H2H: TaylorMade P790 irons vs Mizuno JPX 925 Forged irons

Let's take a look at some of the key technologies in the TaylorMade P790 2025 irons.

One of the key additions to this new TaylorMade P790 range is the new face material. This all-new P790 uses a new forged face material, the 4340M. This material is 20% stronger, allowing engineers to design the face thinner and faster than previous models.

When compared to the previous model of P790 irons, the use of a 4340M material created a 24% larger sweetspot for a more consistent distance from the top of the set to the bottom. These are also some of the most stable irons TaylorMade has ever made. That’s due to strategic repositioning of up to 40g of tungsten internally, and FLTD CG that positions the centre of gravity lowest in long irons for easier launch and playability, and progressively higher in the shorter irons for precise spin, distance and trajectory control.

Tungsten weighting has been moved lower in the long irons, lowering the centre of gravity. As the set progresses up through the 7-iron, the tungsten weight shifts closer to the toe. This increases both stability and MOI in the middle of the set, further enhancing forgiveness and delivering consistent distance and overall performance. Tungsten isn’t found in the 8-iron through pitching wedge, allowing the centre of gravity to sit higher in the head where it enhances control.
 
You still have the Thick-Thin Back Wall Construction which has the honeycombed cutouts across the internal back wall to remove excess weight. This allows engineers to strategically position more weight lower in the clubhead to achieve consistent performance. The Thru-Slot Speed Pocket is also found in the 4-7 irons. This is where most mishits occur and protects ball speeds, which ultimately translates to consistent distance. The classic SpeedFoam Air fills the hollow body construction of P790 irons further ensuring that crisp feel.

Let’s take a look at some of the key technologies in the Mizuno JPX 925 Forged range of irons.

The Mizuno JPX925 Forged features the Contour Ellipse Face. An advanced multi-thickness face profile optimises ball speed across the whole face, giving impressive ball speed even on mishits.

In these irons, Mizuno employs its Grain Flow Forged HD process. The long irons (4-7) in the JPX 925 Forged series are crafted from Chromoly 4120, a material known for its exceptional strength and malleability, enabling higher ball speeds and easier adjustability. While this still feels great, emphasis is placed on performance, particularly in clubs that are more likely to be mishit.

The shorter irons (8-GW) are forged from 1025E Pure Select Mild Carbon Steel, a material that delivers superior control, precision, and the legendary buttery feel Mizuno players expect. Together, these materials ensure a flawless transition through the set, offering the perfect balance of speed, precision, and feedback. This is a key part of the design of these irons, which improves turf interaction. The leading edge is gently bevelled for a clean entry into the turf, while a hard-cut trailing edge allows for a smooth exit for superior uninterrupted ball contact.
