Key Takeaways
1. A DIY handheld device powered by an RTX 4090 can run Cyberpunk 2077 at 4K 60 FPS.
2. The handheld features a 12.5-inch 4K IPS touchscreen, Intel Core i9-14900HX processor, 64 GB of RAM, and a 2 TB SSD.
3. The device’s GPU operates at a TGP of 174 W, similar to a gaming laptop, and is powered by a standard gaming laptop charger.
4. In addition to Cyberpunk 2077, it can run God of War (2016) at 110-120 FPS with smooth gameplay.
5. The system maintains impressive thermal performance, with the CPU and GPU temperatures staying around 67°C and 72°C, respectively.
I never imagined that gaming in 4K on a portable device would become a possibility, but then I came across a video from the YouTube channel ‘NITTRX.’ In this clip, the creator demonstrated a handheld device powered by an RTX 4090, playing Cyberpunk 2077 at an impressive 4K 60 FPS.
Impressive Showcase
The video is fairly brief, yet it highlights the DIY RTX 4090 handheld remarkably well. The YouTuber has used the mobile version of the RTX 4090 chip, equipped with 16 GB of GDDR6 VRAM, which is shown when the specifications are revealed at the video’s start. During gameplay, it’s clear that the GPU operates at a TGP of 174 W, similar to the laptop version of the RTX 4090. A regular gaming laptop charger can also be spotted in the video, supplying power to the DIY handheld.
Specifications Unveiled
In terms of specifications, this RTX 4090 handheld boasts a 4K IPS touchscreen display measuring 12.5 inches, the same kind previously found in a Dell Latitude 12 E7275. Additionally, it features an Intel Core i9-14900HX processor, 64 GB of RAM operating in quad-channel mode, and a 2 TB SSD. Essentially, it’s like a full gaming laptop packed into a compact 12.5-inch frame.
When we look at gaming performance, the DIY handheld was able to run Cyberpunk 2077 at approximately 4K resolution with high or maximum graphical settings. I’m not entirely sure of these specifics because the creator doesn’t clearly display them in the video. Nevertheless, with the Steam performance overlay showing about 8.3 GB of VRAM in use, it’s reasonable to think that the game is indeed running at high graphics and resolution. The frame rate was around 60–70 FPS.
Gaming Performance Analysis
The YouTuber then played 2016’s God of War, achieving between 110 and 120 FPS with smooth gameplay. A particularly interesting aspect was the thermal performance: the 14900HX was sitting at about 67 degrees Celsius, while the RTX 4090 reached 72 degrees Celsius. Fitting such high-performance components in a tiny chassis is already quite amazing, but managing to keep them cool is an even more impressive achievement.
The YouTuber continues to explore more gaming features throughout the rest of the video, which is linked below. I highly recommend watching it, as a DIY RTX 4090-powered handheld is definitely something everyone should witness to believe.
