Let me see, the 9560 is about 5 years old and the 9510 is 1 year old. The 9560 had a 7th generation CPU, so Windows 11 is not compatible per the MS specs. The 9510 is an 11th gen CPU and is compatible with Windows 11. The 9510 has 2 M.2 slots, compatibility for 64 GB of RAM, RAM specs are for 3200MHz RAM  The 9560 has 1 M.2 slot, 32 GB of RAM, and compatible with 2400 MHz RAM. Needless to say the 9510 far surpasses the performance of the 9560. The 9560 specs are here. And the 9510 specs are here.
Hello, We bought that machine “XPS 15 9560” end 2017, and since 2 years we have changed 3 time our Mother card! We have Support PRO contract Since one month our touch screen is KO, Dell says that now they want to change our machine! Therefore they propose an exchange to the XPS 15 9510. But we need more more explanations. We ask for details and differences between our model and this one, no answer! We ask to keep our hard disk or at least to find out a way to make an image copy of the actual hard disk to the new one, is it possible do not know? We do not want to spend lot of days reinstalling all our software and also for some of them no more the setup! NO answers too! At least we ask to keep the hard disk for some days in order to find a solution and do that image copy, still no answers! Despite lot of calls to the support, get only answer like we will check and call you back no answers too! So you can imagine how we are disappointed about this situation and the Dell support! Just wanted to expose our situation and share your own experiences in such cases. Thanks to all and hope we can get answers not like Dell support!
