RTX 4000 Blackwell misses key features

NVIDIA's Blackwell branding for workstation GPUs is criticized as deceptive marketing, reserving major architectural breakthroughs like FlashAttention 4 and native NVFP4 tensor support for the datacenter tier. Current software support remains immature, with vLLM regressions and generic Ampere kernel fallbacks relegating the SM120 silicon to "second-class" status without manual clock locking and version pinning. Despite these hardware omissions, community-driven kernels demonstrate that NVFP4 can still outperform AWQ INT4 by 17% by reducing memory bandwidth pressure.
