Gdal_translate allows you to export to another raster, clipping on the way out by either pixel/lines or geo-referenced co-ordinates:
-srcwin xoff yoff xsize ysize:
Selects a subwindow from the source image for copying based on pixel/line location.
-projwin ulx uly lrx lry:
Selects a subwindow from the source image for copying (like -srcwin) but with the corners given in georeferenced coordinates (by default expressed in the SRS of the dataset. Can be changed with -projwin_srs). Note: in GDAL 2.1.0 and 2.1.1, using -projwin with coordinates not aligned with pixels will result in a sub-pixel shift. This has been corrected in later versions. When selecting non-nearest neighbour resampling, starting with GDAL 2.1.0, sub-pixel accuracy is however used to get better results.
