Apple Mac Air 15" 512GB RAM options

[TomD4P]

I want to look at get the Mac book air 15" with 512GB SSD but I can't find out from the website what the RAM is? I am very sceptical about just 8GB and was hoping it would be more.

I have a high graphics usage. Ive got a couple of macs that are ancient and both run off 8GB RAM. The only issue is CPU load. Sky don't say in the specs, RAM isnt mentioned anywhere?
