Intel Panther Lake first benchmarks point to a big leap over Lunar Lake, with the flagship integrated graphics posting eye-catching gains and promising better efficiency.
Early third-party tests show the Core Ultra X9 388H scoring up to 6,300 points in 3DMark Time Spy. That result comes courtesy of its 12-core Xe3 “Celestial” iGPU and represents roughly a 45–50% uplift versus Lunar Lake’s Arc 140V. The numbers line up with Intel’s own guidance of around a 50% graphics boost and put the new iGPU roughly on par with the GeForce RTX 3050 laptop GPU. These are preliminary figures, and Arc drivers for the Xe3 architecture are still maturing, so performance could climb further by launch.
What’s inside the Core Ultra X9 388H helps explain the jump. This top-tier Panther Lake SKU uses a 4+8+4 P/E/LP-E CPU core layout paired with 12 Xe3 graphics cores, effectively doubling the Xe core count versus many Lunar Lake configurations. As one of the fastest models in the lineup, its results likely represent the upper bound of what Panther Lake’s integrated graphics can deliver in thin-and-light designs.
There are important caveats when looking across the broader market. While Panther Lake’s Xe3 graphics seem to handily outpace Lunar Lake and show meaningful gains over internal predecessors like Arrow Lake-H, AMD’s latest high-end integrated solutions still hold a lead. Systems based on Strix Halo with the Radeon 8060S iGPU remain ahead in raw iGPU performance, underscoring that Intel’s biggest strides are versus its own prior generations.
Key takeaways:
– Core Ultra X9 388H Time Spy score: up to 6,300
– Approximate uplift vs. Lunar Lake Arc 140V: 45–50%
– Rough performance class: comparable to RTX 3050 laptop GPU
– Architecture highlights: 12 Xe3 “Celestial” iGPU cores, 4+8+4 P/E/LP-E CPU configuration
– Status: early benchmarks with evolving Arc drivers; final performance may improve
Beyond raw speed, Panther Lake has been positioned to deliver better power efficiency, which should translate into stronger sustained performance and battery life in real-world use. With launch nearing and software optimizations ongoing, expect additional data to refine where Panther Lake lands in gaming, content creation, and everyday workloads.
For now, the outlook is clear: Panther Lake marks a substantial step forward for Intel’s mobile integrated graphics, delivering a notable jump over Lunar Lake and setting a higher baseline for upcoming thin-and-light laptops, even if AMD’s top integrated offerings still set the pace at the high end.
