AMD's John Fruehe published a blog post with details about the company's upcoming server chips, you can read it over here.
In Q1 2010 we plan to introduce the “Maranello” platform, featuring the processor variant currently codenamed “Magny-Cours.” This is a new socket (G34) and the processor is expected to merge both the top end of the 2P market with the 4P/8P market, all conveniently in a single processor, the AMD Opteron 6000 Series processor. Core choices are expected to be 8 and 12 cores, with massive memory scalability through the 4 channels of DDR-3 memory per processor. By utilizing the same processor for both 2P and 4P designs, the AMD Opteron 6000 Series processor should enable several very interesting and flexible platforms with scalability of 16 cores through 48 cores. Clearly this processor is targeted at virtualization, HPC, database and business applications.
In Q2, we plan to introduce a new platform for web, cloud and infrastructure applications - the “San Marino” platform, featuring the 4-core and 6-core processor variants currently codenamed “Lisbon” in the C32 socket. With low core counts, these processors are expected to be a favored choice for applications that scale well up to 8-12 threads. The platform choices around “San Marino” are expected to help OEMs optimize their C32 systems for low power consumption and low cost. We believe these AMD Opteron 4000 Series processors will have the potential to help users achieve new levels of price/performance and performance/watt. When you walk through a data center and see rack after rack of servers, it’s clear that reducing the cost and power footprint of the “workhorse” servers can have a huge impact on the bottom line. Two channels of DDR-3 memory help provide the right level of scalability for these 1P/2P designs while contributing to low power consumption and cost..
