  • Fusion 18.1 Quizz

    Here are some Questions to test your knowledge about Fusion inside Resolve 18.1

    (suite…)

  • Resolve GPUs bench

    Hardware and Software

    All the tests use DaVinci Resolve Studio 16.1.1
    The Project is a Simple Timeline with 3 BRAW (4.6K) heavily graded
    The results are in « fps » (frame per second)

    • Imac 2019 – Core i9 8 cores 3.6 Ghz – RAM 64 GB – Pro Vega 48 8GB
    • Hack X299 – Core i9 12 cores 2.9 Ghz – RAM 32 GB – RX 5700XT 8GB
    • Hack X299 – Core i9 12 cores 2.9 Ghz – RAM 32 GB – RX 5700XT 8GB & GT 710 2GB
    • Hack X299 – Core i9 12 cores 2.9 Ghz – RAM 32 GB – GTX 1080 Ti 11GB
    • Hack X299 – Core i9 12 cores 2.9 Ghz – RAM 32 GB – GTX 1080 Ti 11GB & GT 710 2GB

    With the Dual GPUs, only one is used for compute with Resolve and the other is only for GUI

    The Test Results

    What I learned

    • The Old and Expensive (more than 800€ a year and half ago) GTX 1080 Ti is the best with FHD timeline
    • The Very expensive (RX 580X + 540€) Vega Pro 48 is almost as powerful as the RX 5700 XT
    • The RX 5700 XT (450€) is the best for UHD timeline
    • For AMD GPU, the GUI has a small impact on performances
    • There is something definitely wrong the NVIDIA web driver ➧ You need a dedicated GPU for the GUI

  • Radeon VII vs RX 5700 XT

    Hardware and Software

    All the tests use DaVinci Resolve Studio 16.1.1
    I use the Candle Project
    The results are in « fps » (frame per second)

    Hack X299 SAGE 10G – Core i9 14 cores 3.1 Ghz – RAM 64 GB – RX 5700XT 8GB & Radeon VII 16GB
    I plugged both a Radeon VII and an RX 5700 XT on the motherboard: System info show both use x16 PCIe
    Display is 3440×1440 via DisplayPort

    Test results

    What I learn

    1. RX 5700 XT in a little less powerful than Radeon VII ➧ RX 5700 XT has better price/performance ratio
    2. OpenCl is dead …. slow
    3. Pluging the display on computing GPU has a minor impact on performances (It’s not true with RED RAW GPU debayering for example See the next post)
    4. I can’t figure how Final Cut Pro 10.4.7 select the GPU despite the new preference menu
    5. RX 5700 XT (Gigabyte Gaming OC) is less noisy than the Radeon VII when fully loaded
    6. RX 5700 XT (Gigabyte Gaming OC) is a little wider than 2 PCI slot ➧ multiple GPU difficulties

    After I Superscale (very GPU intensive) the media to 8K and make the project to 8K, to find a if the RADEON VII’s 16G is an advantage. 2 TNR Test give the same result with each computing GPU
