Asa cum stim deja, NVIDIA GeForce RTX 5080 FE integreaza nucleul GB203, produs in litografie 5 nm EUV (TSMC 4N) in fabricile TSMC din Taiwan, acesta fiind echipat cu 45.6 miliarde de tranzistori, dispusi pe o suprafata de 378 mm2. Si daca RTX 5090 ne punea la dispozitie 21760 shadere, 680 Tensor cores, 170 RT cores si 176 ROPs, NVIDIA GeForce RTX 5080 FE este echipata cu 10752 shadere, 336 Tensor cores, 84 RT cores si 112 ROPs.
Ei bine, ASUS ROG Astral GeForce RTX 5080 16GB GDDR7 OC Edition are doua profile de BIOS intre care putem comuta cu ajutorul switch-ului dispus pe PCB, mai precis Quiet si Performance. Profilul performance este cel implicit, acesta venind cu o frecventa de baza de 2295MHz si o frecventa de boost de 2760MHz, in timp ce memoria este tactata la 1875MHz.
Prin comparatie, GIGABYTE GeForce RTX 5080 Gaming OC 16G are o frecventa de boost declarata de 2730 MHz, in timp ce implementarea Founders Edition are o frecventa boost de 2617MHz. Lucrurile nu se opresc insa aici, deoarece mai exista un profil, pe care il putem activa daca instalam ASUS GPU Tweak III, mai precis profilul OC. Acesta are o frecventa de baza de 2315MHz si o frecventa boost de 2780MHz, profilul de putere fiind setat de asemenea la 110%.
