> there are just so many people who say they have an “i5” or “i7” without knowing what generation it is from.

Since switching to laptops from building my own PCs from parts I stopped following CPU models directly. I knew i3 was "weaker" than i5, and i5 "weaker" than i7. But remember getting an "i5" 10 years and they are still selling them. Shouldn't it be up to i15 by now? It would have been better to have some suffix or prefix letters "Pro", or "Super" to indicate tiers.

BMW is also still selling the 5 series.

Cars don't double in performance over the course of five years.

[speedgoose]

The BMW i3 when from 22kWh to 42kWh in a few years but that’s a bit the exception.

kWh is measure of battery capacity not performance.

[fulafel]

It's a dimension of performance, like many others. But lifecycle CO2 footprint is currently the most important performance metric of cars from the holistic pov.

[speedgoose]

Yes, battery capacity is the main thing when you compare early EVs. I think the amont of energy the battery can generate and how fast the car can drive a long distance does fit the performance definition, but I agree it’s not the classic definition of comparing the speed on a tiny segment.

On short distances, the 22kWh version is actually a bit faster because the battery is slightly lighter.

BMW 5-series with an ICE engine vs BMW i3 EV. Apples and oranges.

[speedgoose]

Both are fruits you can eat.

Well, they're selling the ~ 2022 BMW 5 Series or the 20223 BMW 5 series. The year is part of it. That's not the case for CPUs.

Intel also has the generation number in the model number. Honestly I don't think they need i3/i5/i7.
