If you have Mapinfo 16 then you can easily convert raster data to point data.
Just open Mapinfo and go to Raster->Raster Operations->Export.
In the tool that comes up, select input Raster. In export to option, select Mapinfo TAB.
Select all other relevant option and run the operation. After sometimes you will get the desired result.
- Create a fishnet with the Vector grid tool in the Vector->Research Tools menu.
- Assign raster values to the polygons with the "Add grid values to shapes" tool in the Processing Toolbox (Simplified interface, GeoAlgorithms, Raster-vector, Raster->vector operations).

QGIS 3.4
There tool is a Raster pixels to points tool newly added in QGIS 3.4 (Oct./2018).
This tool works with astonishing speed. When I converted 11-megabyte single band raster to point layer (which end up with 6 million points), the process time was:
Raster pixels to points ............................................. | 10.35 sec.
Processing - SAGA Raster values to points .......... | 380 sec.
SAGA GUI - Grid Values to Points ........................... | 130 sec.
(At the moment I could not run) GRASS r.to.vect ...... | not timed.
(This may not be a fair comparison, because SAGA tools return x and y coordinates along with the raster values).
