AMD usually hide their new chips until announce date

Kent will have 280 square mm chip surface, K8L - only 150 sq. mm

That was an old estimate. A more recent estimate from the same person is 283 mm^2.

thus Kent and Deerhound have equal chip square?

maybe sooner then we think ? remember how long ago that the K8L was suppose to be taped out ? well according to this , it takes 12 weeks from start to finish for a amd wafer , , i think that my math must be failing

How AMD bakes its 65 nano Barcelona cakes

Basically, AMD can automate the testing and incorporate the feedback on the fly. When you decide to do 10 per cent more on step 37 of 91, three weeks into a 12 week process, getting accurate and timely feedback is essential. What APM does is allow AMD to pick a set of wafers and apply the special sauce, and track them at every point from then on while cataloging all the metrology details. If it works, and has good yields, it can be made part of the permanent mix very quickly.

either my math is getting bad , or my memory is getting bad

They have to do more testing and build volume for the launch, I doubt we'll see em' earlier than 2Q 2007. Die size seems a little large but doable for AMD, hopfully they can get it down to something a bit more reasonable to improve thier margins.

It's only 150mm^2, that's a lot smaller than the dual cores they make now. AMD should get very good yields. You probably looked at the picture and forgot the quad core is 65nm. This makes it really only half the size it looks like in the picture compared to the dual core.

If these pictures are of a 300 mm wafer (and they appear to be), then it's closer to the 283 mm^2 accord99 mentions.

These are pictures of their quad cores. 283mm^2 makes sense

I'm really confused by all these AMD core revisions...

nobody tested anyone yet??

i really would like to see a processor the nock out the conroe!! :P

Wouldn't matter since each core has a seperate PLL
thus you can overclock each core to its max

i was under the impression that they all had the same pll, but could adjust multiplier and voltage independantly..

either way, the rough effect is the same :D

Earliest you could expect some leaked benches would be Dec. this year or Jan 2007, I'd lean towards the former rather than the latter, despite all the naysayers who said they couldn't pull it off it appears that AMD is following thier schedule and will be on time.

they say next-gen AMD cpus aka K8L will be 40% faster than todays K8, and thus 20% faster than C2D (Yorkfield is just Kentsfield shrink with SSE4)

At stock speeds.

What about overclocked? We all know conroe overclocks like crazy, and unless these new AMD chips can do the same, I don't see them catching conroe anytime soon :(

true that!

well for bragging rights that is. Fortunatally most server farms run at stock frequencies.

in multithreaded apps (rendering mostly) it will spank every conroe even if you OC the later.

tho the hkepc list has some mistakes.

Rev G Quad Core and Rev H Quad Cores are different.

Rev G Quad Core is merely 2 65nm dual core dies on one proc, while Rev. H will be native quadcore i.e. designed from the inside out as a quad core model.

The only match Intel will have to Rev H is Yorkfield. Conroe, penryn, kentsfield will all be architecturally behind the K8L aka Rev H. The advantage to Penryn in 2008 being the ability to have an Octa-Core Core2 model with the same die size as the smithfield (ironic)...how pratical that'll be knowing the yorkfield will be out for a about 8 months by that time)

PLEASE PLAN CAREFULLY FOR UPGRADES WITH THIS INFO... Lots of suckers are gonna be going around shouting "The K8L are here, The K8L are here" when the first quad cores are announced.

Increasing that confusion will be the fact that AMD will introduce some Rev H products with two cores disabled, hence a dual core Rev H.

Perkam,there is NO RevG QC!MCM isn't possible with K8 since two cores can't share one mem. controler...
RevH is the only QC design and the rivals for Kentsfield will be 4x4 systems(at least while there is no K8L in those configurations)

The official launch of dual-core Opteron occurred on April 21, 2005. On the same call Meyer announced that that the native quad-core would launch in the middle of 2007 -- suggesting the non-native quad-core Deerhound designs may come earlier than expected or not at all.

Something I've been shouting about since March...there ARE non-native quad core designs in AMD's test labs...they just haven't taken a firm decision to launch it so close to the K8L launch as the kentsfield will be unarguably faster, which could cause a long term market stigma of ALL amd quad cores being slower than ALL intel quad cores, thats not to say that the market is stupid...just that the assumption makes it easier to make decisions :p:

And with Rev H (K8L) coming in Q2 or Q3 '07, AMD will not have the performance lead for long until it is challenged by Yorkfield (please note I said CHALLENGED, we have no indication yet how K8L and Y-field will compare in IPC and raw clock speed).

So you do know how high AMD can clock RevG??
If you don't know,how can you tell AMD can't challenge C2D?
I'm speaking of def. out of the box comparisons,like 3.4GHz Brisbane vs 2.93 C2D ie.We saw that there are 3GHz Windsors coming this Nov.,so Brisbanes that will be Rev G2 or G3(hypothetical numbers) and will incorporate new and improved trensistor mix on 65nm could probably easily hit 3.4GHz(and btw,don't bring those roadmaps showing Windsor based FXes-64 or whatever- in Q3 07 into this discussion,since those are highly inaccurate)

Perkam,as I read that,it says that they(dailytech) seems to think he suggested that,not that he actually said:" There are non-native QC on the roadmap in 07".Dailytech has a vivid imagination :p:
Read that again,maybe you will see it too :)

AMD and Intel have both confirmed that their nex gen native QC designs are launching Q3 '07...

All this talk about AMD "will be behind" is crap...it'll on par with the year...Conroe allowed Intel's crown to remain for 1 year, while AMD's lasted 3.
