mm cookies.. can I have one?

I don't understand how people could not want this technology when almost all desktop software is single threaded.

Hopefully it will have some nice results, but i through we were already doing this on a software level (OS - cpu wait states) maybe doing it on hardware level will provide better performance.

Not sure all the logic that would be needed to handle this could possibly fit in a bios update which is already full. The rumors say AMD requires a new cpu driver and an update to windows for their solution. That I can see, but a bios update? I doubt it. Everything sounds fine until you take into account running single core apps and apps that can actually use more then 1 at the same time. How does it switch from single to dual (or quad)? How often? What is the overhead of all that switching? When does it make a decision to stay in one mode or the other? Seems to be a lot of logic involved.

BIOS doesn't have any code in it other than the setting bootstap options, initializing the CPU(s) and setting switches on or off (including setting timings, variables, conditions, etc.). To think that theres "code" in the BIOS to handle this is ignorant of how things work. A BIOS update does little other than tell the CPU to enable to technology....that's why all it takes it a BIOS flash and Windows code and/or CPU driver update.

That's exactly my point. How can they put the needed logic into the bios. And logic is needed. Unless their solution is all single core or all multi-core. If it is then it's worthless.

They're not, the BIOS is just a toggle option to tell the CPU to enable or disable the feature.

Donbp, instead of shoving the knife in and twisting. How about actually waiting for results first?

You come off sounding like a rabid fanboy.

**PetNorth** · 06-23-2006, 02:46 PM

What matters.

@ FCG or Tony:

Have you enabled this feature in Bios rev 1181?
Have you run some single thread app?
and if response to these questions is "yes", then, Is there a perfomance improvement?

Good point, although I do hope that it isn't like HT, in the way that it works better for Single threaded apps but multithreaded apps suffer..

**_Eduard_** · 06-23-2006, 03:03 PM

So do they actually use both cores together or do they disable one, and then overclock and use the cache ment for both cores on the other one?

Anyway if this is true and it works, imagine a 3.5ghz kenthsfield 4-in-1 in superpi

14 conroe-gigahertz effective

**Donbp** · 06-23-2006, 03:04 PM

lol..Hey, I didn't start this thread that says it will be enabled with just a bios update. Yell at who did.

**Bloody_Sorcerer** · 06-23-2006, 03:19 PM

donbp, you're the one not realizing that the tech is already there, on the cpu, and all the bios is doing is flipping an on switch.

Yeah, maybe I misunderstood what people were saying. It sounded like they were saying that was what it is. As everything today has just been rumors and smoke I was getting a laugh out of it.

^ Lame defense after insulting everyone whos posted in this thread.

**sealion** · 06-23-2006, 04:14 PM

I'm starting to love these technology secrets. You're already excited bout getting a conroe/kenthsfield then they tell you with a bios upgrade you get an TWO conroes/kenthsfields. Oh the joy.

No. With a BIOS update you can simulate a much more powerful single core chip with a Conroe and a crazy-fast dual core with a Kentsfield.

**Flanker** · 06-23-2006, 04:33 PM

Lol, what he said. But yea, its awesome when something like this happens. Our performance just increased 66% in 90% of our apps without us having to do much about it, lol.

**grimREEFER** · 06-23-2006, 04:35 PM

i dont like this concept, u get the best performance with kentsfield when there are 4 threads at once lol, how hard is it to do that !!!

**Tony** · 06-23-2006, 05:10 PM

Guys don't forget AMD has a secret too, I have a feeling we may see PR's from both companies around 27th July or so...well im hoping they do..

I have no insider Info here, I have talked to neither Intel or AMD about this, i just read what gets posted and put 2+2 together, like Fugger says lets wait and see.

Regarding have a switched the option on...nope but FCG has,issue is we need the divice driver for XP to get it going and maybe a further bios update to straighten out some niggles etc...who know???

I know this much, it looks like both companies are pushing to better each other with secret tweaks they added into their latest CPU's, it can only make our experience of these platforms more enjoyable in the long run

Then I better make damn sure it is included in XS OS

**grimREEFER** · 06-23-2006, 07:59 PM

ok, if ppl are still buyin am2, idk what intel can do to stop them lol
they seem to have bested them in every concievable way, including having AMD's rumored tech lol

Yeah
Conroe -> more OC'able
Conroe -> 8 IPC, AM2 6 IPC (with reverse HT)
Conroe -> win

Still ... these RHT techs have gotta be lossy (in my unknowledgable opinion).... lets see some bencies

**BrownTown** · 06-23-2006, 08:32 PM

first you might want to see something other than a rumor...

Also, please everyone stop talking like a quad core @ 3G will be equivilent to a single core at 12G, life don't work that way, you'll be lucky to get theequivilent of a 4G single core even IF this technology exists (obviously there will be some instances where it is higher, but on average). Also, it would likely work like the origional HT where some programs actually run slower if all the specualtions end up to be wrong. Or, backround threads might get in the way and gum up the works.

Lol, best post summarizing Intel's current ownage I've seen in a while.
