ThinkPad X1 Yoga Benchmarks: SANDRA And SunSpider
The System ANalyser, Diagnostic and Reporting Assistant, or SANDRA, benchmark suite is an excellent resource for assessing the raw performance numbers a system is capable of. Their database is updated with real world results shared from users around the globe. You can run the entire battery of tests offered or pick and choose as your leisure. For our purposes we query the Processor Arithmetic and Multimedia as well as Memory and Storage Bandwidth tests. These give us a quick sanity check to be sure everything is running as expected.

As we can see, everything is working as intended. These are some of the best numbers we've seen from an ultrabook style notebook aside from storage. It's unfortunate to see a premium notebook in 2016 still using a SATA-based solid state drive when faster PCI-e NVMe drives have become so prevalent. Still, SATA SSDs are plenty fast so we don't anticipate this to be a noticeable bottleneck but if it is really an issue, you can opt for an NVMe drive at the 256 GB and 512GB levels.
The Sunspider website offers the following about their test:
The Lenovo ThinkPad X1 Yoga rips through this time-tested benchmark with no remorse. The Intel Core i7-6500U packed away inside is both quick and responsive and swings well beyond its "U" designation here. Furthermore, we've got a 20% improvement over its spiritual predecessor, the ThinkPad X1 Carbon 3rd Gen, granted that was only packing a Core i5. That's just web-browsing though so let's move on to some beefier number crunching...
