> Garmin watches that have mapping support have an introduction price of >600 Euro. Even at that price point, zooming or panning maps is excruciatingly slow
I just got a Garmin Instinct 3 Solar. It does mapping, and cost me about $300 US.
You're right that it's slow due to a wimpy processor. But the processor isn't because they're too lazy to innovate, but because they have something sipping tiny amounts of power so that I can get a battery life of several weeks.

As a sibling commenter said, the Instinct 3 Solar only does breadcrumb navigation, it doesn't do topographic maps on the watch (there are some Connect IQ apps that can add mapping, but you don't get good integration with workouts).
I use them all the time when cycling. I often plan a route, but when some different direction looks more interesting, I can spot check whether it leads to bike paths that will eventually merge back into my grand plan, erm, route. Or sometimes even for following the route, you want to look ahead by quickly zooming out or get a lot of detail at some complex intersection, where having a full map gives you much better orientation.
Well, except on a Garmin, my Fenix 8 is often so slow that I had to pause cycling to zoom in/out (even more complicated by not being able to do gradual zooming because it does not have a crown).
Yes, I know I can also use a bike GPS or a more generic GPSr with a large screen. I have used their gpsmap line since 2010 or so and even have the gpsmap H1. But having to always carry it around when you have a break somewhere is a drag and I always have a watch on me anyway. So I primarily use the gpsmap for geocaching and switched to using a watch for other activities.

Coros watches have several weeks of battery life and fast maps. It is laziness (or margin maximization), because they could reach the same power budget by moving to a processor that is on a smaller node.

Their bike computers have a long lasting battery and are helpful for data. But wow are they frustrating. Software update regularly loses the config, the interface is just so painful (laggy touch screen or confusing buttons). The mapping is hard to follow.
Not that Strava mapping on a phone is any better. Why can’t Strava put arrows on the direction of travel?
Sounds like the perfect use-case for big-small processors. A power-sipper for routine 99.99% of operations and a more powerful beast for the CPU intensive ops.
It's mostly because Garmin wants to maximize profits by sticking to old CPUs. The Coros watches (from what I've heard, the same applies to Suunto and Polar) are fast.
This has been an issue across the whole Garmin product line. E.g. the Garmin eTrex 32x from 2019 still used the same CPU as the eTrex 30 from 2011. 8 years without a CPU update. And the eTrex was already had miserably slow map rendering in 2011 with maps from that year.
Although Coros watches are fast, the Coros DURA bike computer is pretty slow when re-rendering maps. Naturally, companies can still choose between how fast the CPU is versus how long the battery life is (100+ hours on the Coros DURA I believe).

I see people riding bikes worth tens of thousands regularly. They should try a top tier models and see what happens.

Yes, this ships in basically every smartwatch since the Snapdragon Wear 3100 launched in 2018.
I think they meant watches that can show actual maps, not just a line or arrow with your route. That feature has always been reserved for the more expensive watches.
The more expensive watches (Fenix) also have long battery lives: lasting up to a month on a battery that can fit in a watch. The processors still have to sip power.
The Coros watches are less than half the price, have 22 days of battery life in smartwatch mode (in the Nomad) and render maps extremely fast. If they added solar, they could probably also last a month (the Coros Apex 4 does 24 days, also without solar).
The funniest thing is that earlier versions of the Coros even used the Garmin map format (though as many small files and not a single/small number of .img). Though they have switched to the open PMTiles format in later versions.
BTW, I had a Fenix 7x solar (before a Fenix 8 AMOLED) and it would usually 'only' last about two weeks. I think you can only reach Garmin's stated time if you disable a lot of functionality.

A modern powerful MCU should be able to do both due to advanced power saving modes. Or youcan even have a power MCU and very low power standby MCU.
This is correct. There are a number of excellent asymmetric multicore MCU platforms now. You don't have to choose between efficiency and performance today.
How do you like the Instinct 3 Solar? I'm considering one for the exceptional battery life.
