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?
