System builders who received samples a week or two ahead of today’s worldwide launch say they aren’t ready to issue benchmarks just yet. Nevertheless, sources tell ChannelWeb that the processor AMD calls “the first native quad-core” is faster than they had anticipated. They say three key advances are testing out as advertised — a tri-level memory cache hierarchy with fully shared L3 cache for all four cores, a floating point unit with 2×128-bit loads/cycle, and independent power supplies for each of the processor’s four cores and to the memory controller. The last feature distinguishes AMD’s quad-core product from Intel’s, in that it’s possible to idle one, two or three CPU cores for a workload to better manage power consumption.
CMP Channel’s Test Center last week received an engineering sample server equipped with dual Barcelona CPUs. After putting it through its paces, Frank Ohlhorst reports, “Those who have waited for the arrival of AMD’s next generation CPU won’t be disappointed.”
As far as pricing, AMD is remaining tight-lipped about how it plans to scale its new quad-cores against Intel’s or its own dual-core chips. Partners in the know say Barcelona will be “competitively priced.” Market watchers say it will have to be, given Intel’s recent slashing of its own quad-core prices down to levels nearly in line with its Core 2 Duo products.
