Yep - L3 cache is a dealbreaker in Monero mining. Thats why I based all my recent rigs on AMD Ryzen processors - unbeatable in price / performance ratio compared to Intel.
Dont go below 1600 line. But 1600, 1600X, 1700, 1700X - all will be actually profitable and can pay themselves.
All these CPUs can run at 3.8 GHz safely with voltage 1.23V 24/7 while doing really nice hashrates:
Idle system (Win 10): 44 W
1600X @ 3.8 - 540-550 H/s - 95 W at the wall = ca 41 W of power rise against idle - which is really nice, considering its 95W TDP CPU
1700 @ 3.8 - 630 H/s - same wattage as 1600X
You will probably find some GPUs that can match this performance / watt - but most likely they will consume more.
But Monero is overall more "eco-friendly" than ETH. One of my computers with two 1070 and Ryzen 1600X inside is taking 330W while mining ETH+SIA on GPUs and XMR on CPU. But when I switch also the GPUs to XMR - it takes 235W from the wall. Btw 1070 do around 705-710 H/s.
hope it helps guys - even in i7 thread
