AMD has announced the next generation server platform processors codenamed as “Shanghai”. These server processors will run at speeds ranging from 2.3 GHz to 2.7 GHz. All the new processors will run at 75 watt TDP.
These chips are the 45 nm variants of the Barcelona range of processors. But they are not just a mere die shrink, they have some enhancements too. These processors will have a 6 MB L3 cache memory which is the major difference between the previous generation ones which has only 2 MB cache. AMD touts better virtualization performance by these new processors.
By going to 45 nm technology, not only can these chips run at a higher speed but also at a lower wattage and lower heat emission, both of which are vital for server systems.
The previous gen Barcelona had several issues ranging from poor clock speeds to initial TLB errors and poor availability. These all created a very bad review about those server processors and AMD will be hoping that these ones can compete very well with the Intel Harpertown processors.
