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 launched on October 20, 2022. On January 3, 2023 at CES 2023, Intel announced additional desktop CPUs and mobile CPUs.[11][12] The 14th generation was launched on October 17, 2023.[13][14]
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.[15]
Raptor Lake competes with the AMD Ryzen 7000 series that was launched about one month earlier on September 27, 2022.[16]
On Dec 14, 2023, Intel announced the Raptor Cove-based Xeon E-2400 series for entry-level servers.[17]
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.

- All models support up to DDR4-3200 or DDR5-4800. The i5-13600 (K/KF/T) and all models above it support DDR5 speeds up to 5600 MT/s with max 2 DIMMs slotted, 4400 MT/s if 4 DIMMs are slotted.
- All models provide 28 PCI Express lanes:
- 16 PCIe 5.0 lanes
- 4 PCIe 4.0 lanes
- 8 DMI lanes[18]
- Models without the F suffix feature either of the following integrated UHD Graphics GPUs, all with base frequency of 300 MHz:
- UHD Graphics 770 with 32 execution units, or
- UHD Graphics 730 with 24 execution units
- Max Turbo Power: the maximum sustained (> 1 s) power dissipation of the processor as limited by current and/or temperature controls. Instantaneous power may exceed Maximum Turbo Power for short durations (≤ 10 ms). Maximum Turbo Power is configurable by system vendor and can be system specific.
- CPUs in bold below feature vPro Enterprise and ECC memory support only when paired with a motherboard based on the W680 chipset.[24] Other SKUs do not support ECC memory at all.
Suffixes to denote:
- T - Low power (TDP reduced to 35 W)
- F - No integrated graphics

Issues
editIn February 2024, reports had begun surfacing of users of K-versions of the 13th and 14th gen Core i7 and i9 desktop CPUs commonly experiencing crashing issues in certain workload scenarios, such as video games that use DirectX 12, and Handbrake.[29][30] The issue was initially attributed to Nvidia GeForce graphics drivers; however, in a driver update published on April 13, 2024, Nvidia acknowledged the stability problem as being associated with the Intel 13th/14th gen CPUs, and that owners of them should contact Intel customer support for further assistance.[31] 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.[32] It is believed by some hardware reviewers to be silicon degradation from power limits being set too high by the motherboard's default settings.[33][34] 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.[35] 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.[33]
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".[34]

Notes
edit- ^ 128 GB by default. A BIOS update must be installed to install 256 GB.
- ^ 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.
- ^ a b c d e f g h i j 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.
- ^ a b c d e f g h i j k These are likely Alder Lake processors since they do not include increased L2 caches[25][26]
