The 2020 iPad Pros

新的2020 iPad专业人员在最多的方式是2018年iPad专业人员的次要规范颠簸更新。相机系统更好,有一个新的LIDAR传感器,大大改善了AR,内置麦克风系统明显改善。那是关于它的。

That’s not a complaint. The 2018 iPad Pros were amazing devices, way ahead of their time in terms of performance. If it’s going to take two or more years between truly major updates to the iPad Pro, I want Apple to release a spec bump update mid-cycle. That’s what these iPad Pros are.

性能

让我们首先脱离这一点。我正在使用这句话“规格凹凸“而不是”speed撞”来描述这些新iPad赞成因为他们don’t really seem to be much faster than the 2018 models. Some numbers fromGeekbench 5

Single Compute
2018年12.9“iPad Pro 1,124 4,675 9,183
2018 11“iPad Pro 1,118 4,543 9,059
2020 12.9“iPad Pro 1,123 4,691 10,046
2020核心I5 MacBook Air 1,127 2,854 4,950
2019 Core i9 16″ MacBook Pro 1,263 7,277 25,351.
2019 iPhone 11 Pro 1,338 3,467 6,310

The thing worth noting is that the new iPad Pros sport a system-on-a-chip that Apple is calling the A12Z. The 2018 models use the A12X. Both are 8-core designs, with 4 high-performance cores and 4 high-efficiency cores. The way that works, basically, is that when your iPad is not breaking a sweat computationally, it uses the 4 high-efficiency cores; when it is breaking a sweat, it switches to the high-performance cores. The 8-core MacBook Pro scores better on the multi-core benchmark because its 8 cores are all, effectively, high-performance cores.

值得注意的是A13供电的iPhone 11的数字。A13在单核性能方面比核心I9 16英寸MacBook Pro更快,但A12X和Z保持自己,并且仍然在多个-核心。

Real-world performance may differ more significantly, but from what I can tell, A12Z CPU performance is unchanged from the A12X and GPU performance is only slightly improved. But iPad Pro performance was already great. Look at those numbers — the iPad Pro outperforms the new mid-range MacBook Air. The 16-inch MacBook Pro I’ve compared it to here starts at $2,800 and it weighs 4.3 pounds (2.0 kg).

另一种规格调整:2018年iPad Pro型号带有4 GB的RAM,除了带有1 TB的存储器 - 那些带有6 GB的RAM。Apple从不与iOS设备讨论RAM,但它很容易识别使用第三方实用程序的设备中的多少RAM。使用2020阵容,所有型号似乎都有6 GB的RAM。实际上,这意味着新的iPad专业人员应该能够在不从头开始重新加载它们的同时保持更多应用程序。在我的个人日常使用中,我没有注意到差异。

LIDAR和双镜头相机

作为承诺,激光雷达大大提高了AR雄厚ce. No more warmup period where AR apps want you to pan the device around to allow the system to orient itself and get a sense of your environment — you just launch the app and it’s ready. I mostly tested this with Apple’s Measure app. Measuring the sizes of furniture and countertops is much faster, easier, and more accurate. I just measured a 3-foot shelf here in my office and the Measure app pegged it at precisely 36 inches, on the button.

LIDAR传感器也有助于识别墙壁和天花板。这同样容易衡量措施来判断有多远的东西 - 再次说,一块家具 - 来自墙壁,因为它是测量自己本身的大部分。在所有其他IOS设备上 - 这就是说,所有非LIDAR设备的IOS设备 - 措施都不擅长。

In short, if you’re an AR junkie, you should jump all over the new iPad Pro. If you’re not an AR junkie — which is to say the overwhelming majority of you — well, it’s not that big a deal. I don’t mean to be dismissive of AR and ARKit. I think an AR revolution is coming, and the whole “use your iPhone and iPad as ARKit devices” effort on Apple’s part — and it’s a massive effort — is laying the groundwork for an AR-first device to hit the ground running with developer support from day one. But are there really people for whom ARKit-powered apps are so important right now that they’ll upgrade to a new iPad just for lidar support? I suppose the answer is yes — for example, developers working on ARKit apps and games. But for most people the answer is clearly no.

新的iPad专业专业人员的新型宽/超宽双镜头摄像头系统在纸张上看起来很像非Pro iPhone 11上的宽/超宽双镜头系统。以及常规静止摄影的结果并且视频看起来非常可比。但是至少有一个显着差异:iPad Pro不支持带有主摄像头的纵向模式;iPhone 11确实如此。(iPad Pro支持纵向模式与前面的自画像相机。)我怀疑的一个原因是iPhone 11具有A13芯片,而iPad优点具有上一代A12Z。The iPad Pro wide/ultra-wide cameras may in fact be the exact same cameras as the iPhone 11 — I don’t know, and Apple doesn’t make statements like that — but the iPad Pro can’t use the same software path for Portrait mode that the iPhone 11 does because Portrait mode makes heavy use of machine learning and that means the Neural Engine — but the A13 Neural Engine is far more powerful than that of the A12Z. This could be the sort of thing that just didn’t make it for a mid-cycle iPadOS 13.4 software release; it wouldn’t surprise me if the new iPad Pros gain Portrait mode in iPadOS 14.0.

In the meantime, I think supporting Portrait mode on the new iPad Pro would have required engineering effort that Apple instead chose to expend on supporting the lidar sensor for AR.

理论上,激光雷达传感器可用于帮助静止摄影和视频。人们可以想象如何帮助纵向模式 - 使用LIDAR进行深度图,基于它们的距离,以将对象和风景模糊到背景中。利达还可以帮助识别眼镜,帽子,头发等。这并不是那么简单。新型iPad Pro中的LIDAR传感器在Z轴(深度)上具有巨大的精度,但在x和y轴上没有太大。它只是没有项目many dots. But the iPad Pro makes up for the lack of X/Y accuracy when you pan the iPad Pro around, by continuously scanning the dots in real time as you pan. When shooting still photos or video, however, you can’t assume that the user is going to pan. The iPad might even be locked down on a tripod. I do expect Apple to eventually use lidar, or something like lidar, as a focusing and depth-map aid for photography, but they’re not there yet. This lidar system is clearly designed for 3D mesh generation, not 2D depth mapping.

新麦克风阵列

One other notable hardware change in the 2020 iPad Pro: Apple claims it now uses the same five-microphone “studio quality” array that they introduced withthe 16-inch MacBook Pro in November。Indeed, it does sound better, and background noise is reduced. Here are recordings I made side-by-side with a 2018 iPad Pro and the new 2020 iPad Pro. I can easily hear the improvement — richer sound, higher quality, and less noise.

2020 iPad Pro:

This Is All Just a Prelude to the Thing We Really Want to Review

I’ve been testing a 12.9-inch iPad Pro with 1 TB of storage since Thursday (five days ago). Apple included the updated Smart Keyboard cover. There are two differences from the Smart Keyboard cover for the 2018 iPad Pros — (1) the camera cutout has been embiggened to accommodate the larger camera/lidar system; and (2) the back of the covernow has an debossed Apple logo,面向景观,宣传。

苹果做了notinclude the product I really want to test, and which all of you really want to read about: the new魔术键盘封面。It’s no surprise that Apple has not yet made them available for review: they’re not shipping until “May”, and with the exception of the original AirPods, I can’t recall Apple providing reviewers with hardware more than a week or so in advance of shipping.

事实是我只是不喜欢智能键盘封面。我不喜欢键入它,我想要一个触控板。

What I do when I write on my iPad is use a Bluetooth or USB keyboard. Apple’s蓝牙魔术键盘is a great option — I particularly like it in工作室整洁的顶篷覆盖/立场。I also enjoy writing on my iPad using a standalone external mechanical keyboard. One reason I prefer a standalone keyboard over the Smart Keyboard cover is simply that the keyboards feel better. But another is that if you’re setting it up on a desk or countertop, there’s no need to magnetically snap the iPad into a case, cover, or stand. You can just prop it up, which makes it utterly seamless to pick it up with one hand and walk away from the keyboard setup when you just want to go somewhere else with the iPad. It also allows you to do something with the iPad that no dedicated laptop can do: orient the screen vertically rather than horizontally, which makes a lot of sense for long-form writing. Here, for example,是我的设置,因为我写这个非常审查1

That said, I am deeply intrigued by the iPad Pro Magic Keyboard. In the meantime, we wait.

The Bottom Line

如果您已经拥有2018年iPad Pro,甚至考虑升级的唯一原因是您是否以某种方式与AR专业涉及,或者您是否严格使用iPad摄像头。这些不是newiPad Pros so much astweakediPad专业人士。并且持有2018年iPad Pro的最佳部分是即将到来的魔术键盘与这些模型完全兼容。保留2018年iPad Pro并等待键盘。

If you don’t have a 2018 iPad Pro, I can recommend these new iPad Pros with no reservations.Everything I wrote about the 2018 iPad Pros still stands。谣言比比皆是,苹果可能会在年底发布更重要的iPad Pro更新,也许只有12.9英寸尺寸。如果你想等待,等待,但等待传闻未来的产品是将自己绑在结和整天等待的好方法。如果您现在需要一个新的iPad,这些是苹果公司最好的iPads,并且可以说是苹果的最佳便携式计算机已经完成了。
