CPU Performance

The Celeron N3150 is positioned as the Braswell-equivalent of the Bay Trail Celeron N2930 found in the ML100G-10 but it seems that the change in architecture is not noticeably beneficial. In our tests, the two chips ran pretty much neck and neck though the N2930 does have a slight edge in clock speed. It's competitive with other entry-level embedded processors but even a basic Core i3 whips it in most situations. Interestingly, the i3-3217U actually defeats the N3150 soundly in video encoding, a multi-threaded task where one might expect that two additional physical cores would the Braswell chip enough of a boost to beat the Hyper-threaded, dual core Core i3.

The pairing of the N3150 with an SSD makes the system fairly responsive and it's sufficient for most basic tasks, even for those used to powerhouse desktop systems, though any demanding jobs will take a whilee to complete.

To compare overall CPU performance, an equally-weighted score has been applied to each CPU benchmark, with a total of 100 points being assigned to the CL100 as a reference point.

In our test suite, the N3150 is actually slightly slower overall the N2930. It's possible that the N3150 is actually a faster chip and that its benchmark times were skewed by the operating system. All our comparison data is from systems running Windows 7, while with the CL100, we were forced to use Windows 10 due to issues with the USB driver. It's supposed to work with Windows 7 if the driver is integrated into the image but we were unable to get USB working once Windows had finished installing, which meant no keyboard or mouse support.

GPU Performance

The N3150 is actually equipped with a much more capable integrated graphics chip than most of the competition. The GPU is based on the same architecture as Broadwell (HD Graphics 5xxx) and sports 12 execution units (EUs) compared to just 4 EUs for the N2930. It scores twice as high as the older chip in our synthetic benchmarks, putting it a stone's throw away from the Core i3-3217U which features 16 EUs on the older Ivy Bridge architecture. It's still not a great choice for gaming but does much better in this regard than older Celerons.

SSD Performance

A quick test with CrystalDiskMark reveals that the 256GB Transcend MSA370 solid-state drive's performance is significant improvement over the smaller 128GB model in sequential and random performance with large block sizes. This is great for copying files but the daily usage pattern of an OS drives involves small block read/writes, so they're more indicative of real world performance. In this regard, the MSA370 just can't keep up with popular consumer SSDs like the the Crucial MX100 and Samsung 850 Pro. The I/O is still very fast but the Samsung 850 Evo, offered as an option with the CL100, seems like a superior alternative.
