AMD Company today officially described about its servers plans, which got significant changes and now included processors with six and twelve core, which will appear in 2009 and 2010. Furthermore, AMD reported also about the promising server platform maranello, developed specially for processors with the increased number of system buses hyperTransport 3.0.
45 nm four core processor (shanghai) will be released as it was planned earlier, in the second-half of the present year. Besides the new production technology , which indicates increase in the clock frequencies and reduction in the heat emission, these CPU will introduce the support of system bus hyperTransport 3.0, utilized for inter-processor connections. In addition to this, new production technology will allow to increase the L3 cache to 6 Mbytes . AMD mentions, that Shanghai will prove to be approximately up to 20% faster than Barcelona with identical clock frequency. This advantage will be ensured by micro-architectural improvements ( as 45 nm ) .
In the second place, AMD officially confirmed plans about the six-core processor istanbul, which will be released in the second-half of 2009 and witch will preserve compatibility with that existing socket F1 (1207) . This CPU will be oriented for systems with two and four sockets.
Then, in first half of 2010 AMD plan to present the sequential server platform, which uses new Socket g34. The Basic reason for passage to the new processor socket is DDR3 support and four system buses hyperTransport 3.0 in each CPU (instead of three, utilized at present). The new platform maranello will include the server chipset AMD RD890. For the Socket g34 AMD will release a special processors server : six-core Sao paolo 6 mega-byte L3 cache and Magny with 12 Mbytes. Both CPU will be released on 45 nm technological process.
Note in the middle of 2010 AMD plan to use 45 nm technological process, while intel will pass to the 32 nm technology in the second-half of 2009.
