Here's a comparison of my Ryzen desktop pc and i7 mini pc. My mini pc is better on both metrics - hash/thread and hash/watt.
CPU CORE THREADS CLOCK TDP (WATTS)* RAM RAM SPEED OS Miner HASH/S HASH/THREAD HASH/WATT
Intel i7 8750h (Mini PC) 6 12 3,200 45 Dual 16gb 2,400 Ubuntu 18.04 Rhminer 1.3 2,200 183 49
AMD Ryzen 1950X 16 18 3,600 180 Dual 32gb 3,200 Ubuntu 18.04 Rhminer 1.3 3,100 172 17
* CPU Power Consumption only (excluding other PC components)
The Ryzen desktop is actually quad channel, 2 more ram sticks should get me to 5,000 h/s. But still the i7 8750h is more power efficient.
