After the four series of h45, P28, U15 and u9, Intel officially launched the top-level sequence of 12 core mobile version "alder Lake HX" (hx55) , which brings desktop luxury specifications to the notebook. The number of cores, frequency, power release, overclocking and so on are unprecedented. Hx55 series is mainly for high-end mobile workstations and fever level game books. It can bring performance comparable to high-end desktops to content creators, engineers, researchers and game players.
Hx55 series is different from other sequences of the 12th generation core mobile version. It is homologous with the desktop K series and directly uses the kernel of the desktop version, 45 × The packaging area of 37.5mm is exactly the same, but in order to adapt to the mobile end, the thickness is reduced from 4.4mm to 2.0mm. In addition, targeted adjustment and optimization have been made in terms of power management and power consumption
It is worth noting that the processor and chipset of hx55 are packaged independently to maximize performance, while the h45 series is an integrated package of the two.
In terms of platform specifications, hx55 series processors have up to 8 performance P cores, 8 energy-efficient e cores (supplemented by hardware thread scheduler), a total of up to 16 cores, 24 threads, and 30MB L3 cache , which are full of blood, while the integrated core displays up to 32 execution units.
The memory supports dual channel ddr5-4800 or ddr4-3200, and can install up to 4 (2 or even 1 ordinary notebook), with a maximum capacity of 128GB, and ECC error correction is introduced. Therefore, it is very suitable for professional fields with high requirements for data integrity.
The expansion connection supports 16 PCIe 5.0 and 4 PCIe 4.0 . The latter is naturally used for SSD, while the former can be used for single or two graphics cards, or half can be removed for SSD. Although only X4 can be used, the bandwidth is also equivalent to PCIe 4.0 X8.
Video output supports HDMI 2.0B, DP 1.4, edbp 1.4b and hbr3, which are similar to h45 series.
The processor is connected to the chipset through PCIe 4.0 X8 DMI channel, which can provide 16 PCIe 4.0, 12 PCIe 3.0, 14 USB 2.0 and 10 USB 3.0 x. Eight SATA 6gbps, Wi Fi 6e (Giga +) , and two independent thunderbolt lightning controllers.
With such rich PCIe channels, the hx55 platform can use up to four SSDs, including one PCIe 5.0 X4 and three PCIe 4.0 x4, with a maximum capacity of 16TB**
Look, four memories and four SSDs are spectacular enough!
At the software level, hx55 has also passed a number of OEM platform certifications, which can ensure the compatibility and stability of professional software such as AutoCAD, Revit and Premiere Pro.
Hx55 series has six different products, covering i9, i7 and i5. The basic power consumption is 33W, and the maximum Rui frequency power consumption is 157w**
The flagship model is i9-12950hx, 8p + 8e, 16 cores, 24 threads, three-level cache of 30MB, p-core frequency of 3.6-5.0ghz, E-core frequency of 1.7-3.6ghz, integrated core display 32 units, frequency of 1.55ghz
*The basic specifications of i9-12900hx * are completely consistent. The difference is that it does not support enterprise vPro and ECC, but it is open to full core overclocking. As long as the notebook heat dissipation allows free overclocking, i9-12950hx preset the overclocking threshold.
*I7-12850hx and i7-12800hx * are similar. They have the same 16 cores, but the L3 cache is reduced to 25mb, the maximum frequency is reduced to 4.8ghz, and the maximum core display frequency is 1.45ghz.
*I7-12650hx * comes to 6p + 8e 14 core 20 threads, and the L3 cache is 24MB. The maximum frequency is reduced to 4.7ghz again, supporting some overclocking.
*I5-12600hx * 4P + 8e 12 core 16 threads, three-level cache 18MB, maximum frequency 4.6ghz, support enterprise vPro, ECC and partial overclocking.
*I5-12450hx * only has 4P + 4E 8 cores, 12 threads and 12MB three-level cache. The maximum frequency is 4.4ghz. The core display is also cut to 16 units, which is partially overclocked.
Speaking of overclocking, hx55 series also inherits many features of desktop K / KF series, and the processor and memory can be overclocked.
Among them, the processor supports energy efficiency core overclocking, speed optimizer and extreme tuning utility , and the memory supports ddr5 MXP 3.0 and dynamic memory boost. Of course, it also depends on the settings of the OEM.
In terms of performance, Intel also takes the high-end i9-12900hx as an example and gives a series of comparative data:
Compared with the top i9-11980hk of the previous generation, the single core performance increased by 17%, the multi-core performance soared by 64%, the 3D rendering performance was up to 81%, the creativity performance of crossmark was also up to 33%, the professional creation performance of Autodesk was up to 12-28%, and the professional performance of specworkstation was up to 45% and 111%
In terms of game performance, with RTX 3080 Ti and 64GB ddr5 memory, a large number of 3A games can easily exceed 100fps. High brush E-sports screens such as 120Hz and 165hz must be matched.
With its unique hybrid architecture design, hx55 is also very suitable for multi task professional creation. For example, can use Unreal 5 engine for game design and rendering at the front end and blender for 3D modeling and rendering at the back end. It is claimed that the performance can be improved by more than 4 times and 1.7 times respectively, saving 79% and 41% of the time respectively**
Behind the realization of this accelerated collaborative work is the credit of the IDT thread scheduler. When multitasking, it will intelligently distribute the workload to the appropriate core.
Intel has also conducted a number of demonstrations. It can be seen that whether it is games, content creation or multitasking, the p-core and E-core have been perfectly utilized and perform their respective duties.
Mobile workstations and game notebooks based on Intel hx55 series will be launched one after another. There will be more than 10 models this year. The first batch includes ASUS Rog Strix scar 17 se (Rog gun god 6 super competitive version), expertbook B6, Gigabyte aorus 17x / 15x, MICROSTAR gt77 Titan, gt77 / gt67 raider, Lenovo Legion 7I, HP omen 17, DellPrecision 7770/7670。**
