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
