VERDICT
Recommended Ryzen™ 9 7945HX3D
Mixed-use users start with Ryzen™ 9 7945HX3D; specialists check their index. Platform planning: match cooling and board tier to up to 5.4 GHz, 128 MB L3 cache, 16 / 32. Narrow the lens to Gaming Index before you argue with G-SCORE alone. Ryzen™ 9 9955HX still has a case in Content Creation Index, Compute Index—if that is your priority, ignore the total. Double-check Gaming Index if you skipped the middle sections.
