Highlighted cells differ between the two sets. Lofts and lies are factory standard.

Lofts compared

S3
AMP Cell

Lofts differ on 4 of the 11 clubs the two sets share. A lower point is a stronger loft.

What the differences mean

At the 7-iron, the S3 is 31° and the AMP Cell is 31°, identical at the club most golfers compare on, although other clubs in the sets differ. Across the 11 clubs both sets share, the AMP Cell averages 0.3° stronger, with the largest gap at the 4-iron (22° vs 21°).

Both are game improvement irons, built for roughly 10 to 25 handicaps. Perimeter-weighted cavity backs with wider soles, more offset and stronger lofts, aimed at mid handicaps. Because they target the same golfer, the decision comes down to the specific loft, feel and shaping differences rather than who the sets are made for.

The S3 is listed as investment cast multi-material and the AMP Cell as cast body with welded high-strength steel face (metalwood face-weld). With the build method this similar, differences in feel come down to head size, sole width, topline and offset rather than how the heads are made.

The AMP Cell came out 1 year after the S3, but it is a different line rather than a direct replacement, so the two were designed for different golfers as well as different seasons.

Which should you choose?

The AMP Cell is the stronger-lofted set — up to 1° stronger than the S3 on matching clubs. Expect longer carry per numbered iron but a flatter descent angle; gapping at the wedge end is where that shows up.
