Unbuffered memory modules (UDIMMs) directly expose the memory chip interface to the module connector. Registered or load-reduced variants (RDIMMs/LRDIMMs) use additional active circuitry on the memory module in order to buffer the signals between the memory controller and the DRAM chips. This reduces the capacitive load on the DDR5 bus.
Products using LPDDR3 include the 2013 MacBook Air, iPhone 5S, iPhone 6, Nexus 10, Samsung Galaxy S4 (GT-I9500) and Microsoft Surface Pro 3 and 4. [10] LPDDR3 went mainstream in 2013, running at 800 MHz DDR (1600 MT/s), offering bandwidth comparable to PC3-12800 notebook memory in 2011 (12.8 GB/s of bandwidth). [ 11 ]
(The module provides pins for 11 lines, but many motherboards and modules provided only 8.) Some variants (illustrated to the right) placed the tag RAM on the motherboard and only the main cache RAM was on the module. Consider the 256K module first. An 8-bit tag allows caching memory up to 256 times the cache size, or 64 MiB.
It has 8 CPU cores (4 performance and 4 efficiency), up to 8 GPU cores, and a 16-core Neural Engine, as well as LPDDR4X memory with a bandwidth of 68 GB/s. The M1 Pro and M1 Max SoCs are fabricated by TSMC on the 5 nm process and contain 33.7 and 57 billion transistors respectively.
Reviewers lamented the base memory configuration of 8 GB on the standard M3 MacBook Pro. [152] In March 2024, the MacBook Air was also updated to include the M3 chip. [ 153 ] In October 2024, several Macs were announced with the M4 series of chips, including the iMac, a redesigned Mac Mini, and the MacBook Pro; all of which included 16 GB of ...
Steve Jobs introduced the MacBook Air during Apple’s keynote address at the 2008 Macworld conference on January 15, 2008. [4] The first MacBook Air was a 13.3-inch model, initially promoted as the world's thinnest notebook at 1.9 cm (0.75 in) (a previous record holder, 2005's Toshiba Portege R200, was 1.98 cm (0.78 in) high).
