There was an earlier HBM vs GDDR5 comparison that was similar to this.
The change seems to be that this says HBM2, and the bandwidth and power gains are more modest versus GDDR5. Perhaps this is relative to the most recent variations of both. The density section starts a 16Gb per stack rather than 8.
Other than that, I am curious what the generational change would be between the generations. There was an originally projected higher ceiling for the data rate past Gen1, which this doesn't seem to promise.
