I'm looking for material very much like Marduk's "Panzer Division Marduk". Absurd intensity and blast beats throttling you like a machine gun so to speak.

The other "norsecore" bands

While the following aren't much like Marduk, they have the exact qualities that you've listed.
Ruin Lust Vicious, heavy and absolutely pummeling black metal with a death metal edge. One of the most overwhelming bands I've seen live.

Revenge One of the many essential "war metal" bands. J.Reed's drumming is as intense as it gets (check out Conqueror's War Cult Supremacy as well).

Knelt Rote. Grindcore infused with black metal. Super intense. Later stuff becomes more blackened death metal.

Infernal War

Infernal War is my top recommendation as well.

Enthroned is an obvious one and one of the biggest names in this style.

1349 is another obvious one with Frost blasting like crazy on the drums.

Also Dark Funeral as another big name band.

Funeral Mist may work. They are definitely intense.

Naer Mataron has a lot in common with this style.

Anaal Nathrakh is black/grind you need to check out.
