Dell confirms XPS 15(7590) will not have the DPC latency

The delay procedure Call (DPC) is a mechanism of the Microsoft Windows operating system that allows high-priority tasks such as interrupt handler latency to be performed later with the low-priority tasks required. This allows device drivers to perform high-priority parts of their processing faster with other low-level event consumers, scheduling non-critical attachment processing to be performed later at a lower priority. One of the main culprits of the XPS 15 9570 is ACPI.sys, which causes audio intermittent failures when playing music.

Dell has reduced latency by releasing BIOS 1.10.1, which has yet to eliminate peak latency. Now, Dell has promised that the upcoming XPS 15 7590 will not have the same DPC latency issue as its previous generation.

It is reported that at the Taipei computer show just past, Dell updated its XPS 15 (7590), the highest support i9-9980HK eight core processor and GTX 1650 graphics card. Now, according to the latest news, Dell's new XPS 15 will go on sale in June.

According to foreign media reports, Dell has confirmed that Dell XPS 157590 will be launched in June, specifically that "XPS 15 will come in the next 2-3 weeks".

The new XPS 15 7590 will be optional OLED screen, SSD is no longer welded on the motherboard, more convenient to upgrade.

In appearance, the new Dell XPS 15 looks a lot like last year's version, unlike the configuration, which supports up to 8 cores\/16 thread processors. The new Dell XPS 15 features an aluminum fuselage, a carbon fiber palmrest and a glass-covered precision trackpad. The low-match version uses the Intel Core i5-9300H four-core processor, at least 8GB DDR4-2666 of memory, at least 256GB of storage space, and a display of at least 1920 x 1080 pixels.
