well not really, 3850 used to have one less phase and not all solid capacitors, this 3870 is very robust and follow gigabyte ultra durable reference but comes w/ DDR3 1.0ns, Gigabyte 3850 comes w/ hynix 1.4ns and less components on pcb.
From what I can tell there is same amount of components but on the 3850 there are three capacitors that is of lower capacity. I'm planning to replace those with the same spec'ed capacitors as the 3870 have.
