Quite a bit of time has passed since the last AMD Bulldozer leaks made their way to the Web, but things seem to get on track once again and what better way to bring the FX-Series processors back into the limelight that with an impressive 4.63GHz overclock.The CPU that managed to achieve this feat seems to be an engineering sample of the FX-8130P and required about 1.5V in order to be stable enough to run the Super Pi benchmark at the above mentioned frequency.
From what we know at this point in time, the FX-8130P is supposed to be AMD's fastest desktop Bulldozer processor as it features eight processing core that are run at a base frequency of 3.8GHz.
Based on the load placed on its cores, the chip can increase its frequency up to 4.2GHz thanks to AMD's Turbo Core 2.0 technology.
In addition to the four Bulldozer modules, the FX-8130P also includes 8MB of Level 2 cache memory and 8MB of L3 cache as well as an integrated dual-channel memory controller that supports DDR3-1866 modules.
At this year's Computex fair, AMD has officially announced that the first Zambezi FX processors, based on the Bulldozer architecture, aren't expected to arrive until later this summer (August or September).
Before the news was made official, various reports suggested that AMD is having trouble with the performance of its Bulldozer architecture, as the first chip revisions functioned at lower than expected frequencies.
In order to fix these speed issues, AMD reportedly plans to build a new Bulldozer stepping, called B2, which should make the chips competitive with Intel's offerings.
The delay won't affect the Opteron 6200 processors based on the Interlagos architecture, which were demoed recently by AMD and pair together two CPU dies in the same packaging to form 12-core and 16-core Bulldozer CPUs for the server market. (OBRovsky Blog via Expreview)
