The Dell Latitude 13 7390 2-in-1 Review
by Brett Howse on April 12, 2018 8:00 AM ESTGPU Performance
As a business laptop, gaming performance isn’t going to be a priority, and with the Intel UHD Graphics 620, that’s a good thing. The GPU does what it needs to for office scenarios though, with great media playback capabilities, low power usage, and support for three monitors.
Since this laptop isn’t aimed at gaming at all, we’ll just look at a couple of synthetic tests.
3DMark
GFXBench
There’s not much to say about the integrated GPU that’s not already been said. Intel’s integrated GPU is fine for desktop tasks, great for media playback, and improving year-over-year, but only able to be leveraged in 3D situations in the least stressful situations.
Storage Performance
The one area where the Spectre and Meltdown patches have really impacted performance is in I/O, so storage performance is impacted heavily, especially high numbers of reads and writes. As of this writing, the Dell unit is patched for Meltdown, but not Spectre v2, but as we saw in our performance testing of the patches, the Meltdown fix has the biggest impact for I/O.
Dell also offers several choices for the SSD, with a 128 and 256 GB SATA option, or 256 / 512 / 1024 GB NVMe. This model has the 512 GB NVMe, which is the PC401 SK Hynix in this particular unit.
Performance is still quite strong, with read speeds that can reach up to over 2600 MB/s, but write speeds are well behind the fastest NVMe drives on the market.

128gb SSD on the high model? Thought it was a joke until I went to Dell's site.crimson117 - Thursday, April 12, 2018 - link
Seriously, it's like a $40 difference from 128GB to 256GB for basic M.2 SSD's! Dell's charging $110 for the upgrade.IntelUser2000 - Thursday, April 12, 2018 - link
Companies like Dell make money on upselling, that's why they sell it for much more than otherwise. PC market is a very mature market with cutthroat margins.iter - Thursday, April 12, 2018 - link
Don't worry, as long as it is easy to open the unit, you can put whatever drive you want in and it will come out cheaper than buying it from dell.I supposed the 128 gb is a typo tho. Someone copy-pasted and forgot to update the value.
At any rate, it will be better to buy the least storage option and replace it yourself.

Don't worry, if you need more storage they'll gladly sell upsell you to the XPS series for an arm and a leg more.stgs - Thursday, April 12, 2018 - link
What about coil whine? I was about to buy the new 7490 but since reading about the coil whine is still present in 7390 I'm having second thoughts.UltraWide - Thursday, April 12, 2018 - link
I have an hp spectre x360 15t and it has coil whine. I read that it may have to do with the cpu power delivery unfortunately...IntelUser2000 - Thursday, April 12, 2018 - link
Please include the weight of the laptop. It's very important! I don't care much about thickness after a certain point, but weight can go as low as possible. Especially in a 2-in-1.Dr. Swag - Thursday, April 12, 2018 - link
