Apple M4 arrives less than a year after M3 as the AI PC battle looms

Something to look forward to: With its newly announced iPads, Apple is fast-tracking the introduction of its M4 processors to compete in the upcoming AI PC race. Although the Cupertino giant claims it has the most powerful NPU on the market, Qualcomm might disagree. Meanwhile, Intel is preparing significant AI performance upgrades over the next year, and Nvidia claims that its GPUs reign supreme in generative AI.

Apple's event mostly focused on iPads, but the presentation also introduced the M4 – the company's next-generation in-house SoCs. As expected, the processors offer performance improvements over the M3 and M2, but Apple's rundown also delivered a preview of the company's AI PC strategy for 2024.

The segment focusing on the M4 could be considered a sneak peek, as the company only unveiled the standard variant and mostly focused on its performance improvements over the last iPad Pro model. Apple is expected to fully reveal the M4 lineup at WWDC in June, likely with new Macs.

The iPad Pro is skipping the M3 altogether, a chip Apple introduced just last year. This means that the M4 brings some of its predecessor's features to tablets for the first time, such as a 3nm node, dynamic caching, mesh shading, and ray tracing. The CPU is 50 percent faster than the M2 featured in the last iPad Pro, and the GPU is four times faster.

Compared to the standard M3, the M4 features a similar 10-core GPU but increases the CPU core count from eight to 10. Additionally, the SoC gains 3 billion transistors, bringing the total count to 28 billion.

One of the new features of the M4 is a display engine to help the new iPad Pro's OLED screens produce better brightness and colors. However, the most significant improvement of the new SoC is likely its enhanced AI performance.

Prior reports indicated that the M4 would mark the beginning of Apple's push toward offering products that run on-board AI applications, which are less reliant on cloud services used by programs such as ChatGPT, Bard, or DALL-E. The company's flex that, at 38 TOPs, the M4's neural engine is the world's fastest, appears to vindicate the rumors, but competition is set to heat up quickly.

AI PCs featuring Qualcomm's Snapdragon X Elite should begin shipping sometime in mid-2024. The company claimed that its new SoC outperformed M3, and the spec sheet's 45 TOPs of NPU performance suggests it might also compare favorably against M4.

The Arm-based Snapdragon X Elite aims to become the Windows equivalent of Apple Silicon. Apple's latest processors have enabled recent games like Resident Evil Village and Assassin's Creed Mirage to run on iPhones and iPads. In a similar vein, Qualcomm showed off its upcoming chip maintaining playable framerates in modern titles like Baldur's Gate 3 (which might come to Apple devices next year).

Meanwhile, Intel, which began the push for AI PCs with Meteor Lake late last year, plans to significantly increase its AI capabilities with Panther Lake next year. The 18A (1.8nm) chip will double the AI performance of Arrow Lake, which is expected to launch in the second half of 2024.

While Apple, Intel, Qualcomm, and AMD focus on enhancing on-device AI using NPUs, Nvidia believes GPUs are better suited to the task. The company claims that its RTX dedicated graphics chips, millions of which are already in the wild, can achieve between 100 and 1,300 TOPs. Nvidia is set to introduce the next generation of RTX, codenamed Blackwell, later this year.

Yeah Qualcomm, AMD and Intel will all have apu's capable of well over 50 TOPS this year. NPU's on AMD and Intel are tripling in performance, and then the iGPU also can do AI. AMD said Strix will have 75 TOPS total performance IIRC which is similar to Qualcomm's claims.

What I want to know is how the M4 differs from the M3 (NPU aside). It seems too quick for a full upgrade. Will next gen Macbooks use M4 or wait for M5?

Anyway at the end of the day the iPad Pro is excellent hardware hamstrung by a garbage OS that stops it well short of being a true laptop replacement and the price is ludicrous. You can get a Macbook Air far cheaper with more RAM and storage as you have to add in the cost of keyboard and pencil for iPad. What sort of scum company doesn't give you the pencil for free given the ludicrous pricing of the iPad Pro. In Australia we ar elooking at over $5K for 2TB iPad Pro 12.9" with keyboard and pencil, far dearer than well specced Macbook Pro.
 
Anyone seen what the NPU could be used for?
Generative AI applications for the most part (at least early on). You can expect many hybrid applications with ondevice AI for simpler jobs and offloading to a server big jobs.

This picture should give you a glimpse of what we'll see in the short term (slide from Intel/MSI):

The NPU is pretty much essential in reducing the over-reliance on server sided workloads. It will also especially help laptops because of how power efficient the NPU is compared to using your GPU/CPU.

Just so you understand just how big the rush to include AI acceleration in applications is, even the regular Paint app from windows is getting AI image generation/editing.

In spite of my nerdiness I currently have ZERO use for AI capabilities in my personal hardware. While I use AI daily ALL processing is done server-side. Mind you the AI revolution is real but it has no place in my machines.
So for me what PC AI capabilities come down to is...BUZZWORD and at the moment I'm 100% unwilling to pay for that.
Of course there's a possibility that the hardware makers will come up with something that's actually useful and attractive to me.
Curious to see how this will unfoid - definitely interesting times, these.
 
M4 is a testament that Apple is running out of tricks in their sleeves. Essentially it’s looking pretty much like the M3 when it comes to performance. If anything, Apple’s SOC seems to be in the same direction as Intel’s chips, where they spam users with a bunch of e-cores while pushing total power draw to squeeze out more performance. In the iPad, it’s guaranteed to throttle badly given that the M3 MacBook Air with better passive cooling solution is already throttling a lot.
And I agree that while the M4 is still fast, it’s severely hampered by the OS deliberately gimped by Apple. So hard pass for me even as a M1 MacBook Pro user.
 
This is like buying a mansion - without furniture.
Awesome performance bundled with an extremely limited OS. Like - why haven’t they just allowed the ipad pro’s to dual boot with ipad os and MacOS, it’s more than powerful enough to use MacOs

The answer's simple: Apple doesn't want the iPads to compete with the MacBooks.
I for one cannot blame them yet I find it strange that Apple implies that iPads can be used as full-fledged laptops which simply isn't true.
For that reason while I'm planning to replace/update my old iPad sometime soon I'll happily skip the keyboard. I own a REAL laptop thank you very much.
