Someone over in Dell's marketing department let the cat out of the bag a little early, then tried to stuff if back in. According to VideoCardz, the product page for a refreshed Dell XPS 15 9650 went live for a short time yesterday before someone replaced it with a generic placeholder. The now-absent spec sheet showed some predictable information, like the replacement of Skylake CPUs with Kaby Lake models. The now-gone product page had a bonus nugget, just in time for the holidays: the laptop will sport the as-of-now-unannounced Nvidia GeForce GTX 1050 mobile graphics card with up to 4GB of graphics memory.
Nvidia's Pascal-based mobile graphics chips have proven to be potent performers, but the company's GeForce GTX 1060 is the least-expensive mobile model released so far. The green team has been silent about a mobile variant of the GTX 1050, but its a release seems like a sure thing by now. Digitimes claims that Nvidia has plans to demonstrate laptops with mobile GTX 1050 variants at the Consumer Electronics Show in early January, so Dell's temporary debut of the XPS 15 spec sheet is a little premature.
As for the laptop's other aspects, Videocardz says that CPU choices will include Intel's Kaby Lake seventh-generation Core CPUs in i3-7100HQ, i5-7300HQ, and i7-7700HQ flavors. A 15" 3840x2160 display will reportedly be on offer, likely as an option above more affordable and battery-friendly choices.
The existing mobile GTX 10-series chips have seen few performance cuts compared to their desktop brethren, so it seems unlikely that the already-power-efficient GP107 chip in the desktop GTX 1050 and GTX 1050 Ti will be mangled too badly by the world's tiniest chainsaw before going into laptops. Pricing and availability for the Dell XPS 15 9650 were not released, but we would expect more information on that front during CES.
