Damage & crew? Doing a review of the 90nm 939 chips?

Postposted on Wed Sep 29, 2004 12:41 pm

If so, these are some good questions that I'd love to see answered.

Ok, clock for clock, does the 90nm CPU actually outperform the 130nm CPU? What if the 130nm CPU had the 1 meg cache?

have you heard of NDA?

Are there even any architectural differences between the 90nm and 130nm parts? There was a big difference in the P4 because the Prescott had some major changes in the design along with the process shrink.

Nope. This is just a die shrink.

bummer :wink:
it's new enough, that they shouldn't really have many changes

Thanks to Buck_Naked from our forums to alerting me to this information on AMD's 90 nanometer Athlon 64 processors (there a link to benchmarks as well):

* Full SSE3 implementation
* Improved hardware data prefetch mechanism
* Increased number of writing combine buffers (D0 stepping A64's can now combine up to four non-cacheable streams compared to 2 o­n the C0 and CG stepping A64's)
* Improved o­n-die memory controller with more advanced open page policy
* O­n-die thermal throttling
* Black Diamond Low-K technology (slower less power hungry transistors in less used sections and faster and more power hungry transistors in frequently used sections of the cpu)

has this stuff been verified? sse3 support?

I should know very shortly and will be happy to confirm/deny.

i have heard they get hotter, seems to do with the smaller die having less area to dissipate heat is what they are saying

It has also been rumored that the new 90nm 3000+ and 3200+ do not have these features, and that they are reserved for the 90nm 3500+. Just telling you what I heard. I'd like to know if the 3000+ support sse3. Are there ways to test for the other features mentioned?

I doubt this. AMD bins its chips & having 2 different chip designs wouldn't be very cost effective..

they wouldn't just 'throw away' chips that have sse3 support, but dont mee the 3500+ rating. Then again, they could disable sse3 support somehow and label it a 3200 or 3000 :-?

There's certainly nothing I've foud on the AMD site to verify this. Their most recent Tech Doc (Sept 14th) is a builder's guide that specifically mentions SSE2 but not SSE3.

Which is not to say it's not possible -- they may be emargo-ing their tech docs until all the NDAs are lifted.

Is TR the source of this report? :)

We are trying to confirm whether these changes are present in current 90nm Athlon 64s.
