本文只有一个目的,那就是全方位聊聊Apple Silicon M系列芯片这三年的发展,以M1 Pro、M2 Pro、M3 Pro为主线,看看这三年苹果都做了啥,以及M系列芯片的高度究竟如何。 本文2万字,阅读大概需要50分钟!如有帮助,…
而且这个能力并不局限于Mac,同样适用于使用M1/M2芯片的iPad。 考虑到ZRAM和SWAP可以额外提供不止10GB的“虚拟内存”,其实整体效果是可以高于16GB的。比如这个MacBook Air M1 8GB,都加载18GB内存数据了,内存压力也就才标黄,远没有到变红卡顿的程度。 某些很懂计算机的人,张嘴就来ZRAM和SWAP是古老技术,那么问题来...

Apple's latest M3 Pro chip in the new 14-inch and 16-inch MacBook Pro has 25% less memory bandwidth than the M1 Pro and M2 Pro chips used in...
With the M1, available memory maxed out at 16GB, but the M1 Max supports up to 64GB. It also offers up to 400GB/s memory bandwidth, 2x more than the M1 Pro and 6x more than the M1. Media Engine ...
Depends on what you're after, but the bump up to 24GB of RAM and doubling of the memory bandwidth is a huge jump forward. Show more What comes after the M2? The M2 is just the beginning. If things pan out like they did for the M1, we'll be seeing M2 Pro, Max, and Ultra chi...
While conducting performance evaluations, I've noticed that on M1/M1 Pro/M1 Max, the kernel demonstrates an impressive memory bandwidth utilization of around 90%. However, when executed on the M1 Ultra/M2 Ultra, this figure drops to approximately 65%. My suspicion is that this discrepancy is ...
One large feature of both chips is their much-increased memory bandwidth and interfaces – the M1 Pro features 256-bit LPDDR5 memory at 6400MT/s speeds, corresponding to 204GB/s bandwidth. This is significantly higher than the M1 at 68GB/s, and also generally higher than competitor laptop ...
The M1 Pro offers up to 400 GB/s of memory bandwidth as well as support for up to 64GB of unified memory. The efficient architecture of M1 Pro means they deliver the same level of performance whether MacBook Pro is plugged in or using the battery. With up to a 32-Core GPU, the M1...
