Apple MacBook Pro 14 2021 M1 Pro Laptop in Review: How much "Pro" do you get with the base model?
Apple M1 Pro 8-Core | Apple M1 Pro 14-Core GPU | 14.20" | 1.6 kg
The Apple M1 Pro 8-Core is a System on a Chip (SoC) from Apple that is found in the late 2021 MacBook Pro 14 and 16-inch models. It offers 8 cores from the 10 available in the chip divided in six performance cores (P-cores with 600 - 3220 MHz) and four power-efficiency cores (E-cores with 600 - 2064 MHz). The cores are similar to the cores in the Apple M1.
The big cores (codename Firestorm) offer 192 KB instruction cache, 128 KB data cache, and 24 MB shared L2 cache (up from 12 MB in the M1). The four efficiency cores (codename Icestorm) are a lot smaller and offer only 128 KB instruction cache, 64 KB data cache, and 4 MB shared cache. Finally, the SoC includes 16 MB System Level Cache shared by the GPU. The efficiency cores (E cluster) clock with 600 - 2064 MHz, the performance cores (P cluster) with 600 - 3228 MHz.
The unified memory (16 or 32 GB LPDDR5-6400) next to the chip is connected by a 256 bit memory controller and can be used by the GPU and CPU.
The integrated graphics card in the M1 Pro offers 14 cores (of the 16 cores in the chip).
Furthermore, the SoC integrates a fast 16 core neural engine, a secure enclave (e.g., for encryption), a unified memory architecture, Thunderbolt 4 controller, an ISP, and media de- and encoders (including ProRes).
The M1 Pro is manufactured in 5 nm at TSMC and integrates 33.7 billion transistors. The peak power consumption of the chip was advertised around 30W for CPU intensive tasks.
