Both CPUs were available with either the 445M or the 435M.  The  two systems are different - 445M has four memory sockets -- the 435M only two.

The specs should be listed.

I added an XPS 15 to my basket and this was the information I was given:

No mention of which GPU it has (either the 420M or the 435M).

Sorry for the confusion. I am asking about the XPS 17s, I was just using that particular XPS 15 to demonstrate that the laptops advertised in the Outlet don't always tell you which GPU is fitted.

I made the same assumption that you did; that the i3 XPS 15 would have the less powerful GPU and that the i5 XPS 15 would have the more powerful GPU. But because the XPS 17 can have the i3, i5 or i7 CPU installed you can't make that same assumption. Do you see what I mean?

I thought based on your message header you were asking about the XPS 17, not the 15.  The 15 comes with either the 420M or 435M.  I'd guess the i3 is the lower end one.

I had the same question.  Did you ever find out the answer?

I'm suspicious that, since these are all returned systems, that they may have had problems with the nvidia graphics card, and the fix was just to pull the graphics card and rely only on the integrated Intel graphics.  Then, those GPU-less XPS system get stuck into the outlet.

There are other oddities in the outlet -- occasionally, you'll see an XPS with 3 GP of memory, or an i3 or something.

I believe that the i7s all come with the more powerful GPU and I don't think Dell could get away with selling a product they know to be faulty. Even if they did, Outlet laptops are covered by the same warranty as brand new laptops.

In the end I decided to splash out and treat myself to an MSI GX660R. It's  a beast :emotion-2:

Hope that helps.
