In an intriguing twist, a modified version of NVIDIA’s GeForce RTX 4090 has surfaced, boasting an eye-popping 48 GB of VRAM. However, early benchmarks reveal this souped-up graphics card is best left to handle the demanding challenges of AI workloads, rather than gaming enthusiasts looking to max out their rigs.
While the scarcity of AI accelerators continues to pose challenges, innovative modders have found a way to boost the VRAM on the RTX 4090—doubling it to a hefty 48 GB. Although this modification theoretically enhances performance for artificial intelligence applications, it doesn’t benefit gamers. Russian YouTuber MKA has taken the deep dive into this altered RTX 4090, showcasing a modified PCB and confirming its specialized purpose.
The modified card sports a unique-looking blower-style design with curious NVIDIA branding. It seems the graphics board underwent specific customization to accommodate the extra GDDR6X VRAM modules. This required a dual-sided memory approach not supported by the original design, pointing to possible structural weaknesses.
Upon putting this powerhouse through synthetic tests like Uniengine, the results were intriguing. The modified RTX 4090 generated noise levels as high as 65 dB, far exceeding those of a standard model. Yet, despite its loud hum, temperatures stayed relatively under control, usually staying around the 70°C range and peaking at 86°C. Even with its extended VRAM, gaming performance improvements are minimal, rendering this version unsuitable for conventional gaming.
MKA’s further tests focused on AI models, where the RTX 4090 truly shined. Using it for running advanced AI applications like Google’s Gemma-2, the modified GPU performed smoothly. It’s clear that the expanded VRAM and its ability to run complex tasks without hiccups make it ideal for AI researchers and data scientists, particularly given the scarcity of standard AI accelerators.
Interestingly, these modded GPUs are primarily available in Chinese markets, where demand is sky-high. The price tag reflects that demand, as the 48 GB variant costs approximately $3,400—outpricing even the GeForce RTX 5090. It seems for those seeking to harness their power for AI operations, these unconventional cards offer a valuable, albeit pricey, solution.
