System Performance

Lenovo offers both Core i5-8250U, and Core i7-8550U options on the Yoga C930, and both are quad-core Kaby Lake Refresh U series SoCs. As with most review units, Lenovo has sent us the Core i7 model to test out. It’s outfitted with 12 GB of DDR4-2400 in dual-channel configuration as well.

The Core i7-8550U caps out at 4 GHz maximum, with a nominal TDP of 15 Watts, but for shorter workloads, the Kaby Lake Refresh can usually draw quite a bit more than that, depending on how the OEM has the power level states configured.

We ran the Yoga C930 through our standard Ultrabook suite of tests, and comparisons will be against similar devices on the market. If you’d like to compare the performance against any other laptop we’ve tested, please check out our online Bench.

PCMark

PCMark 10 - Essentials

PCMark 10 - Productivity

PCMark 10 - Digital Content Creation

PCMark 10 - Overall

PCMark 10 is a comprehensive system test offering several workloads to stress different aspects of a system. The Lenovo Yoga C930 aces these tests, offering some of the highest performance of any Ultrabook without a discrete GPU we’ve seen.

Cinebench

Cinebench R15 - Single-Threaded Benchmark

Cinebench R15 - Multi-Threaded Benchmark

Cinebench is a purely CPU based test, and it offers both single-threaded and multi-threaded workloads. Clearly Lenovo has done a nice job on cooling, because once again the Yoga C930 is near the top against other U series laptops.

This test uses the CPU to encode video, and it performs well with more cores and more threads. This test is also quite lengthy, meaning you’re more likely to run into thermal limits than shorter tests. The Yoga C930 is once again at the top, and by a wide margin here. It’s clearly able to deliver higher power levels without throttling, which we’ll dig into later in the review.

Web Tests

Web tests are important but are impacted immensely by the underlying web browser and its scripting engine. We run all of our web tests in Microsoft Edge, although it is updated several times per year as well, so these results are a snapshot in time.

Mozilla Kraken 1.1

Google Octane 2.0

WebXPRT 2015

Although not quite a the top of these charts, the Yoga C930 still performs admirably. In general use, most web workloads should not be too taxing on this device.

System Performance Summary

We’ll dig into this later on, but Lenovo has provided a laptop that is a class leader in performance, and is able to maintain higher power levels for longer, allowing the Yoga C930 to pull ahead of the competition when the CPU is being stressed heavily.

    Wow, another dismal ips display. Better go TN for such awful results. Reply

    Still better viewing angles for IPS. I've also seen 400:1 contrast ratio even on 1080p TN panels for laptops. Unless you are a hardcore, professional gamer, TN is never worth it. Reply

    It isn't worth it even then. My Samsung CHG27 is great, and it's a VA panel. You really don't need TN at all today. Reply

    While I think VA is the worst panel technology, you are right. TN really doesnt give you much more advantage. Fast IPS displays nowadays are fast enough with their 4-5 ms. And the real important thing for gamers is the input lag, not the response time. Reply

    Firstly lenovo's tn panels are certainly no better. Secondly tn and touch screens are not a great match. Just try pressing on a tn panel and yiu will know. Reply

    The 9260 has Bluetooth 5 according to Intel: https://www.intel.com/content/www/us/en/products/w... Reply

    Lenovo typically makes the disclaimer in their spec sheets: HW supports BT5.0, Windows only supports BT4.1 (or something like that). Reply

    Windows has supported BT5.0 since 1803 update Reply

    Up to the point where he looked at the screen, I would have thought the author had found the love of his life: Superlatives beyond anything I had ever seen here before...

    But at €1800 for the 8/256GB variant and €2300 for the 16/512GB+4K screen I CHUWI over alternatives...

    These things can be mass produced and sold at $800, now that those insane flash and RAM prices are coming back down and Intel is facing competition.

    Unfortunately, Intel's competition is most often not put in a premium chassis and delivered with a sub par configuration with few configuration choices but still at the same price as the Intel counterpart - with the rare exception. Reply
