In iPhone6s and iPhone6s Plus, Apple uses both A9 chips manufactured by Samsung and TSMC. Conventionally, the A9 chip produced by Samsung uses a 14nm manufacturing process, and Samsung has mature OEM experience in Apple's A-series processors. Compared with TSMC, which uses 16nm, Samsung's version will have more advantages. . However, customers found in actual testing and use that these so-called advantages of Samsung are actually the same, and TSMC chips perform better than Samsung chips. Especially in the battery life test, the difference between the two is between 6% and 22%. The battery life of TSMC chips is far better than that of Samsung chips. Seeing these test results, customers who bought chips using TSMC may be happy for a while, while customers who bought chips using Samsung will not be happy. It’s true that some are happy and some are sad.

Private testing of TSMC’s version of the A9 chip was better than Samsung’s. Apple recently officially responded to the matter, saying that in tests in Apple’s labs, the difference in battery life was only 2%-3%. They have conducted internal testing and collected customer data to determine the performance differences between the two chips. "The Apple-designed A9 chip in iPhone 6s or iPhone 6s Plus is the world's most advanced smartphone chip. No matter which capacity version, color or model of iPhone 6s is used, every chip we use meets Apple's highest standards. Standard, with excellent performance and excellent battery life

Apple responded: There is not much difference between the two versions of the A9 chip

Previously, a customer found TSMC in the Geekbench 3 test. The battery life of the new version is about two hours longer than that of the Samsung version. Testers conducted multiple tests, and the two devices were tested under the same conditions, and the results obtained were basically the same. Said that such testing does not reflect actual usage. The 2%-3% difference Apple found by collecting customer data is manufacturing tolerance, and such differences will occur even between two devices using the same foundry chip.

Is the 6s CPU Samsung or TSMC? After seeing the "CPU Gate" incident above, everyone must be very curious about whether the 6s CPU in their hands is Samsung or TSMC. The following is a summary. The editor will teach you how to check the 6s CPU:
