What reviewers said about theiMac (Retina 5K, 27-inch, 2017)
1 review of this exact model; 1 of a sibling configuration (same chassis; a different chip or size, or the review does not state this Mac’s base chip with its CPU and GPU core counts), used for design topics only. Quotes are short, word for word, and each links to the article it came from. Every one was checked against that article on . MacIQ gives no score and no stars, and averages nothing.
Only 2 reviews could be used for this Mac, so this page is not offered to search engines. Nothing is added to make up the number.
A count of the reviews we quote on this page that have a quote on each topic, from the findings shown below. A review may say more on a topic than we quote, so it counts what is quoted here, not everything each review covers, and it says how often a topic is quoted, not what was said about it. Battery, performance and heat are counted over the 1 review of this exact model.

Where reviewers and Apple differ
A reviewer’s own figure beside Apple’s claim, each as its author printed it. Where the tests are of the same kind (web browsing, or the movie playback or streaming test Apple names, and only where the reviewer says so) that is said; where they are not, the two are shown and not compared. A video loop that the reviewer does not describe as Apple’s test, or ran from a stored or downloaded file, is shown, not compared. Figures are never ranked, subtracted or pooled across methods.
514cd/m2 maximum brightness, from “putting it through the X-Rite i1Display Pro calibrator”. Expert Reviews
The reviews
Newest first, in the order of the date each article prints (which may be an update date, not a first-publication date). Each quote links to its article; the date is the one the article prints, labelled as the article labels it. “Published” and “Updated” appear only where the article prints that word beside the date; “Dated” means the article prints that date with no label, so the date itself does not say whether it is the first publication or an update. A later update that an article mentions only in an editor’s note is not used as its date.
