Dell Alienware 18" AA18250 Liquid Teal 2025

This is one of the fastest laptops we've ever seen, with an RTX 5090 and Core Ultra 9 that land in the top percentiles for gaming and AI performance. The 18-inch 300Hz display is gorgeous, and you get a ton of RAM and storage. The catch is that it weighs over 9.5 pounds and has some of the worst portability and reliability scores in its class, so it's a desktop replacement through and through.

This laptop's performance is the main event, and the numbers are staggering. The combination of the 24-core Intel Ultra 9 275HX and the RTX 5090 makes it a top-tier machine for gaming, AI work, and content creation. In our gaming benchmarks, it scored an 85.3 out of 100, which is leading the pack. The AI and LLM score is even more impressive at 87.1, making this a genuine portable workstation for machine learning tasks. You're looking at frame rates that can fully leverage that 300Hz display in competitive shooters, and the 24GB of VRAM means you can crank texture settings and ray tracing without hitting a wall.

The 64GB of DDR5 RAM is a massive help for heavy multitasking and creative workloads like 4K video editing, landing in the 96th percentile. The 2TB SSD is also well above average for storage speed and capacity. The real-world takeaway is simple: this machine chews through anything you throw at it. Compile times, render times, and load times are all dramatically shorter than what you'd see on a typical gaming laptop. It's one of the fastest laptops we've ever tested, plain and simple.

Stacked against the competition, the Alienware AA18250 is the brute-force champion. The ASUS ROG Zephyrus G14 is a marvel of portability and efficiency, but its mobile-focused RTX 5080 can't touch the raw power of the 5090 in this Alienware. The Lenovo Legion Pro 7i Gen 10 is a closer fight, offering a similar desktop-replacement vibe, but the Alienware's CPU and RAM configuration give it a clear edge for creator and AI tasks. The Apple MacBook Pro M4 Max is a different beast entirely, with vastly superior battery life and build quality, but it can't compete in raw gaming frame rates or with the 24GB of VRAM for certain professional 3D and AI applications. You're choosing between a surgical instrument and a sledgehammer, and this Alienware is definitely the sledgehammer.

Pricing on this Alienware is all over the map, with a spread of over $105,000 between the lowest and highest vendor listings we found. That's not a typo. The realistic street price seems to start around $3,980, which, for an RTX 5090 laptop with 64GB of RAM and a 2TB SSD, is actually a strong price-to-performance ratio at the very top end. You're getting a no-compromises desktop replacement for less than some competing workstations. Just be very careful where you buy it, because some third-party sellers are clearly hoping you won't shop around.

The Alienware AA18250 is an absolute monster. We're talking an Intel Core Ultra 9 275HX and a full-powered RTX 5090 with 24GB of VRAM, which puts it in the 97th and 92nd percentiles for CPU and GPU performance in our database, respectively. That's not just fast, that's one of the best on the market right now. You also get a generous 64GB of DDR5 and a 2TB NVMe SSD, so storage and multitasking are covered in a big way. The 18-inch 300Hz display is a standout too, hitting 500 nits of brightness with full DCI-P3 color coverage, making games look incredibly smooth and vibrant.

But all that power comes with some serious baggage, literally. At 4.34kg, this thing is a desktop replacement in the truest sense, landing dead last in our compactness rankings. Portability is not its strong suit. Reliability scores are also a weak spot, sitting in the 32nd percentile, which is a bit of a red flag for a machine this expensive. You're buying it for raw, unadulterated performance, and on that front, it delivers, but you'll want to keep it parked on a desk.

Anyone who needs to actually carry their laptop around should look elsewhere. The 4.34kg weight and massive 18-inch chassis make this a terrible travel companion, and the unknown battery life is almost certainly a disaster away from an outlet. If portability matters at all, a machine like the ASUS ROG Zephyrus G14 will serve you much better. You should also skip this if long-term reliability is a top concern, as its below-average score in our database suggests it might not age as gracefully as some competitors.

The Dell Alienware AA18250 is an uncompromising performance machine for people who never plan to unplug it. It earns its place as one of the fastest laptops in our database, delivering a desktop-like experience for gaming, AI, and creative work. The port selection is fantastic, the display is a joy, and the sheer speed is intoxicating. The major trade-offs are its back-breaking weight and some worrying reliability data. If you need the absolute most frames per second or the fastest AI model training you can get in a laptop form factor, and you have a dedicated spot for it on your desk, this is a top contender. Just don't expect to take it anywhere.
