Our Dell XPS 15z review unit has the following specifications:

  • 15.6-inch glossy 1080p display (1920×1080 resolution, 300 nits)
  • Windows 7 Home Premium 64-bit
  • Intel Core i7-2620M dual-core processor (2.7GHz, up to 3.4GHz Turbo Boost, 4MB cache, 35W TDP)
  • Intel HM67 chipset
  • Nvidia GeForce GT 525M 2GB dedicated graphics card
  • Automatically switchable to integrated Intel HD graphics via Nvidia Optimus graphics-switching technology
  • 8GB DDR3-1333 RAM (2x 4GB; max supported)
  • 256GB Samsung 470 Series Solid State Drive (SSD)
  • Intel Centrino Advanced-N 6230 wireless card
  • Integrated Bluetooth 3.0
  • Integrated 1.3MP webcam
  • Built-in slot-load DVD burner (HL-DT-ST DVD+-RW GS30N)
  • Two-year in-home service after remote diagnosis
  • 8-cell Li-ion battery (64WHh)
  • Weight: 5.5 lbs.
  • Dimensions: 15.15 x 10.25 x 0.97 inches
  • Starting price: $999.99
  • Price as configured: $2,059.99

Our test unit is about twice as expensive as the starting configuration of this notebook. Compared to the base configuration we have a 1080p high-resolution display, faster processor, 2GB more RAM, two years of warranty coverage, and of course the 256GB SSD which adds over $500 to the price alone. Without the SSD it comes in at $1,499.99 with a 750GB hard drive.

Performance and Benchmarks
The XPS 15z’s performance as configured is exceptional for everyday usage. I timed system boot-up from pressing the power button to loading the desktop at a mere 15 seconds and the shutdown at 4 seconds. Additionally, the i7-2620M is the fastest dual-core processor available in notebooks. The Nvidia GT 525M dedicated graphics card is more than capable of playing the latest games but not at the highest visual quality settings. Like all of the latest Nvidia graphics cards, the GT 525M comes with Nvidia’s Optimus technology to extend battery life on notebooks with compatible processors and integrated graphics.
