Analyzing Creator Mode and Game Mode
Way back on page 3, this review explained that AMD was promoting two modes: Creator Mode with all cores enabled and a uniform memory access (UMA) architecture, and Game Mode that disabled one of the dies and adjusted to a non-uniform memory architecture (NUMA). The idea was that in Creator Mode you had all the threads and bandwidth, while Game Mode focused on compatibility with games that freaked out if you had too many cores, but also memory and core-to-core latency by pinning data as close to the core as possible, and keeping related threads all within the same Zeppelin die. Both methods have their positives and negatives, and although they can be enabled through a button press in Ryzen Master and a reboot, most users who care enough about these settings are likely to set it and forget it. (And then notice that if the BIOS resets, so does the settings…)
*This page has been edited on 8/17, due to a misinterpretation in the implementation of Game Mode. This original review has been updated to reflect this. We have written a secondary mini-article with fresh testing on the effects of Game Mode.
