Design and Build Quality

The Dell Alienware m15 features a slim profile and angled design lines that give it an edgy, futuristic aesthetic fitting for a gaming laptop. Available color options include Epic Silver, Nebula Red, and Dark Side of the Moon (matte black).

The lid and interior surfaces use a soft touch plastic finish that feels premium and resists fingerprints. While the m15 is slimmer than previous Alienware 15 laptops, it still retains a sturdy, solid build with minimal flex thanks to its magnesium alloy internal frame.

At just 0.83 inches thin and weighing between 4.5-5.5 pounds depending on the configuration, the Dell Alienware M15 delivers impressive portability for a gaming laptop given the powerful components it packs inside.

Portability Compared to Other Models

Compared to the previous Alienware 15 R3, which measured 1 inch thick and 5.8 pounds, the m15 shaves off some thickness and weight for improved mobility. It’s also slimmer than the Alienware m17 R5 (1 inch thick, 6.1 pounds).

The Dell Alienware M15 is still slightly heavier than true ultraportable gaming laptops like the Razer Blade 15 (4.7 pounds) and MSI GS65 Stealth Thin (4.2 pounds). But it’s comparable in weight to other 15-inch gaming laptops like the Asus ROG Strix G15 (5.1 pounds) while retaining a premium, sturdy build.

The Dell Alienware M15 measures 14.3 x 10.8 x 0.83 inches in terms of dimensions. This makes it smaller than the Alienware m17 (15.7 x 11.6 x 1 inch) but slightly larger than the more compact Razer Blade 15 (13.98 x 9.25 x 0.68 inches).

Overall, the Dell Alienware M15 hits a good balance between portable dimensions and sturdy construction that can handle moving around and taking trips. Gamers prioritizing premium build quality in a slim form will appreciate the m15’s design.

Display and Visuals

The Dell Alienware M15 is equipped with a bright and vivid 15.6-inch display available in various resolutions and refresh rates to match different budgets and preferences.

Configuration options include:

  • Full HD (1920 x 1080) at 165Hz
  • Full HD (1920 x 1080) at 360Hz
  • QHD (2560 x 1440) at 240Hz
  • UHD 4K (3840 x 2160) at 60Hz

The panel used is an IPS display which provides wider viewing angles and better color accuracy compared to cheaper TN panels. AMD FreeSync or Nvidia G-Sync technology can be configured for smoother variable refresh rate gaming depending on the graphics card selected.

Out of the box, the Dell Alienware M15 covers close to 100% of the sRGB color gamut which is great for gaming. Higher-end configs with OLED or IPS panels can reach 100% DCI-P3 coverage for more vivid and accurate colors.

Image Quality and Viewing Experience

With brightness levels exceeding 300 nits, the m15’s display is bright enough for comfortable viewing indoors and outdoors. The anti-glare coating also helps minimize reflections.

Colors and contrast are excellent thanks to the IPS panel. Games really come alive with deep blacks and vivid, accurate colors like the neon lights of Cyberpunk 2077. HDR content also looks great with support for Dolby Vision on higher tier configs.

The high 165Hz or 360Hz refresh rate options enable extremely fluid, tear-free gaming by syncing the display’s refresh rate with the GPU’s frame rate. Fast-paced competitive esports titles really shine on the m15 thanks to the buttery smooth visuals from the high refresh rates.

Viewing angles are also wide thanks to the IPS panel so colors don’t shift when viewing the screen off-center, which is useful when gaming with others.

Overall, the Dell Alienware M15 provides an immersive, responsive, and bright display that brings games and media to life. Gamers who want fast refresh rates for competitive gaming or a 4K panel for maximum details will appreciate the display options available.

Performance and Hardware

To deliver an exceptional gaming experience, the Dell Alienware M15 is equipped with high-end specs including Intel Core i7 or i9 processors and Nvidia RTX 30-series graphics.

CPU options consist of:

  • Intel Core i7-12700H (12th Gen)
  • Intel Core i7-11800H (11th Gen)
  • Intel Core i9-11900H (11th Gen)

For graphics, you can configure the m15 with:

These new RTX 30-series GPUs provide incredible performance thanks to new RT cores for ray tracing and AI-powered DLSS for boosted frame rates.

The Dell Alienware M15 also comes equipped with fast DDR5 4800MHz RAM up to 64GB and speedy PCIe NVMe M.2 SSDs up to 4TB. There are two RAM slots and two M.2 slots for storage expansion. Killer Wi-Fi 6E or Wi-Fi 6 connectivity ensures low latency wireless gaming.

Real-World Gaming Performance

With the RTX 3070 Ti graphics and Core i7 processor, the m15 delivers well over 60fps on max settings in demanding AAA games like Red Dead Redemption 2 and Cyberpunk 2077 at 1080p.

Esports titles easily surpass 144fps, enabling high frame rate gaming on 165Hz or 360Hz displays. Performance is on par with or exceeds comparable gaming laptops like the Razer Blade 15 and Asus ROG Strix.

Ray tracing is also handled admirably thanks to the dedicated RT cores in the RTX 30-series GPUs. Frame rates remain very playable in ray traced games like Control and Watch Dogs Legion with DLSS enabled.

Overall, the Dell Alienware M15 provides exceptional 1080p and 1440p gaming performance capable of high frame rates across modern titles. It can even handle 4K gaming at medium to high settings.

Thermal Management

To keep temperatures in check, the Dell Alienware M15 utilizes upgraded Cryo-Tech cooling with turbo fans, pipe heat exchangers, and vapor chamber technology. Performance remains high under sustained loads.

Fans can get loud when gaming, but usually a pair of headphones will drown them out. The optional liquid metal thermal compound on higher-end configs further boosts cooling capacity for enhanced performance.

With its cutting-edge RTX 30-series graphics, latest Intel processors, high-speed memory and NVMe storage, the Alienware m15 delivers incredible gaming power in its thin yet strongly built chassis.

Battery Life of the Dell Alienware m15

For a powerful gaming laptop, the Dell Alienware M15 delivers surprisingly solid battery life thanks to its large battery capacity.

The Dell Alienware M15 is equipped with either a 56Wh or 86Wh battery depending on the configuration. The higher capacity 86Wh battery provides significantly longer run times away from an outlet.

In tests, the Dell Alienware M15 lasted almost 8.5 hours in light web browsing and video streaming with the screen at 50% brightness. This beats out competitors like the Asus ROG Zephyrus, which last under 3 hours in similar tests.

Real world battery life while gaming is closer to 2-3 hours with the 86Wh battery, but still enough for some casual gaming away from the charger. Lowering screen brightness and enabling battery saver modes can further extend unplugged gaming time.

Gaming does drain the battery rapidly, but just for everyday work and productivity away from your desk the m15 has enough juice to get through most of a work or school day without issue.

The beefy 240W power brick can fully charge the m15 in just over 2 hours when you do need to top up. But the long-lasting battery means you don’t always need to carry the charger which is a nice benefit for a gaming laptop of this caliber.

If you want a gaming laptop that can actually be used away from a charger for things like web browsing, video streaming, and office work, the Dell Alienware M15 is a great choice compared to many competitors.

The Dell Alienware M15 comes pre-installed with Windows 11 Home to provide the latest gaming-optimized features from Microsoft. Alienware’s Command Center software is also bundled to enable customization and system monitoring.

Command Center gives you granular control over RGB lighting across multiple zones, allowing complex lighting effects to be set. Performance profiles can be created to customize power delivery, fan speeds, overclocking and more for individual games.

An integrated game library automatically tunes performance profiles when specific game titles are launched. Hardware monitoring lets you track temperatures, clock speeds and other vital system info.

Dolby Atmos spatial audio software is included for immersive sound when using headphones or speakers. The AlienFX SDK allows other apps like Razer Chroma to sync lighting effects with Alienware devices.

McAfee LiveSafe provides security features like antivirus scanning, firewall protection, and data encryption out of the box. This can be extended or swapped for other antivirus software if desired.
