Swift 3 is more powerful than Swift 1.
Here's a good comparison between the two: https://www.gadgetsnow.com/compare-...aptop-Core-i5-7th-Gen4-GB256-GB-SSDWindows-10
Some additional comparisons, between CPUs:
Swift 1 (N3710) vs Swift 3 (300U): https://cpu.userbenchmark.com/Compare/Intel-Pentium-N3710-vs-AMD-Athlon-300U/m141841vsm852003
N4100 vs 300U: https://cpu.userbenchmark.com/Compare/Intel-Celeron-N4100-vs-AMD-Athlon-300U/m407836vsm852003
Ryzen 3 1200 vs 300U: https://cpu.userbenchmark.com/Compare/AMD-Ryzen-3-1200-vs-AMD-Athlon-300U/3931vsm852003
Notes:
Comparison site doesn't have N4120 in it's database, so picked the closest match: N4100 (slightly weaker than N4120).
Also, i picked the weakest Ryzen 3 CPU for comparison since you didn't specify which Ryzen 3 you're talking about.
are the Pentium / Celeron / Athlon too outdated and unappealing?
(i can see percentage numbers but idk how it trabslates into realworld use)
