We reviewed our first XPS 15 9575 SKU just a few weeks ago and its performance surprised us. Not only are the Core i5-8305G CPU and Radeon RX Vega M GL GPU comparable to the Core i7-7700HQ and GTX 1050, respectively, the thinner XPS 15 9575 even manages to run cooler and quieter than the thicker XPS 15 9560 that it derives from.

For our second look at the XPS 15 9575, we want to see what benefits the Core i7-8705G SKU can bring to the table over the i5-8305G SKU. Both processors are equipped with the same Vega M GL GPU, but Dell is locking both the 4K UHD touchscreen and 16 GB RAM options for the Core i7 configuration only. As a result, our test unit today retails for over $2200 USD compared to just $1500 USD for our original Core i5 XPS 15 9575 unit. Does the extra performance justify the price differential?

We recommend checking out our original review on the Core i5 XPS 15 9575 SKU for more information on the chassis and its features. The XPS 15 9575 is Dell's premier 15-inch XPS convertible and the first with MagLev keyboard keys, GORE insulation, and Kaby Lake-G all in a laptop.
