With AI chatbots, Big Tech is moving fast and breaking people
Why AI chatbots validate grandiose fantasies about revolutionary discoveries that don't exist. 
© 2025 Ars Technica 11:45pm You don’t need a PCIe 5.0 SSD unless you say ‘Yes’ to these 3 questions
There’s a common misconception about PCIe 5.0 SSDs that since they’re the latest-generation SSD storage and boast faster speed and bandwidth compared to PCIe 4.0 SSD, anyone who gets one is going to experience a big uptick in PC performance.
That’s certainly not the case as we’ve shown by analyzing things like gaming performance. But there are a few exceptions to that rule. In fact, if any of the below statements are true for you, you may well have a justifiable reason for splurging out on a costly PCIe 5.0 SSD upgrade.
Am I working with large datasets?
Scientists and other professionals work with very large amounts of data — often terabytes but sometimes even petabytes in size.
PCIe 5.0 SSD doubles the bandwidth of PCIe 4.0 SSD delivering theoretical speeds of 14,000MB/s for reads and 12,000MB/s for writes to disk. These faster transfer speeds can help prevent one of the biggest problems data scientists have to deal with nowadays — that is, the bottlenecks that occur on their PCs loading and preprocessing data from storage.

For data scientists, especially those working with datasets in Large Language Models (LLMs), tasks like running complex queries on a database, accessing files while training models, or saving large model checkpoints should be much snappier with a PCIe 5.0 SSD, therefore reducing the time workers are idle and likely therefore also boosting productivity.
Am I a video editor, 3D animator, or designer working with very large files?
If your job title is 3D animator, designer, or video editor and, again, you’re working with large files, then a PCIe 5.0 SSD is likely to make your workflow much quicker.
That’s especially the case if you work with 4K or even 8K video files, where the speed and bandwidth increases will likely translate to smoother timeline scrubbing and faster rendering.
Do I want to future-proof my hardware for gaming?
Right now, there’s not much of an advantage gaming with a PCIe 5.0 SSD over a PCIe 4.0 SSD, but as hardware and software applications continue to evolve, it’s likely they will better take advantage of the speed and bandwidth benefits of PCIe 5.0 SSD for gaming.
That looks to be the case with the emerging technology of DirectStorage that reduces load times and improves asset streaming in games, especially data-heavy open-world RPGs.
DirectStorage allows games to load data directly from the SSD to the GPU, thereby bypassing the CPU. While the technology works on PCIe 4.0 SSDs, PCIe 5.0 SSDs are better suited to utilize the DirectStorage technology when it becomes more widespread.

The Acer Predator Helios Neo 16S AI is a 16-inch gaming laptop with solid hardware for a reasonable price. But if you’re looking for a true “AI laptop,” this isn’t it. The neural processing unit (NPU) is too slow to handle Microsoft’s Copilot+ PC AI features nor is it ready to run the most current AI tasks. Many buyers don’t realize that modern “AI laptops” often fall short of Microsoft’s advertised standards.
Like other gaming laptops rebranded as AI laptops, this machine would excel at GPU-based AI tasks, but no more than any other gaming laptop. With 12 GB of VRAM, the Nvidia RTX 5070 Ti GPU here isn’t ideal for local AI models. (For example, OpenAI’s new gpt-oss-20B model is intended for GPUs with at least 16 GB of VRAM.)
Moving beyond the AI branding, this is a fine laptop — if we treat it as a gaming laptop and not an AI laptop. And this OLED display at less than $2,000 is extremely impressive. So, for the rest of this review, I’ll just treat it like a gaming laptop.

Acer Predator Helios Neo 16S AI: Design and build quality
IDG / Chris Hoffman
The Acer Predator Helios Neo 16S AI is a 16-inch gaming laptop that lands somewhere between the thinnest gaming laptops and the chunkiest ones. At just under five pounds, it’s still plenty portable for a gaming laptop. It’s all black, aside from a reflective Predator logo on the lid and a silver logo on the keyboard tray. The good news is that there’s no “AI” logo anywhere on this machine.
While Acer doesn’t specify the materials in its reviewer’s guide, the lid appears to be made of a black aluminum, with much of the rest of the machine made of a black plastic. It feels solid. The hinge also feels nice and smooth, and it’s easy to open with a single hand.
While the keyboard lights up with multicolored LEDs if you want it, the rest of the machine in its “Obsidian Black” color scheme is restrained, and it could pass for more of a professional laptop than a gaming laptop. There are no light bars or other effects elsewhere on the laptop. That silver “Predator” logo below the keyboard marks it as a gaming laptop, however.
It’s a solid laptop. It feels sturdy, and the plastic finish doesn’t feel cheap. At an inch thick, it’s a reasonable thickness for a gaming laptop. But it doesn’t feel quite as luxurious to the touch as an all-metal laptop chassis.
Acer Predator Helios Neo 16S AI: Keyboard and trackpad
IDG / Chris Hoffman
The Acer Predator Helios Neo 16S AI has a full-size keyboard complete with a number pad (there’s plenty of room for it) and four zones of RGB LED backlighting. That customizable backlighting lets you set up colorful effects without the cost of including more expensive per-key RGB backlighting.
With 1.5mm of key travel, this is a standard membrane-style chiclet keyboard on a gaming laptop of this size. There’s plenty of room for enough key travel to make the keyboard feel nice without any extra tricks. It feels fine — not mushy — but it doesn’t feel as unusually snappy as when manufacturers go the extra mile to include a mechanical keyboard or one with extra actuation force.
The trackpad is a good size, smooth, and responsive. The surface isn’t as smooth as a glass touchpad, and there’s perhaps a little more friction than on some other trackpad finishes I’ve used recently — plus the click-down action lands with a bit more of a “thunk” than a “click” — but it’s fine. It’s a standard touchpad, but nothing that stands out against its competitors. I game with a mouse, anyway, and I’d be happy using this while I wasn’t gaming.
Acer Predator Helios Neo 16S AI: Display and speakers
IDG / Chris Hoffman
The Acer Predator Helios Neo 16S AI has a 16-inch 2560×1600 OLED display with a 240Hz refresh rate and up to 400 nits of brightness (peaking a bit higher in HDR mode.) It supports HDR and Nvidia G-Sync, too.
The display looks great — I’m a sucker for a good OLED. I’m excited to see an OLED with such a high refresh rate, too. For years, it felt like you had to pick between OLED or a high refresh rate on a gaming laptop. You can get displays that are brighter or even higher resolution on a gaming laptop, but this one looks good with the deep blacks you’ll find on an OLED.
While this is very nice OLED, it’s not the best one I’ve seen. While playing Doom: The Dark Ages, the blacks on this OLED display looked nice and deep, but these aren’t the vivid colors and high brightness I normally see on an OLED-powered laptop. In a lot of ways, it reminds me more of a good IPS display. That’s not a surprise due to that 400 nits brightness.
The blacks are nice and deep, but the colors aren’t as vivid as I see on brighter OLEDs. As an OLED, it’s a little glossy and prone to reflections, and that can be an issue in a bright room, more brightness usually helps overpower these reflections.
I test the speakers on every laptop I review by playing Steely Dan’s Aja and Daft Punk’s Get Lucky. The Helios Neo 16S AI’s two stereo speakers delivered plenty of volume. They did a better job in Get Lucky than in Aja with its precise instrument separation.
But the upper midrange was a little harsh, especially at higher volume settings — something that really comes through in sounds like the singing in Get Lucky‘s chorus. I found the upper midranges fatiguing after just a few minutes in Doom: The Dark Ages, too. I don’t like the way the speakers sound, and I would really want to use headphones while gaming.
Acer Predator Helios Neo 16S AI: Webcam, microphone, biometrics
The Acer Predator Helios Neo 16S AI has a 1080p webcam that looks fine for a gaming laptop. In fact, I’d say it’s on the better side for a gaming laptop, though the color and general image quality aren’t up there with business laptops optimized for video conferencing.
Since Acer is pushing AI features for the webcam and microphone, it’s worth noting that the “PurifiedView” button in the PredatorSense app’s “Experience Zone” just opens Windows Studio Effects webcam settings — you’ll get these particular effects (automatic framing, eye contact, and background blur) on basically any laptop with this NPU. And you’ll get more on a Copilot+ PC that delivers extra features.
The microphone setup was on the quiet side and not particularly high-quality. That’s normal for gaming laptops, but Acer markets this as a three-microphone setup for crystal-clear voice quality. You’ll probably be using an external microphone, anyway. This machine has Acer Purified Voice features you can tweak in the PredatorSense’s “Experience Zone,” and they’re an improvement over no effects. However, stronger microphone hardware would deliver a better voice input experience than these trendy AI effects do.
You don’t need an “AI laptop” for background noise removal, anyway.
This machine has an IR camera for facial recognition with Windows Hello, so you can sign in with your face. As usual on modern laptops, it works well.
Acer Predator Helios Neo 16S AI: Connectivity
IDG / Chris Hoffman
The Acer Predator Helios Neo 16S AI has a good collection of ports that are positioned well. But it also has one of the big problems I tend to see on laptops like these — USB port confusion.
On the left side, the machine offers an Ethernet jack, a USB Type-A port, a microSD card reader, and combo audio jack. On the right side, it’s got two more USB Type-A ports.
On the back, you’ll find a DC power in jack, HDMI 2.1 out, and two USB Type-C ports (one is Thunderbolt 4 and one is USB 3.2). That’s a great location and means cables like power in and video out are coming out the back of your laptop and aren’t in the way of your mouse and other things on your desk.
The annoyance is the usual USB port confusion. On the back, one of the USB Type-C ports is a Thunderbolt 4 port while the other operates at USB 3.2 speeds. You’ll need to keep an eye on which is which if you have Thunderbolt 4 devices or you’ll find them operating at reduced speeds.
This laptop features Killer Wi-Fi 6E hardware and Bluetooth 5.4 support, and it thankfully has that 2.5 Gbps Ethernet port for wired networking. It’s disappointing that Acer skipped Wi-Fi 7 here. It’s not a big deal, but Wi-Fi 7 support would make it more futureproof.
Acer Predator Helios Neo 16S AI: Performance
I put the Acer Predator Helios Neo 16S AI to the test in Doom: The Dark Ages, and it performed well — as it should with this CPU and GPU!
Under load, the fans aren’t unusually loud for a gaming laptop. They blow hot air out of both the back and sides. I’d prefer if they only blew it out the back. The keyboard can also get a little toasty, especially in the middle.
As always, we ran the Acer Predator Helios Neo 16S AI through our standard benchmarks to see how it performs.
IDG / Chris Hoffman
First, we run PCMark 10 to get an idea of overall system performance. This is an overall system benchmark, but the CPU is a huge factor here. The Acer Predator Helios Neo 16S AI delivered a solid score of 8,320 thanks to its speedy Intel Core Ultra 9 275HX CPU.
IDG / Chris Hoffman
Next, we run Cinebench R20. This is a heavily multithreaded benchmark that focuses on overall CPU performance. It’s a quick benchmark, so cooling under extended workloads isn’t a factor. But, since it’s heavily multithreaded, CPUs with more cores have a huge advantage.
With an average multithreaded Cinebench R20 score of 13,072, this laptop was a bit behind some competitors with the same CPU, possibly suggesting cooling may be a factor.
IDG / Chris Hoffman
We also run an encode with Handbrake. This is another heavily multithreaded benchmark, but it runs over an extended period. This demands the laptop’s cooling kick in, and many laptops will throttle and slow down under load.
The Helios Neo 16S completed the encode process in an average of 562 seconds. That’s over nine minutes. Again, we see it slipping behind similar laptops that presumably have better cooling systems and need less throttling under load.
If I were approaching this as an AI laptop and saying you might be looking to do CPU inference, I’d point out this is a real issue — you’d want a laptop with better cooling to run heavy CPU-crunching tasks for extended periods of time. (But, since we’ve left the idea of this being an AI workstation behind, it’s fine and likely won’t have a huge effect on gaming performance.)
IDG / Chris Hoffman
Next, we run a graphical benchmark. First, we run 3Dmark Time Spy, a graphical benchmark that focuses on GPU performance. The Nvidia RTX 5070 Ti GPU here produced a Time Spy score of 13,528. A benchmark like this one is all about the GPU.
What’s interesting here is the RTX 5070 Ti in this machine doesn’t pull very far ahead of the RTX 5070 in the Alienware 16X Aurora. It’s ahead, but only by a little bit. Comparing on-paper GPU speeds, it should be ahead by a lot! The cause is likely the TDP. In this machine, the RTX 5070 Ti is limited to 115 W max, so it can’t take full advantage of the 5070 Ti’s theoretically higher performance in the ideal world. (The Alienware 16X Aurora also runs its 5070 at a 115 W TDP.)
IDG / Chris Hoffman
Then, we benchmark some games. We start with Shadow of the Tomb Raider, an older game, but a great way to compare performance across hardware. With an average FPS of 160 in our standard benchmark here, this machine is in line with other similar laptops and even ones with faster RTX 5080 and RTX 5090 GPUs.
IDG / Chris Hoffman
Finally, we benchmark a demanding game. We run the Extreme benchmark in Metro Exodus. With an average FPS of 56 in this benchmark, this comes in roughly where we’d expect to see it — behind RTX 5080 and RTX 5090 laptops.
Again, this is only a hair faster than the RTX 5070 in the Alienware 16X Aurora. While the Acer Predator Helios Neo 16S does have a faster GPU, the advantages are marginal at this TDP level.
Overall, the Acer Predator Helios Neo 16S AI performed fine. But it doesn’t take full advantage of its hardware. The Intel Core Ultra 9 275HX doesn’t deliver the kind of sustained performance it can on competing PCs (likely due to the cooling hardware), for example.
More importantly, while the choice of a faster RTX 5070 Ti GPU looks like a big on-paper win that will deliver faster performance than an RTX 5070, the TDP here means that the GPU in this machine performs similarly to machines with RTX 5070 GPUs running at the high end of what they can manage.
Acer Predator Helios Neo 16S AI: Battery life
The Acer Predator Helios Neo 16S AI has a 76 Watt-hour battery, which is middle of the road for a gaming laptop. Still, it helps keep weight down and you aren’t going to game on battery power anyway.
IDG / Chris Hoffman
To benchmark the battery life, we play a 4K copy of Tears of Steel on repeat on Windows 11 with airplane mode enabled until the laptop suspends itself. We set the screen to 250 nits of brightness for our battery benchmarks. This is a best-case scenario for any laptop since local video playback is so efficient, and real battery life in day-to-day use is always going to be less than this.
Also, since this laptop has an OLED screen that doesn’t have to use extra power to display the black bars around the video, that gives it a bit of an edge against competing laptops with IPS displays on this test.
The Acer Predator Helios Neo 16S AI lasted for an average of 371 minutes in our benchmark — that’s just over six hours. You’ll get less in the real world, so this laptop won’t make it through a workday (maybe not even have a workday) before you must plug it in. That’s standard for gaming laptops with power-hungry Intel Core Ultra 9 275HX processors.
Acer Predator Helios Neo 16S AI: Conclusion
If you want a 16-inch OLED with 240Hz refresh rate for under $2,000, you should seriously consider this machine. Asus’s ROG Zephyrus G16 is another 16-inch laptop with an RTX 5070 Ti, a slower Intel Core Ultra 9 285H CPU, and a 240Hz refresh rate, and Asus’s online store has it at $2,799 as I’m wrapping up this review.
The Acer Predator Helios Neo 16S AI tries a few other gimmicks. The “AI” branding isn’t a reason to buy this PC over another gaming laptop. And the RTX 5070 Ti GPU — a win on paper — is held back and doesn’t deliver the theoretical high-end performance it might.
If you aren’t excited by this OLED at this price, I recommend you consider other options. This display at this price is this machine’s standout feature, not AI.
