Can AMD respond to Conroe

[conundrum]

http://www.anandtech.com/tradeshows/showdoc.aspx?i=2713

Looks very impressive but not available for six months yet. Will AM2 be a match for this. When do AMD switch to 0.65 microns ?

 

[Jamie1984]

conroe looks promising, but 6 months is a long time...who knows?

 

[NathanE]

They won't be able to match it whilst on 90nm, that's for sure.

 

[welshtom]

so whats the conroe and Pentium D? where do they differ

AMD VS Intel

Hi, All

I think Intel has given a promising preview, but personally I think AMD is going to kick the living day lights out of intel.

Intel gave its new chip a good name "Con"roe

Thanks

Am I right in thinking the Conroe is simply two Dothan cores slapped together? It just seems like it as dothans have 2mb cache and these have 4.

no thats yonah.
Conroe addresses a few problems the dothan had and reworks it a bit.

i cant understand what the pentium d is

tom - very different, much more work per clock, - you should already know anyway (shorter pipeline as far as im aware)

as if amd can respond to something that doesnt even exist :/


pentium d is 2 p4s slapped together

I really doubt AMD don't have something up there sleeves.
there current chips on low voltages and low temps are fast. And when overclocked they are awesome.
I reckon there is a high chance that AMD have got many 'special' chips lying around that ill be able to keep up, atleast until they move onto 65nm.



As far as Pentium D vs Conroe,
Its the dualcore equivilent of Pentium 4 versus Pentium M.
More done per clock, lower voltages and temps.
But being a nice cool chip at low clocks it can be clocked up to around 3GHz without being extremely warm.
Conroe is also 65nm.
slightly faster bus speed too.
Afaik that is all that is different.

I think that's essentially it, but rather than the Pentium D where they had to communicate over the FSB (= bad) they have a direct connection in a similar way to the X2s. Each core is a bit more enhanced compared to a Dothan though as far as I'm aware.

so what is this 65nm and 90nm people speak of? laymans terms please!

It's the size of the smallest feature on a silicon wafer, smaller is generally better as it means you can build transistor's smaller and as a result they can go faster and use less power.

so, why havent amd moved onto 65nm then? or is that what they are gonna do with the next generation of cpus?

 

[Zefan]

On smaller fabrication processes like these they'll need to work on it a long time to get any sort of acceptable yeild chips wise. That makes a move to smaller nm very pricey indeed. Worth it for clocking and performance though

 

[Jamie1984]

so in reality Intel being the bigger company could stay one step ahead of amd? getting the gist of it i think

AMD usually move onto the lower manufacturing process a year after Intel do, they don't have the same money or facilities that Intel has.

AMD's 65nm cores are due out in 2007 as far as I know.

If they have a decent design Intel should always be ahead of AMD, they have many many more fabs & a capital budget that AMD can only dream of.

Problem is, its been a while since they had a design that could compete although hopefully that should change soon.

Intel are installing equipment for 65nm in a number of fabs (4 at the last count) to be ready for mass production of 65nm, AMD installing equipment in 1 (the new Fab 36 in Dresden).

 

[Jamie1984]

wow, seems a bad situation for amd...cant say im displeased with them in the past tho...loved my athy xp and my 64bit 4000!

 

[mcmad]

its not bad as such, its just difficult for them to fight with volume

 

[m3csl2004]

yeah you have to remember a lot of intels sales go to oem's - amd do not have the capacity to do this, and therefore, make less money generally

2007 is 65nm amd, lets hope its good
