No, they just wanted to show the core architecture so they just show one 'block' of the core
Its not a risk, they MUST create new architecture to compete with Intel CPUs. Their desktop its pretty good but their mobile segment are pretty poor as compared to Intel counterparts, both in performance and battery life

The Bulldozer architecture is pretty radical, as it is not a 'true' dual core as it share fetch and decode blocks, FPU and L2 caches and claiming its '80% performance of true dual core' to reduce thermal and power envelope. I hope there is more to that.

Bulldozer is one risky architecture for AMD. At the same time AMD is making its first 32nm CPU on an unproven, new and risky process and the company is making a completely new core, something that it hasn't done for years. When you do both of these things at once, you kind of have a recipe for potential disaster. AMD might get lucky this time and we're hoping that it will have more luck than with its transition to 65nm and the K10 native quad-core. As you probably remember, that transition was anything but smooth.

AMD 9 Series Chipsets detailed

AMD 9 series chipsets (990FX, 990X, 970) detailed with new logos;

New on the agenda of the next-generation Fusion processors, AMD months working on for about five years, based on the design of next-generation microprocessor, code-named Bulldozer CPUs will be marketed. . Four, six and eight-core, AMD will use a different processor models, the new 9-series chipsets at the same time announce. Bulldozer-based processors with AMD's Socket AM3 + form is going to change the socket for the new processors will transition to the users also need to get a new motherboard. However, this followed a different strategy, AMD continued to support retroactive, current product line in the form of the Athlon Socket AM3 Phenom II and II + motherboards Socket AM3 processors to work with models in 9 series chipset will enable. So Bulldozer-based next-generation processors, 7, or 8-series chipset motherboards will not work with all existing form, but Socket AM3 processors to work Bulldozer family prepared for the new motherboards.

Rumour: AMD FX-series (Bulldozer) releasing June 11th
Reported by Sub on Thursday, March 17 2011 3:09 pm

Five years in the making, AMD's Bulldozer has gone through a slew of changes in schedule. According to the last report, Bulldozer's shipping date was suggested as June 20th. Now, DonanimHaber is introducing a new date - June 11th. AMD's 9-series motherboards will release in May, presumably during Computex 2011 time. Around this time, AMD's FX series is expected to be officially announced and dated.

AMD's FX "Bulldozer" CPU Clock Speeds Revealed



While AMD is rather cautious in its official statements in regards to anything related to the upcoming CPU offerings based on the next-generation Bulldozer architecture, unofficial sources leak more and more information. This is not a surprise, as the launch is drawing near. Now a Chinese website published excerpts from datasheets explaining the technical specifications of various Bulldozer samples. These are not the usual engineering samples we are talking about here (those are ticking at 1.8 and 2.6GHz), but samples of actual products that are going to be launched on June 7, 2011 in Taipei, Taiwan.
