As we head into the holiday season, many of us are looking to find a new PC that will carry us through 2020–2021, or even longer. When making a decision about your primary computing device that will last several years, or making recommendations for friends and family, it’s critical that you address as many future needs as possible.

当我们进入假期季节时，我们中的许多人都在寻找一种新的PC，它将带我们到2020-2021年甚至更长。 在决定将要使用数年的主要计算设备或为亲朋好友提出建议时，至关重要的是要满足尽可能多的未来需求。

Most consumers tend to think about things like compute capability, graphics performance, memory capacity, battery life, and screen size, all of which are important. But what we often don’t think enough about is how this device will be connecting to the rest of the world: through Wi-Fi.

大多数消费者倾向于考虑诸如计算能力，图形性能，内存容量，电池寿命和屏幕尺寸之类的东西，所有这些都很重要。 但是，我们经常对此没有足够的思考：该设备如何通过Wi-Fi连接到世界其他地区。

Of particular interest to me was the recent Microsoft Surface launch, that featured competing solutions powered by Intel Core processors, AMD Ryzen, and even Qualcomm CPUs. What got seemingly little attention in reviews was the importance of Wi-Fi 6. Testing and evaluating wireless connectivity is a complicated task and can require specialized hardware or software to accomplish in a lab setting.

我特别感兴趣的是最近发布的Microsoft Surface，该产品采用了由Intel Core处理器，AMD Ryzen甚至Qualcomm CPU支持的竞争解决方案。 审查中似乎很少引起注意的是Wi-Fi 6的重要性。测试和评估无线连接是一项复杂的任务，可能需要专门的硬件或软件才能在实验室环境中完成。

At Intel, I asked our labs to evaluate the real-world Wi-Fi performance of the different Surface devices released this fall as I was genuinely curious what results we would see. Here are a couple of comparisons of recently announced Surface devices, looking at maximum throughput capability.

在英特尔，我请实验室评估今年秋天发布的各种Surface设备的真实Wi-Fi性能，因为我真的很好奇我们会看到什么结果。 以下是一些最近发布的Surface设备的比较，它们着眼于最大吞吐能力。

Surface Laptop 3 with AMD Ryzen vs Surface Laptop 3 with Intel Core

Comparing the Surface Laptop 3 with the Intel Core i5 platform (both Core i5 and Core i7 13” and 15” models have Wi-Fi 6) against a model with AMD Ryzen, Intel Wi-Fi 6 Gig+ with 160 MHz channels offers more than 2x faster usable download and upload speeds and more than 2.6x peak theoretical throughput.

将Surface Laptop 3与Intel Core i5平台(Core i5和Core i7 13”和15”型号均具有Wi-Fi 6)与带有AMD Ryzen的型号进行比较，具有160 MHz通道的Intel Wi-Fi 6 Gig +提供了更多的功能。可用下载和上传速度提高了2倍，理论吞吐量达到了2.6倍的峰值。

Surface Pro X with Qualcomm SQ1 vs Surface Pro 7 with Intel Core

具有Qualcomm SQ1的Surface Pro X与具有Intel Core的Surface Pro 7

*有关配置详细信息，请参见下文

The Surface Pro 7 with Intel 10th Generation Core and Wi-Fi 6 integration leads the Qualcomm-powered Surface Pro X with ~3x faster download and upload speeds and nearly 3.5x the maximum theoretical Wi-Fi connectivity speeds.

具有英特尔第10代核心和Wi-Fi 6集成的Surface Pro 7以高出约3倍的下载和上传速度和接近3.5倍的最大理论Wi-Fi连接速度，领先于高通供电的Surface ProX。

This download and upload testing was completed with 30GB file transfers using the WinSCP application from a host PC with a 10GigE network connection to a Wi-Fi 6 enabled router. For maximum peak throughput we used the iPerf networking tool and measured average throughput over a 300 second period.

使用WinSCP应用程序从具有10GigE网络连接的主机PC到启用Wi-Fi 6的路由器的30GB文件传输完成了此下载和上传测试。 为了获得最大的峰值吞吐量，我们使用了iPerf网络工具，并测量了300秒内的平均吞吐量。

These are not insignificant differences in wireless performance, and as you think about a laptop that you will be using for the next 1–3 years, getting one with Wi-Fi 6 should be at the top of your list.

这些在无线性能上并不是微不足道的差异，并且考虑到您将在未来1-3年内使用的笔记本电脑，将Wi-Fi 6与笔记本电脑搭配使用应该列在列表的顶部。

The technology of Wi-Fi 6 is radically different than previous generations and is the biggest shift to Wi-Fi in more than a decade. Wi-Fi 6 changes network traffic from a contention-based, random, best effort to a more robust router-managed solution that provides increases in reliability and efficiency. Updating your home to a router with Wi-Fi 6 Gig+ capability is necessary to maximize these benefits.

Wi-Fi 6的技术与前几代产品完全不同，并且是十多年来向Wi-Fi的最大转变。 Wi-Fi 6将网络流量从基于争用的随机最佳努力转变为功能更强大的路由器管理的解决方案，从而提高了可靠性和效率。 要使这些优势最大化，必须将您的房屋更新为具有Wi-Fi 6 Gig +功能的路由器。

Even at base specifications, Wi-Fi 6 provides nearly 40% faster speeds, up to 75% lower latency, and support for up to 4X more devices vs. Wi-Fi 5.

即使是基本规格，Wi-Fi 6的速度也快近40％，延迟降低了75％，与Wi-Fi 5相比，支持的设备最多增加了4倍。

On top of that, Intel’s Wi-Fi 6 Gig+ solutions for PCs and routers support 160 MHz channels, enabling Gigabit Wi-Fi speeds nearly 3x faster vs. standard Wi-Fi 5, which is what you see above.

最重要的是，英特尔面向PC和路由器的Wi-Fi 6 Gig +解决方案支持160 MHz通道，与标准Wi-Fi 5相比，千兆位Wi-Fi的速度快了将近3倍，这就是您在上面看到的。

And as we move into the world of 5G connectivity, the need for Wi-Fi 6 will increase as it can provide reliable, high-speed, low-latency, and greater capacity capabilities that are required to deliver services in the 5G ecosystem.

随着我们进入5G连接世界，对Wi-Fi 6的需求将会增加，因为它可以提供在5G生态系统中交付服务所需的可靠，高速，低延迟和更大容量的功能。

Wi-Fi 6: Biggest PC Connectivity Update, footnote 4. 2.75% Latency reduction: is based on Intel simulation data (79%) of 802.11ax with and without OFDMA using 9 clients. Average latency without OFDM is 36ms, with OFDMA average latency is reduced to 7.6ms. Latency improvement requires that the 802.11ax (Wi-Fi 6) router and all clients support OFDMA.

Wi-Fi 6：最大的PC连接更新，脚注 4。2.75 ％的延迟减少 ：基于使用和不使用9个客户端的OFDMA的802.11ax的Intel仿真数据(79％)。 不使用OFDM的平均等待时间为36ms，使用OFDMA的平均等待时间减少到7.6ms。 延迟的改进要求802.11ax(Wi-Fi 6)路由器和所有客户端都支持OFDMA。

Wi-Fi 6: Biggest PC Connectivity Update, footnote 5. About 40% faster: ~40% claim based on maximum theoretical data rates for dual spatial stream Wi-Fi 6 of 1201Mbps verses dual spatial stream 802.11ac (80MHz) of 867Mbps which yields a 39% improvement. Intel internal Wi-Fi 6 testing shows an even greater improvement when testing at 3M distance with Wi-Fi 6 (80MHz) average throughput of 907Mbps verses 802.11ac (80MHz) average throughput of 541 for an improvement of 68%. Wi-Fi 6 improvements requires use of similarly configured Wi-Fi 6 network routers.
