As long as laptop buyers have been forced to make compromises, the one thing no one has questioned is: if you want to play games, you buy a heavier machine. The integrated graphics were fine for everything else—browsing, video calling, the occasional old title—but the moment you asked one to run a proper AAA game at playable framerates, it just wasn’t up to the task. It was just the deal and the industry moved on accordingly.
The Intel Core Ultra Series, codenamed Panther Lake, is the first serious attempt to change that.
What is Intel Core Ultra Series 3?
Announced at CES 2026, the Core Ultra Series 3 are Intel’s latest generation of mobile processors and the first to be built on their in-house 18A process node – a meaningful manufacturing milestone that delivers real gains in both performance and energy efficiency. The range runs from the Core Ultra 5 to the flagship Core Ultra X9 388H, designed to cover everything from everyday ultrabooks to high-performance business machines.
Under the hood, the architecture uses Intel’s hybrid core approach: next-generation Performance cores (P-cores) for fast, responsive tasks; Efficient cores for multitasking and parallelism (E-cores); and Low Power Efficient cores (LPE) that handle lighter workloads without unnecessarily tapping the battery. Top-end chips reach just 16 cores, and the new NPU 5 architecture delivers up to 50 TOPS of AI performance, making every chip in the lineup fully Copilot+ from day one.
But while the CPU and NPU upgrades are impressive, they’re not why people are paying attention to the Intel Core Ultra Series 3. GPU is like that.
Arc B390: The iGPU That’s Actually Gaming
The Core Ultra X7 and X9 variants are equipped with Intel Arc B390 – an integrated GPU built on the new Xe3 architecture with up to 12 Xe3 cores. The previous generation Arc 140V in Moon Lake had 8 Xe cores, so that’s a 50% increase in core count out of the gate. Intel claims 77% better gaming performance than its predecessor thanks to architectural improvements
Competitive comparisons are where it gets really interesting. At a continuous 45W full CPU package TDP, the Arc B390 is about 10% faster than NVIDIA’s RTX 4050 Laptop when the GPU only consumes 60W. The RTX 4050 isn’t some relic – it’s the current discrete GPU shipment in dedicated gaming laptops right now. In the same power envelope, the gap against AMD’s Radeon 890M is even wider: the B390 is about 80% ahead in native 1080p gaming.
We tested it ourselves on the Asus ExpertBook Ultra, one of the first notebooks equipped with a Core Ultra X7 358H and a full 12-core Arc B390. In 3D Mark, it scored 6,713 in Time Spy and 12,838 in Fire Strike – beating similarly specced machines across the platform. In actual gaming, testing it at 1080p medium settings without upscaling, it delivered 63fps in Horizon Zero Dawn, 59fps in Shadow of the Tomb Raider, and 37fps in Black Myth: Wukong with XeSS enabled. Doing all this, the ExpertBook Ultra weighs less than 1 kg and is 10.9 mm thin. This combination simply did not exist before.
Then there’s XeSS 3, which takes things even further. Intel’s AI-powered enhancement combines Super Resolution with Multi-Frame Generation—a technology that inserts up to four AI-generated frames between each captured frame. The Arc B390 is currently the only integrated GPU in the world that supports Multi-Frame Generation. Turn it on in Assassin’s Creed Shadows and frame rates jump to 100fps. Cyberpunk even produces similar results. There are some caveats—frame capture works best at higher refresh rates and can show small artifacts in fast action sequences—but the ceiling it creates for a chip without a discrete GPU is something the industry hasn’t seen before.
It should be noted that the full Arc B390 with 12 Xe3 cores is unique to the X-series chips – Core Ultra X7 and X9. The Core Ultra 5 338H gets the Arc B370 with 10 Xe3 cores, which is still a powerful GPU for its class. Other Core Ultra 5 and standard Core Ultra 7 variants come with Intel Graphics, a more traditional integrated solution. If gaming is a priority, the X Series designation is what you’re looking for in the spec sheet.
The Bigger Picture
Intel Core Ultra Series 3 isn’t just a generational GPU bump. It’s the first time that integrated graphics are truly competitive with entry-level discrete GPUs in real-world gaming workloads — and the gap closes even further when you base XeSS 3’s frame generation.
In fact, the Intel Core Ultra X 3 series made the concept of a lightweight gaming laptop with multi-day battery life possible. Now you can play AAA games for hours on the go or work and read for days on the same device without needing to charge your laptop.
Whether that’s enough to make you reconsider skipping a discrete GPU on your next laptop purchase depends on what you play and how demanding you are about the settings, but it’s worth the conversation now. This was not the case a year ago.
