AMD had demonstrated the industry’s first
native quad-core x86 server processor,
achieving four x86 processing cores on a single die of silicon. At
the annual AMD Industry Analyst Forum, a server powered
by four upcoming Quad-Core AMD Opteron™ processors (codenamed Barcelona), manufactured
on 65nm silicon-on-insulator process technology, was shown utilizing all 16 cores.
By delivering a consistent thermal envelope while adding
two more processing cores, along with micro-architectural enhancements.
"Upgradeability from dual- to quad-core processors is expected to be as
straightforward as it was from single- to dual-core with AMD, with unchanged
thermal and electrical envelopes. The demonstration today was an example of
this. The reference server platform was seamlessly upgraded to quad-core by
replacing the server’s existing DDR2-based AMD Opteron processors with the new
Quad-Core AMD Opteron processors and updating the BIOS. The upcoming AMD Opteron
processors are based on AMD’s innovative Direct Connect Architecture, which
reduces bottlenecks found in legacy front-side bus x86 architectures and
includes AMD’s proven Integrated Memory Controller. These processors are
designed to enhance I/O throughput and CPU-to-CPU communication, and to deliver
increased performance with low power consumption and low memory
