Deneb vs Agena..feel Free to "speculate"

[gallag]

This may explain why leakage is reduced:

Special thanks to RiverRicer who provided the SOURCE

Will it help leakage? Also, This is a card they will play in the future and will not be a feature on AMD45nm for a while so it is slightly irrelevant.

1.168 sounds really too low. But on my System (9950BE on 790gx Gigabyte) AOD shows wrong voltage an CPU-Z shows the right.
But I can´t believe... So let´s see!

it says "later"...it doesn't say the low-k dielectrics are going to be present in the initial 45nm products.

Will it help leakage? Also, This is a card they will play in the future and will not be a feature on AMD45nm for a while so it is slightly irrelevant.

CLARIFICATION: To be clear, I was only speculating about how the OC'r who provided the snapshot could achieve 4.0Ghz on air at 53C under 4x 100% load. If this result is reproduced, then there must be new design elements that reduce leakage and heat. I just wanted to highlight a possibility.

My main reason for posting this was RiverRicer's source. These design elements are clues as to what we might see in an FX version of Deneb, e.g. high-K metal gates.

High-k is planned for H2/09, i.e. for the Istanbul 6 core chip. AMD stated this on one of the last press conferences.

hhhhmmm let see all of deneb's new features

1. HT3.1 3200mhz (like Icore7 i 3200mhz too) helps memopery mostly, maybe a little with GPU.

What Du you mean with "memopery" ? Mem speed ? That is totally unaffected by the faster HT3 speed. Only exception are coherent memory transfers in Multiprocessor setups, but we are speaking about Deneb = 1P; not Shanghai, dont we ?

To the 4 GHz screenshot:
It is already from July:

Are there no new ones ?

AMD K10.5 Hydra to challenge Nehalem

To have 1MB L2 per core

After Deneb and Propus 45nm K10.5 Quad-cores AMD plans to change the process and improve the existing K10.5 cores. The new process is called 45nm K10.5 Rev. D and it will bring high K to 45nm SOI cores. K10.5 Rev. C is the 45nm SOI process that AMD plans to use for Deneb and Propus 45nm cores. AMD calls Rev D cores Hydra and these are the chips that will really go against Nehalem.

The test production of these rather interesting cores will start in Q1 2009, but we expect to see the production cores by the middle of 2009 or a bit later.

The new K10.5 Rev. D supports 1MB L2 per core, which is twice as much as in current K10 CPUs and 6MB L3 cache memory. The most important feature is that it will be able to get you eight cores and we believe this is eight-core native design and not MCM (Multi Chip Module), as many have suggested before. This confirms our earlier story that AMD’s eight cores are native and you can read it here.

The new chip should be able to hit clocks in excess of 3GHz but we will hold our breath until we see it. This does look positive for AMD, but it still means that Nehalem will probably be the market leader for at least six to nine months before it gets a real competitor.

I dont believe this fuad story, cause the 1MB L2 Quad Core got deleted on the AMD Roadmap after AMD switched to the 6 Cores.
Its old code name was "Montreal". Furthermore Fuad sometimes writes really lots of trash ..

Besides that Spec Numbers for dual / octo Shanghais are out:

i don't believe fud period. they are just posting things over and over. most of the time they take both sides deneb sucks, deneb is good. i bet if someone tested the accuracy of their articles it would be below 25%. i don't even care about news anymore theres nothing else to say except for performance results and with shanghai coming out and deneb coming out soon that could be coming in. but really why does it matter? everyone is gonna get deneb because we all know how great it is going to be.

everyone is gonna get deneb because we all know how great it is going to be.

Will we though? I have been an AMD fanboy since the days of k6II. I am now wanting/needing to upgrade but am waiting for fresh benchies and pricing of Deneb. If it fails to impress (which has quite honestly been the AMD trend lately) i will do the logical thing swallow my pride and get the base nehalem offering since I am already needing a new board, ram and cpu.

For the sake of a competitive market, i hope we get pleasantly surprised here. But personally, i am not expecting anything spectacular.
