In power-deterministic mode, the CPU runs as fast as possible within a given TDP. There will be some performance variation from CPU to CPU, but overall this mode maximizes performance within a given power envelope. In performance deterministic mode, performance is identical across all servers, but TDP may vary from server to server based on the specific manufacturing quirks of the CPU in question.Overall, these two modes allow Epyc customers to choose whether they wish to emphasize constant performance and variable TDP, or to hold TDP constant and allow performance to vary. The specifics of which option is “better” depends on the workload in question.
As far Epyc’s overall performance in the market and Intel’s responses to it, there’s not a ton of data out there that we haven’t previously covered. AMD continues to win back some server customers and market share, but it’s not clear if the company will revamp its Epyc product families before the launch of 7nm chips next year. The company has done an excellent job building servers to field against Intel, but the natural conservatism of the server market and Intel’s determination to hold the space are likely to be challenges going forward. Still, Epyc is building momentum and winning customers — and it wasn’t even 18 months ago that this was far from a sure thing.
