Tbh it’s mildly surprising they even removed NVENC considering the overall size of the chip (in the absolute we are only talking about low-single-digit mm2 savings) and then H100 is still advertised and has features targeting VM graphics/visualization still… remember they also still put a full graphics pipeline with ROPs/TMUs on the chip, just no actual display hardware.
