Original sentence: AMD Athlon 64, Athlon 64 FX, Athlon 64 X2, Athlon X2, Athlon II, Phenom, Phenom II, Sempron, Turion series and later use one 16-bit HyperTransport link.AMD Athlon64 FX (1207), Opteron use up to three 16-bit HyperTransport links.Common speeds for these processor links are 800 MHz to 1 GHz (older single and multi socket systems on 754, 939, 940 links) and  2 Gz to 2.6 GHz (newer single socket systems on AM2+/AM3 links).Some chipsets though do not even utilize the 16-bit width used by the processors.Those include the nVidia nForce3 150 and the ULi M1689 which utilize a 16-bit HyperTransport downstream link but limit the HyperTransport upstream link to 8-bit.While HyperTransport itself is capable of 32-bit width links, that width is not currently utilized by any AMD processors
Edited sentence: AMD Opterons, Athlon64s and later use 16-bit links.Common speeds for these processor interlinks are 800 MHz to 1 GHz (older and multiprocessor systems) and 2 to 2.6 GHz (newer uniprocessors on AM2+ links).While Hypertransport itself is capable of 32-bit links, that bandwidth is not currently utilized by any AMD processors
