AMD has again inadvertently released a document containing secret information regarding product announcements. Last week the company issued a press release revealing AMD Opteron 246 processor launch date as well as AMD Athlon 64 logotype presentation. Today News.com reported that Sunnyvale, California-based chipmaker has sent them a paper saying that the long-awaited AMD Athlon 64 microprocessor will be formally announced on the 22^nd of September.

Earlier we reported that the most important announcement for AMD this year will take place at the Moscone Convention Center in San Francisco on the 30^th of September. However, by releasing a kind of official statement, Advanced Micro Devices has denied the rumour.

Also on the 22^nd of September, 2003, AMD is expected to unveil its Athlon 64-M processor for mobile computers, according to the report. Since there will be not a lot of AMD Athlon 64 processors this year and all of them will be positioned against higher-end Intel Pentium 4 products, I do not expect the company to deliver loads of its mobile 64-bit CPUs in 2003.

The initial AMD Athlon 64 processors for desktops will have 3100+ and 3400+ performance ratings and will be equipped with 1MB of L2 cache. More models with smaller L2 cache will be available later. No information about pricing and performance of mobile AMD64 processors is available at present.
