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.

lol "we believe this is native 8 core" and "this confirms our earlier report that amds 8 cores are native" heh self confirmation... tabloid crap
 
Intel will do what it does best by then, getting out quick solution. They will slap two quad core chips. Besides all the argument about Native and MultiChip design done to death by fanboys, Intel has already proved that it doesn't make big difference... at least in current form of available technology. It may make difference as number of cores increase.

Anyway, I'll hold my judgment till we get to see something in real. No point blowing our brains over rumor talks. :)

if i m not mistaked present quad cores of intel are same na 2 dual cores attached side by side
 
than for 8 cores sticking 4 dual cores side by side will dissipate more heat......i guess change in architecture only solution
 
In a direct answer to Intel's Nehalem AMD is showing some teeth as well. AMD currently making the preparations for a worth-mentioning Nehalem competitor. The chip manufacturer's upcoming 45-nanometer chips in the Deneb and Propus families will undergo a significant micro-architecture redesign, also known as K10.5 Rev. D.

The D silicon stepping in the 45-nanometer process will be code-named Hydra and is alleged to be AMD's true response to Intel's Nehalem CPU micro-architecture. This silicon stepping will introduce an L2 cache level of 1MB per core, which means that the upcoming processors will enjoy twice as much cache memory over the existing K10.5 silicon.

More than that, the new micro-architecture will also bring the much-hyped High-K metal gate technology that has been jointly developed by AMD and IBM using 45nm SOI (silicon-over-insulator) cores. The first 45-nanometer SOI cores, however, will be introduced earlier, in both Deneb and Propus chips. Hydra will also bring a huge, 6 MB L3 cache pool that will be shared among all the processor's cores. The new chip is expected to hit the market in at least eight-core configurations, although the company is likely to introduce them as eight-core native designs, rather than the recently unveiled MCM (Multi Chip Module).



As far as the brute computing performance is concerned, it is estimated that Hydra processors will be able to deliver stock core frequencies of over 3 GHz.


It is currently unknown whether it will be as overclockable as Intel's counterparts, but this is highly unlikely to happen, given AMD's conservative stance when it comes to tweaking its chips. Intel took the same approach with the Nehalems, and rumor has it that only the Bloomfield-based high-end offerings will be ale to go beyond the default clock speed.

The Hydra chips will arrive on the market in mid-2009 or even later and in the meantime, Intel's Nehalems will be the only high-end alternative.
