Intel Arc A750 GPU spotted with 16GB memory and a powerful 512-bit bus

An engineering prototype for Intel's ARC A750 graphics card has been discovered, revealing a previously unreleased ARC Alchemist GPU model that Intel contemplated launching. This particular Intel GPU sample is a 16GB ARC A750 unit from Gunnir, which has been acquired by @komenezumi1006.

This unreleased Intel ARC GPU seems to operate without issues. The GPU requires two 8-pin PCIe connectors for power and is labeled as having 16GB of GDDR6 memory over a 512-bit memory bus. In contrast, standard Intel ARC A750 GPUs feature an 8+6-pin PCIe power setup and have 8GB of GDDR6 memory on a 256-bit memory bus.

The GPU's owner has reported that it shows a 256-bit memory bus on GPU-Z. At this point, it remains unclear why this GPU is listed as having a 512-bit memory bus. Our assumption is that this GPU was incorrectly labeled, as it seems someone mistakenly thought that doubling the memory capacity necessitates a corresponding increase in memory bus size.

From the visuals of this GPU, it’s evident that this is not a dual ARC A750 GPU, which would possess two GPU cores and two 256-bit memory buses (totaling 512-bit). As depicted above, this GPU has just one ARC A750 core. If this GPU indeed had a 512-bit memory bus, it would require an entirely new GPU core architecture. Therefore, we suspect the label simply contains erroneous specifications.

It's important to note that this GPU appears to function properly. According to Windows Task Manager, it recognizes the GPU as a 16GB graphics card. Additionally, it seems to work seamlessly with the latest Intel ARC GPU drivers.

The sole 16GB ARC A-series GPU to be launched thus far is Intel's ARC A770, which was made available in both 8GB and 16GB variants. It seems Intel may have intended to release a 16GB ARC B750 GPU as well. If this release had occurred, it would have enhanced the appeal of Intel’s lower-end ARC A750 GPU, though it might have diminished the attractiveness of Intel’s newer ARC Battlemage B570, which only debuted with 12GB of memory.

The recently leaked Intel ARC B770 is grabbing attention, but you don’t need to wait for rumors to turn into reality to enjoy smooth, modern gaming performance. The Intel ARC B570 already delivers excellent value with strong ray tracing support, XeSS upscaling, and reliable performance for today’s most popular titles.
