At the forthcoming CeBIT trade-show in Hannover, Germany, Advanced Micro Devices plans to demonstrate and announce its new microprocessors that will succeed the company's Phenom II central processing units (CPUs). Based on the program of CeBIT show, the company will show off the desktop versions of code-named Bulldozer chips.

"The U.S.-based CPU and chip maker AMD will present at CeBIT 2011 processors, which performance exceeds the current top models of the Phenom-II series by 50%," the of official description of a CeBIT "theme and event" reads.

In case AMD formally introduces its desktop processors based on Bulldozer micro-architecture code-named Zambezi at CeBIT, it will not be a big surprise as the company already used the show for formal introduction of important products and technologies in the previous years. The big question, however, is whether the company will initiate a review program for the new chips shortly after the show, will unveil official performance levels of the chip or will let select journalists to "independently" benchmark the new CPUs on site, a more than controversial move.

The first Zambezi microprocessors to be launched are expected to be eight-core products with 95W and 125W thermal design power as well as 8MB L3 cache. Later in the second quarter of 2011 AMD, according to sources with knowledge of the company's roadmap, will release six-core chips with 8MB L3 cache and four-core products with 4MB cache. All of the processors will feature TurboCore 2.0 technology, dual-channel DDR3 memory controller with up to 1866MHz memory support and will be compatible with AM3+ mainboards.

Eight-core Zambezi/Orochi features four dual-core Bulldozer modules, each of which is believed to have 2MB of shared level-two cache, that will share 8MB L3 cache. In total, the whole chip will pack in whopping 16MB of cache.

AMD Orochi design is the company's next-generation processor for high-end desktop (Zambezi) and server (Valencia) markets. The chip will feature eight processing engines, but since it is based on Bulldozer micro-architecture, those cores will be packed into four modules. Every module which will have two independent integer cores (that will share fetch, decode and L2 functionality) with dedicated schedulers, one "Flex FP" floating point unit with two 128-bit FMAC pipes with one FP scheduler. The chip will have shared L3 cache, new dual-channel DDR3 memory controller and will use HyperTransport 3.1 bus. The Zambezi chips will use new AM3+ form-factor and will require brand new platforms.

The code-named Zambezi processors based on Bulldozer micro-architecture with four, six or eight cores will belong to FX-series and will be sold under AMD Vision Black and AMD Vision Ultimate labels.

There is no doubt 8-core Bulldozer will beat any Sandy Bridge CPU. If not, BD would be a dismal technical failure.

What I am looking forward to is the relative performance of 6-core and 4-core versions.

Forget Sandy Bridge. If the leaked reports are true then AMD's 8 core Bulldozer will absolutely demolish even Intel's 980X (6 core Gulftown) . The report shows Bulldozer is twice as fast as 980X.
Here is the leaked report

the point of the comparison is that a 8 core BD will be similarly sized to a 6 core SB, and can therefore be similarly priced.
the '2 cores with a shared front end en FP unit' design saves a lot of transistors.

while i dont think BD's single threaded performance will be quit a fast as SB it will be fast enough (face it, almost all single threaded programmes are either old, or CPU performance isn't a critical factor) you get a lot more cores for your buck.

that's why i never state anything i believe regarding BD performance as fact, unlike you did in the above response.

really?!? I was imploring to to what the thread starter referred to as dismal technical failure which by the way is far more witty than the garbage on response #3

if its fact that you want here are some:

as of this writing, BD is still a vaporware. It may look good on paper and in theory. But as long as there's no actual product in the market (or even an engineering sample being benchmarked anywhere), BD is just a bunch of mumbo-jumbo for AMD's PR.

Based on previous articles on AMD simulations Bulldozer 8 cores are 50% faster then AMD's current 6 cores. Which means each core is 11% faster then previous gen.

http://www.xbitlabs.com/n...ozer_Microprocessors.html

Considering that AMD's current server chips aren't competitive with Old Intel Core i Offerings, These shouldn't be competitive with new SB processors which are around 10% faster then original Core i. And when Intel releases 22nm versions very soon, AMD will be very behind.

intel isnt releasing 22nm soon, that still a year away in any volume.
also AMD will be able to provide a lot more cores for the same amount of money.
specially in the server market that will be a large advantage.

Early test show that Zambezi will be very similar to Intel 980 x perfomance,but I think that Liano be more intereting.

Based on the news we have rumors that
1) AMD will drop the names like phenom , athlon, so on.
2) FX lines will be brought back.

3) Top AMD employees all left AMD. (not a rumor)
4) High Turbo's and clock speeds will be available on Bulldozer.

From those we can try to guess at the performance of the processor better then "leaked reports" that might be fake.

Most likely the FX is being brought back to either replace black edition, to indicate which is most overclocking friendly, or for Highest clock / High Turboing models.

If Bulldozer was going to be a huge success you'd leave AMD in the year after it comes out, not before.
