New Core HX laptop CPUs from Intel drive computers to 16 cores – Bestgamingpro

An extreme-gaming CPU and one for workstations and multimedia production have been combined into a single 12th generation “Alder Lake-HX” (Core HX) series. The flagship, the Core i9-12950HX, is Intel’s first laptop-optimized 16-core processor, with 8 performance cores and 8 efficiency cores clocked at up to 5GHz.

There is a good chance you will recognize the product name. At CES in January, AMD unveiled their own Ryzen 5900HX CPU, which they dubbed the “world’s greatest processor for gamers.” While Intel isn’t making a comparable promise, the firm is suggesting that this processor will be found in the most intense gaming laptops as part of Intel’s H-series CPUs for enthusiasts.

It was “built specifically for professionals in the field who need low latency access to data for their entire working data set in their computer to do very computational tasks in the field,” according to Daniel Rogers, senior director of mobile product marketing at Intel’s Client Computing Division. While the Intel Core i9-12900HK is “really the world’s greatest gaming CPU” (see PCWorld’s Core i9-12900HK review for additional background), Rogers said that the “HX is a superb gaming processor as well.”

When it comes to single-threaded performance, the Core i9-12950HX is 17 percent quicker and 64 percent faster than the Core i9-11980HK utilizing the SPECint rate base2017 test, respectively. the Asus ROG Strix Scar 17 SE, Gigabyte Aorus 15/17/17X, MSI GT77 Titan, Lenovo Legion 7i, Dell Precision 7670/7770 and HP Omen 17 will all have the HX CPUs.

Basic characteristics of Intel’s 12th-generation Core HX

There are seven processors in the 12th-generation Core HX platform. All of the Core i5-12450HX and Core i9-12900HX processors use 55 watts or less, regardless of clock speed (2.4GHz/4.4GHz (turbo) or 16 cores). That’s a boost of 10 watts above the 12900HK’s output. When running Windows 10 or 11, Thread Director may be used to manage a combination of “performance” and “efficiency” core chips, much like other “Alder Lake” processors. For example, the processor in the Core i9-12950HX operates at 2.3GHz base and up to 5.0GHz turbo with a combination of eight P-cores and eight E-cores for a total of 24 threads.

According to Rogers, Intel customized the desktop Alder Lake chip for the mobile HX family by removing the “lid” off the desktop product and replacing it with a laptop-friendly BGA package instead. According to Rogers, the chip had to be shortened to fit in a laptop with cooling, even if it doesn’t seem like much. Another price must be paid. HX processors don’t have integrated graphics like Intel’s “F”-series CPUs.

All of the 12th-generation Core HX processors are overclockable, including the memory (DDR4 and DDR5), however there are various limitations on specific CPU types.

We can have absolute high frequencies for the highest possible performance and the desktop form factor,” Rogers stated in a taped presentation. For mobile class devices, we use the same CPU arrangement, but we optimize it both in the manufacturing process and in terms of design.

Many were surprised that Intel didn’t provide a processor with an “all-performance core” design. While working with developers like Creative Assembly to optimise games like Total War: Warhammer III to employ both performance cores and efficiency cores simultaneously, Intel enthusiast laptop innovation team member Nick Blair revealed that the firm has worked with the company.

For example, x8 DMI data link between CPU and Platform Control Hub, and 16 lanes of PCI Express 5 (plus four lanes of PCIe 4) out of the CPU are preserved in the HX platform. The PCH has an extra x16 PCIe4 and x12 PCIe3 port. PCIe 5 capability was missing from Intel’s Core i9-12900HK CPU, which the company declared was PCIe 5 compatible but didn’t contain it. Two more noteworthy variations exist.

For starters, the HX platform has two separate Thunderbolt 4 controllers whereas the HK platform has combined them. However, compared to the HK platform, the HX platform offers up to 14 USB2 connections and 10 USB3 ports.

The intended audience, which includes data analysts who want quick, error-free access to data, helps explain some of the variances. The four PCI Express lanes allow for up to 16TB of local storage, which may be stacked in a RAID configuration for additional speed or redundancy. Compared to the HK platform, DDR4-3200 and DDR5-4800 are the only memory choices available (4 DIMMs up to 128GB at 2 DIMMs per channel). Error Correction Code (ECC) memory may also be used.

Intel’s 12th generation Core HX processors

While Ryzen’s R9-6900HX and the i9-11980HK are faster, Intel says its new Core i9-12900HX is quicker even. It’s not clear just how much the corporation is charging, however. Using Blender, CrossMark, and Unreal Engine 5.0, Intel measured the performance of the CPU and GPU, respectively.

The Alder Lake-HX series is unquestionably excellent for gaming. When playing games like as Tom Clancy’s Rainbow Six Siege, the graphics card should provide 400+ frames per second, even though Intel didn’t give comparison statistics.

When it comes to the new HX processor, “we’ve saved the best for last,” Rogers remarked.
