Best answer: The 9380 model is no longer sold new by Dell since the newest revision, but the 7390 is still available and is now even better value.
Decent value: Dell XPS 13 7390 (From $830 at Dell)
Dell XPS 13 7390 vs. XPS 13 9380 specs
9380 not sold by Dell anymore
As Dell has recently refreshed the XPS 13 again, the older 9380 model is no longer sold new. You may be able to find one through some third-party retailers or even as a refurb, but unless the price is significantly lower, it remains a less recommended buy than either the 7390 or the brand new 9300 model.
Significantly better hardware
In this case, considering the new model against the older one is a simple affair. The refresh is entirely internal, with the same design on the outside accompanying the same great displays and incredibly compact form factor. 1080p touch and non-touch displays are on offer, as is a 4K touch panel, and you still get super-fast PCIe SSD storage on all spec levels of the new model.
Where the most significant difference lies is in the use of the new 10th Gen Intel Comet Lake processors. These aren’t quite as powerful as the Ice Lake processors in the XPS 13 2-in-1, most notably lacking the new Iris Pro graphics. However, they’re still a double-digit performance improvement over the previous generation. Considering the last model XPS 13 used 8th Gen processors, that’s a decent jump to get from the 7390.
Besides a better performing processor, 10th Gen also brings with it support for the new Wi-Fi 6 standard, which the XPS 13 7390 makes use of.
Other small improvements on the 9380
Besides the 10th Gen Core i3, i5, and i7 processors you now get to choose from, there are some smaller, more subtle improvements on the 7390 that make it worth getting. While it still only supports LPDDR3 RAM thanks to the Comet Lake limitations, it’s now faster RAM at 2133 MHz compared to the 1866 MHz you got from the old model. The performance increase is small, but it’s still a performance increase.
