[ 1 ] IBM stated that it is the world's fastest microprocessor by clock rate at 5.2 GHz, [ 2 ] with a 10% increased performance per core and 30% for the ...
In July 2017, with another generation of products, the official family was changed to IBM Z from IBM z Systems; the IBM Z family now includes the newest model, the IBM z17, as well as the z16, z15, z14, and z13 (released under the IBM z Systems/IBM System z names), the IBM zEnterprise models (in common use the zEC12 and z196), the IBM System ...
IBM introduced its first z/Architecture-based system, the z900, in late 2000. [1] Later z/Architecture systems include the IBM z800, z990, z890, System z9, System z10, zEnterprise 196, zEnterprise 114, zEC12, zBC12, z13, z14, z15 and z16.
A single-frame IBM z15 mainframe. Larger capacity models can have up to four total frames. This model has blue accents, as compared with the LinuxONE III model with orange highlights. A pair of IBM mainframes. On the left is the IBM z Systems z13. On the right is the IBM LinuxONE Rockhopper. An IBM System z9 mainframe
The cache (e.g. level 3) is doubled from the previous generation z14, while the "L4 cache increased from 672MB to 960MB, or +43%" with the new add-on chip system controller (SC) SCM. Both it and all levels of cache in the main processor from level 1 use eDRAM, instead of the traditionally used SRAM. "A five-CPC drawer system has 4800 MB (5 x ...
The IBM System z Application Assist Processor (zAAP), previously known as the zSeries Application Assist Processor, is a mainframe processor introduced by IBM in 2004. zAAP engines [1] are dedicated to running specific Java and XML workloads under z/OS, accelerating performance. zAAPs are available for zSeries 990 and 890 servers and later zSeries and zEnterprise models.
