All Specs

While many gaming laptops balance portability and power, MSI’s Raider 18 HX AI throws compromise out the window: This machine goes for power, top to bottom. Starting at $3,999 (as tested), this 18-inch beast tips the scales at nearly eight pounds and delivers top-tier performance with its Intel Core Ultra 9 HX processor and Nvidia GeForce RTX 5080 GPU. You'll find all the latest, most power-packed technology in this laptop, including a breathtaking 4K mini-LED display, Thunderbolt 5, Wi-Fi 7, and PCI Express 5.0 storage. For gamers seeking the pinnacle of performance, the Raider 18 earns our Editors' Choice award for big-screen gaming laptops.

Configurations: Strictly High Performance

At the time of this writing, the Raider 18 HX AI comes in two configurations. Our test unit, if it can be called the "entry level" model, features a Core Ultra 9 285HX processor (24 cores, 5.5GHz turbo), an Nvidia GeForce RTX 5080 GPU with a 175W power ceiling, 64GB of DDR5-6400 RAM, and a 4TB SSD array (two 2TB drives in RAID 0, one of which is PCI Express 5.0). The step-up $5,099 version gets a more powerful GeForce RTX 5090 but cuts the storage to 2TB, with all other specs remaining unchanged. MSI also sells an AMD variant of the Raider dubbed the A18, which includes a Ryzen 9 9955HX3D processor and a GeForce RTX 5080 for $4,099. (A $5,099 RTX 5090 version with that AMD X3D chip is also coming.)

Positioned beneath the Titan line in MSI’s lineup, the Raider family of gaming machines delivers comparable performance in a less elaborate chassis. In turn, it’s more powerful but less portable than MSI's Stealth line.

Design: Bigger and Badder Than Almost Everything

There’s no mistaking the Raider 18’s size: At 1.26 by 15.9 by 12.1 inches (HWD) and 7.94 pounds, it's hefty, even by the standards of 18-inch laptops. By comparison, the Razer Blade 18 (0.86 by 15.7 by 10.8 inches, 6.8 pounds) and the Asus ROG Strix Scar 18 (1.2 by 15.7 by 11.6 inches, 6.61 pounds) are noticeably lighter and more compact. (Not that any 18-inch machine qualifies as truly portable, mind you.)

While the Raider’s sheer size already makes it visually imposing, red-accented air vents along the rear and sides amplify its aggressive look. RGB elements, including a glowing lid logo and a front-facing light bar, further the flair and can be customized for effects and colors via the MSI Center app. The per-key RGB backlit keyboard adds another layer of flash, providing nearly limitless lighting effects through the SteelSeries GG app.

MSI’s build quality is reliable and thorough, prone to only minimal flex. That said, the predominantly plastic chassis' lower half doesn’t impart the premium feeling you might expect from a laptop this expensive, even if the lid is metal.

The arsenal of ports on this laptop includes two Thunderbolt 5 (USB Type-C, 80Gbps), four USB Type-A 3.2 Gen 2 ports, an SD card reader, an HDMI 2.1 video output, a 2.5Gbps Ethernet jack, and a 3.5mm audio jack. The laptop also includes a Killer wireless card supporting Wi-Fi 7 and Bluetooth 5.4.

MSI ships each Raider with a clean install of Windows 11 Home, free of bloatware. MSI’s Center app handles system updates, hardware monitoring, and customization options, including toggling the Windows key, swapping Fn and Windows key functions, enabling an on-screen crosshair, and switching between hybrid and discrete GPU modes via the MUX switch. Additional software includes the Nahimic app for audio tuning and the SteelSeries GG app for keyboard customization. While MSI covers the laptop with an industry-standard one-year warranty, more extended coverage would have been preferable on a laptop this expensive.

Display, Keyboard, and Touchpad: 4K Mini-LED Is Unreal

The Raider’s hallmark feature is undoubtedly its mini-LED panel. It's the closest laptop alternative to a desktop monitor, measuring 18 inches diagonally and with a tall 16:10 aspect ratio. The image quality is exceptional, with brightness beyond compare. (MSI claims a 1,000-nit peak, but our result was slightly south of that.) It also delivers vibrant color and deep contrast. The 120Hz refresh rate isn’t overly fast, but at the panel’s 3,840-by-2,400-pixel resolution, even the GeForce RTX 5080 won’t often push far into triple-digit frame rates (in the most demanding AAA titles, anyway). All told, the Raider delivers a stunning visual experience.

MSI's keyboard bears the brand’s familiar SteelSeries styling but shows little beyond that. Its membrane switches—MSI's mechanical ones remain exclusive to the Titan line—feel flat, with surprisingly shallow travel given the laptop's bulk. Productivity-first users may lament the absence of dedicated Home and End keys, and the arrow keys’ placement within the main layout truncates the size of several keys. On the upside, the Windows key left of the space bar is swappable with the Fn key, or it can be turned off in the MSI Center app. Meanwhile, the expansive touchpad works as expected, providing quiet but tactile physical clicking action.

Tuned for gaming, the Raider’s six-speaker system delivers convincing depth and just enough bass to make explosions noticeable. However, music playback falls short, sounding distant and lacking fullness. The volume is around basic Bluetooth speaker levels—enough to rise above the system’s fan noise, but only just. The fans occasionally ramp up audibly during everyday tasks and get downright loud while gaming, making this laptop less than ideal for quiet environments.

The 1080p webcam over the display provides decent video quality and has a sliding privacy shutter. The fingerprint reader in the palm rest is also welcome, as many gaming laptops leave out biometrics.

Performance Testing: Raiding Through Tasks and Frames

The Raider 18 HX AI will face the Razer Blade 16 (2025) ($4,499 as tested) in our performance tests, which pairs an AMD Ryzen AI processor with a GeForce RTX 5090. We also supplemented our charts with three previous-generation (but still potent) laptops sporting GeForce RTX 40-series silicon, including the Acer Predator Helios 18 ($3,099 as tested), the Asus ROG Strix Scar 18 (2024) ($3,899 as tested), and the 2024 Razer Blade 18 ($4,499 as tested). While these are all powerful machines, the Raider should lead the way, at least in the CPU benchmarks.

Productivity and Content Creation Tests

Our primary overall benchmark, UL's PCMark 10, tests a system in productivity apps ranging from web browsing to word processing and spreadsheet work. Its Full System Drive subtest measures a PC's storage throughput.

Three more tests are CPU-centric or processor-intensive: Maxon's Cinebench 2024 uses that company's Cinema 4D engine to render a complex scene; Primate Labs' Geekbench 6.3 Pro simulates popular apps ranging from PDF rendering and speech recognition to machine learning; and we see how long it takes the video transcoder HandBrake 1.8 to convert a 12-minute clip from 4K to 1080p resolution.

Finally, workstation maker Puget Systems' PugetBench for Creators rates a PC's image editing prowess with various automated operations in Adobe Photoshop 25.

The Raider set an incredibly high standard with nearly 9,000 points in PCMark, the highest score we’ve seen from a laptop. Curiously, however, it scored only so-so in the storage test, which may be down to an incompatibility between the test and the rarely seen PCIe 5.0 drive in this laptop. Its Core Ultra 9 285HX CPU delivered commanding performance across all processor benchmarks, considerably outdistancing the competition in several tests.

In fact, this laptop performs at the level of many higher-end desktops. That, combined with this laptop's AI processing chops for tasks like enhanced content creation, puts the Raider in pole position among desktop replacement machines.

Gaming and Graphics Tests

We challenge all systems’ graphics with a quartet of animations or gaming simulations from UL's 3DMark test suite. Wild Life (1440p) and Wild Life Extreme (4K) use the Vulkan graphics API to measure GPU speeds. Steel Nomad's regular and Light subtests focus on APIs more commonly used for game development, like Metal and DirectX 12, to assess gaming geometry and particle effects. We turn to Solar Bay to measure ray tracing performance in a synthetic environment. This benchmark works with native APIs, subjecting 3D scenes to increasingly intense ray-traced workloads at 1440p.

Our real-world gaming testing comes from the in-game benchmarks of Call of Duty: Modern Warfare 3, Cyberpunk 2077, and F1 2024. These three games—all benchmarked at the system’s full HD (1080p or 1200p native) resolution—represent competitive shooter, open-world, and simulation games, respectively. If the screen is capable of a higher resolution, we rerun the tests at the QHD equivalent of 1440p or 1600p. Each game runs at two sets of graphics settings per resolution for up to four runs total on each game.

We run the Call of Duty benchmark at the Minimum graphics preset—aimed at maximizing frame rates to test display refresh rates—and again at the Extreme preset. Our Cyberpunk 2077 test settings aim to push PCs fully, so we run it on the Ultra graphics preset and again at the all-out Ray Tracing Overdrive preset without DLSS or FSR. Finally, F1 2024 represents our DLSS effectiveness (or FSR on AMD systems) test, demonstrating a GPU’s capacity for frame-boosting upscaling technologies.

In 3DMark, the Raider impressively held its own against the Blade 16 on average despite using a GeForce RTX 5080 versus an RTX 5090, though all the laptops performed similarly in these tests. The Raider proved particularly formidable in the real-world gaming benchmarks, again just half a step behind the Blade 16 in Cyberpunk 2077 at most settings. (The only test we don’t have results for is Call of Duty, which was due to an issue with the game itself and not the Raider’s capabilities.) The Raider also showed marked improvement over the rest of the field, particularly at 1080p and 1200p resolutions, where the CPU plays a more significant factor. Look at it at 1080p and Ultra settings in Cyberpunk 2077.

We also anecdotally ran the real-world games at the Raider’s native 4K resolution, where it achieved 41fps in Cyberpunk 2077 (Ultra, no ray tracing) and 154fps in F1 24 (Ultra High, DLSS on). In short, this Raider produces dream-level performance for any kind of gaming or content creation.

Battery Life and Display Tests

We test each laptop's battery life by playing a locally stored 720p video file (the open-source Blender movie Tears of Steel) with display brightness at 50% and audio volume at 100%. We make sure the battery is fully charged before the test, with Wi-Fi and keyboard backlighting turned off.

To gauge display performance, we use a Datacolor SpyderX Elite monitor calibration sensor and its Windows software to measure a laptop screen's color saturation—what percentage of the sRGB, Adobe RGB, and DCI-P3 color gamuts or palettes the display can show—and its 50% and peak brightness in nits (candelas per square meter).

Although the Raider’s battery life is middle-of-the-pack among this group, lasting nearly six hours is quite impressive for a hulking gaming laptop, particularly considering its high screen brightness at the 50% setting we use for testing.

The Raider’s mini-LED display distinguishes itself with near-total gamut coverage and exceptional brightness. While the other contenders all feature decent high-end screens, the Raider operates in a different league entirely.
