Depth from the back cover to the closed door. Add installation-manual clearance for hoses and ventilation.

When it matters: When this specification affects your everyday use, installation or total ownership cost.

Trade-off: A single number or marketing name cannot establish overall product quality.

Ask before buying: What are the test conditions, restrictions and exact model-specific details in the manufacturer manual?

Steam is available on supported programmes. It does not mean every cycle uses steam or that all fabrics are suitable.

When it matters: Consider it for the specific supported care programmes you will use.

Trade-off: Some cycles take longer or use more energy; claims vary by programme.

Ask before buying: What test supports the hygiene claim and what fabrics are excluded?

App-connected features require compatible network and account setup. Confirm remote-start conditions in the manual.

LG’s adaptive washing feature. On these two models, AI DD applies to Cotton, Mixed Fabric and Easy Care cycles only. Follow care labels and load limits; an AI label alone does not prove better cleaning.

When it matters: Relevant if supported automatic cycles match the fabrics you wash.

Trade-off: Automatic sensing does not remove sorting, load limits or care-label instructions.

Ask before buying: Which cycles and load sizes support sensing, and what is the fallback for delicate fabrics?

Heat removed by the AC, not the electrical power it draws. Match this to a room load assessment.

When it matters: When this specification affects your everyday use, installation or total ownership cost.

Trade-off: A single number or marketing name cannot establish overall product quality.

A seasonal cooling-efficiency ratio. Higher indicates more cooling per unit of electricity under comparable rating conditions.

When it matters: Especially useful for frequently used ACs, after confirming adequate cooling capacity.

Trade-off: A higher rating can cost more upfront; savings depend on use and tariff.

Ask before buying: Are both labels valid for the same rating period and comparable capacities?

A standardised rating figure, not your predicted bill. Weather, use and settings affect actual consumption.

Trade-off: A single number or marketing name cannot establish overall product quality.

Ask before buying: What are the test conditions, restrictions and exact model-specific details in the manufacturer manual?

Efficiency rating reported by the manufacturer. Compare the same label period and product category; this catalog has not checked registry validity.

How often the screen refreshes. Higher rates can make scrolling smoother; content and settings matter.

When it matters: Useful for scrolling, gaming and pen interaction when apps support it.

Trade-off: Higher refresh can use more power; adaptive behaviour matters.

Ask before buying: Does my game run at the advertised refresh rate and resolution?

The chip family. Names or core counts alone do not establish performance across brands.

Lens choices affect framing. Megapixels alone do not determine photo quality; compare samples.

When it matters: Choose lens coverage for portraits, distant subjects or wide scenes.

Trade-off: Sensor quality, processing and stabilisation matter more than megapixels alone.

Ask before buying: Can I compare unedited indoor, moving-subject and low-light samples?

Device mass without accessories. Try it in hand if comfort is important.

Ask before buying: What are the test conditions, restrictions and exact model-specific details in the manufacturer manual?

Working space for active applications. Unified memory is shared by the processor and graphics.

When it matters: Prioritise for many active apps, creative work or large local models.

Trade-off: Memory may be non-upgradeable; more memory cannot fix every processor bottleneck.

Ask before buying: Can it be upgraded later, and how much does my real workload use?

Graphics core count within this chip family; not a comparable speed score across architectures.

The cooling system’s motor technology. An inverter adjusts speed; the label alone does not prove lower bills.

When it matters: Consider alongside efficiency, noise, temperature control and service.

Trade-off: A compressor warranty may exclude labour, refrigerant and electronics.

Ask before buying: What exactly is covered, for how long, and who services my postcode?

AI processing performed on your device for supported tasks. A product can combine local and cloud processing.

When it matters: Useful for supported tasks where latency, offline access or keeping input local matters.

Trade-off: Models are limited by device memory and power; some features still use cloud services.

Ask before buying: Which exact task works in airplane mode, in my language, without a subscription?

A smart-home interoperability standard for supported devices and controllers.

When it matters: Useful when connecting supported devices across compatible home ecosystems.

Trade-off: Certification does not guarantee every advanced feature works in every controller.

Ask before buying: Which Matter version, device features and controller versions are supported?

A processor block designed to accelerate supported neural-network workloads.

When it matters: Useful for software that actually uses its neural-processing hardware.

Trade-off: Peak TOPS is not an app performance benchmark and varies with precision.

Ask before buying: Which of my apps uses the NPU and how does it perform on my workload?
