ThinkPad X1 Extreme Battery Life, Acoustics, Thermals And Summary
Since laptop displays significantly affect power consumption and battery life, it's important to ensure a level playing field with respect to
Battery Life - How We Test:
Our custom HotHardware video loop test takes a 1080p HD video with a 16Kbps bit rate and loops it repeatedly, with
Update, 11/8/18: Lenovo reached out and noted that with the 1080p display option of the machine, and using the Windows 10 TV & Movies player, results in about 6 hours up video playback up-time. We'd offer that is a reasonable expectation as well, given this laptop's 80 Whr battery.
Lenovo ThinkPad X1 Extreme Acoustics & Thermals
At idle the Lenovo ThinkPad X1 Extreme is virtually silent and you don't typically ever hear its fans spin up. Under our extended benchmarking, however, we did notice the machine's thermal solution kicking in. That said, Lenovo did an excellent job of engineering both adequate cooling with minimal throttling, along with -- dare we say -- almost pleasant acoustics for this new 15-inch ThinkPad X1 platform. Cooling fan whine can often times not only be an issue in terms of volume or loudness, but also pitch. In the case of the ThinkPad X1 Extreme, fan pitch actually sounds both unoffensive (at least to our ears) and subdued volume-wise. And again, Lenovo achieved this relatively elegant cooling solution along with also delivering excellent thermal management performance overall, bleeding little top-end speed under extended, constant load.
Performance Summary:Lenovo's new 15-inch ThinkPad X1 Extreme delivered impressive performance for its weight class across our myriad of benchmarks, from office productivity to content creation, graphics rendering and gaming. Versus the likes of Dell's XPS 15 2-in-1 or the XPS 15 9570 with GTX 1050Ti graphics, Lenovo's new ThinkPad either slotted in between the two systems or lead them by a hair, depending on the workload. In any event, if you're the kind of power user that needs a light-weight machine with this sort of horsepower, Lenovo's combination of a stout 6-core Intel Core series CPU, coupled with this machine's GeForce GTX 1050 Ti Max-Q graphics engine, fast Samsung SSD, and 32GB of fast DDR4 memory, is hard to beat.
As configured for our review, there's no question you'll have justify the business case (or pleasure, we suppose) associated with a $3100 laptop price tag, but you do have a fair swath of configuration options to choose from, between its base price and our much more top-end review config. Was Lenovo sandbagging our benchmarks here? Maybe just a tad but it is what it is, as they say, and you can dial things back a bit if this config is too rich for your blood. In the end, the Lenovo ThinkPad Extreme is an extremely well-equipped, powerful laptop with a beautiful 4K HDR display option that delivers workstation and enthusiast-class performance levels in a light, 4lb, extremely well-built machine. As long as you don't mind the relatively short battery life of its high-end display configuration, this new, larger 15-inch format ThinkPad X1 variant will handle just about anything anyone would throw at a laptop these days, and do so with grace and agility.
