According to reports, Apple’s A15 Bionic offers no major CPU upgrades and only a little increase in transistor density

Admin

Apple announced the A15 Bionic chipset during the California Streaming event yesterday. This component will power the whole iPhone 13 series of phones, as well as the upcoming iPad mini. It’s made by TSMC, the world’s largest foundry, using its improved 5nm course of node (5NP). Compared to the A14 Bionic, the transistor count on the A15 Bionic increased by 27% to 15 billion transistors.

Typically, the higher the transistor density, the more efficient and effective a device is. Despite the jump in transistor count from 11.8 billion to fifteen billion, the A15 Bionic’s transistor density, which quantifies the number of transistors that fit into a square millimeter, increased by less than 1%. The A14 Bionic’s transistor density of 134.09 million transistors per square mm was reduced to only 135.14 million transistors per square mm on the new chip.

According to the report, Apple’s unveiling of a whole new chip with minor CPU advances is the result of a “mind drain” within the company

Because of this minor improvement in transistor density, a recent report from Semi Analysis claims that the new chip’s CPU hasn’t seen any significant improvements. Instead, it appears that Apple has deferred the release of its next-generation CPU core until the following year. There has been a lot of turnover at Apple, so we think the later era CPU core has to be delayed because of that. This year’s processor uses a modified version of last year’s core instead of a new one.

According to the article, Apple has seen a “brain drain” as the company has recently lost a number of key employees, including Gerard Williams III, who designed the company’s A-series semiconductors from the A7 through the A12X. Semianalysis claimed that Apple was obviously investing its transistor finances in the non-CPU aspects of the SoC.

The A15 Bionic contains 27% more transistors than the A14, but has a less than 1% increase in transistor density. While Apple claims a 40% boost in efficiency for the new sixth-generation iPad mini, which will be equipped with the A15 Bionic chip, this only applies to the A12 Bionic chip that was utilized in the fifth-generation iPad mini. The fresh new chip is also responsible for the new iPad mini’s 80 percent increase in GPU efficiency.

Apple usually announces how much of a performance boost to anticipate from the new processor it introduces each year in the iPhone. The comparisons made by the company with the iPad Mini are unimportant because it is comparing their newest 2021 chip with one that is three years old. Loads can alter in three years with the advancements that may be achieved in semiconductors on a regular basis.

Apple failed to meet its goals for increased efficiency with the iPhone 13 range, which uses the A15 Bionic SoC

When it came time for Apple to debut the iPhone 13 series and unwrap the A15 Bionic, it talked about the chip’s 15.8 trillion operations per second, which is 44 percent more than the A14 Bionic’s 11 trillion operations per second. Apple also mentioned the Professional versions’ 5 core GPU, which it claims would deliver the best graphics on any smartphone. However, Apple made no mention of the A15 Bionic’s efficiency and power consumption improvements over the A14 Bionic from last year.

The upgraded show engine is essential for the ProMotion 120Hz display, which updates the show 120 times every second, and the new ISP supports greater photograph and video algorithms. The system cache has been increased to 32MB, and the RAM chip has been upgraded from LPDDR4X to LPDDR5.

Why has Apple remained silent? According to SemiAnalysis, this was a premeditated act by Apple. Instead of saying that the A15 Bionic’s CPU was 50% faster than last year’s A14 Bionic, Apple announced that the new chip’s CPU was 50% faster than the competition, a collection of unnamed semiconductors from companies like MediaTek, Samsung, and Qualcomm. Furthermore, the slower chips used in Apple’s comparison will be swiftly replaced by faster chips from the “competitors.”
