Re: Memory Upgrade Dell 4550 Tower
The Banias core isn't a renamed Tualatin, it shares the P6 microarchitecture but it's heavily improved: new prediction branch, SSE2 instructions, segmented cache which can be powered off, a real SpeedStep: all things the Mobile P3 doesn't have.
The Mobile P4 couldn't live for long either: early Prescott based samples draw and heated too much for a notebook chassis, no further improvement was expected from the Northwood core and a low consumption version for the then promising subnotebook market was unfeaseable, leaving the path to the Transmeta Crusoe and Via C3. IMHO Pentium-M was necessary.
