Half as much, without feats and magic items (which exist in most games, and can be added to yours if you see a problem with your martials).Sure. I think I've conceded that a wizard without spells does less damage than a fighter or rogue. As you've stated here, it's roughly half as much.
Do you really want to compare the 'at will' DPR of a Spellsniper/ Elemental Adept Firebolt/ Red Dragon Sorcerer with Cha +5 at 11th level, armed with a Wand of the War mage +3, with that of a +3 Crossbow/ +3 Bolt, Sharpshooter/ Crossbow expert Fighter with Archery style at the same level?
+12 to hit (3d10+5 damage) vs +12 to hit (x3) dealing a total of 3d10+63 damage.
Obviously an outlier, but the point stands. Feats and Magic items favor martials far more than they do Casters skewing the numbers more in their favor.
Notably, the Fighter also has 50 percent more HP, and a likely higher AC (no resource usage remember). Add in magic items, and (again) the Fighter benefits the most again.
