In this article we present the new server architecture based on AMD's Bulldozer core class. We describe the 4200 series CPUs for 1 and 2-socket systems and 6200 series for 2 and 4-socket systems and a maximum of 64 cores.

Conclusions

The AMD Bulldozer CPUs in the server class embodiment, called Interlagos, are a drop-in replacement for the previous generation of Opteron CPUs, after updating the BIOS.

Using the appropriate compilers and libraries can make the most of features and also the new instructions unique to the architecture.

This task is much easier in the professional field where in general the code is optimized for the architecture on which the software will run.

In this case there is no doubt: as shown in the AMD Interlagos presentation, Bulldozer architecture provides higher performance, smaller footprint, higher density of the core and memory, lower power consumption and greater flexibility in relation to price.

On 14 November is the official launch of the new AMD Interlagos platforms. AMD has announced that not only these CPUs will be available immediately, but in fact many examples have already been delivered from time to important AMD partners. Bulldozer did not shine in the desktop, where he was greeted with a little disappointment, however, in the server, is received with very different expectations, positioning itself in a position of distinct advantage, at least for the moment, than the competition.
