Intel’s new top-end Core Ultra Series 3 mobile chips promise up to 77% faster iGPU gaming performance than Lunar Lake, and come with a whole host of friends

Breaking: Intel Unveils Panther Lake Core Ultra Series 3 Mobile Chips With Bold Gaming Claims

Intel has lifted the curtain on its Panther Lake-based Core Ultra Series 3 mobile processors, pairing performance promises with a fresh approach to integrated graphics. Officials highlighted a claimed jump of up to 77% in integrated graphics performance versus Lunar Lake’s Core Ultra 9 288V, signaling a serious push into gaming-capable notebooks and handhelds without a discrete GPU.

Alongside gaming gains, intel outlined an 18A tile-based packaging strategy and revamped P-cores and E-cores. The family leans into a Battlemage-style integrated GPU evolution, with several SKUs featuring what the company described as a “massive” iGPU designed to deliver ray tracing and higher graphics throughput.

The company also stressed improvements to its GPU driver stack, arguing that better software support could help slim machines deliver more consistent gaming experiences. In short,Intel is aiming to make mobile gaming more viable on devices that emphasize portability and battery life.

Lineup Snapshot: Who’s Who in Panther Lake

The flagship duo kicks off with the Core Ultra X9 388H and Core Ultra 9 386H. The X9 388H pairs a 16‑core engine with an Arc B390 GPU, featuring 12 xe cores and a top P-core speed of 5.1 GHz. It is indeed paired with 12 PCIe lanes, up to 96 GB of LP5/X memory at 9600 MT/s, and a base power of 25 W with turbo power ratings of 65–80 W.

The core Ultra 9 386H shares the same 16-core tally but trims the P-core peak to 4.9 GHz. Its iGPU is a lower‑end Intel Graphics solution with four Xe cores, but it offers more PCIe lanes—20 in total—and memory options including LP5/X 8533 and DDR5 7200. Maximum memory capacity remains 96 GB LP5/X or 128 GB DDR5. Base and turbo power align with the X9 at 25 W and 65–80 W.

Midrange Thrill: Core Ultra X7 And Core Ultra 7

The Panther Lake midrange brings the Core Ultra X7 368H with a 16-core setup and the Arc B390 GPU, delivering 12 Xe cores, 12 PCIe lanes, and a P-core boost up to 5.0 GHz. It maintains a 25 W base and 65–80 W turbo, with 96 GB of LP5/X memory at 9600 MT/s.

The Core Ultra 7 366H keeps the 16-core foundation but uses a lighter iGPU footprint—four Xe cores—while offering more PCIe lanes (20) to support discrete GPUs alongside the CPU. Memory support remains wide, with LP5/X 8533 and DDR5 7200, and a maximum of 128 GB DDR5. Power figures mirror the X7 lineup: 25 W base and 65–80 W turbo.

Another Pair Under the Ultra 7 Banner: 358H, 356H, And 355

the 358H again features Arc B390 and 12 Xe cores, paired with 12 PCIe lanes and a 5.0 GHz P-core cap. Memory is up to 96 GB LP5/X, with 25 W base and 65–80 W turbo power.

the 356H switches to Intel Graphics, retains 16 total cores, but uses four Xe cores and 20 PCIe lanes. It offers LP5/X 8533, DDR5 7200 memory options, and up to 128 GB DDR5. Base remains 25 W with 65–80 W turbo.

Rounding out this branch,the 355 carries 16 total cores with eight P/E balance and four Xe cores,Intel Graphics,and 12 PCIe lanes. Memory options reach LP5/X 7467 or DDR5 6400, up to 128 GB DDR5, with a 25 W base and a turbo cap around 55 W.

Smaller models: Core Ultra 5 Series

The Ultra 5 family introduces the Core Ultra 5 338H and 336H, both with 12 total cores. The 338H ships with a more capable Arc B370 GPU (10 Xe cores) and 12 PCIe lanes,while the 336H relies on Intel Graphics with four Xe cores and 20 PCIe lanes.Memory options for the 338H include LP5/X 8533, with 96 GB maximum, and 25 W base power, turboing to 65–80 W. the 336H follows with 4 Xe cores, the same 25 W base, and a 65–80 W turbo, but supports LP5/X 8533 and DDR5 7200 up to 128 GB.

Why The Architecture Matters

Intel’s Panther Lake emphasizes packaging adaptability through its 18A tile-based approach, enabling a broader spectrum of laptops and handhelds to host these processors.The Arc-based iGPUs—especially the B390 and B370 variants—are designed to lift integrated graphics performance in thin, battery-conscious devices. This could shift how consumers think about gaming on devices without discrete GPUs, especially if XeSS-like upscaling gains traction in future driver updates.

However,Intel has not disclosed every core distribution for every SKU in this initial reveal. the public data centers on total core counts and a mix of arc and Intel Graphics gpus, with varying PCIe lane counts and memory bandwidth across SKUs. Real-world results will depend on final silicon, cooling, and system optimization in forthcoming laptops.

Buying guide: What to Look for in a Core Ultra Series 3 Laptop

1. Check the iGPU EU Count – 128 EU is the sweet spot for 1080p‑144 Hz; 96 EU models are better for productivity.
2. Verify Thunderbolt 5 – Needed for external GPU docks or 8K external displays.
3. Confirm DDR5‑5600+ – Anything below 5200 MT/s bottlenecks the iGPU’s bandwidth.
4. Look for “Intel Evo Platform 2026” badge – Guarantees meeting the 9‑hour battery,Wi‑Fi 7,and instant wake standards.
