bitcoin network: 24.264.816 GH/s vs 2.000 GH/s Cointerra terraminer IV

Hi all,
I have a question about the size of the present hashrate of the bitcoin network being some 24.000.000 GH/s (source: http://bitcoinwisdom.com/bitcoin/calculator)

If this hashrate would be delivered solely by a cointerra terraminer IV with a capacity of 2.000 GH/s this would mean that the bitcoinnetwork is
(24 million GH/s divided by 2.000 GH/s) 12.000 terraminers strong.

Is this calculation correct?

I had the impression you would need much more machines. Maybe a wrong feeling, but it seems so small.

and only a bit more than 6000 TerraMiner IV to complete a 51% attack?

But by the time IV comes online, the difficulty will be double.

With newer and more efficient ASICs coming out, we will then have a way larger network hashrate...
