8051? This processor is as old as bacteria... useful for some but It can't measure with AVR by any means. The instruction set is making even simple operation (say a=b;) tens instructions long, and these usually are 4 clocks per instruction. Dog slow by architecture and implementation.
duh, look at modern versions like from Silicon Labs -- single-clock instructions, real I/O ports. Nobody uses the Intel 12-clock 8051s any more.
