HP HSTNN-I92C Battery13/7/2020

The XPS 17’s most impressive performance advantage almost didn’t make it to the final product.
Limited thermal headroom is a problem for laptops in this class. They’re forced to walk a tightrope between heat, noise, performance, and size. The worst example is the 2018 MacBook Pro 15, which infamously throttled the Core i9 so hard it sometimes fell short against the Core i7 model. It was, in a word, a disaster.

According to Oliphant, that’s why the RTX 2060 wasn’t always in the XPS 17’s plans. Simply bringing the thermal solution in the XPS 15 to a larger chassis wouldn’t leave enough headroom for Nvidia’s beefy, 60-watt graphics card. Then, halfway through the development cycle, the team’s engineers hit a breakthrough.

“About six months ago, when we were in the middle of this development cycle, our TDP (thermal design power) for this product was about 70 or 75 watts. Our engineering guys, the thermal and mechanical engineers and architects, developed and incubated a new thermal technique which basically took this product from the mid-70s up to the 90s. We had to change the fans and enclosures a little bit, but no other structural changes to the product. Just through some incubation and innovation on the thermal side, we’re able to give you an extra 30% of TDP.”

This was a breakthrough. Without it, the Dell XPS 17 wouldn’t be “ready for VR,” it wouldn’t have the RTX 2060, and its gains over the XPS 15 would far less impressive. The XPS 17 was well on its way to being another 17-inch laptop serving up a larger display — and not much else.
Dell didn’t offer a specific figure for the boost the new thermal system brings, but more power means the system is able to run higher clock cycles and more efficiently push heat off the system.

The new thermals include a vapor chamber that covers the graphics card and acts as a large heat sink to absorb that hot air. Many gaming laptops use this type of cooling over traditional heat pipes, however. The real breakthrough can be found in the fans.

The impeller is now much larger, filling 90% of the housing with whirling fan blades. Combined with some careful airflow tricks within the chassis of the laptop, this thermal solution can move far more air and exhaust more heat. It sounds simple, but creating a practical, durable fan design capable of such airflow took months of work, and Dell thinks it’ll prove to be a game-changer.

“There’s a ton of different forces pulling us in different directions when we talk about thermal capabilities for these products. I could add some big-ass feet on this thing and drive the thermals up even further. But we want table height when we’re sitting on the table next to our competitors. These aren’t gaming boxes. They’re performance boxes, but they’re premium performance boxes. It’s a delicate balance on what we do to make these things beautiful, but then also make them effective in what their jobs are supposed to be.”

The XPS 17 might not have a clear rival from its Windows competitors, but it does have a clear target. The MacBook Pro 16. It’s a laptop that won much favor for Apple, especially from creative professionals. The XPS 17 has its work cut out for it if Dell hopes to win this “creator” demographic.
“When you look at all the focus on creators right now, a lot of it is marketing,” said Oliphant. “It’s not like there’s been some magical university of creation that has just started people who want to create things. There have always been creators out there. But people have started to market to those people very effectively.”

This is, of course, something Apple has been doing for decades. Apple has always sold itself as the brand for creatives — whether for hobbyists or professionals. The 16-inch MacBook Pro epitomizes this approach as a large and powerful laptop meant for this exact demographic. The 17-inch MacBook Pro was canceled long ago, but the 16-inch feels like its spiritual successor.

The shadow of Apple’s laptop hung over all our conversations at XPS labs. A MacBook sat on the table as we talked about the potential of the XPS 17.
“We didn’t know the MacBook Pro was coming as a 16-inch,” Oliphant told me. “It just happened to perfectly fit right in between our products. Now, we have a sandwich strategy where if you want something lighter and as powerful, you buy this product. If you want something significantly more powerful and probably about the same size, you get the 17.”
