TFS the pics
any BD Demo over there? they say Asus would have one
keep us updated
remove pci and add more pcie- 1x slots cmon :/
The front end uses vertical multithreading. One thread per cycle.Quote:

Thanks for pics imamage :up:
I like what I see for Llano there!
Plenty of choice, different form factors, CF support, lots of SATA :clap:
PS. One more thing I noticed on Asus A75 board is feature called GPU Boost! I wonder how much it can overclock and of that means we will have BIOS access to tweak CPU and GPU frequencies independently of each other? Anyway seems to be the case :)
BULLDOZER?

performance lower than expected?

I can smell the bull:banana::banana::banana::banana: but I can't tell where it is coming from; the site quoted or AMD, where they are laughing their heads off. :shrug:
I found this article to be interesting. If bulldozer is struggling with floats, then we have trouble ahead. Integer workloads are incredibly important for many tasks, but floating point can't be ignored. Sticking these into a Cray won't be very useful with poor float performance ;). Any ideas why this might be the case? Mostly I'm curious as to whether this is the performance issue or the bug (or both) that they talk about. My guess is that the performance is lacking in floats due to heat. The FMAC is shared, and probably gets crispy in large workloads while integer units are more evenly distributed about the core...Quote:

As for the new board pictures, it irks me that ASRock had the gall to do that -_- Rebadging the Deluxe5 as the 990FX Extreme4 is one thing, but passing it off as a Fatal1ty w/o even as much as a color change is bull :\ There is barely even a design change to the board either! STILL are using that same blasted NB heatsink that prevents the usage of the first PCIe x1 slot, with anything except a very short USB card or NIC at least! >_<
I doubt that this is a temperature problem.Quote:

The module's two 128b FMAC units (each actually consisting of two 64b/80b FMAC units) are sitting on the left and right ends of the FPU area. You can see the split register file (bright rectangles).
So those possible hot spots are as far apart from eachother as possible in the given area - about as far as the integer execution units of both cores (in the upper parts of the int cores):

That BSN article smells of BS without the N. AMD banks on GPGPU next year,in BD+? Yeah right. BD's FPU is not weak.There may be some bug,but unless AMD totally screwed the performance estimates in their design process,there is no way the new flexfp is going to be subpar to Thuban. Also the article claims that BD is superior clock per clock than SB in integer,which is fishy to say the least.It's not impossible of course,but one would expect that 30+% IPC improvement by just going 4wide and improving prefecth is a bit on a far fetched side.
All in all,we should know more on Wednesday. AMD must correct their public roadmap if they hit a delay,there is no way around it. They did contact BSN 1 week ago and said no delay to Q2 roadmap.Now ,all of a sudden,few weeks from launch ,there are some major issues with production silicon and they need a respin.If this really was the case,AMD would have known all of this back in March or April,not 2-3 weeks before launch which is the time when product is being shipped to major resellers worldwide.
Frankly, the only weight I give to it is that he mimics that BD will be pushed out, the rest of his analysis/commentary is, at most, questionable.Quote:

EDIT: There are really 3 tech sites that give good analysis of compute architectures -- Arstechnica, Jon Stokes -- Realworld Tech, David Kanter -- and Anandtech, Anand Shrimpi. All 3 have educational backgrounds on the subject -- as I understand it, Stokes and Kanter actually roomed together in college. I would not trust much of what Theo has to say regarding this topic.
Do you know if they account for the Vss gating footing as part of the module area? I would suspect so since it is part of each module.Quote:

I don't know that but would assume the same.Quote:

Damn, it's painfully obvious how closely related K7 and BD really are. BD is one heavily modified K7, but it's not completely ground up. One BD core (not module) is pretty similar to a Phenom core.Quote:

The reason for this is the fact that second generation Bulldozer (so called Bulldozer Enhanced) will unite the Bulldozer cores with Radeon HD graphics which will take over the floating point operations as much as possible through OpenCL and other GPU Computing APIs.
See I just can't see AMD making that move. There wouldn't be a huge reason for companies to use a 'Dozer in their current C32/G34 systems if they won't be an all'round upgrade for them... My understanding was the 2nd Gen chips would move over to a new socket, meaning that there really would be little reason to upgrade now when a future upgrade wouldn't even be able to utilize the same socket anymore. I mean maybe the C32 equivelant chips could move over to G34 when they get a GPU, and that'd be pretty cool, but how likely is it really? :\
And that would be the part which hints the article is BS, without the "N".Quote:

While I can see the issues with FP code BD might have due to having only one FP scheduelr per module and with 256bit code, it shouldn't be that bad if Cray chose them for their blades...
Phoenix Technology News May 31 News, in today's Taipei computer show, AMD senior vice president of Products Group and general manager of RickBergman dialogue with the Phoenix Science and Technology, said, Fusion will be released tomorrow in the product for the Tablet PC;
对于备受关注的Bulldozer（推土机）产品，RickBergman向凤凰网科技频道表示，该款产品 将可以在今年夏季看到。 The concern Bulldozer (Bulldozer) products, RickBergman Technology Channel to Phoenix, said a product that will be able to see this summer.

Rick Bergman, this guy already said bulldozer is an early summer product.Quote:

Not that hard to put together this: even the relatively legacy free G34 can't handle the next generation CPU's, so how can anyone expect AM3+ to do it?
Why should Komodo stay with PCIe on on a separate NB? To please AM3+ owners?
http://translate.google.com/translat...545%2F&act=url
Still no one wants to believe it. "Komodo is not an APU blablabla.."
And even if there's no integrated graphics, there will be integrated PCIe for sure, which means a new socket.
I can imagine all the whining when the roadmaps for Komodo shows a new socket.
I know I'm repeating myself..
Hate to say it, but I told you so.

I was under the impression everyone knew this, bd ver 2 will have a new socket.There was a slide about it last year, cant find it now tho.
It showed "current" BD and in middle of the 2012 it was "BD ver 2" with some new socket.
And it showed integrated pcie .
BTW,
from this AMD BLOG, besides it says H1 2011 for bulldozer (may be obsolote by now).
What i find interesting is that sepang has triple channel memory ,and thats a single die socket, kind of intel 1366.Maybe theres gonna be desktopish version of that.
No IGP.Quote:
“Komodo”
Market: Server and Performance Desktops
What is it? “Komodo” is AMD’s next generation CPU and is primarily intended for servers and high-performance desktops. “Komodo” will feature next-generation “Bulldozer” CPU cores and, in desktop PC platforms, is designed to couple with DirectX® 11 GPUs to provide enthusiast-level system performance.
Planned for introduction: 2012
Thanks for the response. Granted, it was an idle musing, but very unlikely nonetheless :). Do you have any hypothesis? Again, I was putting some stock into the original article, which may be my issue in the first place...Quote:
