A report by IT analyst Clabby Analytics declared that Intel's Itanium is the leader in the 64-bit processor market, because of its superior functionality and Intel's roadmap for the market. AMD and Sun beg to differ, and suggest that, when it comes down to the wire, Itanium doesn't look so good at all.
In the report, titled "Performance-on-the-Die: The 64-bit Server Report," analyst Joe Clabby describes the comparative differences between AMD Opteron, IBM POWER, Intel Itanium, and Sun UltraSPARC 64-bit architectures, and analyses the market positioning of each product offering.
"Our research shows that there are significant differences between the 64- bit microprocessors offered by AMD, IBM, Intel, and Sun," said Clabby. "IT buyers need to understand these differences in order to make informed decisions on which platforms to choose to meet their enterprise's strategic computing needs."
The report, written after three months of interviews with vendors, makes a strong case for Intel's Itanium as the best choice among 64-bit architectures. Among the reasons for that choice, according to Clabby, is the fact that Itanium can run both Windows .NET and
Unix/Linux J2EE environments, and that Intel has solid parallelization and multi-core plans for Itanium.
Clabby cites IBM's pSeries as the strategic platform of choice for 64-bit Linux and Unix environments, and notes that IBM's Power processor is already capable of dual core and chip-level threading. Sun has a roadmap to bring multi-threading and multi-core capabilities to market, says the report, but Clabby cautions buyers that sales volumes of Sun's UltraSparc 64-bit processor are declining.
