MacBook Pro 16" (M5 Max) review: “Super core” architecture and 40-core GPU deliver beastly performance, but still retains a five-year-old design

Outstanding — THE BOTTOM LINE — Pros & Cons — “Super core” architecture delivers incredible performance

PCMag 2026-03-09 Brian Westover

Context & Ripple Effects

Apple positioned the M5 Pro and M5 Max around a new Fusion Architecture and GPU with Neural Accelerators. This review provides an early product-level test of how that silicon translates into the flagship 16-inch notebook.

The result extends a familiar MacBook Pro arc: the 2024 model added faster M4 chips, a brighter display, and Thunderbolt 5, while the 2023 M3 Max model was already praised for high-end performance. Successive chip and connectivity upgrades have arrived without a comparable redesign of the chassis.

First-order effects

Buyers whose workloads benefit from CPU and GPU throughput get a substantially more capable 16-inch MacBook Pro configuration, according to the review.
The trade-off is more visible for prospective upgraders: the performance advance comes in a chassis the review characterizes as five years old.

Second-order effects

Apple's upgrade case becomes more workload-dependent: owners of recent MacBook Pro generations may need performance needs, rather than new industrial design, to justify replacing their systems.
Rival premium laptop makers have room to compete on enclosure, portability, and fresh hardware design while Apple emphasizes silicon performance.

Third-order effects

If this cadence persists, Apple’s pro-laptop differentiation will increasingly rest on custom-silicon iteration while the physical platform is amortized over longer cycles.
That can split the premium notebook market between buyers who prioritize sustained compute gains and those who expect visible product-design change alongside silicon updates.

The trend: This is one instance of premium PCs using rapid in-house silicon advances to extend mature hardware platforms rather than redesign them each generation.

Holy moly!! Apple M5 Max has a massive PP (Prompt Processing) score. The M5 Ultra is going to be bananas. [image]

Told you guys M5 Max would at least match the desktop RTX 5080! Now let's wait and see how fast M5 Ultra is 😎

For M5 Max NPU/Neural Engine, here's a bit from GPT 5.4 codex playing around with it [image]

@lafaiel yup, here's some cyberpunk in gaming it's easily RTX 5080/5090M performance, without AI upscaling [image]
@lafaiel @lafaiel on x
@mweinbach GPU RT acceleration performance improved a lot. It's up nearly 40% from M4 and even beat the M3 Ultra

Apple made some huge claims about the M5 Max, so I put it side by side with my M4 Max and an M3 Ultra to see what actually changed. One result caught me completely off guard. (NEW VIDEO link in reply) [image]

Here are your M5 Max benchmarks compared to M4 Max and M3 Ultra [image]

You'll have more M5 Max stuff from me once ChatGPT makes this stupid chart (it's been running for 10 minutes) but it's extremely good. The idle package power on this thing averages like under 1W even without efficiency cores [image]

Awesome complete chart of Apple Silicon chip performance by @SimeonNikolov! Crazy to see how the new M5 Pro matches the multi-core performance of the M3 Ultra. Can't believe THAT much power is going into a 14" MacBook Pro! Full Link to site: https://laptopmedia.com/... [image]

So I also got a Studio Display XDR and this thing is gorgeous. Speakers are amazing, camera is great, I really like it. [video]

Studio Display XDR is amazing I've been digging it, the video I just recorded on it is uploading (twitter us slow) [image]

NEW VIDEO - This is what 2000 local dimming zones (Studio Display XDR) vs 576 (Pro Display XDR) looks like. Mini LED ftw Full review: https://www.youtube.com/... [video]

I may never financially recover from this 🥲 Studio Display XDR MacBook Pro M5 Max [image]

Only with Apple is the new MacBook Pro lasting an extra 26 minutes - after a year and a half - considered an “astonishing” upgrade.

We tested the iPhone 17e, and it's an even better budget iPhone thanks to more storage, faster performance, and a smarter camera https://www.techradar.com/...

It's a true workstation in a notebook. The efficiency story and the way power is managed for not just the S and P cores but also the CPU/NPU tile and the GPU tile is impressive.

MLX benchmarks are in and I did not expect these results. the M5 Max blows the M3 Ultra out of the water, despite having more GPU cores and higher memory bandwidth. Compute-bound prefill is much faster (up to 2x) thanks to the new M5 Neural Accelerators, but also memory-bound [im…
@ronaldmannak Ronald Mannak on x
Tl;DR: Time to first token, where GPU speed matters most, is 2.5× faster on the M5 Max than on the M4 Max! It's also 1.5× faster than the M3 Ultra in llama.cpp testing, though not in MLX. I assume llama.cpp is tapping into the new Neural Accelerators. Now I really want to see

Here's my M5 Max report, it's a wonderful chip. The idle is lower than M4 Max while the peak performance is even higher. AI performance is, as you would expect, very very good. I think this is the best laptop SoC on the market, which is no surprise. https://creativestrategies.com…
