Apple M1是苹果公司的系统芯片（SoC），可在2020年底的MacBook Air，MacBook Pro 13和Mac Mini中找到。它提供8个内核，分为4个性能内核和4个功率效率内核。大内核提供192 KB指令高速缓存，128 KB数据高速缓存和12 MB共享L2高速缓存。据苹果公司称，这些内核的性能应该比市场上的任何产品都要好（2020年末）。四个效率内核要小得多，并且仅提供128 KB指令高速缓存，64 KB数据高速缓存和4 MB共享高速缓存。
M1有两种TDP型号，一种是MacBook Air的被动冷却10瓦型号，另一种是MacBook Pro 13和Mac Mini的主动冷却更快型号。据苹果公司称，这些应该提供更好的性能。
M1中的集成显卡提供8核（入门级MacBook Air为7核），峰值性能为2.6 teraflops。苹果公司宣称，它在发布时比任何其他iGPU都要快。

The Apple M1 is a System on a Chip (SoC) from Apple that is found in the late 2020 MacBook Air, MacBook Pro 13, and Mac Mini. It offers 8 cores divided in four performance cores and four power-efficiency cores. The big cores offer 192 KB instruction cache, 128 KB data cache, and 12 MB shared L2 cache. According to Apple the performance of these cores should be better than anything on the market (in late 2020). The four efficiency cores are a lot smaller and offer only 128 KB instruction cache, 64 KB data cache, and 4 MB shared cache.
The M1 is available in two TDP variants, a passive cooled 10 Watt variant for the MacBook Air and an active cooled faster variant for the MacBook Pro 13 and Mac Mini. Those should offer a better-sustained performance according to Apple.
The integrated graphics card in the M1 offers 8 cores (7 cores in the entry MacBook Air) and a peak performance of 2.6 teraflops. Apple claims that it is faster than any other iGPU at the time of announcement.
