Surface Laptop Ultra vs 14-Inch MacBook Pro M5: Battery, Display and Local AI Compared

The short version is that the MacBook wins on weight, battery life and Adobe RGB coverage. The Surface wins on multi-core CPU throughput (barely), port variety and on-device AI positioning. Several details in the comparison need careful handling before you spend $2,600 or more.

What was actually compared​

ITPro's comparison pits Microsoft's Surface Laptop Ultra against the base 14-inch MacBook Pro with the M5 chip. It is a roundup of the outlet's two separate reviews, not a new round of testing.

Two configuration caveats matter:

• The Surface was tested as a 64GB / 1TB unit. Microsoft's own product page says the machine starts at 24GB of unified memory and 512GB of storage, but I can only cite Microsoft's description for that. Microsoft says it scales to 128GB of memory and 2TB of SSD storage.
• The MacBook is the entry-level M5, not the top of Apple's range. Apple's support page lists 14-inch and 16-inch models with M5 Pro or M5 Max chips, all introduced in 2026. The base 14-inch M5 is a 2025 model.

That second point changes the framing. Gizmodo's review of the Surface says that if you wondered whether RTX Spark could beat an M5 Max MacBook Pro, you can keep dreaming, because the M5 Max claims top spot with close to 44% better Geekbench 7 multi-core performance. Against Apple's base chip the Surface looks competitive. Against Apple's high-end chips it looks different.

Hardware at a glance​

ITPro lists the Surface's graphics as a 5,120-core Blackwell GPU in the comparison. Its separate Surface review mentions a 6,144-core GPU for the same chip. Microsoft's materials refer to a 6,144-core N1X configuration in its battery testing footnotes. Reviewers' configurations differ, so verify the exact GPU core count of the unit you're ordering.

Design and portability​

The Surface is 450g heavier and 3.7mm thicker than the 14-inch MacBook. ITPro's reviewer says he carried both between desk and meeting room and on a rucksack commute, and found the Surface "noticeably heavy". The Surface review goes further and calls it basically a desktop, brick charger included. Treat the 450g figure as the hard fact and the commute experience as opinion.

The Surface's bulk buys connectivity. Microsoft's spec page lists three USB4 USB-C ports, one USB-A port, HDMI, a headphone jack and an SD card reader. Anyone who still lives with USB-A thumb drives, dongles or legacy peripherals will notice. The MacBook has no USB-A, but it does have three Thunderbolt 4 ports plus HDMI and SDXC.

One structural difference is that the Surface is available only in 15 inches, while Apple offers 14 and 16. ITPro notes that even the 16-inch MacBook is 16.7mm thick, thinner than the Surface.

Display: the Adobe RGB gap​

ITPro measured both panels with DisplayCal and a colorimeter:

• sRGB: MacBook 99.7%, Surface 94.7%.
• Adobe RGB: MacBook 85.8%, Surface 65.6%.

ITPro says it wants roughly 70% Adobe RGB or better for serious photo editing or print-grade colour work. The Surface falls under that bar. That matters if you do print work.

The Surface isn't a dim panel. ITPro's separate review recorded a peak of 969.95 cd/m² with HDR active, and Microsoft markets up to 2,000 nits peak HDR brightness (measured on a 10% window). Microsoft also advertises 100% DCI-P3. Those are manufacturer claims, not independently verified here, and the sRGB and Adobe RGB measurements are different metrics.

CPU: a split decision, with a benchmark asterisk​

ITPro reports these CPU numbers:

The comparison labels these as Geekbench 6. ITPro's standalone Surface review, though, attributes the Surface scores to Geekbench 7. Its MacBook review lists 4,248 and 17,600 as Geekbench 6 results.

Geekbench versions are not directly comparable. If the table mixes versions, the single-core gap may be exaggerated or distorted. ITPro itself is inconsistent on the MacBook single-core figure, citing 4,284 in the Surface review and 4,248 elsewhere, which looks like a typo.

Other outlets' Surface results vary quite a bit:

• Tom's Hardware reported Geekbench 6 scores of 3,151 single-core and 20,203 multi-core.
• PC World recorded Geekbench 7 scores on battery of 1,899 single-core and 17,328 multi-core, and it said it used Geekbench 6 for comparison charts.
• Windows Central reported Geekbench 7 scores of 2,718 single-core and 23,571 multi-core on a 128GB configuration.

The practical reading is that the Surface's multi-core edge over the base M5 looks small to moderate, and its single-core score is the weak spot in ITPro's results. Other reviewers saw higher single-core scores in different configurations and power modes. Single-core speed drives everyday responsiveness, so it's the number to watch if you mostly run office and browser workloads.

Battery: the clearest win​

ITPro's looped-video test uses VLC, 170 cd/m² brightness and airplane mode.

• MacBook Pro M5: 20 hours 32 minutes (ITPro's earlier MacBook review gave 20h31).
• Surface Laptop Ultra: 12 hours 41 minutes, and under 10 hours with HDR enabled.

Microsoft's own estimates are up to 15 hours of local video and 12 hours of active web browsing. Microsoft's testing used 150 nits brightness on preproduction hardware. Apple's own figures for the 14-inch M5 are up to 24 hours of video streaming and 16 hours of wireless web. Vendor figures and ITPro's test aren't comparable with each other, but in both cases the MacBook's number is higher.

Other reviewers saw lower Surface results under different workloads:

• PC World measured 7 hours 57 minutes streaming 4K video.
• It also measured 10 hours 3 minutes on a simulated office-app test.
• Gizmodo said GPU-heavy tasks such as AI and gaming last between two and three hours.

A video-loop test is a best-case scenario. Real battery life on a machine built for local AI will depend heavily on how hard you push the GPU.

The Windows-on-Arm question​

This is the part the comparison table can't show. Microsoft says the Surface Laptop Ultra runs Windows 11 on an Arm-based platform. It also says many popular apps run natively on Arm, and that apps not built for Arm can run through Prism, Windows' built-in emulator. Microsoft explicitly advises checking compatibility if you depend on specialized hardware drivers, plug-ins or older utilities.

For IT admins, that means a pilot before any fleet purchase:

1. List the apps, plug-ins and peripheral drivers your target users rely on.
2. Check whether each has a native Arm64 build or an acceptable emulation story.
3. Test VPN clients, endpoint security agents and anything that installs kernel drivers, since those are common failure points on Arm.
4. Confirm CUDA-dependent tools work in your actual workflow before treating the GPU as a selling point.

That checklist is my own general guidance, not something from Microsoft's page or ITPro. The reviews also show the platform is still maturing. Tom's Hardware's subtitle says Windows 11 is still waiting for more features that take advantage of the hardware. Microsoft also notes the Surface doesn't include a Microsoft Office license.

Local AI: where the Surface makes its case​

Microsoft says RTX Spark offers CUDA support and a shared unified-memory pool for the CPU, graphics and AI acceleration. It also says local agent workflows can use models up to 120B parameters. Microsoft's own announcement attributes its headline AI-compute figure to theoretical FP4 performance with sparsity. That is a peak-throughput number, not a promise of real-world speed.

For something measured, StorageReview's reviewed unit ran with 128GB of memory split 64/64 between system and GPU. Its headline says it ran a 35B-parameter coding agent at 89 tokens per second, "with one major caveat". I can't verify the caveat from the excerpt I have.

On a base M5 MacBook with up to 32GB of memory, large local models are a harder fit. That's reasoning from the specs, not a tested result. If your work involves local LLMs, memory capacity and CUDA compatibility matter more than Geekbench single-core.

Price​

ITPro's Surface review says pricing starts at $2,599.99 and climbs to almost $6,000 in the US. Its MacBook review lists the 14-inch M5 starting at $1,599 at launch. Those are ITPro's reported prices, and configurations differ so much that I wouldn't treat this as a like-for-like comparison. The tested 64GB Surface is far above the Surface base price, while a 32GB MacBook would cost more than the base $1,599.

Verdict: what the evidence supports​

Pick the MacBook Pro M5 if:

• You carry the laptop daily and weight matters.
• You work away from a power outlet for long stretches.
• You do color-critical or print-oriented photo work, given the Adobe RGB gap.
• Your software is macOS-first.

Pick the Surface Laptop Ultra if:

• You need Windows 11 and CUDA-based AI development in one machine.
• You want a bigger touchscreen and a wider built-in port selection.
• Your workloads run well on Arm, natively or through emulation, and you can tolerate a heavy machine that spends much of its life on a charger.

ITPro's own verdict says the MacBook is the better laptop on battery and display, and that the Surface's multithreaded advantage is "not by much". That's a fair summary, with the caveats above. It compares a base M5 against a high-memory Surface, mixes benchmark labels, and doesn't test the M5 Pro and M5 Max machines that are Apple's real answer to the Surface's workstation ambitions.

The Surface Laptop Ultra is a meaningful first for Microsoft: a Windows laptop with a full CUDA-capable Nvidia platform. But the early reviews don't support the "MacBook killer" label. For now it looks like a different tool for a narrower audience.
