"I have studied the data sheets ... Obviously, they are NOT the "same processor"." Oh? What instructions are different? What micto-architectural differences are there? Or are you claiming that the 8 bit data bus makes the 8088 a hybrid 8/16? Then, does the 64 bit FSB of the x86 processors make them hybrid 32/64 bit processors or even full-blown 64 bit machines?

Dear Yousef: Your company called it a 16 bit chip. Are you calling your company liars? If you want, you could call the fact that 8080/8085 and the Z80 used 16 bit addressing making them 16 bit processors. But, their standard add one register to another instruction did only 8 bits. The standard add one register to another command for both the 8088 and 8086 did 16 bits even though they had 20 bit addressing. The standard add one register to another in the 386, 486, Pentium, P2, P3, P4, K6, K6-2, K6-3, Athlon and Duron works on 32 bit numbers. They have 32 bit addressing (36 bits virtual). The AXP64 and Opteron's version works on 64 bit numbers, addresses 40 bits physically, 48 bits virtually and can address 64 bits in future versions. Any way you cut it, Opteron and AXP64 address far more memory than any other IA-32 processor. Pete
