Advanced Micro Devices will disclose more details about its forthcoming code-named Bulldozer micro-architecture at Hot Chips conference in late August. Potentially, micro-architectural details may reveal projected performance of the forthcoming multi-core central processing units.

In the program of the Hot Chips conference AMD itself describes Bulldozer core as “a new approach to multithreaded compute performance for maximum efficiency and throughput”, which means that the forthcoming core does include a multi-threaded technology, which may be completely different from implementations from companies like Intel Corp. or Sun Microsystems. AMD plans to present the Bulldozer details on the 24th of August, 2010.

Based on the information provided by AMD during its annual Analyst Day last November, the first Bulldozer chip code-named Zambezi (which belongs to Orochi family, according to the firm) will feature eight x86 processing engines with multithreading technology, two 128-bit FMAC floating point units, shared L2 cache, shared L3 cache as well as integrated memory controller. AMD also states that the new CPU will feature “extensive new power management innovations”. The new chips that belong to Bulldozer family will also support Advanced Vector Extensions (AVX) that support 256-bit FP operations.

Based on a diagram that AMD demonstrated in the past, the company intends to dramatically improve multithreading performance of its CPUs with the help of two INT schedulers, an FP scheduler and separate data caches for each of four cores should do the job very well.

AMD has not released any data regarding performance of Bulldozer chip, but since the chip designer positions the unit as a solution for high-end desktop and server solutions in 2011, it does expect this 32nm SOI with high-k metal gate power-house to be a high-performer.

so, the announcement is that they will make an announcement with actual specifics in late august?

For how long now have we been hearing/readind about and waiting for Bulldozer? For AMD's sake, it better be worth the wait. And for us consumers too, as Intel needs to be kept honest.

There was no announcement from AMD, its just the published lineup from Hotchips, Shilov tries to make it as an announcement but fails. Hotchips is an all stars highly technical conference, not some overclocking garage tech event, so get your facts straight, AMD along with many others will present some extremely technical information, there will not be SuperPI or 3DFart kid runs.

Multi Threading from AMD.. Well, I think it would be done better than Intel's but I don’t know if AMD will be able to improve performance OVER the level of Intel's Nehalem architecture. Sure .. getting better IPC is one thing but I don't think that they'll be able to bring a better memory controller nor do I think that they'll be able to do 32nm in time for a 2011 release

The 4 instruction pipelines shown in each core are not cores, but part of a core. The diagram contains a scheme of one Bulldozer module, which contains two integer cores.

I think some of you are confused. AMD's Bulldozer is going up against Intel's Sandy Bridge not Nehalem lol. Bulldozer should easily smoke Nehalem out of the water. Phenom II was Nehalem's challenge. It's just common sense; AMD would be digging themselves in a hole if Bulldozer was meant to compete against the already aging Nehalem. Then what about Sandy Bridge? We would have a Phenom vs. Nehalem scenario all over again. AMD isn’t kidding when they said they plan on Bulldozing the competition.

I believe that AMD has already stated that Bulldozer will be initially implemented on GloFo's 28nm HKMG SOI process now undergoing qualification. It was my understanding that GloFo dropped 32nm, going straight to 28nm.
