Multi-Core is designed to improve performance of certain software products. Not all customers or software applications will necessarily benefit from use of this technology. 64-bit computing on Intel® architecture requires a computer system with a processor, chipset, BIOS, operating system, device drivers, and applications enabled for Intel® 64 architecture. Processors will not operate (including 32-bit operation) without an Intel® 64 architecture-enabled BIOS. Performance will vary depending on your hardware and software configurations. Intel's numbering is not a measurement of higher performance.
Not available with Intel iAMT (*Not available with vPro)
Processor speed denotes maximum performance mode; processors will run at lower speeds in battery optimization mode.
Chipset integrated with processor
  • Integrated: Intel HD* Graphics 5500
  • Discrete: AMD Radeon R7 M260X, with 1 GB dedicated DDR5 video memory**
*HD content required to view HD images.
**AMD Dynamic Switchable Graphics technology requires an Intel processor, plus an AMD Radeon discrete graphics configuration and is not available on FreeDOS and Linux OS. With AMD Dynamic Switchable Graphics technology, full enablement of all discrete graphics video and display features may not be supported on all systems (e.g. OpenGL applications will run on the integrated GPU or the APU as the case may be).

  • 256 GB M.2 PCIe Solid State Drive
  • 512 GB SATA-3 Solid State Drive
HP 3D DriveGuard (Windows only)
HP 3D DriveGuard mitigates the risk of hard drive failures, safeguarding your data when you are on the go by sensing sudden movement and protecting the hard drive. The hard drive is mounted directly to the notebook frame, reducing the transmission of shock to the hard drive.
*For hard drives and solid state drives, GB = 1 billion bytes. TB = 1 trillion bytes. Actual formatted capacity is less. Up to 16 GB (for Windows 7) and 30 GB (for Windows 8) of system disk is reserved for the system recovery software.
Flash cache
  • 32 GB M.2 (NGFF)
  • Optional 32 GB M.2 flash cache module support for Intel Smart Response Technology installed in the factory.
Available only with standard non-SED hard drive and non-solid state drives.
  • DDR3L SDRAM (1600 MHz)
  • Two SODIMM slots supporting dual-channel memory
  • 4 GB Total System Memory (4 GB x 1)
  • 8 GB Total System Memory (4 GB x 2)
    (Not available with Windows 7 Professional 32)
  • 8 GB Total System Memory (8 GB x 1)
    (Not available with Windows 7 Professional 32)
  • 16 GB Total System Memory (8 GB x 2)
    (Not available with Windows 7 Professional 32)
Upgradeable to 16 GB with optional 8 GB SODIMMs in slots 1 and 2*
Maximized dual-channel performance requires SODIMMs of the same size and speed in both memory slots.
* Maximum memory capacities assume Windows 64-bit operating systems or Linux. With Windows 32-bit operating systems, memory above 3 GB may not all be available due to system resource requirements.
Due to the non-industry standard nature of some third-party memory modules, we recommend HP branded memory to ensure compatibility. If you mix memory speeds, the system will perform at the lower memory speed.
Networking and Communications
