1 GHz Pismo the Fastest G3 ‘Book Ever

Charles W Moore - 2008.12.15

Once upon a time, CPU upgrade vendor PowerLogix offered a 1 GHz G3 CPU upgrade for the Pismo PowerBook based on the IBM PowerPC 750GX CPU, doubling the clock speed of the fastest stock Pismo – and with a full megabyte of Level 2 (L2) cache also running at 1 GHz.

PowerPC 750 G3 CPUThe low-power IBM PowerPC 750GX is of the same CPU family as the 750FX chip that PowerLogix had previously used for Pismo upgrades, a CPU that had also powered the last generations of G3 iBooks running at several different clock speeds. However, the GX had twice the L2 cache of the FX and was available in faster clock speeds. (FX based 900 MHz upgrades were available from PowerLogix when this article was first published in 2004.)
