The Taylormade P790 UDI is designed for low handicap players with fast and very fast swing speeds. It can produce low penetrating bullets that carry a country mile off the tee.
The Taylormade Stealth UDI is the more user-friendly driving iron of the two. It caters to a much larger handicap range (0 – 15), it launches a bit higher, and you don’t need an ultra-fast swing in order to put it in the bag. You do need to play stiff shafts though. Both the Stealth UDI and the P790 UDI are only available in stiff shaft and extra stiff shaft options.
Now that you know a bit more about each club, we can dive into the details of this comparison between the Taylormade Stealth UDI vs P790 UDI.

Key Differences - Stealth UDI vs P790 UDI
1. Loft Options
The Taylormade P790 UDI is only available in a 2-iron loft (17°). The Taylormade Stealth UDI is available in a 2 iron loft of 18°, a 3 iron loft of 20°, and a 4 iron loft of 23°.
Based on the loft specs, it’s pretty clear that the P790 UDI will produce a more penetrating ball flight. The lower loft combined with the lower backspin numbers offered by the P790 means that it is very well suited to hitting stingers off the tee.
Conversely, the loft options of the Stealth UDI are better suited to mid and low handicappers with medium to medium-fast swing speeds. In fact, you might find that a certain percentage of golfers can actually hit the 3 iron version of the Stealth UDI further than the 2 iron version of the Stealth UDI, due to the higher apex of the 20 degree version.
2. Loft Adjustability
Loft adjustability is a massive selling point for the Stealth UDI. The Loft and lie can be adjusted +/- 2˚, making it a far more versatile club overall.
Dialing in the ideal loft of a driving iron is super important. For instance, when reviewing the Ping G425 2 Iron Crossover, it became apparent that my swing speed wasn’t high enough to justify putting it in the bag. In reality, the G425 3 Iron Crossover is a better fit for my game.
If you select the Stealth UDI 3 iron, for instance, you have the option to loft it down to 2 iron specs, keep the default 3 iron loft, or loft it all the way up to a 4 iron.
Having the freedom to find the ideal loft for your swing speed and ball flight is a massive win for the Stealth UDI. You are less likely to be left with a club that doesn’t actually make it into your permanent setup.
3. Forgiveness
In terms of forgiveness, it should be pretty clear that the Stealth UDI is more forgiving than the P790 UDI. This means that you can get away with off-center strikes with the Stealth UDI, but that isn’t necessarily the case with the P790 in your hands.
With that being said, even though the P790 UDI isn’t ultra forgiving, the reviews online are very positive. Most of the low handicap golfers that have it in the bag swear by the low ball flight control that it offers.
4. Handicap Range
According to Taylormade’s official guide, the P790 is designed to cater to players with a handicap of 0 – 5. It can be classified as a ‘player driving iron’, which basically means you have to be a pretty solid ball-striker with a reasonably fast swing speed in order to maximize the potential of the club.
On the other hand, the Stealth UDI caters to players ranging from 0 – 15, which is a much wider spectrum of golfers.
While the Stealth UDI might be a bit more difficult to shape left and right, it is probably the better fit for most amateur golfers. You don’t have to be an elite level ballstriker to take full advantage of this club.
5. Hand Availability
Said simply, the P790 UDI is only available to right-handed golfers. The Stealth UDI is available to left-handed players and right-handed players.
Lefties should also take note that the left-handed Stealth UDI is only available in 2-iron and 3-iron lofts (ie there is no 4-iron version for left-handers).
6. Launch, Backspin and Trajectory
Another key difference between the Stealth UDI and the P790 UDI is the launch height and backspin numbers that you can expect with each club in your hands.
The P790 is a low loft, low launch, low spin driving iron. It is literally built to produce a penetrating ball flight that can carry over 250+ yards if you have a high swing speed.
The Stealth UDI offers a slightly higher loft, a mid-to-low launch, and low spin numbers. While this recipe can definitely produce penetrating bullets off the tee, you should find that the apex (maximum height of a given shot) is a fair bit higher than the P790. For medim and medium fast swing speeds, this is actually a good thing. The extra height offered by the Stealth UDI can help you achieve maximum carry distance with a medium to medium-fast swing speed.
7. Swing Speed
Simply put, the P790 UDI is built primarily for fast and super fast swing speeds. If your driver clubhead speed is 110+, then you should definitely consider the P790. You need a super fast clubhead speed to truly unlock the power of this golf club.
The Stealth UDI is built for medium and medium fast swing speeds. If your driver’s clubhead speed is somewhere in the region of 95 to 105 mph, the UDI is probably a better fit for your needs.
If you fall into this swing speed range, you should find it gives you better carry and total distance numbers, due to the slightly higher loft, hollow body construction, and mid-to-low launch trajectory that it offers.
8. Steel Shaft Option
Both P790 UDI and Stealth UDI are only available in stiff shaft and extra stiff graphite shaft variants. However, there is also the option to order the P790 with a steel shaft, if you select the customize option on Taylormade’s website.

Which Driving Iron Is Right For You?
In the end, choosing between these two driving irons comes down to swing speed and forgiveness.
If you are an excellent ball striker with a fast/ultra-fast swing speed, the P790 UDI could legitimately replace your 3 wood. It is very well suited to strong iron players that need a reliable fairway finder.
If you have a pretty fast swing speed but you need a bit more forgiveness, the Stealth UDI is probably the better choice. It will give you a slightly higher launch, and you don’t need to hit the sweet spot every single time. It is user-friendly driving iron that is versatile enough to serve scratch golfers and mid-handicap players with a reasonably fast swing speed.
The only extra point worth mentioning is that if your driver swing speed is somewhere between 90 – 100 mph, the 3 iron version of the Stealth UDI might actually give you better carry numbers than the 2 iron version of the Stealth UDI. Naturally, the only way to put this theory to the test is to go for a club fitting. The point is, when it comes to driving irons, sometimes a bit more loft can be helpful for players with a medium-to-medium fast swing speed.
