A new Intel Panther Lake engineering sample has popped up in Geekbench, offering a closer look at what the more mainstream versions of this next-gen mobile lineup could deliver. This time, it’s the Core Ultra 7 366H, a chip that pairs a high core count CPU design with a smaller, 4-core Xe3 integrated GPU (iGPU). Despite the trimmed graphics setup, early results suggest it can still trade blows with older entry-level discrete laptop graphics.
Intel Core Ultra 7 366H specs leaked: 16 cores with a 4+8+4 configuration
The Geekbench listing indicates the Core Ultra 7 366H is a 16-core processor built around a three-tier design: 4 Performance cores, 8 Efficient cores, and 4 LP-E (low-power efficient) cores. The base frequency shows up at 2.0 GHz, while the maximum boost is reported to reach up to 4.8 GHz. Cache details also line up with previous expectations, with 18MB of L3 cache listed.
This configuration reinforces what many expect from Panther Lake in mainstream laptops: lots of threads for productivity and multitasking, backed by a modern platform designed to scale across multiple price tiers.
Xe3 iGPU with 4 cores: Vulkan performance lands around GTX 1050 Ti
What makes this leak particularly interesting is the integrated graphics result. The Core Ultra 7 366H appears to use a 4-core Xe3-based iGPU, and in the Geekbench Vulkan test it scored 22,813 points. That’s roughly in the neighborhood of a GeForce GTX 1050 Ti, which is notable for an iGPU focused on mainstream laptops rather than gaming-first machines.
To put it in context against current AMD integrated options mentioned alongside the leak:
– Versus Radeon 840M (4-core iGPU), the Ultra 7 366H iGPU is about 26% faster in this Vulkan result.
– Versus Radeon 860M (8-core iGPU), it’s nearly 40% slower, which is expected given the sizable difference in iGPU core resources.
In other words, this Ultra 7 configuration doesn’t appear aimed at competing directly with the fastest integrated graphics options in today’s higher-end ultrathin and performance laptop segments. Instead, it looks positioned for everyday laptops that still want respectable GPU capability for light gaming, creative workloads, and hardware-accelerated apps.
How this fits into the wider Panther Lake lineup
Early tests from higher-tier Panther Lake SKUs with 10 or 12 Xe3 GPU cores have indicated much stronger iGPU performance—sometimes approaching entry-level discrete GPU territory around RTX 3050-class results in certain synthetic benchmarks. Those larger-iGPU parts are expected to land in more expensive systems, while 4-core Xe3 variants like the Ultra 7 366H are more likely to show up in mainstream and affordability-focused designs.
A preliminary Panther Lake-H and Panther Lake-U lineup has been circulating, showing a stack that ranges from flagship Core Ultra X9 models down through Ultra 7 and Ultra 5 chips, with varying P-core/E-core/LP-E configurations and iGPU core counts (including 2-core, 4-core, 10-core, and 12-core Xe3 options). Many of the listed chips are shown with a 25W base power target and higher turbo ranges depending on the specific model tier.
What to expect from Core Ultra 7 366H laptops
If these early benchmarks hold up in shipping products, laptops built around the Intel Core Ultra 7 366H could offer:
– Strong CPU-side performance thanks to a 16-core layout designed for modern mobile workloads
– Integrated graphics that can handle esports titles and older AAA games at modest settings, while also accelerating media and creative apps
– A more accessible price point than the higher-end Panther Lake configurations with 10–12 Xe3 GPU cores
As always with early engineering samples, final performance will depend on laptop cooling, power limits, memory configuration, and driver maturity. Still, this leak paints a clearer picture of what Intel’s Panther Lake mainstream iGPU performance could look like: not the fastest in its class, but surprisingly competitive for a smaller 4-core Xe3 design.
