AMD takes the wraps off its next-generation quad-core microarchitecture, code-named Barcelona. Rather than a complete overhaul, Barcelona integrates highly tweaked enhancements to the current Opteron architecture.
What is known is that Barcelona?as AMD has dubbed this first iteration?isn't so much a brand-new architecture as it is a highly refined, tweaked version of the existing AMD x86-64. Those tweaks are numerous and significant. It's probably fair to suggest that Barcelona is to the current Opterons as Intel's Core 2 is to the Pentium M?designed from the ground up, on a base of the old with a lot of new stuff rolled in.
The details of Barcelona discussed in this article were presented by Ben Sander, who led the performance modeling group for Barcelona. Sander's team cranked real-world application traces through iterations of the new processor?both simulated and real. Although he's uniquely positioned to discuss performance, Sander didn't really comment on performance yet. What he discussed instead were some of the enhancements built into Barcelona.
With these thoughts in mind, let's take a look at some of the shiny new features.
