Based on Intel estimates of Lunar Lake on stable diffusion 1.5 with GIMP plugin against Snapdragon X Elite public claims. Generative AI workload with Intel's GIMP plugin and Stable Diffusion: This workload measures the total time in seconds to complete 20 inference steps using the GPU with Intel's GIMP 2.99.14 plugin, which includes Stable Diffusion support via OpenVINO 2023.1. Data in this presentation compares Intel's Lunar Lake reference platform estimates with Qualcomm's public statements on their GIMP Stable Diffusion plugin, noting that Qualcomm's optimizations are unknown.

Tested on Intel Reference Validation Platform (RVP) with Lunar Lake Ultra 5 processor running Windows 11 Enterprise (version 10.0.26100 Build 26100) with 16 GB RAM.

Tested with Gen 4 NVMe 1 TB SSD used behind a Thunderbolt™ 3 dock (with Titan Ridge) and Thunderbolt™ 5 dock (with Barlow Ridge hub) connected to the Lunar Lake RVP.

Storage Read and Write speeds were measured with CrystalDiskMark tool with settings of 5 test count and 32 GiB test size.

Lunar Lake is the first Intel platform to integrate Wi-Fi 7 technology and enable use of PCIe vs. USB interface for integrated Bluetooth® technology routing.

The use of PCIe frees up additional USB lanes for use by PC OEMs and enables improved Bluetooth® initialization and wake times. Intel engineering measurements using a LNL reference validation platform with PCIe-based Bluetooth® showed an average boot time of 0.648 seconds which was approximately 55% lower than the 1.439 seconds required for USB-based Bluetooth® designs.

Similar levels of improvement were measured when comparing PCIe vs. USB Bluetooth® interface wake from sleep times for connected peripherals (Human Interface Devices) in both Classic Bluetooth ~55% (34.355 vs. 75.933 ms) and Bluetooth Low Energy ~56% (32.189 vs. 74.098 ms) modes.

PC platform DDR memory can operate at many of the same frequencies as the 5 GHz and 6 GHz channels used by Wi-Fi technologies.

When DDR frequencies interfere with Wi-Fi on these channels, the throughput degradation can be as high as 8 dB or about 50% lower, based on measurements by Intel platform engineering teams.

Lunar Lake platform Wi-Fi integration enables Radio Frequency Interference Mitigation (RFIM), which coordinates simultaneous platform memory and Wi-Fi operation.

DDR RFIM dynamically moves memory speed to clear the connected Wi-Fi channel from memory narrowband noise and helps avoid the potential Wi-Fi performance impact from DDR memory operating on the same frequencies.

A typical Wi-Fi VR setup to a PC with a standard single-radio Wi-Fi card requires the HMD to make 2-hops and go through the router to access the PC, which adds latency to the user VR experience.

High-end gaming PCs with premium dual-radio Intel® Killer™ Wi-Fi 6E AX1690 cards are able to dramatically reduce latency for wireless VR gaming using Intel® Double Connect Technology. This solution uses one Wi-Fi radio for the PC-HMD VR connection and a second Wi-Fi radio for the PC-router connection, allowing the Meta Quest headset to bypass the router for direct wireless access to PC games, resources, and Intel® Killer™ Networking software. To deliver the high-quality Wi-Fi connectivity that the Meta Quest HMDs need, working closely with Meta, Intel has enabled laptops configured with its connectivity software and Intel® Wi-Fi 7 (5 Gig) cards to deliver 1-hop single radio Wi-Fi PC VR performance that was similar to the high-end gaming PCs with its dual-radio Killer solution.

Intel-Meta VR tested these three Wi-Fi PC VR configurations using 80 MHz channels in the 5 GHz band. In clean environments without channel contention and in a challenging environment with 70% channel contention, the 1-hop dual-radio solution enabled a -30% / -55% reduction in latency, and the new 1-hop single-radio solution enabled a similar -27% / -50% reduction compared to the standard 2-hop configuration.
