I believe this is the machine referred to:

Temperature was over 2 billion degrees Kelvin.
Here is the big pic:

The outer surface of the sun has a temperature of 6,000°C (11,000°F). The core of the sun is 15,000,000° C; or 27,000,000° F.
The man-made machine produced heat 133 times that of the core of the sun. The earth was not destroyed due to containment. A full force, extended burst from Superman would be different however and would most likely destroy a good portion of the planet, and all life would die that wasn't Superhuman.
For reference, the fireball area of the atomic bomb that dropped on Hiroshima was 7,000 F.
Now let's look at some of the Surfer's on-panel feats:
- flying through the center of a black hole, with no slowdown whatsoever, something which even Superman could not do (Superman was stuck within a black hole for a fair period of time before he managed to get out by flying faster than the speed of light to break the Schwartzchild radius).
- Surviving a Supernova with zero effect.
Amongst other things, showing that for all intensive purposes, Silver Surfer is nigh immune to heat and fire unless it is either backed by cosmic force (firelord) or mystic force (Mephisto). Superman's heat vision hasn't shown to be either, and although it is as hot as the core of the sun (meaning one full strength blast could annihilate planet earth), it still wouldn't be hot enough to even damage silver surfer.
As far as the rest:
Thor, no mjnollir:
Severely damaged, lying on the ground crippled, but alive.
Thanos:
Unharmed, one of his multiple force fields shrugs it off with ease.
Mangog:
Hurting, but alive.
Firelord:
Unharmed, same as Surfer.
WonderMan:
Dead, bones smoking in pile of ashes
Ultron:
Joints fused together thus immobile, but still alive inside.
Hulk:
Smoking and charred, critical condition, most likely would regenerate if he didn't die.
