Lenovo G405s review

Lenovo G405s — a 2013 entry APU with a vestigial dGPU

The Lenovo G405s is a 2013 budget 14-inch built on AMD's A8-5550M — a Richland-era quad-core APU from the entry tier — paired with a Radeon HD 8550M entry discrete GPU. At $149 it sits 40% below the general-laptop median of $248. The measured profile: CPU score 0 (a data-floor reading), performance index 0.685, graphics 1.37 — with the game bars delivering the categorical verdict.

What the scores and bars say

The CPU floor reading places the A8-5550M below the scoring model's distinction threshold — commodity entry silicon from 2013. The HD 8550M was among the weakest discrete GPUs ever shipped, and it shows: Grand Theft Auto V, Far Cry 5 and Battlefield 5 all fail their minimum bars. The presence of a discrete GPU part is a technicality, not a capability — the honest reading treats this as an iGPU-class machine of the floor tier.

The honest framing

Performance 0.685 against a 43 median is among the lowest non-zero readings in the catalog. The G405s chassis was Lenovo's entry family — commodity build, no distinction. The one argument for this listing is its $149 price, and the band offers faster machines both cheaper and at the same money, which closes the argument the same way it does for this machine's APU siblings.

Price trajectory

From an original $900 to $149 today at 6.76% per year, with a further projection to $130 (a 13.06% drop) over two years. Twelve years have flattened the curve; remaining value tracks unit condition alone.

Where it sits against peers

The pricier neighbor is the Pavilion dv7 6b55sg ($157); cheaper options are the Pavilion dv6 ($137) and Inspiron 15-3552 ($127). Sideways sit the Pavilion g7-2222sg ($147) and IdeaPad G710 ($145). Every rival in the band measures faster; the dv7 at least offers the 17-inch screen for its premium.

Bottom line

A floor-tier 2013 APU machine whose discrete-GPU badge does not survive the measured bars — every game test fails. Recommended only where price alone governs; the same-band machines at $127-147 deliver more capability for the same or less.
