POWER8, 64-bit, hex or twelve core, 8 way SMT/core, 5.0 GHz, follows the Power ISA 2.07. Introduced in 2014. POWER9, 64-bit, PowerNV 24 cores of 4 way SMT/core, PowerVM 12 cores of 8 way SMT/core, follows the Power ISA 3.0. Introduced in 2016. Power10, 64-bit, 15 SMT8 or 30 SMT4 cores, will follow the Power ISA 3.1. Introduced in 2021.
The PowerPC 970, PowerPC 970FX, and PowerPC 970MP are 64-bit PowerPC CPUs from IBM introduced in 2002. Apple branded the 970 as PowerPC G5 for its Power Mac G5 . Having created the PowerPC architecture in the early 1990s via the AIM alliance , the 970 family was created through a further collaboration between IBM and Apple .
The northbridge was replaced by the system agent introduced by the Intel Sandy Bridge microarchitecture in 2011, which essentially handles all previous Northbridge functions. [10] Intel's Sandy Bridge processors feature full integration of northbridge functions onto the CPU chip, along with processor cores, memory controller, high speed PCI ...
The 970 is a 64-bit processor derived from the POWER4 server processor. To create it, the POWER4 core was modified to be backward-compatible with 32-bit PowerPC processors, and a vector unit (similar to the AltiVec extensions in Motorola's 74xx series) was added.

ICH - 82801AA. The first version of the ICH was released in June 1999 along with the Intel 810 northbridge.While its predecessor, the PIIX, was connected to the northbridge through an internal PCI bus with a bandwidth of 133 MB/s, the ICH used a proprietary interface (called by Intel Hub Interface) that linked it to the northbridge through an 8-bit wide, 266 MB/s bus.

An operating system running on PowerPC 615 could either choose to execute 32-bit or 64-bit PowerPC instructions, 32-bit x86 instructions or a mix of three. Mixing instructions would involve a context switch in the CPU with a small overhead. The only operating systems that supported the 615 were Minix and a special development version of OS/2. [38]
