Google Pixel

I'm just going to put this information here: the use case for 46Gb WiFi is going to be extremely niche. There is nearly no legitimate use case where you can achieve that speed on your phone.

The problem here is that:

1. The majority of internet traffic is TCP
2. TCP protocol processing is atomic (i.e. your speed is bottlenecked by a single CPU)
3. The bottleneck is the receiver (i.e. downloader)
4. TCP is too complex for efficient receiver-side hardware offloads (i.e. can't workaround this issue by adding more special hardware)

What does this mean?

Your connection speed on a wifi 7 device WILL be bottlenecked by your single-core CPU speed, even if you are doing absolutely nothing except transmitting data. This assumes you are only using a TCP single connection (e.g. downloading a file from a website). But that's the majority of use cases unless you are running a server (in this case on your phone).

I haven't checked what CPU the Pixel 8 uses. But my Pixel 7 has a Cortex A-78. I also don't have the raw data handy for the 3Ghz A-78, but I do have data from the 2Ghz A-53 connected to a 100Gbps Ethernet NIC which is around 8-9Gbps. The A78 generally outperforms the A53 by 1.5x (At least that's the characteristics on the Nvidia Bluefield DPUs). So we can assume 12-14Gbps max for a single connection with Wifi 7 running on a state-of-the-art ARM CPU.

That is still nowhere near 46Gbps. It's like mounting a Vulcan Minigun on a bicycle.

To use the full wifi bandwidth, you would need to have multiple connections running on different cores. That's also not including the switches/servers connected to the wifi AP. Unless you are running a Redis server on your phone, I see no reason why Wifi 7 would be needed unless the remaining hardware is upgraded significantly.
