POWER8 Memory Buffer
The IBM® POWER8® Memory Buffer supports multiple system configurations. It uses a high-speed differential interface to communicate with a processor chip using a memory-agnostic protocol. This enables the memory buffer to support several DDR memory technologies without the need for a processor upgrade. The maintenance and calibration functions for the memory controller and associated memory interface are initiated and contained within the memory buffer chip. The Memory Buffer also contains a 16 MB on-board cache to support prefetching and to improve system performance.

POWER8 Processor
The IBM® POWER8® Processor is a superscalar symmetric multiprocessor designed for use in servers and large-cluster systems. Based on IBM® Power Architecture®, it provides even more performance than its predecessors while increasing the memory bandwidth and I/O speed. The chip uses a 22 nm silicon-on-insulator (SOI) fabrication process with 15 metal layers. The POWER8 processor provides significant performance at the thread, core, and system levels. It is optimized for efficiency, enables autonomic system optimization, and provides excellent big data analytics capability
In the single-chip module (SCM) configuration, the processor can have up to 12 cores on a single chip. Each core has eight threads using simultaneous multithreading (SMT). The SMT is dynamically tunable, so that each core can have one, two, four, or eight threads.

POWER8 Memory Buffer
The IBM® POWER8® Memory Buffer supports multiple system configurations. It uses a high-speed differential interface to communicate with a processor chip using a memory-agnostic protocol. This enables the memory buffer to support several DDR memory technologies without the need for a processor upgrade. The maintenance and calibration functions for the memory controller and associated memory interface are initiated and contained within the memory buffer chip. The Memory Buffer also contains a 16 MB on-board cache to support prefetching and to improve system performance.

Coherent Accelerator Processor Interface (CAPI)
The Coherent Accelerator Processor Interface (CAPI) eliminates the complexity and overhead of an I/O subsystem. It enables a custom accelerator to operate as part of the coherent fabric of a POWER8 chip or a POWER9 chip. CAPI provides a high-performance solution for the implementation of customer-specific, computation-heavy algorithms on a field-programmable gate array (FPGA).
