Alienware x16 R2 laptop review: A step sideways from the x16 R1

The ultra-thin Alienware x16 series launched late last year with the debut of the Alienware x16 R1. For 2024, the series has been refreshed with the x16 R2. The newer model swaps out the older Raptor Lake-H processor options with AI-ready Meteor Lake-H options while everything else remains essentially the same as the original x16 R1 design. We therefore recommend checking out our review on the x16 R1 as most of our existing comments still apply for the visually identical x16 R2. Any notable differences will be noted in this review.
Our unit in review is a higher-end configuration with the Core Ultra 9 185H CPU, 175 W GeForce RTX 4080 GPU, 1600p 240 Hz display, and ultra-low profile CherryMX mechanical keys for approximately $3200 USD. Other SKUs include regular membrane-based keys and the Core Ultra 7 155H with GeForce RTX 4060, 4070, or 4090 graphics and 1200p 480 Hz IPS display instead.
Alternatives to the Alienware x16 R2 include other high-end 16-inch gaming laptops like the Razer Blade 16, Asus ROG Strix Scar 16, Lenovo Legion Pro 7 16, or MSI Vector 16 HX.

Dell has upgraded the WLAN module for this year's refresh to support Wi-Fi 7.
Webcam

Display — No More 165 Hz Option
Dell has swapped out the BOE NE16NZ4 panel on last year's x16 R1 for the BOE B160QAN on this year's x16 R2. However, the two panels are otherwise almost identical in terms of color reproduction, response times, brightness levels, and contrast for an essentially identical viewing experience.
The native refresh rate can be set to 240 Hz or 60 Hz with no variable options. G-Sync is supported only when set to dGPU mode and not Optimus mode.
Users can configure between two displays as shown below whereas the x16 R1 had three:
- 2560 x 1600, 240 Hz, 100% DCI-P3, G-Sync, Advanced Optimus
- 1920 x 1200, 480 Hz, 100% DCI-P3, G-Sync, Advanced Optimus

Performance — Core Ultra 9 185H vs. Core i9-13900HK
Testing Conditions
We set Alienware Command Center to Overdrive mode and the graphics to dGPU mode for the best possible benchmark results. Owners are encouraged to become familiar with Command Center as it is the hub for adjusting RGB lighting effects and performance profiles.
Nvidia Control Panel offers no "iGPU only" mode as shown by the screenshot above.
Processor
The Core Ultra 9 185H is approximately 5 to 10 percent and 15 to 20 percent slower than the Core i9-13900HK in last year's x16 R1 when it comes to multi-threaded and single-threaded applications, respectively. Interestingly, downgrading to the Core Ultra 7 155H configuration is not expected to impact performance by any significant margins on our time with the Alienware m16 R2 as shown by the comparison chart below.
Raptor Lake-HX options such as the Core i9-14900HX are not available on the Alienware x16 series likely due to thermal limitations since these processors require more power than the Meteor Lake-H series. Such options would have offered significantly faster performance than both the Core i9-13900HK or Core Ultra 9 185H.

Stress Test
Core temperatures between the CPU and GPU are just as warm as what we recorded on the x16 R1. The CPU in particular still stabilizes at almost 100 C (!) when running Prime95 while the GPU stabilizes in the mid 80 C range when running Witcher 3. Interestingly, GPU clock rate is down across the board when compared to the x16 R1. The GPU would range between 2100 to 2325 MHz depending on the power profile compared to 2460 MHz on the original x16 R1. Board power draw would also be lower on the newer x16 R2 model (150 W vs. 165 W). These findings correlate with the generally slower graphics performance in the GPU Performance section below.

GPU Performance
The 175 W mobile GeForce RTX 4080 GPU remains the same albeit with 3DMark scores that are about 5 percent slower than what we recorded on the x16 R1. Upgrading to the RTX 4090 configuration is expected to improve performance by just 5 to 15 percent while downgrading to the RTX 4070 or 4060 will reduce performance by as much as 30 percent and 45 percent, respectively.
Power Profile | Graphics Score | Physics Score | Combined Score |
Overdrive Mode | 42558 | 29029 | 11691 |

Battery Power | 21754 (-49%) | 25880 (-11%) | 9863 (-16%) |
Running the system on Performance mode instead of Overdrive mode will impact overall performance slightly as shown by our Fire Strike results table above. Interestingly, the difference between Performance and Balanced modes is comparatively much smaller.

Gaming Performance
Disappointingly, performance in games would be consistently slower than what we recorded on the x16 R1 by about 5 to 15 percent. The wider deltas would occur at lower resolutions while the smaller deltas would occur at higher resolutions which is consistent with the slower raw CPU performance results when compared to the Core i9-14900HK noted above.

Emissions
System Noise
The fans in the x16 R2 are able to remain quieter for longer periods before needing to ramp up in speed and noise. Otherwise, the noise ceiling is similar to what we recorded on the x16 R1 at about 50 dB(A) and 54 dB(A) when gaming on Performance mode and Overdrive mode, respectively. Note that fan noise when gaming on Balanced mode would be exactly the same as Performance mode which aligns with our 3DMark results above.

Energy Management
Power Consumption
Overall consumption is generally lower than what we recorded on the x16 R1 by about 10 to 15 percent when running demanding loads like games or Prime95 stress. However, this deficit accompanies the slower CPU and GPU results noted above. Performance-per-watt is therefore about the same year-over-year despite the CPU change.
We encountered a bug when on Standby mode. If set to Optimus, Standby mode would operate normally with a low <1 watt power draw. If set to dGPU mode and Overdrive, however, Standby mode would demand as much as 39 W resulting in an unnecessarily warm laptop and high battery draw.

Battery Life
Runtimes are a bit longer this time around likely due to the overall lower power consumption noted above. We're able to record a WLAN runtime of over 40 minutes longer than on the x16 R1, but most other gaming laptops are still able to last much longer including Dell's own Alienware m16 R2.

Pros
Cons
Verdict — Alienware x16 R1 Is Faster For Pure Gaming
The big advantage that the Alienware x16 R2 has over the x16 R1 is its integrated NPU for accelerating Windows AI tasks. Such features are expected to become commonplace in the next year or so via Microsoft Co-Pilot and other upcoming Ai-driven applications. For gaming purposes, however, the NPU brings nothing to the table to improve the experience as of 2024. If anything, it's arguably detrimental as raw CPU performance has dropped when compared to the Core i9-13900HK in last year's x16 R1 since precious die space has been reserved for the new neural processor.
The Alienware x16 R2 introduces new Meteor Lake-H CPUs with an integrated NPU for compatibility with future Windows AI features. Unfortunately, raw gaming performance has suffered as a result.
The generally slower performance has also led to lower power consumption and longer runtimes than the original launch model. However, the target gaming enthusiasts who like to buy Alienware are probably not very excited about trading in performance for battery life. Such a move would have been more acceptable on the lower-end Dell G series instead.
We recommend considering the original Alienware x16 R1 since the x16 R2 doesn't offer any new GPU options, display options, or even chassis colors or external changes. The CPU update is only desirable for those who want to "future-proof" their workspace with the integrated NPU.
Price and Availability
Dell is now shipping the Alienware x16 R2 starting at $2100 for the Core Ultra 7, GeForce RTX 4060, standard keyboard, and 1600p240 IPS configuration or up to $3500 if configured with the Core Ultra 9, RTX 4090, and mechanical keyboard.
