Apple A18 vs Apple A6x vs Apple A6
Apple A18
► remove from comparison
The Apple A18 is a powerful smartphone processor and formal successor to the A16. This new member of the Apple A processor series debuted in September 2024 alongside the iPhone 16 and iPhone 16 Plus; it features 2 performance cores and 4 efficient cores along with a 35 TOPS NPU and the 5-core A18 GPU.
The chip is normally paired with 8 GB of RAM. It is said to be in large part based on the v9.2A ARM microarchitecture for near-Apple M4 IPC. 5G, Wi-Fi 7, Bluetooth 5.3, various satellite navigation systems and NFC are all supported here.
The more expensive A18 Pro SoC has the same 2 P-cores and 4 E-cores running at slightly higher clock speeds; its graphics adapter is on the other hand significantly faster than what the A18 has. Another crucial little detail is that USB 3.x support is either missing, or disabled somehow on the A18 for USB 2.0 speeds only whereas the A18 Pro has no such issue.
Performance
Multi-threaded benchmarks put it in the same ballpark as the Snapdragon 8 Gen 3 and the Dimensity 9300. As expected from Apple, the A-series processor delivers breathtaking single-thread performance that just about matches the significantly more power-hungry Apple M3 chip. This suggests the P-cores can almost hit the 4 GHz mark when required.
Graphics
Like any modern graphics adapter, the 5-core A18 GPU is RT-enabled. It delivers benchmark scores that are most comparable to the G715 MP11 and the G615 MP6.
Power consumption
It appears the chip is able to briefly consume up to about 9 W when under high load, with average sustained power consumption figures hovering around 3-4 W.
The pretty modern TSMC N3E manufacturing process makes the A-series chip very power-efficient, as of late 2024.
Apple A6x
► remove from comparisonThe Apple A6x is a dual-core-SoC (System on a Chip) with ARM compatible CPU cores (ARMv7s instruction set). Both can be clocked at up to 1400 MHz depending on the load. It is used in the iPad 4 and compared to the A6 in the iPhone 5, the A6x offers a faster GPU (PowerVR SGX544MP4).
The CPU-Performance of the A6x is similar to the Qualcomm Snapdragon S4 Pro MSM8960T, while the GPU is about as fast as the Adreno 320.
Apple A6
► remove from comparisonThe Apple A6 is a dual-core SoC found in the iPhone 5 with ARM compatible CPU cores. The A6 was developed by Apple and supports the extended ARMv7s instruction set. The clock rate of the CPU is between 800 to 1200 MHz depending on the CPU load. The integrated GPU is a PowerVR SGX543MP3 at 266 MHz.
