Here is a good explanation
Unique Events (New) - counts the number of events with unique Event properties (Event Category, Event Actionand Event Label) that occur within a single session
Unique Dimension Combinations (Legacy "Unique Events"): counts the number of unique dimension combination values, which can apply to any dimensions included in a report. What that means is that if you have dimensions A, B, and C in a report, and include this metric, Google Analytics will count the unique number of times the same combination of values occurs for each row of dimension values (A+B+C) in the report
