Big MISS for HP's Copper and SOI PA-8700 processor. HP introduced this today, made with a .18 micron process, and it only runs at 750 MHz - slower than Intel's existing Itanium processor - made without copper and without SOI - on a standard .18 micron process (800 MHz). HP jumped from Intel to IBM as a foundry source for improved speed with IBM's copper and SOI process - and came up short big time - (they expected 1 GHz+ CPUs as I recall). Monica Good point Monica! This is the vaulted SOI process that is going to save AMD! You're right too, it's slower than Itanium and Xeon as well. It does have a very large on-die cache at 2.25Meg but so does Xeon and almost exactly the same size while Xeon runs at up to 900MHz on an Aluminum .18u process. SOI looks like a yawner to me! EP

SOI taking Motorola from 400MHZ to 1600MHZ in barely a year: The 64 bit G5 uses 26w at 1.4GHZ - Itanic comparisons invited. High clock speeds also mean high power dissipation, but Motorola has nicely countered it by fabbing the G5 using silicon-on-insulator technology, leading to a power dissipation of 26W at 1.4GHz, our source tells us. By comparison, the 7450 draws 14W at 533MHz. Our source had no word on what process Motorola will use for the part, but we reckon 0.13 micron with copper interconnects. The transistor count will be 58 million gates. That's said to be twice the 7450's transistor count, which makes us wonder what Motorola will do with the extra gates. The longer pipeline and additional instruction units will account for a lot of it, but we also wonder if the chip will feature a built-in memory manager, something Motorola has been talking about of late. Beyond far higher clock speeds, the G5 will be a full 64-bit chip, but will support 32-bit addressing at full speed. The part will also support multi-processor configurations. theregister.co.uk
