Arrow Lake is the codename for Core Ultra Series 2 processors designed by Intel, released on October 24, 2024.

[2] Arrow Lake desktop CPUs integrated Thunderbolt 4 and USB4 in the CPU, which allowed it to not waste PCIe 3 lanes and use simple retimers instead.

[3] Integrated GPU added HDMI 2.1 FRL 48 gbit/s (just like mobile Meteor Lake) and variable refresh rate.

[10] On May 20, 2024, Intel reaffirmed that Arrow Lake was on track for a Q4 2024 release with an update promised at Computex in the following weeks.

[11] Arrow Lake is a two-way x86 architecture designed to scale from 28W mobile form factors to 125 W enthusiast desktop segments.

[16] Lion Cove P-cores include support for AVX-512 instructions but AVX-512 has been disabled in Arrow Lake processors due to its heterogenous architecture.

The Skymont E-cores do not feature AVX-512 instructions support so AVX-512 is disabled to ensure that both core types are equal in their capabilities.

[a] SMT, or Intel's marketing term HyperThreading, allows a single physical CPU core with 2 threads to execute two tasks simultaneously.

[20] Skymont E-cores focus on enhanced branch prediction and instruction fetch, increased throughput for 128-bit floating point and SIMD vector data types, and their L2 cache receiving a doubling in bandwidth.

The previous approach required data to travel a longer distance along the ring bus between both core types.

[23] Arrow Lake-S desktop processors feature 4 Xe-LPG cores based on the Alchemist graphics architecture.

However, Arrow Lake mobile processors feature up to 8 slightly modified Xe-LPG+ (Gen12.74) cores which add support for Dot Product Accumulate Systolic (DPAS) instructions.

DPAS instructions were included in Xe-HPG cores for discrete Arc graphics but were disabled in the lower power Xe-LPG variant.

DPAS instructions allow FP16, BF16 and INT4 data types to be multiplied, giving the GPU the ability to perform more operations per cycle.

Alcorn concluded that it is "hard to recommend the Core Ultra 9 285K over competing processors" due to struggling to "keep up with their prior generation counterparts in gaming".

[32] Stephen Walton's three star review for TechSpot found similarly lacking gaming performance with the 285K particularly struggling in Cyberpunk 2077: Phantom Liberty, falling behind the 14900K by 20%, and in A Plague Tale: Requiem where it was outperformed by the 14900K by 17%.

TechSpot observed a that, in gaming, Arrow Lake's power consumption is "much improved over the 14900K" but "the results still fall short when compared to Ryzen processors".

[36] In November 2024, Robert Hallock, vice president and general manager of client AI and technical marketing at Intel, acknowledged that Arrow Lake's launch "didn't go as planned" as gaming performance regression was observed in reviews.

[37] Hallock claimed that Arrow Lake processors suffer from a "series of issues" at both the operating system and BIOS levels.
