What changed between M3 Pro and M4 Pro

The M4 Pro is Apple’s 3nm process (technically TSMC N3E, the same node as the M3 Pro but with refinements). The headline improvements are in the CPU: Apple claims 25% faster single-threaded performance and up to 40% faster multi-core. In our testing with a cross-compilation workload and a Final Cut export, the gap was real — closer to 20% on mixed tasks, which still matters if you’re doing this all day.

The GPU sees a bigger jump in certain workloads. The 20-core GPU in the M4 Pro handles GPU-accelerated ML inference noticeably faster, which matters if you’re running local LLM inference via tools like llama.cpp or Ollama. The M3 Pro’s 18-core GPU was already capable, but the memory bandwidth increase in M4 Pro (273 GB/s vs 150 GB/s) makes a measurable difference for large model weights.

Battery life: the underrated story

Apple’s claimed 22 hours of video playback is, as always, aspirational. In mixed real-world use with 8–10 browser tabs, an IDE, and Slack running, we measured 14–16 hours. That’s still more than a full workday for most people. The M3 Pro in the same chassis managed 11–13 hours under a comparable load. The additional 2–3 hours is meaningful for a travel day or a day of meetings where you move around.

Who should upgrade

The M4 Pro upgrade makes sense if: you’re running sustained compute workloads (video editing, 3D rendering, ML inference) and time-to-completion matters in dollars. It makes sense if you’re on an Intel MacBook Pro from 2019–2021 — the performance gap is enormous and you’ll recoup time rapidly. It makes sense if you regularly use the machine without power for more than 10 hours.

It does not make sense if you’re on an M2 Pro or M3 Pro, unless your specific workflow is GPU-memory-bound or your work is billable by the hour in a way that 25% faster compilation translates directly to income.

The bottom line

The MacBook Pro 14″ M4 Pro is the best laptop Apple has made. It is not a dramatic step change from the M3 Pro, which was already very good. If you’re deciding between M3 Pro (available at discount) and M4 Pro (full price), the M4 Pro is worth the premium for heavy creative or computational users. For everyone else, the M3 Pro is still an excellent machine at a lower price.

Noise cancellation

The Sony gets quieter. On a London Underground train, the XM6 reduces the broadband noise floor to the point where conversation is possible at a normal indoor voice. The Bose QC Ultra doesn’t quite reach that floor — the mid-frequency range (speech, HVAC hum) is slightly more present. However, the Sony’s ANC introduces more artefacts on transient sounds like door slams; the Bose handles those more gracefully. If you’re measuring quietude in absolute terms, Sony. If you’re measuring naturalness of ANC behaviour, Bose.

Sound quality

This is where the comparison gets genuinely interesting. Sony’s XM line has always had a “Sony sound” — warm, slightly enhanced bass, slightly recessed upper mids. The XM6 maintains this but it’s more balanced than the XM5 was. The Bose QC Ultra is more neutral — closer to a studio monitor in its tonal balance. For pop, electronic, and hip-hop, most people in our informal test preferred the Sony. For acoustic, jazz, and classical, the majority preferred Bose. Neither is wrong.

The Bose Immersive Audio spatial mode is worth noting. With compatible content, it creates a convincing stereo widening effect. It’s not a substitute for proper binaural recording, but it makes standard stereo mixes feel less “inside the head.” Sony has a similar feature (360 Reality Audio) that requires different source material.

Comfort for long sessions

The Bose is more comfortable over 4+ hours for most of our testers. The ear cushions are deeper and the clamping force is lighter. The Sony’s fit is more secure — which matters for commuting and exercise — but for a 6-hour flight, the Bose wins the endurance test. This is the most subjective dimension and depends heavily on head shape.

Build and controls

Both are premium-feeling builds. The Sony folds flat into a compact case; the Bose does not fold as compactly but its case is slimmer. Sony uses a touch-sensitive cup for playback controls; Bose uses physical buttons. We prefer the Bose approach — buttons work with gloves and are reliable without looking at the headphone.

Verdict

Sony WH-1000XM6 for: commuters, those who want maximum quietude, Sony ecosystem (LDAC Android users). Bose QC Ultra for: long-haul travel, neutral sound preference, more natural ANC behaviour. Both are excellent. Neither is a bad choice at their respective prices.

The spec numbers that actually matter

USB-C cables come in several performance tiers: USB 2.0 (480 Mbps, 60W max), USB 3.2 Gen 1 (5 Gbps, 100W), USB 3.2 Gen 2 (10 Gbps, 100W), USB4 Gen 2×2 (20 Gbps, 240W), and USB4 Gen 3×2 / Thunderbolt 4 (40 Gbps, 100W). The cable included with your iPhone 16 is USB 2.0 — it charges fine but transfers data at 480 Mbps, which means a 60 GB video file takes about 17 minutes instead of 8 seconds via Thunderbolt.

Power delivery follows similar logic. The old 60W standard covers most phones and small laptops. 100W covers 13-inch MacBook Pro. 140W covers 16-inch MacBook Pro. 240W (USB PD 3.1) covers gaming laptops. Higher wattage cables look identical to lower ones — the difference is inside.

The cables we actually use

For daily MacBook charging: Anker 140W USB-C cable (2m). Thick, reliable, carries full power to any USB-C laptop. We’ve used the same one for 18 months without issues.

For iPhone to Mac transfers: Apple’s 1m USB-C cable (came with iPhone 15/16) handles USB 3 speeds from the Pro models. If you have an iPhone 16 standard, upgrade this cable — the stock cable is USB 2.

For desk to monitor: Thunderbolt 4 cable (0.8m). Thunderbolt 4 carries 40 Gbps data, 100W power, and video signal for up to 8K displays in a single cable. The CalDigit 0.8m Thunderbolt 4 cable is our go-to.

For travel: a 1m USB-C to USB-C rated for at least USB 3.2 Gen 2 and 100W charging. Most Anker and Belkin options in this category are reliable.

What to look for on the packaging

Look for the USB logo with the specific generation written underneath. “USB4” or “Thunderbolt 4” on the packaging means the cable supports 40 Gbps. “USB 3.2 Gen 2” means 10 Gbps. “USB 2.0” means the cable is for charging and audio only. A wattage rating (100W, 140W, 240W) tells you what power delivery it handles. A cable with no spec labelling beyond “USB-C” is almost always USB 2.0 quality.

The post USB-C is finally everywhere — here’s the cable drawer you actually need appeared first on Voltacore.

What’s actually improving each generation

Battery life gets meaningfully better over 3–4 generation cycles. The move from 18-hour to 36-hour (low-power GPS) in Apple Watch Series 10 is a genuine lifestyle change. Processor speed improvements are real but rarely surface in health monitoring — your heart rate sensor doesn’t need a faster chip. Display quality improvements (LTPO, higher nit count) matter for outdoor readability. New health sensors matter infrequently — blood oxygen came with Series 6 but wasn’t actionable until software caught up in Series 9. Sleep apnea detection in Series 10 is the first sensor addition in four years that changes behavior for a meaningful subset of users.

The upgrade cost isn’t just money

Each watch upgrade generates e-waste — the old device, its band, its charger. Apple doesn’t publish recycling rates for Watch trade-ins. The environmental cost of a new wearable (rare-earth metals, shipping, packaging) is not zero, and it’s worth weighing against a feature set that improved by 8% on the axis you care about.

Which scenarios justify an upgrade

Moving from a first or second-generation watch to a current model: the sensor accuracy, battery life, and feature set gap is large enough to meaningfully change health monitoring utility. Moving from a non-GPS watch to a GPS-capable one: the running and routing capabilities change how you train. Moving from a watch that no longer receives software updates: you’re giving up security patches and new features simultaneously.

The right approach

Buy a watch rated for at least 5 years of software support. Garmin provides this clearly (most models get 5+ years of map and software updates). Apple Watch receives software updates for about 5–6 years. Set a replacement threshold: “I’ll upgrade when battery health drops below 75% or when a feature I use daily is removed from my model.” That’s a rational upgrade cycle, not a calendar-based one.

The core principle: fewer cables means fewer cable decisions

The reason most desks look chaotic isn’t budget — it’s the number of cables. A laptop charger, a monitor cable, a USB hub, a keyboard cable, a mouse receiver, a phone charger, earbuds case, and occasional external SSD adds up to eight potential cable touchpoints before you’ve added anything optional. The goal isn’t to hide cables; it’s to need fewer of them.

The $300 build

Anker Prime 100W GaN Charger ($69 on sale): One 3-port adapter on your desk powers laptop (100W), phone (27W), and any third device simultaneously. Replaces the laptop brick and the phone charger separately.

Logitech MX Master 3S ($79 on sale): Logi Bolt receiver hides in a laptop USB-A port. Bluetooth backup connects to a second device. No mouse pad required — tracks on glass. Scroll wheel makes navigating long documents dramatically faster. Ergonomic design reduces wrist fatigue in longer sessions.

Belkin BoostCharge 3-in-1 Qi2 ($149): iPhone + AirPods + Apple Watch all from one USB-C cable. Replace three charging cables on your nightstand with one vertical stand on your desk or beside your bed.

Total: $297. That covers a charger that handles everything, a mouse that works wirelessly across multiple devices, and a charging stand that eliminates three separate chargers. The desk has three cable footprints instead of eight: one laptop cable, one monitor cable (if used), and one charging stand cable.

What to add when the budget grows

A Thunderbolt 4 dock like the CalDigit TS4 reduces to a single cable for everything. A cable spine or raceway channels remaining wires together. A monitor arm frees desk surface and eliminates monitor stand footprint. These are refinements on a setup that already works well at $300.

What genuinely improved

The chassis is the most meaningful change. The S25 Ultra is thinner (0.34 in vs 0.35 in), lighter (0.46 lbs vs 0.48 lbs), and the corner radius matches the rest of the Galaxy line, which makes one-handed operation meaningfully more comfortable on a 6.9-inch phone. Snapdragon 8 Elite is a real performance upgrade — Samsung’s fastest Galaxy phone, by some margin — and the thermal management is improved enough that sustained video recording doesn’t cause the quality throttling that affected some S24 Ultra units.

Galaxy AI in practice

AI features are where Samsung has invested most heavily. Circle to Search works reliably and is genuinely useful — drawing a circle around text or an object in any app and getting a contextual search result is faster than the alternative. Note Assist summarises Samsung Notes entries with reasonable accuracy. Interpreter mode handles simultaneous translation in conversation at speeds that are practically useful. These aren’t gimmicks; they change real workflows.

The camera reality

The 200MP main sensor captures detail that crops usefully to smaller sizes, but Samsung’s processing makes aggressive decisions about colour, sharpening, and HDR composition that aren’t universally better. In direct A/B tests against the Google Pixel 9 Pro, the Samsung produces images that look more impressive in a quick scroll and less accurate when you examine fine detail. Neither approach is objectively correct, but users who care about natural colour rendition should be aware of the trade-off.

Space Zoom at 30× is genuinely sharp. Space Zoom at 100× is useful for identifying something at distance; the AI upscaling is apparent at 100% view and the photos are not shareable at that magnification in most cases.

The S Pen and seven-year commitment

The integrated S Pen remains the defining feature of the Ultra line for the users who need it. Handwriting, document annotation, and screen-off notes are fluid and accurate. Samsung’s seven-year OS update commitment is the best in Android and represents meaningful long-term value at this price point. If you’re choosing between an S25 Ultra and an iPhone 16 Pro and the S Pen matters to you, the Ultra wins that comparison decisively.

Verdict

The Galaxy S25 Ultra is Samsung’s best phone. It is a refinement of the S24 Ultra rather than a reinvention. If you own an S24 Ultra, skip it. If you own an S23 Ultra or older, the performance, camera, and chassis improvements justify the upgrade. The camera year Samsung promised is still ahead of us.

1. Anker Prime 100W GaN Charger

This replaced three different chargers for most of the customers who bought it. 100W GaN in a 5.3-ounce body that handles MacBook Pro, iPhone, and a third device simultaneously. The dynamic port allocation means you don’t have to think about which device goes in which port — it adjusts automatically. At $69 (usually $89), it’s the highest-value density item we carry. Customers send us photos of the charger collection it replaced.

2. Logitech MX Master 3S

The MagSpeed scroll wheel converts people. We’ve had customers email us saying they bought the mouse on a recommendation, tried it for three days, and then bought a second one for their home office. The near-silent clicks and three-device pairing with instant switch make it a genuinely different tool from a standard scroll wheel mouse. It’s the kind of product that changes your computing workflow in a way that’s difficult to explain until you’ve used it.

3. Apple AirPods Pro 2

The best earbuds for iPhone users, and the firmware updates over the past year have made them meaningfully better without new hardware. Adaptive Audio is the feature customers cite most: the headphones adjust to the environment automatically in a way that makes switching modes manually feel antiquated. They work especially well for city commuters who need to be partially aware of their surroundings without constantly toggling ANC.

4. CalDigit TS4 Thunderbolt 4 Dock

This one sells in two clusters: first-time home office setups and people who spent money on a cheaper hub and upgraded. The TS4 is the dock we recommend to anyone working from a laptop full-time with external displays. One cable, 18 ports, 98W to the laptop, and it works the same way on day 400 as on day 1. The build quality justifies the price.

5. Belkin BoostCharge Pro 3-in-1 Qi2

The cleanest solution to Apple’s three-cable bedside charging problem. iPhone at 15W (Qi2 magnetic), Apple Watch on a dedicated fast-charge pad, and AirPods on the third pad. Everything charged from one cable, no cable hunting in the dark. It works as described without caveats, and the weighted base doesn’t tip when you grab your phone without looking. Sometimes the best product is the one that does exactly what it claims, reliably, for years.
