Guides 2
- Check Your GPU's Real PCIe Bandwidth on Linux
See what PCIe link width and generation your GPU actually negotiated (lspci vs nvidia-smi), what the numbers should be, and when a downgrade actually matters.
- RTX PRO 5000 Blackwell eGPU on Linux with Sonnet 850T5
Get an NVIDIA RTX PRO 5000 Blackwell working as a Thunderbolt 5 eGPU under Linux — the proven boot/hot-plug sequence, the Sonnet 850T5 PCIe topology, small-BAR behavior, every workaround and its sourcing, BIOS outcomes.
Benchmarks 2
- RTX PRO 5000 Blackwell — llama.cpp Benchmarks
Prompt processing and token generation speeds for popular GGUF models on dual RTX PRO 5000 Blackwell, with full reproduction setup.
- PCIe 5.0 x8/x8 Isn't Enough: Testing GPU P2P Bandwidth on Z890
Two CPU-attached Gen5 x8 GPUs that move only 5.3 GB/s GPU-to-GPU in one direction and 2.0 GB/s in the other — measured with a custom probe and NVIDIA's p2pBandwidthLatencyTest, and why PCIe generation and width alone mislead.
