Raptor Lake

Raptor Lake is Intel's codename for the 13th and 14th generations of Intel Core processors based on a hybrid architecture, utilizing Raptor Cove performance cores and Gracemont efficient cores.^[3][4][5] Like Alder Lake, Raptor Lake is fabricated using Intel's Intel 7 process.^[6][7] Raptor Lake features up to 24 cores (8 performance cores plus 16 efficiency cores) and 32 threads and is socket compatible with Alder Lake systems (LGA 1700, BGA 1744, BGA 1964).^[8][9][10] Like earlier generations, Raptor Lake processors also need accompanying chipsets. Raptor Lake CPUs have suffered issues with permanent damage from elevated voltage due to a vulnerable clock tree circuit, resulting in instability. Intel claims these issues have been since fixed in the latest microcode patches, which requires updating the motherboard's BIOS.^[11][12]

History

Raptor Lake launched on October 20, 2022. On January 3, 2023 at CES 2023, Intel announced additional desktop CPUs and mobile CPUs.^[13][14] The 14th generation was launched on October 17, 2023.^[15][16]

In September 2022, an Intel spokesman revealed that Raptor Lake was created to benefit from process improvements before Meteor Lake arrives since the next microarchitecture was likely to be delayed.^[17]

Raptor Lake competes with AMD's Ryzen 7000 series that was launched about one month earlier on September 27, 2022.^[18]

The 14th generation Raptor Lake Refresh is the last processor family to use the old "Core i" branding scheme in use since 2008. The Raptor Lake-U Refresh series is the first processor family to use the new "Core 3/5/7" branding scheme introduced in mid 2023.

On December 14, 2023, Intel announced the Raptor Cove-based Xeon E-2400 series for entry-level servers.^[19]

Mobile processors

All mobile processors except for the HX series support the following types of memory: DDR5-5200, DDR4-3200, LPDDR5X-6400, LPDDR4X-4267. The HX processors only support: DDR5-4800 (DDR5-5600 for i7-13850HX and above), DDR4-3200.

The processors are connected to PCHs using an OPIO 2.0 x8 interface, except for the HX series which uses a DMI 4.0 x8 interface.^[29] Except for the HX series, the processor and PCH are packaged together on a multi-chip package.

The HX series uses 45x37.5mm BGA 1964, and the other mobile processors use 25x50mm BGA 1744, on a Type 3 or Type 4 HDI.

Raptor Lake-HX

The HX processors are desktop processors repurposed for mobile use, with all models unlocked for overclocking.

• CPUs in bold support vPro Enterprise and ECC memory support when paired with the WM790 mobile workstation chipset.
• i7-13650HX and above feature Turbo Boost 3.0, which is at the same speed as Turbo Boost 2.0.
• i9-13980HX supports Thermal Velocity Boost to 5.6 GHz

Instability and degradation issue

An example error message of a program crashing that occur on systems with the affected CPUs, which led to an initial assumption of it being an issue related to graphic cards or drivers^[32]

In February 2024, reports had begun surfacing of users of K-versions of the 13th and 14th generation Core i7 and i9 desktop CPUs commonly experiencing crashing issues in certain workload scenarios, such as video games that use DirectX 12, and HandBrake.^[33][34] The issue was initially attributed to Nvidia GeForce graphics drivers; however, in a driver update published on April 13, 2024, Nvidia acknowledged the instability problem as being associated with the Intel 13th/14th generation CPUs, and that owners of them should contact Intel customer support for further assistance.^[35] Some users and game developers have worked around the problem by applying lower power limits, undervolting or underclocking the CPU.

As of April 18, 2024, according to Intel an investigation of the root cause of the instability issues was underway.^[36] It is believed by some hardware reviewers to be silicon degradation from power limits being set too high by the motherboard's default settings.^[37][38] Shortly thereafter, motherboard manufacturers began rolling out BIOS updates which provide an "Intel Baseline Profile" preset in the overclocking menu, which intends to enforce the power limits of the official Intel specification.^[39] Hardware reviewer Hardwareluxx had found that there is an average performance loss of 9% across a number of applications with the Baseline profile, compared to the motherboard's default profile, when tested using the i9-14900K.^[37]

However, TechSpot found that the Intel Baseline Profile is inconsistent between the motherboard manufacturers (Gigabyte and Asus in particular), with Gigabyte setting a PL2 of 188 W, while Asus sets a PL2 of 253 W which is the official Intel specification. TechSpot further criticized Intel, stating that they had claimed in the past several years that the motherboard manufacturers not adhering to Intel's official specification for power limits were considered normal and "within spec".^[38]

Despite the attempted fix through BIOS updates, instances of crashes still continue to be reported as of July 2024, now largely affecting game server providers equipped with server-grade LGA1700 motherboards. One datacenter service provider reported that it was switching some of its customers to AMD-powered game servers because of the severity of the problems and the lack of prompt fixes.^[40][41] Gaming laptops have also been found to be affected, although to a lesser degree.^[42]

A microcode update fixing a bug with the eTVB algorithm was published the previous month, but this was confirmed by Intel to not be the root cause of the problem, although it may have been a contributing factor.^[43]

Intel confirmed that there is no fix to the issue if it already affects a CPU, and any damage to the CPU is permanent. Intel has decided not to halt sales or recall any units.^[11]

In August 2024, motherboard manufacturers released BIOS updates to fix the issue. Users were advised to apply these updates and use the "Intel Default Settings" in their BIOS configuration.^[44]

In an Intel blog post dated September 25, 2024, the "root cause" was finally acknowledged to be due to a "clock tree circuit within the IA core which is particularly vulnerable to reliability aging under elevated voltage and temperature".^[45]

Two-year warranty extension for certain models

On August 2, 2024 Intel announced they would extend warranty for certain retail (boxed) 13th/14th generation Core CPUs by two years.^[46][47][48] On August 5, 2024 the company announced they would extend warranty to tray (OEM) CPUs as well.^[49] The extended warranty will cover the following models:

Processor model
13th generation Intel Core	14th generation Intel Core
i9-13900KS	i9-14900KS
i9-13900K	i9-14900K

Notes

1. 128 GB by default. A BIOS update must be installed to install 256 GB.
2. Technically dual-channel DDR5 can be considered "quad-channel", as there are 4 × 32-bit memory buses, rather than 2 × 64-bit as is the case with DDR4. See DDR5 SDRAM § DIMMs versus memory chips for more info.
3. Price is Recommended Customer Price (RCP) at launch. RCP is the trade price that processors are sold by Intel to retailers and OEMs. Actual MSRP for consumers is higher.
4. These are likely Alder Lake processors since they do not include increased L2 caches.^[27][28]
