Tesla’s new onboard computer is twice as fast as the older version, shows test
Tesla recently confirmed having updated the onboard media computer (MCU) in
the new Model S and Model X, which is resulting in an evidently faster and
smoother experience.
Tesla证实现在新出厂的Model S/X 都已经换上新的MCU，明显有更快更流畅的体验
Now owners have tested the response time of the new MCU and it seems to be as
much as twice as fast as the older version.
有车主已经测试了新MCU的反应时间，并且似乎是比旧版本快两倍。
As we previously reported, Tesla developed a new dual computing platform for
Autopilot and the Media Control Unit MCU on the Model 3.
Tesla 在Model 3 上用上了新的MCU
For Model 3 owners who also owned Model S or Model X vehicles at some point,
it was clear that it resulted in a much faster and smoother touchscreen
experience on the center display than it Tesla’s two older vehicles.
对于同时拥有 Model S 或 X 与Model 3的车主来说，
很明显的在Model 3 上的中控萤幕触控起来更快更顺畅
Now Tesla is bringing the same experience to new Model S and Model X vehicles.
现在Tesla 正在为Model S/X 带来相同的体验。
A Model S owner with the new MCU did a series of controlled comparison tests
with the navigation system, vector map responsiveness, dash buttons
responsiveness, and web browser performance.
新MCU 的Model S 车主进行了一系列可控比较测试，导航系统、向量地图反应、
按钮反应能力和网络浏览器性能。
As you can see, aside from the dash buttons responsiveness, the new MCU
appears to be about twice as fast as the older version.
如你所见的，除了按钮的反应能力之外，在其他项目新的MCU 速度似乎是旧版本的两倍。
Tesla’s MCU has long been powered by Nvidia GPUs just like its Autopilot
computer, but the company moved to Intel for the Model 3, which first showed
sign of more performance and responsiveness.
Tesla 的MCU 一直以来都使用Nvidia GPU，但Model 3 则转用 Intel。
While it’s unconfirmed at this point, Tesla could have also moved to Intel
for the Model S/X MCU processor to get that kind of performance and use the
same processor and board for the MCUs in all its vehicle programs.
就在几分钟之前，Elon Musk 在推特上表示，旧的MCU硬件是可以升级的
并且也编写了软件用来加强旧MCU的表现(Big diff.)
只是到现在为止还没有说明这种硬件升级需要花车主多少钱(底下不少人在问价格)
本来Model 3 的触控萤幕体验要好过S/X 可能会让S/X 的车主有点小失落
现在把S/X 的MCU 更新了也多少能够消除现在想要购买S/X 的人心中的一点疑虑
而旧的S/X 也能够更新硬件，虽然可能是需要付费，但这种做法也还蛮少见的
就算车主没有打算花钱更新硬件，免费的软件支援也说会有很大的不同
