LG Gram 16 (16Z90Q) review: A big, almost perfect ultrabook

The Gram 16 (16Z90Q) that LG gives us has 16GB of RAM and a 1TB SSD. The processor is identical on all Gram 16s; It’s an Intel Core i7-1260P. The latter is equipped with a hybrid Alder Lake architecture and consists of 4 overlapping cores, called high-performance, and 8 so-called effective cores. Its power envelope is 28 watts, which puts it halfway between the U series (15 watts) and the H series (45 watts).

The LG Gram 16 and Core i7-1260P both get a performance index of “only” 93 according to our various tests. It is thus closer to the Samsung Book2 15 (Core i7-1255U 15W with a benchmark of 89) than it is to the Samsung Book2 Pro (a benchmark of 115 with the same Core i7-1260P as the Gram 16).

The explanation can be found on the side of the settings that LG applies to the Core i7-1260P. Thus, during encoding of just over 20 minutes, P-Cores run at an average of 1.24GHz and E-Cores at 1.11GHz, for an average power envelope of 12.7W, so Intel ensures that this processor should run at a minimum of 20W. LG may have voluntarily implemented a conservative setting to reduce consumption and thus promote cooling and quiet operation.

Unlike the processor, the SSD does not do half the actions and sends 6.4 GB / s in reading and 3.9 GB / s in writing (measured data); Enough to quietly consider large file transfers.
