How much faster is each new laptop generation?

Typically a modest single-digit to low double-digit improvement in most workloads, with occasional larger steps when an architecture or a cooling design changes. Because the discount on the superseded model is often much larger than that gap, last year's machine usually wins on value.

When is the best time to buy a laptop?

Shortly after a new generation is announced, when the previous model is discounted but still current enough to have full support and parts. Major retail sale periods work too, though the supersession discount is usually deeper and more predictable.

Is a two-year-old laptop model still worth buying new?

Sometimes, if the discount is large and the model had no known faults, but you are giving up two years of support runway and driver updates for a machine that has not fallen much further in price. The just-superseded model is nearly always the better balance.

Problems · Before you buy

Is it worth buying last year's laptop model?

Usually yes. Year-on-year performance gains in laptops are typically modest, while the discount on the previous model once it is superseded is often substantial. For most buyers that trade favours the older machine comfortably.

The three cases where it does not: when the new generation changed something structural rather than incremental, when the older model has a documented fault, and when buying the old one shortens your support and warranty runway meaningfully.

First, notice when it happens

From the first minute

Burst performance between adjacent generations is usually close enough that nobody would notice the difference blind.

Only after minutes of use

Sustained performance sometimes changes more between generations than peak does, because cooling redesigns show up under load rather than in benchmarks.

The causes, ranked

1. Incremental generational gains

most common

How to confirm it

Compare the two models' measured figures rather than their marketing. Single-digit percentage differences are common and are not worth a large premium.

The fix

Buy the older one and put the saving into memory or storage, which are soldered and therefore matter far more over the machine's life.

2. The discount being the real story

most common

How to confirm it

Superseded models fall in price sharply, particularly at the end of a retail cycle, while their capability has not changed at all.

The fix

Buy at the point of supersession rather than at launch. This is the single most reliable way to buy more laptop for the same money.

3. A structural change worth waiting for

common

How to confirm it

Occasionally a generation brings a genuine step: a redesigned cooling system, a different memory architecture, a much better screen, or a major efficiency gain.

The fix

Read what actually changed. When the change is structural, the new model is worth its price, and when it is a clock speed bump it is not.

4. A documented fault on the older model

common

How to confirm it

Community reports of a specific problem on that model: a keyboard generation, a thermal design flaw, a failing port.

The fix

Search the exact model before buying. A discount on a machine with a known defect is not a discount.

5. Support and warranty runway

common

How to confirm it

An older model is a year further through its driver support, its parts availability and its operating system compatibility.

The fix

For a machine you expect to keep six years, this matters. For a three-year horizon it usually does not.

6. Old stock that is older than it looks

occasional

How to confirm it

A machine that is two or three generations old still on sale at a small discount, which is a different proposition from last year's model.

The fix

Check the actual release date rather than the shop's shelf. The best value is the model just superseded, not the one nobody bought.

Measure it instead of guessing

If both are in front of you, run the same sustained test on each and compare the settled levels. That comparison is far more honest than a specification table, and it occasionally shows that the new model's redesigned cooling is the real upgrade rather than its processor.
