AMD Zambezi news, info, fans !

Its not the 19th in the US though

oh i forgot some of us are living in the Twilight Zone

[tbone8ty]

was just curious as to what was/is the factor in the delays? (more focused on cpu arch. not production or outside factors) if there was any...

i understand the first couple steppings were sub par, but what part of the architecture was to blame? or was it bad yields? or just couldn't reach desired clock speeds?

dont wanna start another couple of pages of arch. wars...it is just innocent curiousness.... if anybody knew some solid evidence.


hopefully BD will be what everybody hopes and we will look back on this thread and

I am gonna take the under on this one. FP benchmarks are less interesting except in the HPC world. ~90% of what your CPU is doing all day long is integer. FP has long latencies (deeper instructions) and is really only ~10% of the work. So speeding up FP might look awesome on SPEC FP benchmarks, but for desktop apps and most server apps, it gives you little or no noticeable impact.

I disagree, FP is used extensively for gaming, and I'm not talking about 3D rendering (GPU has taken care of that for the last decade), rather I'm referring to physics. Physics accounts for a huge amount of FPU utilization in modern games. Physx would be the out here, however it's rarely used, and Radion has no support for it.

So if all you do is basic computing, i.e. internet, email, word processing. Then by all means just dismiss FPU performance.

This may help your argument: http://www.realworldtech.com/page.cf...0510142143&p=3

However, there was some news some while back that Nvidia was recompiling the Physx API to move to SSE code, and take better advantage of multicore architectures, not sure if that ever panned out though....

is that just physx or would openCL based bullet physics be the same way as heavy FPU based? it would be dumb for amd to support opencl, then to be way behind in using it (unless they know that komodo will lets its gpu handle it very well).

I don't see any "metal box" thingy in Local store
So No Bulldozer yet

always keep us updated as Hong Kong mostly gets the new stuff first

Anyone have any thoughts on the Gigabyte 970a-UD3 with BD? Seems like a very good board for the money, 8+1 power too

given the ipc of those applications and the #fpu ratio. i don't see a big problem. Low ipc shows alot of dependant ops or lots of bubbles. So while it is fpu intensive code it isn't really intensive for the fpu. So longer latency would affect the thread throughput, another thread would not interfere with the performance. (which is also and advantage). Biggest problem is that the code uses an obsolete marked instruction set for x86-64. So in SSE this would or should run pretty decent on BD single threaded and very good if it is multithreaded... but given the x87 dependancy i'm not sure how BD will perform in that. Might be pretty bad if they really disregarded those legacy instructions.

this code would run great on K8 architectures. (if they can predict and feed enough to their execution resources)

That's the board I was looking at replacing my current one with.

Question for JF-AMD

I have got a supermicro H8QGL-6F ( quad socket motherboard ) with only 2 opterons 6128 HE. Now i want to buy two others 6128 but not HE. So my question is : is it possible to mix opterons 6128 with 6128 HE on the same motherboard ?

Thanking you in advance for the answer .

They pulled all the listings over the weekend.

Sabertooth has the same bios options, just not as good onboard sound and doesnt have the special software stuff. From what I remember they both have the same VRM stuff so you should be able to get the exact same overclocks. Sabertooth also has a 5 year warranty instead of 3, however it doesnt support quad-SLI/vrossfire

So you can't run two dual GPU cards in the Sabertooth even though they only take up 2 x PCIe x16 slots?

Also, why is the warranty 5 years on it? As far as I know most Asus boards are 3 years warranty.

He's incorrect. From the Sabertooth Product Page

Quad-GPU SLI and Quad-GPU CrossFireX Support!
Flexible Multi-GPU solutions, Your Weapon of Choice!
SABERTOOTH 990FX brings multi-GPU configurations through both SLI™ and CrossFireX. This motherboard features the powerful AMD® 990FX/SB950 platform, optimizing PCIe allocation in multiple GPU configurations. Expect a brand new gaming style like you’ve never experienced before!

that's cause sabertooths are made to last even in harsh conditions

Certified for Tough Duty
Get rugged performance even in the most challenging conditions with robust TUF chokes, solid capacitors, and MOSFETs--certified through third-party, military-grade testing. TUF Chokes, also known as the “Alloy Choke”, is a made of a compound of various types of metal instead standard iron, enables the support of up to a massive 40A of rated current, 25% higher than conventional component. Furthermore, the single piece packaing also elimates the emission of virbation noise, delivering superb charactoristics as well as durability under extreme conditions.

5 Year Warranty

The ultimate reliability of TUF Series is not only based on advanced thermal design, military-standard components and strict reliability tests, but also on the 5 Years Warranty* which is proudly provided.

The Sabertooth board is tuned more for reliability than performance like the ROG boards...

Hey what I wonder is when they are going to release an actual SB950 driver. Im sure the SB850 driver doesnt fully support the 950. Any thoughts?

Last time i checked all CPUs had to have the same vcore. That would not be the case with HE and non-HE CPUs.

I would prefer the older 870A-UD3 Rev. 3.1. It has better VRMs (low-rds) and more connectors (IDE, eSATA). Furthermore, where I live, it is a bit cheaper, too.
The only thing which is missig is the VRM heat-sink, but well, the low-rds parts are getting less hot:

Ok, thank you. Bad news.

Do you know where i can find more information about Vcore for these magnycours opterons ?

Hi,

According to this page http://www.overclock.net/amd-motherb...tion-list.html

GA-970A-UD3 has low-rds VRMs too... plus heatsink

Think I'll get this cheap baby soon !

Sure thing
I want to have some fun with Bulldozer too
My ASUS Crosshair V is waiting for Bulldozer

[imamage]

Until 8PM local time
No sight of Bulldozer at retail yet

No news
