Yet that i5 will be way faster than whatever ARM is in Galaxy. It will also have much faster SSD than the eMMC in phones, and will be paired with faster RAM to boot.

All these things take way more energy, so your laptop will also have much bigger battery.

The phone with 4G will not be subjected to stupid corporate firewall rules preventing access to, say, StackOverflow.

Unless your phone was issued by your employer, is managed by MDM and runs all the traffic through your employers firewall anyway.

On the other hand, there are laptops, that have cellular radios. My old Thinkpad surely does.

Some exception cases: the phone needs to run a Mobile device management agent that installs and launches an antivirus, or the mobile happens to connect to a corporate VPN that routes all traffic and then inspects it via some appliance.

I'd just activate the hotspot on the phone to use the laptop.

I guess they like hiring more devs to do less work.

Frankly, 10k rows is something that an IBM PC from 1985 should have handled adequately, using SuperCalc.

Depends on what you're doing with these 10k rows, though.

FYI GHZ isn't a good indicator of performance difference between 2 different types, models, and architecture;

it's like comparing the revs of your cars, it's just the cycle rate, not the Instruction rate

x86 GHz != ARM GHz

Well, GHz is GigaHerzs or 10^9 cycles/second.

So Ghz is Ghz regardless of x86 or ARM as thisvis just the clock speed.

Another discussion is how much work is done each cycle. For that you might use GigaFLOPS or TeraFLOPS (10^9 or 10^12 dloating operations per second) or another absolute measure of performance.
