Apple's unannounced M4 MacBook Air family is likely reaching market availability status at some point next month . Last December, slimline notebook enthusiasts started hearing about an updated lineup; macOS's Sequoia 15.2 update reportedly referenced upcoming MacBook Air M4 13-inch and 15-inch models. An early sample unit—named "Mac16,12"—has participated in a Geekbench 6.4.0 (macOS AArch64) gauntlet; results appeared online yesterday. The alleged "MacBook Air 13" candidate posted an overall Metal score of 54,806 , and an overall OpenCL tally of 36,305 . The two separate Geekbench Browser entries confirm that the sampled device makes use of a 10-core M4 processor , with Cluster 1 containing four performance cores. Cluster 2 consists of six power efficiency-oriented cores. Base frequency is listed at 4.41 GHz; reportedly the highest recorded for an M4 SoC. Said chip accessed 24 GB of unified memory, during its macOS 15.2 (Build 24C2101)-based test session.

Notebookcheck and Wccftech compared the aforementioned data points with slightly older M4-equipped hardware, including a premium model. Both outlets observed a "measly" five percent performance difference. Elaborating on their findings, Notebookcheck stated: "as always, we would recommend taking early benchmark results with a healthy amount of skepticism for the time being. With that being said, the MacBook Air 13 benchmarked falls about 5% short of the median Geekbench OpenCL and Geekbench Metal results we achieved so far when benchmarking the M4 versions of Apple's Mac Mini and MacBook Pro 14." The rumored next-gen MacBook Air is expected to operate with a fan-less cooling system—press outlets reckon that the MacBook Pro's air-cooled operation puts it at a slight advantage (in benchmarks).
