Asa cum stiti, AMD Radeon RX 7900 GRE este echipata cu 80 CU, adica 5120 unitati de procesare, 80 ray accelerators, 160 AI accelerators si 160 ROPs, care comunica cu 16384 MB GDDR6 cu ajutorul unei magistrale de 256 de biti. Noi am testat pana acum implementarile Sapphire si ASRock, in cazul carora nucleul avea o frecventa de boost declarata de 2333MHz, memoria fiind tactata la 2250MHz. Ei bine, cei de la GIGABYTE au pastrat frecventa memoriei, insa frecventa de baza este acum 2052MHz, in loc de 1972MHz, in timp ce frecventa boost este 2391MHz, fata de 2333MHz in cazul celorlalte doua implementari testate de noi pana acum.
