How to Read a PC Spec Sheet Without Being Fooled

Product pages are designed to impress. Learning a handful of terms lets you see past the marketing and compare machines fairly.

Processor (CPU)

Look at the product family and generation, not only the speed number. A newer mid-range processor often beats an older high-end one while using less power. The number of cores matters for multitasking and creative work, but everyday browsing rarely needs more than a modest count.

Memory (RAM)

Check both the amount and whether it can be expanded. Sixteen gigabytes is a comfortable target for most people today. Eight is workable if your habits are light.

Storage

Make sure it says solid state (SSD). A listing that only states capacity, with no type, may be using a slower drive. Size matters, but speed shapes how fast the computer feels.

Display

Ignore the word "HD" on its own, since it can mean a very low resolution. Look for 1920 x 1080 as a minimum, and note brightness in nits. Around 300 nits is acceptable indoors, and higher is better near windows.

Graphics

"Integrated" graphics are built into the processor and are fine for office work and video. "Dedicated" graphics are a separate chip, needed for gaming and serious design work.

Battery claims

Hours shown by makers come from light, ideal tests. Expect noticeably less during real use, and read independent reviews that run realistic tasks.

Small print worth finding

• Warranty length and what it covers.
• Whether the operating system is included.
• Port selection.
• Weight, for laptops you carry.

The comparison habit

Put two or three candidates side by side in a simple table of price, memory, storage, screen and warranty. Differences you can see in black and white are easier to judge than a page of adjectives.
