4xxx quad core. May that his performance not worths to launch comparing to X4 955 which is at 112$?
Or may be AMD didn't even make a derivate design - FX 4xxx quad should be more a BD 8 core split in half.
Because the 6core FX 6xxx it's clearly just an 8core with 1 module broken.

[Manicdan]

the missing 4100 sounds like they are not making enough chips to need a new bin, if they are getting chips that have 2 broken modules that can only be sold as 4100s, then they should be around, but if there are just not enough of them it could be too soon to include them. or they could be worried about people unlocking them and not buying the 8100s initially. or yields are great and there is no market for half broken chips cause all the bad ones are still good enough for 6100s.

[Aaronage]

Don't compare Solaris Geekbench results (the Opteron 6176SE system) to Linux (Interlagos system)

The variation in scores between Windows/OSX/Linux/Solaris can be huge with Geekbench. The scores shift by a not insignificant amount with each minor update to Geekbench too. I've seen a massive increase in the Blur Image/Sharpen Image tests on K10 going from Geekbench Win 64 2.1.13 to Geekbench Win 54 2.2 (thanks to the new compiler used).

Geekbench scores across different operating systems and different Geekbench releases should not be compared.

Thats true but what are you trying to say with this? That they have some power saving feature for cache enabled non stop and thats crippling the performance or something like that?
