I have had the Alienware 18 Area-51 for a month now, and I have used it for all sorts of tasks. Standing at this point in early November 2025, this article aims to discuss two things from a technical perspective. First: How will graphics processing technology continue to evolve? Second: Compared to traditional desktop tower PCs, who exactly is the target audience for PCs in the form of heavy gaming laptops?
A little background. The configuration and testing-related info for my Alienware 18 Area-51 are as follows:
- Graphics card: RTX 5080 Laptop GPU, 16 GB VRAM, maximum power draw 175W.
- Processor: Intel Core Ultra 9 275HX
- Memory: 32GB - 2x16GB DDR5 7200MT/s XMP
- Test setup: Laptop placed flat at room temperature, outputting a discrete-GPU signal to an external 4K 120Hz display via HDMI 2.1.
- Theoretical maximum system power draw is 275W; the power adapter is 360W.
First, I conducted an experiment on this device based on the Black Myth: Wukong benchmark tool. I wanted to explore three themes through this test:
- Where do DLSS-like graphics computing ecosystems and traditional rasterization ecosystems stand within the entire graphics processing pipeline?
- Do the thermal design and performance output of high-performance, heavy-duty gaming laptops truly complement each other?
Here is the experiment I ran: Please watch the video.
Here is my summary:
- The heat generated by the Alienware 18’s performance output can be effectively exhausted even when the fans are not spinning at full speed. The thermal headroom is completely redundant.
- Note: In all tests, individual core temperatures consistently remained between 60 and 70 degrees Celsius.
- Under the exact same graphics settings, 1440p (2K resolution at 16:9) with DLSS lowered by one preset yields a frame rate 20 to 30 FPS lower than 2160p (4K at 16:9). This conclusion is supported by Tests 2 and 3.
- When minimizing the impact of DLSS and manually disabling frame generation, the frame rate plummets to around 30 to 40 FPS. Even after turning down ray tracing and other graphics settings, the frame rate still cannot exceed 60. This conclusion is supported by Tests 1 and 4.
- Note: Overclocking was not enabled in Test 1. However, the PC was still receiving adequate power in performance mode. Enabling overclocking would most likely not drastically change the results.
After the experiment, I acknowledge there are still many unrigorous and uncontrolled variables—such as the VRAM and performance overhead used by OBS, or, as mentioned above, the fact that overclocking wasn’t enabled in Test 1. It will be necessary to conduct another round of testing in the future. However, the conclusions drawn so far are basically consistent with my everyday observations over the past month. So, with about 70% confidence in my own analysis, I’d like to share some of my views. These opinions might be overturned by myself at any time in the future, or they might be further confirmed as new arguments. Readers are advised to take them with a grain of salt.
Regarding the thermal issues of high-performance gaming laptops in 2025, let’s take the Alienware Area-51 18-inch—arguably one of the best in this regard. Even after overclocking, the core component temperatures remain below 70 degrees. This clearly indicates that slightly lowering the fan speed wouldn’t have a significant negative impact. Therefore, there should be an option to make the machine quieter without sacrificing performance. However, the current thermal management strategy does not give me this alternative. I don’t know if Dell plans to optimize this strategy in the future, or push a BIOS update allowing users to manually adjust fan curves while overclocking.
By analyzing the performance of Groups 2 and 3, both of which I recorded based on Black Myth: Wukong’s recommended settings, 1440p with DLSS lowered by one preset yields 20 to 30 fewer frames than 2160p. This demonstrates that current DLSS settings have a greater impact on the game’s output frame rate than native resolution settings do. In the future, especially for so-called AAA games competing on visual fidelity, the industry will increasingly rely on DLSS or other AI-based algorithms and dedicated tensor cores, rather than traditional rasterization performance.
Based on my personal gaming experience over the past month, the blurriness and mosaic-like ghosting introduced by DLSS are extremely severe when playing on ultra graphics settings. Its negative impact on visual clarity far outweighs the performance benefits. The situation only improves when you lower base settings (especially ray tracing and environmental draw distance) and crank the DLSS slider up past 80. But then again, AI algorithms still fundamentally rely on traditional rasterization capabilities. Only when the base render quality is solid enough to support the AI in accurately “guessing” the intermediate frames does DLSS actually do more good than harm.
As for the RTX 5080 laptop GPU operating under 200W, even though it packs a respectable number of CUDA and Tensor cores, it still loses out to the desktop RTX 5070. The fact that a desktop RTX 5070 Ti outperforms a mobile RTX 5090 is something I’ve seen proven in countless benchmarks. Meanwhile, a custom PC built with that desktop card will undoubtedly cost less than almost any gaming laptop equipped with an RTX 5080 mobile GPU.
In reality, the sheer CUDA core count of an RTX 5070 Ti is lower than that of an RTX 5090 mobile.
The RTX 5090 Laptop GPU features 10,496 CUDA cores and 24GB of VRAM, whereas the RTX 5070 Ti only has 8,960 CUDA cores and 16GB of VRAM. For context, the desktop RTX 5090 boasts a massive 21,760 CUDA cores with 32GB of dedicated VRAM.
If we look past the numbers and consider the hardware hosting these chips: the RTX 5090 Laptop is soldered onto an integrated motherboard with a 200W limit, while the RTX 5070 Ti sits on a dedicated PCB built to handle a 400W load. Although the RTX 5090 Laptop has 10,496 CUDA cores, its Total Graphics Power (TGP) is strictly capped at 175W–200W (or potentially lower). By contrast, the RTX 5070 Ti’s TGP pushes 300W–350W. In other words, constrained by power limits, mobile GPUs simply cannot achieve the computational performance of desktop GPUs, even if the desktop parts have lower core counts.
So, what is the point of the RTX 5090 mobile GPU’s existence? Here, we have to recognize the non-linear relationship between a GPU’s power draw and its clock speed. To give a highly simplified example: accelerating a core from 1.0 GHz to 2.0 GHz might require triple the voltage and power, or even more. Applying this principle to mobile GPUs, we find that it’s fundamentally flawed to evaluate desktop and mobile chips with the same mindset when severe power limits are in play.
Suppose we want to achieve a specific performance target on a laptop. What we are really balancing is the trade-off between hardware scale and power consumption:
- Suppose we use 7,680 cores and overclock them to extremely high frequencies. We might hit the 175W power wall when we’ve only reached 60% of the desktop card’s performance.
- Suppose we use 10,496 cores running at a lower frequency. In this scenario, each core operates in its most power-efficient range. The combined computational output of these 10,496 cores can achieve the desired performance target without ever slamming into the power limit.
Therefore, the awkward truth about gaming laptops today lies in hardware specifications being bottlenecked by power limits that prevent those specs from fully unleashing their computational potential. Yet, consumers are still paying premium prices for those extra CUDA cores. When you have the freedom to choose a different hardware form factor, would a gaming laptop still be your top choice?
At this point, at least for me, my expectations for the heavy gaming laptop form factor have fallen flat. Even with the 18-inch Area-51—which boasts some of the most robust cooling in its class—its true potential is ultimately hard-capped by power delivery.
I can’t help but wonder: who exactly finds value in the current iteration of gaming laptops? After much thought, perhaps their portability only makes sense for college students shuttling between dorms and home, or professionals who need a single machine for both work and heavy entertainment while commuting. Although I frequently travel between campus and home, I have no real need to game on the go. The money I spent on the Area-51 would have been more than enough to build a custom PC that operates virtually silently while matching its performance, or vastly outperforming it under normal noise levels. That same budget could even buy a standalone desktop RTX 5090—a single card that pulls 550W, which is exactly double the combined maximum power draw of my entire current laptop (275W).
As traditional rasterization performance approaches physical hardware limits, it is bound to hit a major bottleneck. Over time, AI will inevitably be integrated into the very definition of graphics computing, becoming an inseparable core component. NVIDIA currently remains at the absolute forefront of this shift, guarded by the thickest technological moats in the industry. As I look forward to seeing how future graphics processing will better fuse with AI, I also hope to maintain my sensitivity and curiosity toward cutting-edge technology.
