If you are connected to 125 nodes, then for 200 TPS only the hashes already are 0.8 MBps:
125 * 32 * 200 = 800000 = 0.8 MBps
People often forget that.
Even if they can teleport the blocks and the transactions. The hashes alone are > 0.5 MBps.
At maximum hashes would only need to be
16 8 byte first bits, likely even less.
125 * 8 * 200 = 200000 = 0.2 MBps
