Its mission statement: 'To make computers more stable, more useful, faster, and easier to use.' Outertech's lead products include Cacheman (short for Cache Manager), an award-winning Microsoft Windows performance optimization program initially developed in 1996 as the very first Windows optimization software ever. Incorporated in 1999, Outertech is a software development company based in Coburg, Germany. System Requirements: Windows 10, 8.1, 8, 7, Vista or XP Journalists and bloggers may request a reviewer's license code by contacting A free test version of Cacheman can be downloaded at: Users can manually try this optimization by right clicking the name of the application in the Cacheman user interface and selecting Set Core Affinity (sticky) | Core 1-8 from the menu.Ĭacheman starts at USD 28.95.

Outertech expects a fix from Microsoft on this issue and has decided against an automatic Cacheman optimization of this particular issue at this time. Switching program threads from one CCX group to another can cause performance degradation on an otherwise very fast processor. Windows 10 appears to not be aware that the Ryzen processor consists of two individual CPU core groups. This will work well only with applications that do not make full use of all 16 CPU cores, particularly computer games. Outertech has discovered that tying some Windows applications to the first Ryzen 7 CPU CCX group (4 physical + 4 virtual processor cores) can increase the performance by a significant factor, as thread switching between two CCX groups is avoided. A range of computer performance profiles is available including gaming, graphics workstation, digital audio recording, notebook, and server. In addition to the already build-in Intel Core processor optimization, Cacheman 10.10 updates the optimization profiles for AMD Ryzen 7 1700, 1700X, 1800X and Ryzen 5 1400, 1500X, 1600, 1600X processors.

Communication between cores that sit on separate CCX groups is significantly slower (by the factor of 2 and more).Ĭacheman (short for Cache manager) auto-optimizes the Windows sub-systems including cache and memory in order to improve responsiveness, privacy, and security.

Within a CCX group CPU cores can communicate very quickly with each other. The speed of the crossbar is linked to the speed of the system memory. The two groups are interconnected with with a 256-bit wide bi-directional crossbar. The physical processor cores are placed on the CPU die in two groups of 4 cores each, the so called CCX (CPU Complex). COBURG, GERMANY, Ap/24-7PressRelease/ - The AMD Ryzen 7 processors consist of 16 CPU cores, 8 physical and 8 virtual (emulated) cores.
