What is cloud gaming?
Cloud gaming means the game itself isn't running on anything you own. It's running on powerful hardware in a data centre somewhere, and what streams to your screen is a live video feed of that game being played remotely.
How it works
Your button presses travel up to that server. The server processes them and renders the next frame. That frame streams back down to you, all in the time it takes to blink.
Why cloud gaming is different
With a normal game, your console or PC does the heavy lifting. Your internet plays a role, especially for online multiplayer, but the game itself renders locally. If your connection wobbles, you might see some lag, but the game keeps running.
Cloud gaming flips that: the game runs on a server somewhere else rather than your lounge room.
There's no fallback
Every frame is rendered remotely, compressed, and streamed to your screen in real time
Every button press travels to the server before anything happens on screen
If the stream breaks, the game breaks with it
As far as your device is concerned, there's no game, just a video feed of one. Your connection isn't a background factor here… it's, well, everything.
nbn® 100 vs. nbn® 500: the choice is already made for you
nbn® 100 doesn't really mean 100 Mbps anymore for most people. Back in September 2025, nbn® Co pushed FTTP and HFC connections up to nbn® 500, free of charge. Still on real nbn® 100 speeds today? You're on FTTN, FTTC, FTTB or Fixed Wireless, these are the connection types that missed out on the bump.
How much bandwidth does cloud gaming use?
For cloud gaming specifically, nbn® 500 gives you far more bandwidth than any single session requires. Even GeForce Now streaming 4K at high frame rates only needs around 45 Mbps. One cloud gaming session doesn't come close to filling a 500 Mbps connection.
nbn® 1000 earns its keep when other things are happening at the same time, like:
Someone streaming 4K in another room
A device backing up to the cloud mid-session
A housemate downloading a 100GB game update
Your household's total load decides whether your session stays smooth, not the cloud gaming on its own.
Latency vs. bandwidth: why you need both
This is the part most speed-focused marketing skips, and it's the single most important thing in this blog. For cloud gaming, latency carries as much weight as bandwidth. Often more.
Bandwidth is basically what decides your picture quality, so if you've got plenty of it, you get a crisp 4K picture, and if you don't, things start looking blurry and compressed.
Latency is how quickly your inputs reach the server, and the response gets back to you. It sets how responsive the game feels.
A connection with heaps of bandwidth but poor latency still plays badly. That fraction-of-a-second gap between pressing a button and seeing it happen wrecks anything fast-paced. A 50 Mbps connection with a steady 15 ms ping can beat a 500 Mbps connection with an 80 ms ping. No amount of extra bandwidth fixes a laggy round-trip!
