Today, NETGEAR has announced the Nighthawk X4 802.11ac router. It is dual-band, with up to 1733 Mbps of bandwidth (four channels of 433 Mbps) on 5.0 GHz and up to 600 Mbps (three channels of 200 Mbps) on 2.4 GHz. Compared to the Nighthawk X6, released earlier in the year, the X4 is design for fewer users who demand more performance.
The first thing that stood out for me was its processor...s. The router contains two of them. Its main CPU is a dual-core Qualcomm
Snapdragon-based (Update - Sept 2nd @ 5:20pm EDT: "Snapdragon-based" is unclear and misleading. It has "Snapdragon DNA with dual Krait cores". It is from their Qualcomm Internet Processors (IPQ) line, as mentioned in the following sentence.) ARM processor, clocked at 1.4 GHz. It is from their Qualcomm Internet Processors (IPQ) line, so it is not directly comparable to an SoC from their mobile line-up. NETGEAR also added a second, dualcore processor, clocked at 500 MHz, that is dedicated to deal with WiFi-related tasks as an "offload".
The reason why I found this interesting was that, not too many years ago, routers did not advertise their processor and RAM. There was once a niche who would create their own routers out of old PCs and an x86-compatible firmware (like OpenWRT). The push was to cheap routers with high bandwidth ratings. When I asked NETGEAR at what point did the industry decide to take the internal hardware seriously, their response was that about 73% of customers are repeat buyers. They upgraded their router because they were not happy with the performance that they were getting. Users have changed. HD video is going to numerous devices all over the home at the same time as games and downloads do their thing. The extra performance is necessary to keep the potential bandwidth in line with its usage.
One feature about this router that NETGEAR was promoting is Dynamic QoS. Using the extra processing power, mentioned in the two paragraphs above, the device identifies applications and allocates bandwidth accordingly. One example that they gave is YouTube versus Netflix. While both stream, Netflix will only grab what it needs while YouTube will load as quickly as possible to buffer ahead. If resources are tight, and Netflix is attempting to coexist with YouTube at any given time, the router will throttle the YouTube stream to provide it with at least enough bandwidth to stream, but not buffer, like, ten times faster than real time and choke out Netflix into a lower bit rate. If necessary, it will also prioritize the larger screen (TV) with the higher bit rate Netflix connection, where it will be more noticeable (than the smaller screen of a tablet, for instance).
And yes, QoS has been present in routers for more than a dog's age. They claim that it is typically a feature that users turn on, dislike, then turn right back off again. They believe that their new implementation will actually win you over.
The router will also feature two USB 3.0 ports and an eSATA connection. It will allow networked PC backup to an external hard drive and streaming media (photos, music, and videos) to TVs by DLNA.
The NETGEAR Nighthawk X4 AC2350 (R7500) is available now for $279.99.
