    Ryzen R7 1700 problem in multithread?


      I recently bought a AMD Ryzen CPU, R7 1700.

      I tested the processor with CPU z, in single and multithread built-in bench, and both configurations of SMT: off and on.


      SMT on

      Single: ~1700-1850

      Multi: ~12000-13000


      SMT off

      Single: ~1700-1850

      Multi: ~10000-11000


      I think the results stranges. Little diference between 8 and 16 threads.


      And an other user with same processor in a fórum that i have participated in stock clock, SMT on, get the results below:

      SMT on

      Single: ~1900-2100

      Multi: ~16000-16500


      In a review of Clube do Hardware, the 1700X, more powerfull than 1700, get ~8000 in multithread.



      My setup is this:

      AMD Ryzen R7 1700 @ 3,2Ghz

      XFX RX 480 RS 8GB @ 1288Mhz(Clock)/2000Mhz(Memória)

      MSI B350 Tomahawk (Bios: 1.2)

      2X8GB G.Skill TridentZ DDR4 2933 Mhz (16_18_18_18_38)

      SSD OCZ Agility 3 120 GB (System and Programs)

      2x2TB Seagate Barracuda Sata 3 (Files and Programs)

      EVGA GQ 650 Watts

      Windows 10 64 bits/Crimson Relive 17.3.3


      CPUz 1.78


      My question and resume:

      What is happening? Someone have a similar problem?
