IT Home October 5 Apple unveiled the iPhone 13 Series phone at its September launch, featuring the latest A15 bionic processor. Apple claims that the A15 is 50% faster than its competitors.
According to MacRumors, AnandTech has conducted several independent tests of chip performance, efficiency, and graphics cores, and the results show that the A15 is not 50 percent faster than Apple claims to be, but 62 percent faster.
The report shows that the A15 has two new CPU microarchitectures, including two performance cores and four efficiency cores, which may have been manufactured using processes of more than 5 nanometers, which TSMC calls N5P, a "performance enhancement" of its 5nm process that allows for higher frequencies.
In addition, AnandTech notes that the A15 system cache has been upgraded to 32MB, double the A14 cache.
The report notes that this doubling "dwarfs competitors" and is a key factor in the chip's power efficiency, allowing memory access to remain on the same silicon rather than to slower, more power-hungry DRAM.
However, Apple's overall cooling design is considered "absolutely the worst" because it doesn't spread heat well across the phone's body, IT House learned. However, even with limited cooling capacity, the iPhone 13 model is still much faster than competing phones and offers a better gaming experience.
Overall, AnandTech's test report noted that the A15 improvements were "substantial" and said efficiency improvements were "critical" to the iPhone 13 Series' significantly longer battery life.
