Typical end-consumer uses are workstations or even high-end business desktops that need to be on all the time and perform some heavy data or GFX-intensive projects (it also requires a GFX card) because high-end XJs usually don’t use a GPU. The low-end E3 series Xeon does have a built-in GPU for enterprise mini-desktops that are usually always on, and remote workers can log in from their laptops via a VPN via a remote desktop client to work with their developer toolkits and so on. Even the laptop-based Xeon is showing up in 2016 (Broadwell Generation), as it did on the Dell Precision 7710.
For high-end servers, IBM Power usually does better than Intel Xeon CPU in most edge situations, especially since IBM servers support faster NVLink protocols and faster RISC CPUs, Each core can run up to 8 threads (Intel Xeon up to 2 threads per core) although the number of cores is higher). In addition, as chips are scaled down to accommodate more cores on Intel, there are still practical and reasonably priced cooling solutions available since not everyone can afford sustainable liquid nitrogen cooling in low humidity environments, but due to power dissipation some more stringent physical limits are imposed on the frequency cap.
