Advanced Micro Devices may further delay release of its highly-anticipated FX-series microprocessors code-named Zambezi that are based on the Bulldozer micro-architecture, according to slides published by a web-site. Apparently, AMD may only launch its next-generation chips for desktops only in September, if the slides are genuine.

Two images, which resemble those from AMD's roadmaps, indicate that the FX-series "Zambezi" central processing units (CPUs) will only be production ready in August and will be launched on Septembers. The images, which were published by web-site, also point to new model numbers for the chips: FX-8150, FX-8100, FX-6100 and FX-4100, which may indicate that the company intends to alter previously set specifications of the chips.

Earlier it was believed that AMD would launch its FX-series of chips in June, 2011, at the E3 trade-show. It was also reported that the highest-performing eight-core offering would cost $320, which is in line with the top-of-the-range Core i-series "Sandy Bridge" CPU.

The potential delay of Zambezi to September will be another postponement in a long row of Bulldozer set-backs. Initially, the company wanted to make Bulldozer micro-architecture powered chips using 45nm SOI process technology, but it was not economically feasible. As a result, AMD had to stick to 32nm SOI fabrication process, which turned out to be problematic for its partner Globalfoundries. The latter even had to reconsider its agreements with AMD under which the latter pays only for working dies, not wafers that contain potentially faulty chips.

Although sales of high-performance microprocessors do not peak in Summer, production ramp usually takes time and therefore launch in September means that the company will only be able to ship "Bulldozers" in high volume sometimes late in 2011 or even in 2012. This will slowdown revenue growth of the Sunnyvale, California-based chip designer.

AMD Orochi design is the company's next-generation processor for high-end desktop (Zambezi) and server (Valencia) markets. The chip will feature up to 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 8MB 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.

AMD did not comment on the news-story.

If this is true, AMD should start thinking about not producing these processors at all. They wont be competitive against Ivy bridge either in terms of power or performance.

That puts AMD on the path of VIA - archaic processors for which there is no demand.

ZOMG, because even if AMD is competitive at every price point under $300 now with Phenom/Athlon II, they should just give up if they can't beat Sandy Bridge in Super Pi by a solid margin.

PS: Intel had a heck of a time with 32nm, how long did it take them to get a quad core to market? They sat on i3 dual cores forever, and the purpose of the 980x was to test making a larger chip, it cost $1000 because they couldn't possibly have made it in volume, so they deterred people with the high price and used the margin to recoup some R&D money.

Every node below 45nm is exponentially more challenging, they're hitting some hard limitations, I predict Ivy Bridge will be later than they're claiming, maybe 2013 or even 2014.

Fanboyz buy Intel until kingdom come.. is this somehow tragic??

If you don't buy it nobody will, I'm sure. ROFL

Frequent redesigns compensate for bad engineering.
You are not an engineer. Only tragic for fanboyz.
Hopefully this design lasts 10 years or more.
New is not always better, my friend.

Intel hasn't redesigned any of their CPU designs from ground up since Netburst. What's your point? Core, Nehalem and Sandy Bridge are based off one another and their roots can be traced back to Pentium III which itself can be traced back to Pentium Pro. AMD's last ground up redesign was with AMD K8.

Many fanboys also fail to realize, they need AMD in the market else Intel would be free to dictate CPU prices and make a lot of the CPUs out of reach for most consumers. It's bad for consumers if AMD falls. They also fail to realize that without AMD, most people would still be stuck in the 32-bit era. AMD was the ones who pushed for virtualization and 64-bit to the x86.

Do also note that the performance market (which most PC enthusiasts are situated) is a very small market compared to the low-end market which is huge. AMD's thriving in this market. The days where you have the most powerful CPU is nearing its end, now it's all about power efficiency and enough horsepower to do your tasks in a timely manner. Lastly, it's also about who has a better IGP since a lot of tasks these days emphasizes on having an excellent graphical subsystems.

Bulldozer is truly a revolutionary design. Never did AMD nor Intel used shared FPU units and so many architecture improvements. In fact, Bulldozer will be another lesson AMD teaches Intel; after they've taught them what good branch prediction and ondie cache does in the K6 ~ K6-3+ times, what a good FPU does in K7, what an IMC does in the K8 times .

And Intel was ALWAYS second to the table on each of these chapters. Sure they were better .. being late / having more time to design , having 100 times more money and having a REAL LIFE EXAMPLE in AMD's designs ensured the fact that Intel version of the improvements stated above were impressive.

Sure .. maybe Bulldozer won;t be faster then Ivy bridge but it is not supposed to. As Ivy Bridge is an improvement on SB , so will Bulldozer's next iteration bring more performance to the table.

IMHO AMD is delaying this , is because they have to give 100% of the production to the server makers.

Looks like that it is faked offer. That is why
AMD originally wanted to launch Bulldozer at Computex but performance issues with its B0 and B1 stepping chips pushed back the launch. Now they are looking at a late July launch with B2 silicon, but performance today is a big unknown. Apparently the performance of B1 stepping silicon doesn't look too good.
