UMA and NUMA Configuration Testing

We've tested both Threadripper CPUs at the default Ryzen Master setting of Creator Mode, which applies the distributed mode/Uniform Memory Access (UMA). This should benefit multi-threaded tasks, and AMD has found that there’s a net gain in this mode for non-gaming applications. However, to save complicating our main graphs, we’ve carried out some additional testing in both pure Game Mode (enables local mode/Non-Uniform Memory Access (NUMA) as well as Legacy Mode, which disables cores and threads) and also in Game Mode with Legacy Mode disabled, thus keeping the maximum core and thread count.

We only had time to do this for the Ryzen Threadripper 1950X, but hopefully it gives a good indication of what performance boosts or cuts you can expect in the various modes across games and non-gaming applications. All additional testing was carried out with the CPU overclocked to 3.85GHz, so to see the actual gains from applying the different modes, simply compare the additional results with the standard 1950X overclocked result.
