About 1.7 seconds separates the XPG Spectrix S40G from its XPG sibling - the SX8200 Pro. This may be important to some, but we don't think it is much of a factor when you consider what the S40G is really about.
PCMark 8 accurately represents real-world performance and confirms what we've seen to this point. The Spectrix S40G while plenty fast, and even the fastest in certain scenarios, is more of a lover than a fighter. We don't find this surprising at all. New controller brands tend to have a learning curve and Realtek is no exception.
