Pois, opa li agora isto num site:
" According to another thread on the MR forum the new MBP 2.53 use a T9400 (35W) instead of a P9500 (25W). While this means higher power-usage it seems that according to the linked benchmarks the T9400 also delivers better multi-threading performance, while the P9500 seems better optimized for single-threading. "
Isto é verdade? Ou é pura suposição?
