The Callaway Quantum Max and the PING G440 Max aren’t niche clubs built for a specific type of player. They’re two of the most versatile, well-rounded drivers in our 2026 driver test and they’re exactly the kind of clubs that end up on the short list for a wide range of golfers at a fitting.
The challenge is that on paper they look almost identical at certain swing speeds.
The numbers behind those scores tell very different stories so I took a deep dive into the Quantum Max versus the G440 MAX to find out what you actually need to know based on your swing speed.
Slow swing speeds (Under 90 mph)
The G440 MAX wins on overall score at slow swing speeds with an 8.9 versus the 8.5 for the Quantum Max.
When you dig a little deeper into the numbers, you’ll find the G440 MAX is the tighter, more accurate option at slow speeds. It had a 63.6 percent straight rate. For a slow swing speed golfer who needs to find fairways, those are numbers to pay attention to.
The Quantum Max wins on total distance at 199.4 yards versus the G440 MAX’s 195.3.
The playable rates for these two drivers are virtually identical. Where the G440 MAX separates itself is the shot area. Its shots cluster into a tighter spread of 2,136 square yards versus the Quantum Max’s 2,307. When it misses, it misses in a smaller window.
| Metric | Callaway Quantum Max | PING G440 MAX |
|---|---|---|
| MGS Score | 8.5 | 8.9 |
| Total Distance | 199.4 yds | 195.3 yds |
| Carry | 181.0 yds | 183.8 yds |
| Ball Speed | 115.83 mph | 117.50 mph |
| YFC | 10.96 yds | 10.09 yds |
| Straight Rate | 59.1% | 63.6% |
| Playable Rate | 95.3% | 95.4% |
| Shot Area | 2,307 sq yds | 2,136 sq yds |
| Spin | 2,109 rpm | 2,717 rpm |
| Smash Factor | 1.413 | 1.422 |
Mid swing speeds (90–105 mph)
Both clubs score 9.2 at mid speeds.
The Quantum Max is a little straighter; its 60.4 percent straight rate leads the entire mid-speed test. The G440 MAX still finds a way to get the ball in the fairway and its 90.6 percent playable rate is the better of the two.
This is where you will want to make sure you go through a proper fitting and experience the differences first-hand. They are minimal at mid swing speeds.
| Metric | Callaway Quantum Max | PING G440 MAX |
|---|---|---|
| MGS Score | 9.2 | 9.2 |
| Total Distance | 255.4 yds | 252.5 yds |
| Carry | 241.6 yds | 237.4 yds |
| Yards from center | 14.10 yds | 13.95 yds |
| Straight Rate | 60.4% | 56.5% |
| Playable Rate | 89.0% | 90.6% |
| Spin | 2,241 rpm | 2,556 rpm |
| Smash Factor | 1.426 | 1.445 |
High swing speeds (Over 105 mph)
While there wasn’t much of a story to tell for mid swing speed golfers, things change at high speeds.
The Quantum Max scores 9.7 in our high speed test and wins best overall driver at this speed. The G440 MAX scores 9.1.
The Quantum Max averages 295.7 yards at high speeds, 8.4 yards ahead of the G440 MAX. That gap is driven almost entirely by spin. The Quantum Max runs at 2,123 rpm while the G440 MAX sits at 2,646.
The engineering that makes the G440 MAX forgiving and consistent at slower speeds works against it when a faster swinger delivers more speed into the face.
Here’s the updated high speed table:
| Metric | Callaway Quantum Max | PING G440 MAX |
|---|---|---|
| MGS Score | 9.7 | 9.1 |
| Total Distance | 295.7 yds | 287.3 yds |
| Carry | 278.2 yds | 275.5 yds |
| Yards from center | 18.53 yds | 17.39 yds |
| Straight Rate | 53.9% | 52.7% |
| Playable Rate | 79.7% | 81.7% |
| Spin | 2,123 rpm | 2,646 rpm |
| Smash Factor | 1.428 | 1.430 |
Which should you buy?
We will always recommend a proper fitting but this is what the results of the test have to say about which of these two drivers you should buy based on this data.
| Speed | Quantum Max Score | G440 MAX Score | Edge |
|---|---|---|---|
| Slow | 8.5 | 8.9 | G440 MAX: straighter and finds more fairways |
| Mid | 9.2 | 9.2 | Tie: Quantum Max slightly straighter, G440 MAX slightly more playable |
| High | 9.7 | 9.1 | Quantum Max: more distance and lower spin |
Final thoughts
Both drivers were among the stronger performers in our 2026 test and either could be the right call, depending on your swing speed and priorities. The G440 MAX is the pick at slow speeds. It’s a toss-up at mid speeds and the Quantum Max pulls clear at high speeds. Before you decide, see how both clubs performed across the full field in our 2026 Driver Test.

I have both Drivers. The G440 sits in the garage. No matter what shaft was tested the spin was always at the 3500 mark, whereas the Callaway was below 2900 consistently and longers. Same delivery patterns. So would love an explanation.
