Not reaching expected speeds via Ethernet cable

Just moved into an apartment that has Google Fiber as an option (speedtest shows 1GB download, ~900MB upload) and when downloading anything on Steam, I max out around 150 MB/s. This is confusing because my roommate (who is on wifi for both PC and console) is seeing 200-400 MB/s when downloading.
I assumed it was a faulty Ethernet cable, so I bought another to test, but I'm still getting the same speeds. I've updated my LAN drivers, but was still met with the maximum of 150 MB/s. I checked CrystalDiskInfo to see if any of my SSDs are dying, but both has a clean bill of health. Any idea what could be going wrong?

Thank you all for the comments, my roommate was confusing bits with bytes, thus confusing me. We have two different work schedules, so I haven't been able to take an actual look at his download speeds. This is both our first time having internet this fast lmao, seeing speeds like this is wild

Assuming this isn't a conversion of bit/byte issue.... Make sure you disable Killer Network service if you have that installed or any other form of "network enhancing" software bloat. My friend went from 200Mbps to 600Mbps after disabling Killer Network. No idea why those services come installed on prebuilds when it makes the PC shitty.

Check out fast.com, it will give you a good measurement in megabit bits per second.

I think you are confusing bit and byte.
1 Byte = 8 bit
So your Gigabit LAN can roughly do 1000 Megabit per second or 120 MegaByte per second.
The difference is normally denoted in using a small letter b for bit and a large letter B for Byte.
So 1000 Mbit/s = 120 MB/s.

Are you aware there are 8 bits (lower case b) in a single Byte (upper case B).
400MB/s would mean you have gigabit ethernet running and 3.5Gbps internet. Your roomate's speeds don't sound correct.

to your point, Steam download speeds are shown in bytes per second, for whatever reason. Most other applications measure download speeds in bits per second.

Most download speeds I've seen are displayed as Bytes TBH, or any time data transfer speeds are displayed. I only see bits for measuring internet speeds.
This is also a setting in Steam you can change btw
Steam > Settings > Downloads and toggle on "Display download rates in bits per second"

MB/s and mbps are different, about 8x different.
150 * 8 = 1200 mbps, which also doesn't make sense unless you're talking about solely write speeds. Since you can be downloading compressed data and it could be writing more than it downloaded due to that compression.
As for your roommate, 200-400 mbps makes sense, 200-400 MB/s does not.

1 Gbps = 125 MB/s.

As the others have said. I suspect this comes down to a misunderstanding on internet speeds vs data transfer speeds being in different (but similar sounding) units.
One is megabytes one is megabits (or gigabits and megabytes etc etc)

MB/s or Mbps?
