M6 MacBook Pro's 170GB/s Memory Bandwidth Skips Base 16GB Model
The just-announced 14-inch MacBook Pro with M6 chip features memory bandwidth of up to 170GB/s, up from 153GB/s in the M5 model, but notably the performance increase doesn't stretch to the base 16GB configuration. According to Apple's tech specs page , the option for 16GB of unified memory remains limited to 153GB/s. That's identical to the M5 version, while only the new 24GB and 32GB configurations receive the faster 170GB/s memory bandwidth. For comparison, the high-end MacBook Pro with M5 Pro chip offers 307GB/s memory bandwidth, and the high-end model with the M5 Max features up to 614GB/s memory bandwidth. Pricing starts at $1,999, with 16GB of unified memory and 1TB of storage as standard. The new 14-inch MacBook Pro is available in Space Black and Silver, with configurations up to 32GB of memory and 4TB of storage. The new MacBook Pro is available to pre-order from Wednesday ahead of a November 6 launch.
