Lenovo ThinkPad X1 Carbon 6th Gen: Storage, Productivity And Content Creation Tests

To start things off and to get a sense of how the new ThinkPad X1 Carbon's storage components perform, we fired-up ATTO for a quick sanity check on sequential disk transfer speeds across various file sizes with both read and write workloads.

The 1TB Samsung NVMe SSD in our X1 Carbon is a real speedster, delivering a maximum of 2.7GB/sec of throughput for reads and 2.4GB/sec for writes, and this is with a partially utilized and active OS volume in Windows 10. The drive in this machine is essentially a Samsung 960 Pro, and an excellent choice by Lenovo for delivering a responsive experience. On a side note, the X1 Carbon's wake from sleep (when you lift the lid up after dropping it down but not powering down) is completely instantaneous. It's rather impressive, actually. 

Geekbench And Cinebench 

We kicked off our general purpose benchmarks with a general purpose, cross-platform CPU compute benchmark called Geekbench, and then ran Cinebench R15, a 3D rendering benchmark that tests both the CPU and GPU engines in the processor. Cinebench is developed by Maxon, which is better known for its Cinema 4D software employed in professional 3D rendering and animation studios. We use both of Cinebench’s integrated tests for CPU and GPU.

Surprisingly, the ThinkPad X1 Carbon's Core i7-8650U quad-core CPU doesn't quite catch Dell's XPS 13 with its slightly lower-clocked i7-8550U processor, nor even the 8250U in the Acer Swift 3, when it comes to multi-core throughput in Geekbench. The X1 Carbon does, however, show prowess in single core boost with handily the top score in that test.

In Cinebench, the 2018 ThinkPad X1 Carbon 6th Gen machine pushes higher up the stack of staunch Intel 8th Gen Core-powered competition. It didn't consistently catch the 2018 Dell XPS 13 but it was very close. However, we will note that we observed a fair amount of throttling with Cinebench and the 2018 X1 Carbon at its Windows default setting of balanced performance versus best battery life, with notable variances between multiple successive runs of the benchmark. However, if we cranked the Windows Power Mode slider to max and let the machine's fans spool up slightly higher, that throttling was minimized significantly, and at an only modest and non-offensive increase in fan noise.

PCMark 10 Benchmarks

Next, we'll move from pure content creation in Cinebench, to productivity and mixed usage with PCMark. We're representing all tests from the PCMark 10 benchmark suite, including the Essentials, Productivity, Digital Content Creation and and total PCMark score. The Essentials test covers workloads like web browsing, video conferencing and app start-up times, while Productivity tests everyday office apps from spreadsheets to word processing. Finally, Digital Content Creation tests performance of a machine with respect to photo and video editing, as well as rendering and visualization workloads.

Though the ThinkPad X1 Carbon 6th Gen machine drops into the 4th place slot here, it does score top numbers in the Productivity and Content Creation tests, likely due to its robust Samsung SSD-based storage subsystem. Regardless, among the top four systems in this benchmark, it's very tight race and what could be considered a virtual dead heat.
