Apple M4 moves to TSMC N3E
Apple has developed a 10 core CPU with up to 28bn transistors for its latest iPad designs.
www.eenewseurope.com/, May. 07, 2024 –
The Apple M4 has a new up-to-10-core CPU design with 28bn transistors consisting of up to four performance cores and now six efficiency cores. This is built on TSMC's N3E second generation of 3nm process technology for energy efficiency.
The cores use the ARM instruction set architecture (ISA) but have have improved branch prediction, with wider decode and execution engines for the performance cores, and a deeper execution engine for the efficiency cores. Both types of cores also feature enhanced, next-generation ML accelerators.
This provides 1.5x faster CPU performance over the 20bn transistor M2 built on TSMC's 5nm N5P process with the same performance at half the power consumption.
- Dynamic caching boosts raytracing in Apple's 3nm M3
- Apple completes its ARM lineup with 5nm, 134billion transistor M2 Ultra
The 10 GPU cores from the previous M3 support hardware-accelerated ray tracing for more realistic shadows and reflections in games and other graphically rich experiences.
Dynamic Caching allocates local memory dynamically in hardware and in real time to dramatically increase the average utilization of the GPU, while hardware-accelerated mesh shading provides more efficiency in geometry processing, enabling more visually complex scenes in games and graphics-intensive apps.
