GoFetch is a family of cryptographic attacks on recent Apple silicon CPUs that exploits the CPU's on-chip data memory-dependent prefetcher (DMP) to investigate the contents of memory. [ 2 ] [ 1 ] CPUs affected include the M1 , M2 , M3 and A14 series system-on-a-chip processors.
The original M1 chip was introduced in November 2020, and was followed by the professional-focused M1 Pro and M1 Max chips in October 2021. The M1 Max is a higher-powered version of the M1 Pro, with more GPU cores and memory bandwidth, a larger die size, and a large used interconnect. Apple introduced the M1 Ultra in 2022, a desktop workstation ...
Apple's latest M1 Ultra processor is a boon for consumers and a threat to the chip industry. Apple’s M1 Ultra chip is good for you, but a problem for Intel, AMD, and Nvidia [Video] Skip to main ...
Pacman [a] is a side-channel vulnerability in certain ARM CPUs that was made public by Massachusetts Institute of Technology security researchers on June 10, 2021. It affects the pointer authentication (PAC) mechanism in many ARMv8.3 chips, including Apple's M1 CPU. [1]
The M1 Pro and M1 Max have a 16-core and 32-core GPU, and a 256-bit and 512-bit LPDDR5 memory bus supporting 200 and 400 GB/s bandwidth respectively. [20] Both chips were first introduced in the MacBook Pro in October 2021. [21] The M1 Ultra is a processor combining two M1 Max chips in one package. [22]
Apple used a super-wide processor design paired with fast memory and cache to create a speedy, efficient processor for its new Macbook Pro. Apple's M1 isn't witchcraft, it's good chip design ...
The M1, Apple's first system on a chip designed for use in Macs, is manufactured using TSMC's 5 nm process. Announced on November 10, 2020, it was first used in the MacBook Air, Mac mini and 13-inch MacBook Pro, and later used in the iMac, 5th-generation iPad Pro and 5th-generation iPad Air. It comes with 4 performance cores and 4 efficiency ...
In March 2022, Apple announced the Mac Studio, a new high-end compact desktop model that uses the M1 Ultra, a dual-SoC configuration of two M1 Max chips. [ 48 ] [ 49 ] Apple concurrently discontinued the 27-inch Intel-based iMac , leaving the Mac Pro and Core i5/i7 Mac Mini as the last Intel-based Macs. [ 50 ]
