Video Streaming Performance

  • Video streaming rates are dependent on several factors beyond the AccuStream board.
  • The AccuStream Express boards can run in PCIe x4, x8 and x16 slots.
  • The AccuStream boards can run in PCI 32 & 64 bit slots.
  • For fastest streaming rates and data transfers, PCIe x4/x8/x16 is recommended.
  • System processor, memory & disk speed all contribute to transfer rate speeds.
  • For uncompressed 1080p60 streaming to disk, we recommend a fast i5/i7/Xeon processor, at least 2GB of RAM, and striped RAID disk drives.
  • Below are transfer rates to memory on "typical" PCI 32 & PCI 64 bit machines that perform at 125 MB/second transfers and 250 MB/second transfers respectively, as well as performance on "typical" PCIe x4 systems (500-700 MB/s). Your performance may vary on slower machines.
