Ooops... here it is: (be happy with the current Banias aka Pentium M)
Intel's 'Prescott' has no performance advantage over AMD

SAN FRANCISCO--Intel Corp.'s new "Prescott" microprocessor isn't setting the world on fire and appears to have no performance advantage over rival chips from Advanced Micro Devices Inc., according to a new report from American Technology Research Inc. today (February 3, 2004).
As reported, Intel on Monday officially rolled out its long-awaited, 90-nm "Prescott" line of microprocessors, with plans to extend the chip to 4-GHz by year's end. "Prescott" is a 90-nm version of Intel's Pentium 4 processor line (see Februray 1 story).
"Early performance evaluations suggest that on a full 1-GHz higher clock rate, the 90-nm Prescott has not appreciably widened the performance gap over Athlon XP, AMD's 32-bit 130-nm (processor)," said Rick Whittington, an analyst with American Technology Research, a market research house.
"Despite the 31-stage pipeline, in which prospective operations are predicted or anticipated so as to improve overall system performance, Prescott is coming up with indiscernible performance gains vs. Athlon XP," Whittington said in the report.
"AMD will soon transition to its 90-nm process suggesting that eventual process-derived performance gains by Intel could be matched by AMD. Furthermore, Athlon 64 on 130-nm runs common 32-bit desktop applications noticeably better than Prescott but will soon have 64-bit Windows beta applications to demonstrably widen that gap," he said.
There are some other issues. "Prescott was, according to our memory, to be introduced at 4-Ghz and be readily scalable to 5-GHz better on a 90-nm process, which was to generate far less heat than that of today," he said in the report. "At such high clock rates, Hyperthreading was to kick in with a vengeance," he said.
"However, the same issues which have sidelined Dothan (90nm Centrino) until April-May this year, from an initial October-November 2003 launch date are keeping Intel from cranking up the clock on Prescott," he said. "At 3.2-GHz, Prescott generates 103 watts which is thought the acceptable maximum for today's desktops and beyond which entirely new motherboards and cooling apparatus is required," he said.
"Early looks at the present Dothan re-design of a very large chip, given its 2.5Gigabits of cache memory, suggests a very slow clocking for it and effectively no performance gain versus 130nm Centrino," according to the report.
Intel does have some advantages with Prescott. "The one area in which Prescott shines, owing to its 31-stage pipeline, is media creation which fits into Intel's recent strategy of casting the company's desktop processors into the burgeoning home or consumer entertainment market," he said. "For more classical desktop applications, the 31-stage pipeline is apparently sufficiently error prone to require frequent pipeline flushing which materially slows performance," he said.
