Nvidia's unreleased RTX 3070 Ti 16GB gets rebuilt by Brazilian modder using GDDR6 chips

Brazilian YouTuber fmklab (Fabian) has successfully recreated a prototype of NVIDIA's unreleased RTX 3070 Ti 16GB graphics card. Originally expected to feature 16GB of VRAM instead of the 8GB in the a... Read original →

This unofficial modification highlights an unmet market demand for high-memory GPU configurations. If NVIDIA had launched the RTX 3070 Ti 16GB as planned, it would have accelerated the adoption of GDDR6X in premium cards, yet current GDDR6-based workarounds suffer from lower bandwidth, limiting performance in AI and VR workloads. From a supply chain perspective, this act underscores NVIDIA’s reliance on suppliers like Samsung, especially amid geopolitical tensions where custom solutions may circumvent restrictions. AMD, if slow to respond, risks losing ground in AI and content creation markets. In the short term, rising demand for high VRAM will accelerate the rollout of RTX 50-series and Blackwell chips. Long-term, such modding trends may foster a new ecosystem of hardware customization, pressuring vendors to improve standardization and compatibility. Additionally, unauthorized performance adjustments could attract regulatory scrutiny, particularly when involving falsified benchmark data.
