The high-end Framework has 128GB, just like Project DIGITS. VRAM size has always been the problem, so I'm not comparing these APU SBCs to PCIe GPUs.
The comment was more about the timing of the announcements. Maybe Framework should have waited a year and then use an RDNA 4-based APU, developed and marketed in close coordination with AMD. The competitors are Apple and Nvidia, where both build their own chips and get to design their entire systems.
RDNA 4 has a 2x performance gain over 3.5 (4x with Sparsity) at FP16.
It just makes it all harder (the picking and choosing). Let's see what Project DIGITS brings once it launches.
