It appears that AMD will launch two Barcelona processors in September, the Opteron 2348 and 2350:
The Opteron 2348 and 2350 will have core frequencies of 1.9GHz and 2.0GHz and will be priced at US$320 and US$390 in 1000-unit tray quantities, respectively. In October, AMD will launch the 2.2GHz Opteron 2354 with 95W TDP and a price of US$610 in 1000-unit tray quantities, however this processor should actually appear in the channel later this month, noted the sources.
The Opteron 2300 series will include Opteron 2340, 2350, 2352, 2354, 2356, 2358 and 2360. Models at frequencies higher than 2.0GHz are expected to launch in the fourth quarter, according to an earlier announcement by AMD.
AMD also has plans to introduce the 8-way Opteron 8300 series which will include Opteron 8348, 8350, 8352, 8354 and 8356 models, added the sources.
