Intel has officially pulled the curtain back on its next wave of laptop-focused processors: Core Ultra Series 3, better known by the codename Panther Lake. It’s a major milestone for the company because these chips are the first official product built on Intel’s 18A manufacturing technology, and they’re designed to blend high performance, strong efficiency, and bigger AI capabilities in a modern multi-tile package.
Intel previously confirmed that Panther Lake will be formally launched at CES 2026, but the company is already sharing early performance claims and key platform details. The message is clear: Panther Lake is meant to be a true “do-it-all” mobile platform, scaling from thin-and-light systems to higher-performance laptops—without focusing only on “AI PC” marketing.
Performance and graphics claims: what Intel is promising
Intel highlighted Cinebench 2024 multi-threaded results as an early look at CPU performance. According to the company, the flagship Core Ultra X9 388H delivers up to a 60% multi-thread uplift at the same power level, and it’s positioned ahead of AMD’s Ryzen AI 9 HX 370 in that specific comparison.
On the graphics side, Intel is leaning heavily into its new Xe3-based integrated GPU. The company claims the Arc B390 iGPU can deliver up to a 73% performance gain versus AMD’s Radeon 890M iGPU across a broad set of games at 1080p. Intel also notes this iGPU is the first to offer Multi-Frame Generation support, alongside additional modern graphics features.
Three Panther Lake die options, built for flexibility
One of the most interesting parts of Panther Lake is how Intel is segmenting it. Instead of a one-size-fits-all approach, Intel is preparing three primary die configurations that will feed the Core Ultra Series 3 (Core Ultra 300) product stack.
This structure gives Intel more room to tailor performance, efficiency, and graphics capability than some prior families. The 8-core-style approach is positioned to succeed the ultra-efficient segment, while the 16-core designs are aimed at higher-performance laptop categories.
Panther Lake 8C die: efficient core layout, modern connectivity
The entry Panther Lake 8C arrangement uses 4 performance cores plus 4 low-power efficiency cores. Intel also integrates major “xPU” elements into the compute tile, including IPU 7.5, NPU5, plus updated media and display engines.
Memory support on this die goes up to LPDDR5x-6800 and DDR5-6400, and Intel includes 8MB of memory-side cache. Cache is listed as 12MB of L2 for the P-cores, plus 4MB of L2 for a single Darkmont cluster. Intel notes the compute tile is built on the 18A node.
Graphics on this version tops out at 4 Xe3 cores with 4 ray tracing units, and the graphics tile is produced using Intel 3 process technology.
For I/O and wireless, the platform controller tile is manufactured on an N6 node and supports up to 12 PCIe lanes (8 Gen4 + 4 Gen5), plus a mix of USB connectivity, along with Intel Wi‑Fi 7 (R2) and Intel Bluetooth Core 6.0.
Panther Lake 16C die: more CPU cores and higher memory ceilings
Moving to the 16-core compute configuration, Intel adds 8 E-cores, bringing the layout to 4 P-cores, 8 E-cores, and 4 LP-E cores. Intel lists 12MB of L2 for the P-cores and 12MB of L2 for the E-cores across three clusters.
Memory support climbs to LPDDR5x-8533 and DDR5-7200. The platform controller tile also expands to up to 20 PCIe lanes, including 12 Gen5 lanes on this SKU.
Graphics remains at up to 4 Xe3 cores on the graphics tile, again using Intel 3 process technology.
Panther Lake 16C with 12 Xe cores: the big iGPU option
At the top, Intel pairs the same 16-core compute tile with a much larger integrated graphics tile. Memory support jumps to LPDDR5x-9600, a key upgrade that Intel ties directly to feeding the higher-performance iGPU with more bandwidth (150+ GB/s is referenced).
This variant upgrades the iGPU to 12 Xe3 cores and 12 ray tracing units. Intel states the GPU tile is fabricated on an N3E process, while the platform controller tile returns to the 12 PCIe lane configuration used on the 8C variant.
Core Ultra Series 3 (Core Ultra 300) lineup: models and core counts
Intel also shared official model names and a basic spec snapshot for the initial Core Ultra Series 3 laptop stack, ranging from Core Ultra 3 up through Core Ultra X9. Across the list, the higher-end “H” models generally feature 4 P-cores, 8 E-cores, and 4 LP-E cores, while some lower-tier options use 4 P-cores and 0 E-cores with 4 LP-E cores. Boost clocks range up to about 5.1 GHz depending on SKU, with base/MTP power ranges spanning roughly 25W up to 80W depending on the specific model.
Why Panther Lake matters for 2026 laptops
Panther Lake is shaping up to be a pivotal platform for the next generation of laptops: Intel’s first 18A product, new CPU cores, a significantly updated Xe3 iGPU approach (including higher-end 12 Xe configurations), and an expanded focus on on-device AI acceleration through updated NPU/IPU blocks.
If Intel’s performance-per-watt and integrated graphics claims hold up in real-world testing, Core Ultra Series 3 could be one of the most important laptop CPU launches heading into 2026—especially for buyers who want strong gaming-at-1080p potential from integrated graphics, faster memory support, modern connectivity, and improved efficiency without jumping to a bulky discrete-GPU system.
