I just got an Intel Arc A770 LE with 16 GB VRAM. There are pros and cons, as expected. As this series of GPUs (the ARC or Alchemist series) is relatively new compared to NVidia and AMD graphics, it seems like a general discussion thread is appropriate. So, here it is. Feel free to offer observations, concerns, test results, impressions, or even advice (although that is always risky on a board with many very experienced video editors).
I will start with initial pros and cons...
- Good performance per dollar, as the Vegas Pro support for QSV rendering is robust
- Much faster than the card I replaced (AMD Radeon 5600XT), for one comparison
- Supports AV1, which Vegas Pro will also hopefully support soon
- The implementation of HDMI 2.1 is via something called "PCON," which Intel describes as not a genuine HDMI port, and therefore Intel does NOT allow user selection of 10-bit or 12-bit color (thus, HDR is RGB Full, 8-bit dithering). From what I have read, such 8-bit dithering is comparable to 10-bit 4:2:0, but this limitation on a new GPU seems lame.
