▲ Processor specifications
In terms of chipset, HM55 has replaced PM55 as a close partner of the new Core processor. Like PM55, HM55 chipset development code is Ibex Peak-M. Like the previous mobile chipset based on desktop chipset, HM55 chipset is also derived from H55 chipset on desktop. Unlike PM55, which only supports i5 and i7, the new HM55 chipset was introduced by Intel to match the new processor with built-in graphics processing unit, which can provide comprehensive processor support. HM55 also adopts single-chip architecture, and the memory control unit (IMC) is integrated in the processor, so there is no MCH (Memory Controller Hub) commonly known as the North Bridge chip. There is only one platform control unit, PCH (Platform Controller Hub), which undertakes the functions provided by the previous PCI Express controller and ICH (Input/Output Controller Hub). Compared with the dual-chip architecture, single chip has more advantages in power consumption and calorific value, which is a good premise to help notebook computers better dissipate heat and improve their endurance. At the same time, in the absence of chips, manufacturers can design the motherboard more compact, which will help make the notebook thinner and lighter. HM55 chipset can also support up to six SATA 3Gbps interfaces (including eSATA), eight PCI-E 2.0 x 1 interfaces, 14 USB 2.0 interfaces, Hanksville GbE MAC gigabit Ethernet controller, Matrix Storage matrix storage technology, high-definition audio and high-definition audio, and management engine ignition firmware technology.
▲ Discrete graphics card specifications
Dv3-4044TX adopts the combination of ATi Mobility Radium HD 5450 discrete graphics card and Intel Graphics Media Accelerator HD integrated graphics card built in Core i5, and the two graphics cards can be switched dynamically. ATI Mobility radium HD 5450 is the equivalent product of ATi Mobility radium HD 5470, a mid-range independent graphics card which is widely used at present. Based on 40nm process technology, this discrete graphics card has 292 million transistors, supports the latest DX 1 1, OpenGL 3.2, and upgrades the graphics and memory configuration to GDDR5/DDR3, with 80 stream processors, core frequency of 750MHz, maximum support for 1GB graphics memory, and the number of texture/rasterization units has increased to. At the same time, the power consumption of TDP has also increased, which is 15W when matched with GDDR5 video memory. The graphics card supports DX 1 1, integrates the UVD2 hardware decoding engine, and a series of energy-saving technologies such as PowerPlay, PowerXpress and Swithable Graphics.
▲ Standard memory specifications
As for the storage system, the dv3-4044TX we received comes standard with 2GB DDR3 memory, and the memory is 1 Hynix HMT125S6 TFR8c-H9 2GB DDR 31333 MHz. For ordinary business users running 32-bit operating system, this memory capacity is enough to cope with most mainstream applications and run some large-scale business software applications. Even if running a 64-bit system, this memory capacity can ensure users' smooth use, or improve performance by upgrading memory.
The prototype we received uses Toshiba MK5056GSY 2.5-inch hard disk with a capacity of 500GB and a rotation speed of 7200 rpm, which solves the bottleneck problem of notebook hard disk well and provides a good application foundation for those business users who are pursuing performance. This 7200 rpm hard disk supports SATA-II interface, which can effectively cooperate with PCH to achieve faster 3.0Gbps transmission rate. In addition, in order to better protect the hard disk, HP also equipped it with HP 3G DriveGuard hard disk shock-proof technology, which will automatically stop working when the fuselage is hit to avoid damage to the stored data.
In terms of network communication capability, dv3-4044TX adopts the collocation of Realtek RTL 8168d/81D wired network card and Atheros AR9285 wireless network card. Atheros AR9285 wireless network card can only support 802. 1 1 b/g communication protocol, while RTL 8168d/81d wired network card supports10/100.
