Intro
The video introduces Apple's "Scary Fast" event, which unveiled the new M3 chip lineup. While some aspects felt familiar, Apple made significant advancements and comparisons against the rest of the computer industry. The presenter notes that while PC laptops offer variety, Apple focuses on power efficiency, performance, and portability, consistently delivering on these key aspects. The new M3 chip is built on a three-nanometer process, and the announcement video was 30 minutes and 31 seconds long, held on October 30th, 2023.
The GPU
Apple is promoting the new three-nanometer GPU as the biggest leap forward in graphics architecture for Apple Silicon. Key additions include hardware-accelerated ray tracing and mesh shaders, technologies that are already familiar to PC gamers. These features are expected to significantly enhance the visual quality of games on Macs, with examples like Alan Wake 2 showcasing the benefits of mesh shaders. Apple's implementation of these technologies arrives at a time when they are becoming increasingly useful.
Dynamic Caching
The M3 chips feature dynamic caching, which optimizes the use of unified memory shared between the CPU and GPU. Instead of reserving a fixed portion of memory for the GPU, the M3 dynamically allocates the exact amount of memory needed at any given moment. This feature is available on all three new chips and is expected to dramatically increase the average utilization of the GPU. If implemented effectively, dynamic caching could be a major advantage of Apple's tightly integrated system.
The CPUs
The CPUs in the new M3 chips show impressive performance gains. The P cores and E cores are 30% and 50% faster than the M1, respectively, with improved branch prediction and increased core counts. The regular M3, found in the entry-level 14-inch MacBook, features an eight-core CPU, a 10-core GPU, and support for up to 24GB of unified memory. The M3 Pro has 12 CPU cores, 18 GPU cores, and up to 36GB of unified memory, while the M3 Max offers up to 16 CPU cores, up to 40 GPU cores, and up to 128GB of unified memory.
The Macbook Display & Battery life
Apple continues to excel in laptop displays with their Liquid Retina XDR display, which peaks at 1600 nits in HDR and 600 nits in SDR, with a 120Hz refresh rate. The M3 MacBooks offer significantly improved battery life compared to Intel-based Macs, providing up to 11 additional hours and up to 11x performance uplift. This performance remains consistent whether the device is plugged in or running on battery.
The iMac
The new iMac features a four and a half K display and is equipped with the regular M3 chip. The presenter questions the absence of Pro and Max models for the iMac. The presenter speculates that Apple may release additional iMac models with Pro and Max chips in the future to maintain their efficiency advantage, especially with competition from the Snapdragon X Elite and the progress of Windows on ARM.
Pricing
The 14-inch M3 MacBook is $400 less than the previous 14-inch model but $300 more expensive than the old entry-level model, with the base configuration including 8GB of unified memory and a 512GB SSD. Upgrading to 16-inch versions with M3 Pro and M3 Max chips can push the price to $3,000, $4,000, or even $7,000. The new iMac starts at $1,300 with a 256GB SSD, and upgrading to a terabyte of storage increases the price to $1,700, while still using the base M3 chip.
Outro
The video concludes by encouraging viewers to check out the channel's iPhone 15 coverage from earlier in the year, highlighting the A15 Pro chip.
