I think you're off a zero, that would put VISA at only 167 tps. From iffy sources I found in a quick google, VISA averages 1700 tps and max capacity is significantly more. Rollups today can do around 2000 tx/sec. Their limit is block space, which will be multiplied by sharding (which in the current design, is more like RAID than actual sharding).
