Outertech Cacheman 10.10 adds AMD Ryzen Processor Optimization

Outertech has released Cacheman 10.10, a Windows performance enhancement software that uses one-click optimization in order to improve responsiveness, privacy, and the security of a PC. The new Cacheman version introduces support for the recently released AMD Ryzen 7 1700, 1700X, 1800X and Ryzen 5 1400, 1500X, 1600, 1600X processors. A free test version is available from the Outertech website.

The AMD Ryzen 7 processors consist of 16 CPU cores – 8 physical and 8 virtual (emulated) cores. The physical processor cores are placed on the CPU die in two groups of 4 cores each, the so called CCX (CPU Complex). The two groups are interconnected with a 256-bit wide bi-directional crossbar. The speed of the crossbar is linked to the speed of the system memory. Within a CCX group, CPU cores can communicate very quickly with each other. Communication between cores that sit on separate CCX groups is significantly slower (by the factor of 2 and more).

Cacheman (short for Cache manager) auto-optimizes the Windows sub-systems including cache and memory in order to improve responsiveness, privacy, and security. In addition to the already built-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. A range of computer performance profiles is available including gaming, graphics workstation, digital audio recording, notebook, and server.

After a discovery made in the testing lab Outertech recommends an additional manual optimization that can be performed within the Cacheman user interface.

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. This will work well only with applications that do not make full use of all 16 CPU cores, particularly computer games. Windows 10 appears to not be aware that the Ryzen processor consists of two individual CPU core groups. Switching program threads from one CCX group to another can cause performance degradation on an otherwise very fast processor. Outertech expects a fix from Microsoft on this issue and has decided against an automatic Cacheman optimization of this particular issue at this time. 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. Cacheman will remember this tweak and apply it automatically each time the game is started.

Cacheman starts at USD 28.95.
