The Intel Core Ultra 9 275HX has quickly become the processor of choice for high-end gaming laptops, anchoring flagship machines from ASUS, Acer, and MSI. With 24 cores and boost clocks north of 5GHz, it’s built to feed the fastest mobile GPUs without becoming a bottleneck, exactly what you want behind an RTX 5070 or 5070 Ti.
Because you buy this chip inside a laptop rather than on its own, we looked at how the 275HX performs in the systems that carry it and how it compares to Intel’s desktop and other mobile parts. Here’s what the 275HX delivers and which laptops make the best use of it.

Design & Build
The 275HX shows up in serious gaming hardware. The ASUS ROG Strix G16 pairs it with a 2.5K 240Hz ROG Nebula display and RTX 5060 graphics in a refined chassis, while the Acer Predator Helios Neo 18 goes big with an 18-inch WQXGA 240Hz G-SYNC panel, RTX 5070 Ti, and robust cooling for sustained performance. MSI’s Crosshair 18 HX AI offers a similar large-format, high-refresh approach with RTX 5070 graphics. These are substantial, well-cooled laptops, the 275HX’s power demands reward big chassis with strong thermal headroom, and the 16 to 18-inch high-refresh displays are matched to the horsepower inside.
Performance
The Core Ultra 9 275HX is a 24-core powerhouse, with 8 performance cores and 16 efficiency cores boosting up to 5.4GHz, and it excels at both gaming and heavy multithreaded work like rendering and streaming. In laptops like the Predator Helios Neo 18 and MSI Crosshair 18, it keeps high-end GPUs fed at high frame rates and handles demanding creative workloads with ease. Paired with 32GB of DDR5 and fast Gen 4 SSDs, these systems are genuine desktop-replacement machines. For context, Intel’s desktop Core Ultra 9 285K and 270K push even higher clocks in a tower, but the 275HX brings that class of multithreaded muscle to a portable, if large, form factor.
Pros & Cons
- 24 cores for elite gaming and multithreaded performance
- High boost clocks up to 5.4GHz keep top GPUs fed
- Pairs with RTX 5070/5070 Ti in premium laptops
- Excellent for creators who render, stream, and game
- High power draw favors large, well-cooled chassis
- Reduced battery life compared with efficiency-focused chips
- Premium pricing on the laptops that carry it
Alternatives to Consider
If you want strong gaming with better portability and battery life, an efficiency-tuned chip like a Core Ultra 9 288V or a Ryzen HX part in a thinner laptop may suit you better. Gamers on a tighter budget can pair a lower-tier CPU with the same GPU and lose little in real-world frames. And desktop builders chasing maximum multithreaded output should look at the Core Ultra 9 285K instead. Match the 275HX to your need for portable, no-compromise gaming and creation power.
Frequently Asked Questions
Is the Intel Core Ultra 9 275HX good for gaming?
Yes, it’s one of the best mobile gaming CPUs available, with enough cores and clock speed to keep high-end GPUs like the RTX 5070 Ti running at full tilt without bottlenecking.
What laptops use the 275HX?
Flagship gaming laptops such as the ASUS ROG Strix G16, Acer Predator Helios Neo 18, and MSI Crosshair 18 HX AI, typically paired with RTX 50-series GPUs, 32GB of DDR5, and high-refresh displays.
How many cores does the 275HX have?
It features 24 cores, 8 performance cores plus 16 efficiency cores, with boost clocks up to 5.4GHz, making it excellent for both gaming and multithreaded creative work.
Does a 275HX laptop have good battery life?
