This Legion Pro 7i stands out as a high end gaming and AI laptop with a 16 inch 2.5K 240Hz OLED screen, RTX 5090 graphics, and enough memory and storage for heavy local workloads. The machine is described as unusually silent and cool for its specs, and the 5090 plus 64GB RAM setup is praised for local AI, video, and image generation. The main caveats are that the laptop 5090 is power limited and much slower than a desktop 5090 in some workflows, and Thunderbolt 4 instead of Thunderbolt 5 is a deal breaker for some. It looks strongest for portable performance when the workload fits inside 24GB of VRAM.
Common Questions (5)
For gaming, 32GB is usually enough and 64GB is not expected to help much. For local AI, video, or heavy multitasking, 64GB can be useful because system RAM and VRAM can both get maxed out, and 32GB was reported as not enough for faster video generation and large model downloads.
No. The laptop 5090 is described as using the desktop 5080 die with 24GB VRAM and a 150W power limit, and real workloads can be much slower than a desktop 5090; one example was 30 seconds on desktop versus 240 seconds on the laptop for the same 5-second 1080p clip.
It can stay surprisingly quiet and cool under gaming loads, with one owner describing it as far less noisy and hot than prior gaming laptops. That said, the 5090 is still power-limited in a laptop chassis, so sustained performance depends on cooling and power delivery.
No Thunderbolt 5 is mentioned, and the lack of it was a deal breaker for some shoppers. The laptop is also called out as having only Thunderbolt 4.
The 400W brick may not be enough to keep the 5090 at optimum performance by itself, so battery health matters more on the 5090 model. A healthy battery or a battery warranty is recommended if you want to avoid performance loss over time.

How much did your 5090 laptop cost? Is this a good value for 5090 laptop?
More than you asked for but I'm sharing this because I ran into issues you might face when building a local AI stack. I should have researched deeper before buying, but I learned a lot through trial and error. My goal was to avoid renting GPUs or buying an RTX 6000, so I optimized for consumer hardware (RTX 5090 Laptop + Desktop 5090 + M5 Max lol).
too lazy to re-read again and fix some of the formatting.
1. The Core Problem: Resource Contention in my use-case
Running local LLMs, image generation, and video generation simultaneously on a single machine creates severe bottlenecks, even with 24GB or 32GB of VRAM.
The Conflict: When running ComfyUI (media) and LM Studio (LLMs) together, they fight for VRAM and GPU cycles. Neither app respects the other's resource limits. Tuning GPU slices is largely ineffective in this scenario.
The "Land Grab": One process will seize VRAM, starving the other. If VRAM fills up, you hit an Out of Memory (OOM) crash.
LM Studio: Smartly stops loading models if VRAM is insufficient. However, if LM Studio is already loaded, it rarely releases VRAM when ComfyUI starts, causing ComfyUI to starve.
ComfyUI: If it crashes due to OOM, it often hangs or pauses (especially if launched via default batch files), killing the workflow until manual intervention.
The Queue Killer: Both apps have internal queues. When running separately, this works well. When running together, they don't share queues. They each launch one generation, slowing the machine to a crawl or triggering OOM errors.
Performance Note: Even with a Desktop RTX 5090, heavy generation (30sā600s+) blocks the GPU entirely. Nothing else can run on the GPU during this time.
2. Hardware Constraints & Model Limits
A. Laptop RTX 5090 (24GB VRAM)
LLMs: Limited to ~18ā20B parameter models.
Qwen 3.5 (9B): Runs well.
Gemma 4 (20B): Usable but unsatisfying for complex tasks.
Qwen 3.6 (27B/35B): Will not fit in VRAM. If forced into system RAM, it becomes painfully slow, so I removed these models to prevent accidental loading.
Images/Video: Works, but you must use the --low-vram flag in ComfyUI to prevent OOM. I used this for LTX video models. While newer low-VRAM workflows exist, this was a necessary workaround at the time.
Concurrency: Local LLMs are significantly slower than online models (~100 tokens/sec for 35B). You cannot run multiple simultaneous coding sessions or sub-agents. For real development, I rely on online APIs for concurrency.
B. Desktop RTX 5090 (32GB VRAM)
Better Capacity: Can handle larger models than the laptop, but still faces OOM risks during long video generations.
System RAM is Critical: I observed my desktop using all 32GB of system RAM. Upgrade to 64GB+ if you can (this will drive the price to ~$4000). If local LLMs overflow VRAM, they will bleed into system RAM. More system RAM prevents crashes during these overflow events.
Performance: I hit ~200 tokens/sec on a 35B Qwen model. While fast for a single stream, it lacks the concurrency of online APIs.
How I overcome OOM hangs or other problems...
3. My Solution: The "Watchdog" Strategy
To run unmanned tasks overnight without babysitting the machine, I implemented a custom Watchdog Wrapper.
Priority Hierarchy: I prioritize Image/Video generation over LLM requests. Local media generation is significantly faster on NVIDIA chips than on my Mac.
The Watchdog Script Workflow:
Monitor: Watches memory and process status.
Kill Switch: If a ComfyUI request starts, the script instantly kills LM Studio to free up VRAM. I don't care about pending LLM requests; they are negligible now (mostly used for Meta prompting only now).
Auto-Recovery: If ComfyUI crashes due to OOM (which happens occasionally with long video clips >30s), the script detects it and automatically restarts ComfyUI. This allows for smoother, longer generations without manual stitching.
Restore: Once ComfyUI finishes, it restarts LM Studio to handle any pending LLM requests.
4. Why I Don't Use My Mac for LLMs - lol I mean I do use it but not every single time and definitely not for normal coding sessions!.
Speed: Even with 128GB of RAM, running large models like Qwen Coder Next (80B) or Qwen 27B is painfully slow (~20 tokens/sec). QCN was faster, I think 60 tks?
Frustration: Watching a local LLM process prompts and generate tokens one by one is too slow for active coding.
Strategy: I use the M5 Max for general tasks and lighter LLM inference, but I rely on online models for:
Real-time coding assistance.
Running sub-agents (Hermes/OpenClaw).
High-concurrency tasks (5+ simultaneous requests).
someone mentioned something about VMs. lol
VMs: I run VMs on my Mac (not the RTX machines) because the Mac has more CPU cycles and RAM available. ie: I host Hermes in a VM on the Mac, which calls local LM Studio on the Mac for a semi-local setup. However, true "local" agents are useless without internet access for external tools. my other true 24/7 hermes agent will use an online model. I have general sub already and I can use it until it's done.
Is Local AI GEAR Worth It?
For Learning: Yes. It allows for rapid iteration and experimentation.
For Cost: I generated ~3,000 video clips locally. Doing this via online APIs would have cost $1,000ā$1,500.
As online subsidies decrease and prices rise, local hardware is becoming cost-effective.
For Privacy/Uncensored Use: Not necessary for me, as I don't fear data theft from online APIs and there's no porn coming out of my RTX GPUs.
For Coding: No. Online APIs still win on speed and concurrency.
6. Final Recommendation
If you need portability: The Laptop 5090 is great for coding on the go, but the battery dies instantly under GPU load.
If you need power: The Desktop 5090 is a workhorse, but ensure you have 64GB+ of system RAM.
Don't splurge blindly: If you plan to do overnight processing or heavy experimentation, the Watchdog strategy and proper hardware configuration are essential. Without them, you will spend more time fixing crashes than generating content. Unless someone else has a better strategy, I just decided to create something that works for me.
I have some algo to load distribute image and video requests to both machines also but that's something you can build. All of my machines are always connected to my Macbook no matter where I am also. I can generate a lot of nice graphics for example and I've them for "real work" at times.
Of course you can use nano banana and it would be cheaper but sometimes I just auto-generate 10-100 concept prompt variations and I can go back and just pick a good one I liked best. It will cost money and hit rate limits with Gemini or OpenAI's image models. There are also super cheap online image services like 2 cents a picture so ROI is very very slow. I also built app interfaces so I can create image/videos (without going to Comfyui). Again, existing online services are available, I just feel like replicating it as part of the learning just checking off a box on something I know how to do.
yes, I typed out the key points then AI-edited it but still needed some manual editing.
oh the only thing Mac is good for LLM is very very large models but I really have no need for it that. the 128GB Ram is overkill, I could have gotten away with 64GB since I doubt I will go past 35B model use on the Mac.
Any image / video generation will suck on the Mac compared to RTX GPUs. don't buy a Mac at all for content generation. I don't even bother installing ComfyUI on the Macbook despite it is M5 Max 40GPUs because I can just route image/video requests to my RTX machines - they are always connected together as long as I have internet access on my mac.
Basic use you can expect is to run agents like Hermes and openclaw. I do both to try both. I was going to try coding but coding with local model is not fast enough for me so I would use it on airplane only. But last time I was on a pain, the wireless was 20+ mbs. I think the airplane was on starlink. Haha
I am experimenting with diff videos. Education. Explainer. Music videos. Music generation Some stuff for trading. News type of videos etc. nothing good enough to share but enough make all this cost inconsequential

How much did your 5090 laptop cost? Is this a good value for 5090 laptop?
5090 Desktop was $3600? NEW (32GB, 1TB) - I just remote access this as it sits in the corner.
Should have probably just upgraded RAM from factory, ram prices went up higher since I got this machine in mid March. I have since added 32GB more RAM and will add another 2TB stick I already have since I ran out of space due to all of the models I was downloading and testing - the big ones are the video/image with all of the text encoders etc etc that you have to and 32GB was not enough, needed more to make it run a bit faster due to video generation.
Some people say it's a desktop 5070 TI (with 24GB instead of 16GB)
"The NVIDIA RTX 5090 laptop GPU performs roughly equivalent to a desktop RTX 4070 Ti Super or a desktop RTX 5070 Ti. While it bears the "5090" name, it actually utilizes the desktop 5080's silicon (GB203) and provides roughly 50-55% less performance than the desktop 5090 due to power constraints"
It says 50-55% here but the same video I run on both desktop and laptop (same system ram 64GB).
desktop 5090 does it in 30 seconds (5s clip generation, 1080p)
laptop 5090 does it in 240 seconds. -- VRAM difference + pure processing power difference. It was a lot slower than 50% speed as some woudld say based on raw specs. So the answer is it depends on what you are running is my own conclusion.
straight up text LLM that fits inside of 24G VRAM then you can probably see closer to the 50% performance difference.
lol well, was seriously contemplating this deal but Memorial Day is only 2 weeks out.
Just saw this thread https://www.reddit.com/r/GamingLa...em_p
