Dual-core Xeons arrive
Although Intel has yet to formally announce the processor, Dell is already pushing servers and workstations based on a new "Paxville" dual-core Xeon. Clocked at 2.8GHz, the chip features 2MB of L2 cache per core and apparently outperforms existing single-core Xeons by a significant margin.
The dual-core 2.8GHz Xeon outperforms the single-core equivalent running at 3.6GHz in several server speed tests that can take advantage of dual-core chips' better ability to perform multiple jobs at the same time. Microsoft Exchange runs 18 percent faster; database software, 37 percent; and Java applications, 43 percent, Dell said.
Intel hadn't intended to release dual-core Xeon processors until next year, but the introduction of AMD's dual-core Opteron family may have forced its hand. AMD isn't letting up, either. According to
The Inquirer, Opteron 280 and 880 processors are now available, pushing dual-core Opterons up to 2.4GHz.
