In chrome dev tools, what is the speed of each preset option for network throttling?

Google Chrome Problem Overview


Since a recent update to chrome, the presets are no longer labelled with bandwidth. bandwidth presets

Chrome used to list the actual speed of each one so you could simply tell.

What bandwidth or latency do the options here represent?

I did some measurements with two speed tests available in the internet. With the following custom profile I received similar download speed and ping latency as with the presets.

Slow 3G Custom: Download 376 kb/s, Latency 2000 ms
Fast 3G Custom: Download 1500 kb/s = 1.5 Mb/s, Latency = 550 ms

The actually download speed measured via the speed tests was only slightly below the configured values. The measured ping latency was half of the value configured in the custom profile.

Here is a csv of the values in the screenshot from Robroi2000's answer

Preset,download(kb/s),upload(kb/s),RTT(ms)
GPRS,50,20,500
Regular 2G,250,50,300
Good 2G,450,150,150
Regular 3G,750,250,100
Good 3G, 1000,750,40
Regular 4G, 4000,3000,20
DSL 2000, 1000,5
WiFi 30000,15000,2

From Chrome DevTools’ source code, here are the presets:

/** @type {!Conditions} */
export const OfflineConditions = {
  title: Common.UIString.UIString('Offline'),
  download: 0,
  upload: 0,
  latency: 0,
};

/** @type {!Conditions} */
export const Slow3GConditions = {
  title: Common.UIString.UIString('Slow 3G'),
  download: 500 * 1024 / 8 * .8,
  upload: 500 * 1024 / 8 * .8,
  latency: 400 * 5,
};

/** @type {!Conditions} */
export const Fast3GConditions = {
  title: Common.UIString.UIString('Fast 3G'),
  download: 1.6 * 1024 * 1024 / 8 * .9,
  upload: 750 * 1024 / 8 * .9,
  latency: 150 * 3.75,
};

For anyone who is wondering how much time it will take to download/Upload 1 MB on connections, following are the results base on Roboroi's Screenshot

Time to download 1 MB

(1MB = 8Mb = 1024 Bytes = 8192 bits)

CONNECTION TYPE                       DOWNLOAD_TIME      UPLOAD TIME

Regular 2G (250Kb/s⬇ 50Kb/s⬆) ->       33s                163 (2m 43s)
Good 2G (450Kb/s⬇ 150Kb/s⬆) ->         18s                54s
Regular 3G (750Kb/s⬇  250Kb/s⬆) ->     11s                32s
Good 3G (1Mb/s⬇ 750Kb/s⬆) ->           8s                 11s
Regular 4G (4Mb/s⬇ 3Mb/s⬆) ->          2s                 3s
Wifi (30Mb/s⬇ 15Mb/s⬆) ->              0.27s              0.53s
