当人们谈论他们电脑的强大性能时,我们听过各种各样的说法:我的台式电脑比阿波罗登月计划用的电脑更强大;我口袋里的手机比整个阿波罗航天计划更强大;我的手表比登月舱更强大;以及最新的说法:我的钥匙扣比阿波罗飞船更强大。这些说法哪一个是真的? 在这一集中,我们将深入分析,并顺便回顾一些计算机历史。 链接: https://en.wikipedia.org/wiki/ENIAC https://en.wikipedia.org/wiki/Apollo_Guidance_Computer https://www.ibm.com/history/space-shuttle https://www.nordicsemi.com/Products/nRF52840 主持人: Jim McQuillan的联系方式是 [email protected] Wolf的联系方式是 [email protected] 在Mastodon上关注我们:@[email protected] 如果您有任何反馈,请发送至 [email protected] 访问我们的网页:http://RuntimeArguments.fm 主题音乐: Dawn by nuer self, from the album Digital Sky

## 钥匙扣 vs. 月球着陆器:计算能力比较 最近在Hacker News上的一场讨论源于一个播客问题:现代钥匙扣是否比阿波罗登月着陆器的导航计算机拥有更强的计算能力?答案是**肯定的**,而且差距很大。 尽管登月着陆器的计算机在当时是突破性的,拥有大约2MHz的处理速度、72KB的ROM和4KB的RAM,但如今的钥匙扣通常包含一个nRF52840l芯片,配备64MHz的ARM处理器、1024KB的Flash和256KB的RAM。这代表着能力上的巨大飞跃。 评论者指出,这种趋势延伸到许多日常设备——USB充电器、数码温度计,甚至一次性电子烟——都包含比必要更多的计算能力,仅仅是因为组件价格低廉。讨论还强调,虽然现代设备在处理能力方面表现出色,但登月着陆器的系统是针对特定任务进行优化的,并且面临电力和重量等限制。最终,这个比较生动地说明了技术进步的速度有多快。

When people talk about the power of their computers, we've heard all kinds of claims:

  • I have more power on my desktop computer than the Apollo had to put a man on the moon
  • The phone in my pocket has more power than the Apollo space program had
  • I have more power on my wrist watch than the lunar lander
  • And the latest one: I have more power in my key fob than the Apollo capsule had

Are any of these true?  In this episode, we break it down and enjoy a bit of computing history along the way.
