In what is a testament to Apple's penchant for optimizing its products to the umpteenth extent, the iPhone 17 models show the least performance variation between the early review units and their mass production counterparts, with many Chinese OEMs predictably faring quite poorly against Apple's benchmark consistency.
Apple's iPhone 17 production models show admirable performance consistency against early review units
As per a recent test that compared various flagships based on the performance of early review units with their production-ready counterparts, Apple's iPhone 17 lineup showed the lowest variance overall, with the iPhone 17 Pro and Pro Max going so far as to register an improvement between review and production units.
Only the base iPhone 17 showed a slight deterioration, and that too of just 0.2fps. In contrast, Oppo Find X9 Pro showed a deterioration of 6.1fps.
Do note that Samsung's phones were not included in this test due to a lower market share in China. This suggests that Chinese OEMs heavily optimize their review units, possibly in a bid to influence those reviews. However, the same optimizations then fail to port over to mass production units, creating a discrepancy that might incur legal liabilities.
The premise for this test is pretty simple: if customers' buying decisions are being influenced by early reviews, the smartphone that they do end up buying should also match the performance of those review units. In the case of Chinese OEMs, however, users typically experience degraded performance.
Apple, however, does manage to exhibit admirable performance consistency, which suggests that the Cupertino giant either does not apply any special optimizations to its review units or applies them equally to all units.
