What chipset on A1419 27" 3.4 GHz (late 2013)
Good day!
I have a question about model of PCH which is set on iMac A1419 (Late 2013)? In Ukraine we don't have official services and it happens PCH broken and was troubles with system boot up. In service they replaced controller with Intel B85 which doesn't feel like native controller (form business sector which not designed for speed). After B85 has been installed, system was able to boot up, but GeekBench shown me, what performance of memory, processor and GPU drastically decreased (in 5 times compared to 3 year older iMac).
Additional information about machine:

Was able to find some information (submitted as tests result by users who used bootcamp with windows) basing on motherboard identifier from above and it appear what H87 is expected chipset.
Is there any place where I can look up into this information officially?
