According to Suchet in early 1813, his army lost say 8,000 - 10,000 men total. This includes an Italian Division send back to Italy, disarming of German units and sending cadres of officers and men (about 2,000 total) to France to rebuild units.
Wellington's victory put the finishing touches on the French retreat from Spain including Suchet who withdrew all the way to Barcelona. The French left garrisons in Spain though, as strategically useless as the garrisons Napoleon had left in Germany in 1813. This also reduced the number available to defend southern France.
It was due to the treaty of Valencay (signed 11 December 1813) that in early 1814 Napoleon ordered the withdrawal of troops from Soult and Suchet.
Imagine if Wellington only faced half of these forces before Vittoria? The only thing that might have stopped him crossing the Pyrenees sooner could have been the situation in Central Europe.
Even here if he crossed into France earlier than he did, it might have given impetus to the Allies before the battle of Leipzig? There is evidence that Vittoria encouraged the Allies.
