Alienware Area 51 18 laptop review: Unbelievable performance - for a price

As a fervent PC gamer growing up in the 2000s, Alienware embodied the zenith of gamer style, performance, and price tag, and in 2026, the Alienware Area 51 18 still carries the flag as an unbelievably cool-looking laptop with unbelievable performance at an unbelievable price.

The machine that Dell sent us was 'money-is-no-object' specification, as I like to refer to it, featuring an Nvidia RTX 5090 24GB mobile GPU running at the full 175 watts, 24-core Intel Core Ultra 9 290HX Plus, 64GB DDR5 6400MT/s RAM, 2TB NVMe SSD, 18" 2560x1600 300Hz display and a CherryMX low-profile mechanical keyboard with per-key AlenFX RGB lighting.

The laptop itself is a beautiful piece of kit to behold, with an exquisite, organic, extraterrestrial design language, a welcome departure from the harsh industrial looks of yore, that elevates it above much of the competition.

The rear vents in particular are a delight, reminiscent of manta rays, or Combine Dropships from Half-Life.

They aren’t just for show either, as they afford the Alienware Area 51 18 some serious cooling chops by feeding cool air to the massive fans which sap heat from the gigantic vapour chamber, ensuring the laptop remains fairly quiet even when under load, save for the Overdrive mode.

A window in the base of the laptop allows you to glimpse at the magic inside, but you can only see said fans and some lights, though it’s very neat to see all the same.

The Cherry MX mechanical keyboard is great for gaming, but typing all day can be a bit tiring on the fingers, though the Alienware Area 51 18 isn’t exactly positioning itself as a svelte office word processing machine.

Gaming is an absolute breeze, to the point that it doesn’t even feel that necessary to share benchmarks. If you have a game, you are going to be able to run it at max settings, especially when using the laptop's own display. It is an Nvidia RTX 5090 mobile GPU running at the full 175 watts, after all.

When frame rates are a little shaky, you can employ multi-frame generation to smooth it out, or simply to make better use of the 300Hz display.

The only titles that will remotely make the Alienware Area 51 18 sweat are the likes of Cyberpunk 2077 with path-tracing at 4K, but a few smart settings choices will also save the day here.

I was hovering around 30 FPS at Overdrive settings at 4K with DLSS 4 Transformer Model set to quality, but dropping down to balanced, and trimming some settings with diminishing returns, helped me get into territory I’d be comfortable using frame generation in, without too much of a latency penalty.

Another game in my regular rotation is Arma Reforger, which curiously has no upscaling options, but even at native resolution and despite the game being so CPU-intensive, I was well north of 60FPS, often in the 80-90s, thanks in no small part to the RTX 5090 and 24-core Intel Core Ultra 9 290HX Plus.

For professional workloads such as video editing, the Alienware Area 51 18 hardly breaks a sweat. With 24GB of video memory and 64GB of system memory, Adobe Premiere hummed along nicely, and I was able to edit long-format multi-cam interviews with RAW 4096 x 2160 10-bit footage with no issues at all. Render times were delightfully quick, something extremely important when working under an editorial process that requires tight deadlines.

A fast SD card reader slot means ingesting footage from cameras is breezy, and there are oodles of inputs and outputs on the back, making it a very neat and tidy setup, even if you have lots of peripherals plugged in.

Be it gaming or video editing, it all looks surprisingly good on the 18" display, given that it is only an LED-backlit IPS LCD panel. It is decently colour accurate, but if you are spending this much money on a laptop, you likely have the cash to spare on a good external monitor too.

Sadly, there are no miniLED or 4K options, which can be found on competing laptops, but the display is still decently sharp and bright, and the G-Sync 300Hz display with Advanced Optimus support makes it great for faster-paced competitive games.

It is also, of course, a massive beast of a machine, and weighs over a combined 5KG when including the power supply, making the prospect of chucking it in your bag laughable.

The elephant in the room (other than the gargantuan laptop) is that the Alienware Area 51 18 laptop in its top spec configuration is unbelievably expensive. On the Dell website, the laptop comes to £6,048.98, when specifications are maxed out (save for storage options that further swell the price), making it attainable only by gamers who have very deep pockets. This has been exacerbated by the ongoing memory pricing crisis, which will likely push that price higher.

The GPU alone has 24GB of GDDR7 VRAM, which, whilst excellent for path-traced games and professional workloads, is a financial black hole for OEMs such as Dell, as memory manufacturers push their prices ever higher.

There are more financially attainable specs if you are dead-set on the form factor and design, and there is also the smaller 16 variant that will be more readily transportable.

But, if you're in the market for a computer that you might want to move from time to time that spares no expense in the pursuit of performance, then the Alienware Area 51 18 could be the laptop for you – if you can afford it, that is.
