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.
Core Ultra 9 275HX Benchmarks and Real-World Performance
Benchmark results vary by laptop, because power limits and cooling decide how long the chip holds its boost. The figures below come from published aggregates and independent reviews, not from our own runs.
| Benchmark | Reported result |
|---|---|
| PassMark multithread | About 55,700 |
| PassMark single-thread | About 4,700 |
| Cinebench 2024 multi-core | About 1,700 to 2,150 depending on the laptop |
| Geekbench 6 single / multi | About 3,030 / 18,800 |
| Versus Core i9-14900HX at launch | About 34 percent faster in early benchmarks |
| Versus Core Ultra 7 265HX | About 14 percent faster in PassMark |
Gaming performance: what to expect
For gaming, the Core Ultra 9 275HX rarely holds back the GPU. At 1440p and 4K the graphics card sets the frame rate, so a 275HX laptop with an RTX 5070 or RTX 5070 Ti delivers high frame rates with high or ultra settings. At 1080p in CPU-heavy esports and simulation titles, the Ryzen 9 9955HX3D from AMD pulls ahead thanks to its large 3D V-Cache. Independent testing reports about a 16 percent average gap at 1080p across a 29-game suite.
Creator and workstation performance
With 24 cores, the 275HX is strong in video export, 3D rendering, code compilation and heavy multitasking. It performs near the top of mobile CPUs, close to the 285HX. If you edit video on a laptop and also game, a 275HX machine is a strong all-in-one choice.
Power, thermals and noise
The 275HX is a 55 W base-power chip that can boost to 160 W in short bursts. Real sustained power depends on the laptop. Thin designs cap power at a lower level and give up some performance, while 16 to 18-inch gaming laptops with vapor chambers or liquid metal can hold higher power. Expect fan noise under load, and look for models with a Performance or Turbo mode you can switch on for long sessions.
Battery life
Arrow Lake-HX is built for performance, not endurance. Gaming laptops with the 275HX last a few hours of light use and far less in games, so plan to plug in. Efficiency chips such as the Core Ultra 9 288V or Qualcomm and AMD low-power parts last longer but give up core count.
Integrated graphics and NPU
The chip includes integrated Intel graphics, which handle desktop work and let the laptop switch off the discrete GPU to save power. The NPU delivers up to 13 TOPS, which is well below the 40 TOPS Microsoft asks for Copilot+ PCs, so do not buy a 275HX laptop for on-device AI features.

Core Ultra 9 275HX Laptop Buying Guide
Pair the CPU with the right GPU
A 275HX laptop is only as good as its graphics card and cooling. Treat these as tiers: RTX 5060 for 1080p high settings, RTX 5070 for 1440p, RTX 5070 Ti for 1440p high refresh and light 4K, and RTX 5080 or RTX 5090 for high-end 4K and heavy creator work. Do not pay for a 275HX with a low-end GPU unless you need the CPU for work.
Look at cooling and power limits
Two laptops with the same 275HX can perform very differently. Look for the maker’s total graphics power rating for the GPU, a vapor chamber or large heat pipes, and a performance mode. A slim chassis often holds back the CPU to keep temperatures down. 16 and 18-inch models give the chip more room.
Memory and storage
Choose at least 32GB of DDR5 for gaming and creator work, and a 1TB SSD or larger. Some listings carry only 16GB of RAM, and the lower-capacity versions of the same model can cost noticeably less. If a laptop has two SODIMM slots, you can upgrade later.
Display matters as much as the CPU
A 16-inch 2560×1600 panel at 240 Hz is the common match for the 275HX. OLED panels give better contrast and color, while mini-LED and IPS options give higher brightness. For competitive play, prefer 240 Hz or higher with good response times.
Check ports and connectivity
Look for Wi-Fi 7, Thunderbolt or USB4 ports, HDMI 2.1, and an Ethernet port if you game on wired internet. Port options depend on the laptop maker, not the CPU.
