What's the real difference between S17 and S17Pro?

Hey, I’m new here. Can someone explain what’s different between S17 and S17Pro? I checked the hash boards, and the only thing I see is that the S17Pro has one extra notch. Is that it?

They might look similar but trust me, they aren’t identical. If you examine the circuitry and some components, you’ll see differences. Check out some parts lists for both models if you wanna really compare. Oh, and don’t mix their programs, they won’t work.

Got it, thanks! Looks like the S17 Pro parts kit is actually more complete than the S17.

For sure! Manufacturers are focusing on energy-efficient ASIC miners these days. The S17 uses around 2094W while the S17 Pro is better at around 1975W. The efficiency numbers tell the tale too. S17 is like 39.5j per hash and S17 Pro is 37.26j per hash. Pretty clear which one’s better, right?
