How do I recognize when shopping if a laptop graphics card is onboard?

I need to study a laptop with a graphics card that has min 2 Gb VRam and not on-board system Ram uses.

Now I do not want to get a 1k Euro laptop but stay as cheap as possible. But if I'm in the 200-400 euro price class I can never see which graphics cards meet the conditions

You should then google for the laptop model datasheet to find out. Do not trust any statement from sellers.

So I can't answer the first question for sure, but here's a pro-tip:

If you want to stay as cheap as possible, make sure you get one out of the 2nd hand, because under 400 you will not really find much except stinking and annoying with the device.

I also did it and do not regret it, of course you have to somehow make sure that the device is synonymous in order, so if possible test locally before buying

On the datasheet. You look best on Geizhals.de, there you can also filter that a dedicated graphics card was installed

Many Thanks
Geizhals.de was really helpful
