Intel Arc A750 prototype spotted with 16GB VRAM — Engineering sample made by Gunnir sports sticker claiming a 512-bit memory bus

A prototype of the Intel Arc A750 GPU with 16GB VRAM and a 512-bit memory bus has been spotted, suggesting a potential upgrade from the original 8GB version. The prototype, made by Gunnir, features stickers indicating it's an engineering sample and shows up with the full 16GB VRAM in Task Manager. While it lacks benchmarking data, the presence of two 8-pin PCIe power connectors and Intel Arc Sample stickers hint at Intel's experimentation with a 16GB A750 variant. This prototype remains an intriguing glimpse into potential GPU development that never materialized in the market.
