AMD Zambezi news, info, fans !

[chew*]

I think that any info other than what I or AMD have personally offered which is not much if any can be discarded until further notice.

There are still peices to the puzzle missing that I can assure you 99.9% don't have yet regarding CPU rev and bios support and agesa.

To sum up BD facts

BD is physically a 4 core 8 thread part.

It has no coldbug

Samples can bench at 5+ on stock cooler, 6+ on phase change and 8.4 on lhe.

And most important of all SATA works

Like i said before the joke is on that guy we won't name, he was sent intentionally quite possilby the worst chip ever produced. 6.4 on ln2,
or he needs to learn how to OC, 6.4 is my validation speed on phase change......he who laughs last laughs best.............

What I remember from this long thread is Chew's comment regarding the 8 cores. It's quite funny how people look at the performance as this 'eight-core' chip and scream it's really bad, but if it were 'four-core with HT' people would say it's doing okay price/perf comparing to 2500K/2600K.

Even though it's the exact same product, opinions are different.

Let me quote you for emphasis.

Well, you can imagine what the complaints will be on day of release/actual benches are released, "They need an 8 core to perform on the same level as a quad core!"

(sigh) Fun times lie ahead.

The "AMD FX CPU (...) | August 31, 2011" document this guy talked about is not the final performance version chew* ?

Not sure what you are referring to.

[informal]

Not sure what you are referring to.

He is referring to reviewers guide given to press,I think.

So a reviewers guide meant to accompany B2 F die

Oh no, Franck7511, another Bulldozer negativist from France. No offence Olivon, really, but what`s going on? Has AMD hung a giant Bulldy billboard over Eiffel tower or what?

That's not my fault

I don't know him except that's more an AMD fan usually. The guy seems disappointed from what he has seen. That's all I know I promess !

And keep cool guyz, there's no "Bulldozer vendetta" from France. That's in your imagination

[metalazzo]

I would prefer that :p

According to VR-Zone CB10 results, BD module scales very well with threads ~70% with second thread on module.

For eg. there is xCPU result for FX8 17800 CB10 points. For 1CPU is only 3450-ish points. It is ~5.16x scaling factor. Six core Thuban without turbo has scale factor ~4.9-5. According to Amdahal's law hypothetical 8th core Thuban could scale approximately ~6.25 for eight full cores. That is 21% more than CMT, which means that CMT scale pretty well. Problem is obviously with IPC or low/inaccurate frequency or something other. Per module with single thread execution, according to VR-zone result 3.1 GHz without C6 has same or little lower performance than K10 core, per clock. To reach hypothetical X8 K10 multithread performance, BD module must have 20-22% better IPC than Stars core.

cant wait for this!!!

[Mechanical Man]

It just occured to me, that most games do have only few heavy threads on them. With 8 core bd, smart os putting heavy threads on different modules and using rest for light ones... Turbo all time for heavy ones and light ones getting processing power they really need not more... That is not bad. Now only if ipc is on spot.

I think the os plays most important thing in here for results.

Hmm.. Maybe i'll buy the 8150 instead for the wife so i can play with it first. Thank you chew for making me spend MORE money

when you say 6+ is possible on phase .. do you mean single stage -30c or so ??? or closer to dry ice territory in the -50c or so range ???

[BeepBeep2]

Video shows 6 gig at 30 suicide, -45 range I'd guess you could bench that? Dice should be able to hold -50 to -55
