Apple M2 Pro and Max Chips Repeat a Successful Upgrade Strategy
First the M2. Now we’ve got the M2 Pro and M2 Max. Maybe we’ll see an M2 Ultra processor powering Apple Mac Pro computers in the coming months.

With its M2 Pro and M2 Max processors, Apple is repeating a strategy that worked well for its earlier M1 designs. By grafting some extra circuitry onto an efficient chip foundation, Apple can offer a significant upgrade to its new M2-based MacBook Pro laptops without a full chip overhaul.
Apple introduced its first in-house Mac processor, the M1, for MacBook Air laptops that arrived in 2020. The M1 already took advantage of chip design work for the iPhone’s A-series chips, but Apple beefed up the M1 with more processing cores to make the M1 Pro and M1 Max in late 2021 for higher-end MacBook Pro laptops. Then, in 2022, it glued two M1 Max chips together into the top-end M1 Ultra.
Now, Apple is headed the same route with the M2, which debuted in 2022 and now is joined by the M2 Pro and M2 Max for new MacBook Pro models. If history continues to repeat itself, we could see a Mac Pro based on a hulking M2 Ultra processor in the coming months.
The chips’ speed boost over M1 equivalents that debuted 15 months ago is significant — 20% at least by Apple’s measurements. Owners of year-old M1-generation MacBook Pro laptops to upgrade. But for those using older Macs based on the older Intel chips Apple ejected from its product line, the speed boost and better battery life could be much more compelling.
«These new Macs should help entice moving off Intel to M series in 23,» Creative Strategies analyst Ben Bajarin said in a tweet Tuesday. His firm estimates 42% of Mac owners in the US are still using Intel-based models, and the fraction is probably higher worldwide.
Apple didn’t respond to requests for comment. Intel declined to comment.
How did Apple speed up the M2 Pro and M2 Max chips?
The M2 Pro and Max chips are faster thanks to new designs for the chip’s central processing unit cores for general computation and graphics processing unit cores for handling graphics tasks and some other jobs that work on GPUs. The new designs also have more CPUs, GPUs and another core type for accelerating artificial intelligence tasks, which Apple calls its Neural Engine.
The M1 Pro has eight or 10 CPU cores, depending on configuration, and the M1 Max has 10. The M2 Pro has 10 or 12, and the M2 Max has 12. The M2 generation is 20% faster, Apple said, citing unspecified but industry standard speed tests.
CPU performance is the foundation of everything a processor does, and all the M-series Pro and Max models employ four power-efficient CPU cores for better battery life. The remaining CPU cores offer higher performance cores for more important work. Intel also has adopted this approach, pioneered for smartphones.
For GPUs, used for tasks like playing games and editing photos and videos, the M1 Pro came with 14 or 16 cores and the M1 Max with 16 to 32 cores. The M2 Pro boosts that to 16 or 19 GPU cores, and the M2 Max to 30 or 38. The M2 GPU performance is 30% faster, though part of the speed boost comes from better cache memory on the chip, Apple said.
The neural engine has 16 cores on both M1 and M2 generations, but Apple boasts its AI performance is 40% faster with the new chips. AI software is just getting started, but it’s used in important jobs like some Adobe Photoshop image editing, and you can expect that AI performance to become more and more important as more developers figure it out.
Speed boosts compared to Intel-based Macs, which use years-old Intel chips, are more notable. The M2 Pro is 2.5 times faster at compiling software and 80% faster at Photoshop image editing compared with an older 16-inch MacBook with an Intel i9 processor, Apple said. As for the M2 Max, it’s twice fast at video color adjustments and six times faster at Da Vinci Resolve video editing.
Some of the speed boost on the M2 Max comes from faster memory transfer, doubling to 400 megabytes per second, which helps with data-heavy chores like video editing and 3D modeling. The M2 Max new models also accommodate up to 96GB of memory, up from 64GB on the M1 Max.
We won’t see third-party speed tests until MacBook Pro reviews with the M2 Pro and Max processors arrive. CNET editor Dan Ackerman gave the M2-based MacBook Air an editor’s choice accolade, citing its «excellent performance and battery life.»
That model came with a $200 price increase over its predecessor, though, and the M2-generation MacBook Pro laptops aren’t cheap, either. The model with a 14-inch screen and lowest-end 10-core M2 Pro costs $1,999; with a 12-core M2 Max and other improvements, the price increases to $3,099. The 16-inch models start at $2,499 but rise to $3,499 with an M2 Max processor and more storage capacity.
How are the M2 Pro and M2 Max chips built?
As with all Apple-designed processors for the last few years, Taiwan Semiconductor Manufacturing Co. (TSMC) builds the chips.
As with the M2, the M2 Pro and Max are built with a second-generation 5-nanometer manufacturing process. (A nanometer is a billionth of a meter, and chip manufacturing processes with lower nanometers refer to more advanced manufacturing processes. However, for years now, the numbers have been mere labels of convenience, not actual measurements signifying actual miniaturization progress.)
New manufacturing processes shrink chips’ fundamental electronic elements, called transistors, although that miniaturization is harder these days. That permits more circuitry on a chip. The transistor tally increased from 33.7 billion in the M1 Pro to 40 billion in the M2 Pro; the Max models increased from 57 billion to 67 billion.
TSMC has begun mass product manufacturing on a newer 3 nanometer (3nm) process. Expect that to be used for future iPhone, iPad and Mac processors, a move that should permit even more transistors.

New Study Shows Smartwatch Stress Sensors Have No Idea What They’re Doing
Dutch researchers found that not only are stress sensors inaccurate, but they sometimes report the opposite of user experiences.

You might want to think twice before you put a lot of stock in the latest stress charts from your fitness wearable. A recent study from the Netherlands’ Leiden University, published in the Journal of Psychopathology and Clinical Science, has found that when smartwatches and similar devices record readings on stress, fatigue or sleep, they’re frequently getting it wrong.
Researchers studied 800 young adults using the same Garmin Vivosmart 4 smartwatch model. They compared the data the smartwatches produced with the reports that the users created four times per day about how sleepy or stressed they were feeling. Lead author and associate professor Eiko Fried said the correlation between the wearable data and the user-created data was, «basically zero.»
A representative for Garmin did not immediately respond to a request for comment.
Stressed or sex? Your watch doesn’t know
So why do wearables like fitness smartwatches get it so wrong? Their sensors are fairly limited in what they can do. Watches like these need to be worn correctly at all times (a loose or tight watch may give poor readings, for example), and they typically use basic information like pulse rate and movement to make guesses about health.
Those guesses don’t always reflect real-world scenarios. A wearable may identify high stress when the real cause of the change was a workout, excitement over good news, or sex. There are so many potential alternatives to stress or fatigue that the watches in the study never really got it right — and the devices sometimes guessed the complete opposite emotional state from what users recorded.
The Dutch study did note that Garmin’s Body Battery readings, which specifically measure physical fatigue, were more reliable than stress indicators, but still inaccurate. And sleep sensing performed the best of them all, with Garmin watches showing a two-thirds chance of noting the differences between a good night’s sleep and a bad one.
It’s also worth noting that smartwatch sensors can become more accurate as technology improves. It would be interesting to run a similar study with the newer Garmin Vivosmart 5 to see if anything has improved, as well as see if other models like the latest versions of the Apple Watch have similar accuracy results.

Drag x Drive Proves the Switch 2’s Mouse Mode Controls Are Fantastic
Nintendo has done it again with a great new way to play games on its just-launched console.

Nintendo’s next summer title — and one of the few new games for the Switch 2 soon after its June launch — is the multiplayer wheelchair basketball game, Drag x Drive. It uses the console’s new Joy-Con mouse controls to simulate moving the wheels of your chair (or vehicle, as it’s referred to in-game) while playing short three-on-three matches. While it does take some getting used to, it shows off how well this new input mode works and harkens back to an era of motion-controlled gaming made popular on Nintendo’s Wii.
Playing Drag x Drive is unique, reflecting the Switch 2 new tech. You detach each Joy-Con 2 controller from the system, place the sensors face down on a surface (which can range from a table to even your legs), and slide the controllers forward and backward to move the wheels respectively. I actually found it more comfortable on my wrists to use the controllers positioned a little wider on my thighs instead of straight up and down on a table.
Learning to play has a steep curve, and I found my shoulders getting tired quickly as the game kept reminding me that longer strokes would move my character faster on the court. For anyone who experienced Tennis Elbow back when WiiSports came out, Drag x Drive’s bodily wear-and-tear will be familiar.
The mouse’s controls are good — better than I expected, in fact. They feel snappy, and I was able to pull off some higher-level maneuvers when I got used to it. And as you move, you can feel a subtle vibration in each hand to help you dial in how much force you’re inputting. Moving the controllers at different speeds will adjust the turning radius. Braking (by pressing the R or L buttons) can be done independently of each wheel to further your control. There are even tricks you can pull off by using breaking and lifting the controllers in specific combinations, which the game points out will help you perform more advanced blocks and interceptions.
Controls are the big novelty of Drag x Drive and take time to get used to, though the court and game modes offer their own unique challenges.

Moderately deep mechanics for a $20 game
The primary mode is a 3-minute three-on-three game that’s reminiscent of Rocket League (without the jetpacks). There’s an indicator always pointing toward the oversized ball. Rolling into it will pick it up. If you’re going fast enough (represented by a flashing light on your back) and crashing into someone head-on will knock it loose. And if you raise one of the joy-cons off the surface, you will lift the ball, flicking your wrist will make a shot.
Since the court is kind of a skateboard-style bowl, you can even roll up into the air from the sides and shoot or dunk from above. These trick shots will award players with more granular points, for example, an aerial shot might award you 2.3 instead of the standard two you’d see in typical basketball. But you can still land a three-pointer from outside the boundary, but you’ll have to be lined up real well while the other five players aren’t slamming into you.
Defense also works just like you’d expect, with positioning playing the most important role. Pressing the R and L buttons together will pass the ball to a teammate. If an opponent is in the way, they can intercept. This is key since I witnessed many teams pass a ball way down the court to an isolated player while we tried to race after them to stop the shot. Like every sport, you’ll want to spread out and cover someone instead of clumping all together around the ball, like most new players often do.
While Drag x Drive curiously doesn’t refer to anything as a wheelchair (or even highlight the awesome and inclusive sport of wheelchair basketball), it’s really wonderful to see this representation. The characters can also be swapped out for one of three unit types: defense, forward or guard, all with different speed and power stats. From there, you can customise your character’s outfit and gear, with more to unlock as you play.
Outside of the online play, there are also nine different bot difficulties you can take on, so the game is playable in single player. There are also several minigames stationed around the hub area. These include a timed race and a rebound mode where you need to chase after a bouncing ball in the hub before time runs out. They’re pretty short and not all that interesting, but they will reward you with medals to unlock gear. There are also some obstacles positioned around to play with. One example is a giant jump rope that you can bunny hop over.
There isn’t a typical career or story campaign to work through — the main draw is the one core multiplayer mode. Considering the low $20 entry price, I wouldn’t expect anything super in-depth, making this more of a unique application of the Switch 2 Joy-Cons’ mouse mode than a long-lasting play experience.
Drag x Drive is a shallow experience, but the skill ceiling has a lot of potential. Its low entry price makes it an easy recommendation, even if you’re just interested in trying out the new mouse controls that the Switch 2 offers. If Nintendo chooses to support the game with more content in the future, I would love to see limited-time events and more game modes get added, building on the bones of one of the most unique sports games to come out in years.
Drag x Drive comes out on Switch 2 on Thursday.
