The new XPS 15 2-in-1 laptops from Dell employ Intel's 8th generation 'Kaby Lake-G' processors with Radeon RX Vega M GL discrete graphics which features 4GB of HMB2 memory. The entry XPS model comes with an Intel Core i5-8305G processor, 8GB of DDR4-2400MHz memory, and a 256GB M.2 PCIe SSD for storage. It also sports a 15.6-inch FHD (1920 x 1080) InfinityEdge anti-reflective touch display with support for Dells' Active Pen Stylus and a full-size, backlit MagLev keyboard. The Intel Core i5-8305G model starts at $1,499.99. The higher-end models, on the other hand, use the more powerful Intel Core i7-8705G processor while conserving the exact FHD display and MagLev keyboard. A 256GB M.2 PCIe SSD serves as the primary storage across all models. The Intel Core i7-8705G with 8GB of memory starts at $1,699.99 and the 16GB variant at $1,799.99. And lastly, the XPS 15 with an Intel Core i7-8705G processor, 16GB of memory, and a 4K Ultra HD (3840 x 2160) goes for $2,199.99.

Dell consistently listed the XPS 15's memory as 'integrated'. After browsing through the service manual, we didn't find a section on replacing or upgrading the memory. Therefore, it's safe to say that the XPS 15 (9575) comes with memory soldered to the PCB. This shouldn't be a let down for most consumers as 16GB of RAM is more than sufficient by today's standards. However, prosumers might want to hold off for now until a 32GB SKU is released.
