Justo thank of 8k braw

For 8k.R3D 5:1 24 fps, you need an overclocked i9-7980XE running around 4 GHz all-core just for de-crypting, decoding and decompressing the file in real-time. For the de-bayering in resolve (playback full everyting) in real-time a $400 RX VEGA 64 is enough. RED's R3D is based on JPEG2000 wavelet compression and needs around 4 to 5 times more compute power than CineformRAW with the advantage of around a 20..30% smaller file size.
Example:
RED 8k.R3D 5:1 24 fps ~ 260 MByte/s.
CineformRAW 8k 4:1 24 fps ~ 325 MByte/s to get the same PSNRs (peak signal to noise ratios).
For the RED 8k you need 4GHz on 18c/16tr($2,000 + $200 for cooling) and for the Cineform you have enough with 4GHz on 4c/8tr or equivalent (R5 2600x + cooler for $220)
This leds me believe that BMD borrowed some source-code from Cineform(which is full opensource) to make BRAW.
It's good to see that a GPU can also do a lot of the heavy work and render in real-time, the bad is that the GPU costs $2,500 and the other bad is that the $1.200 RTX2080ti is also fast enough but runs out of memory fast with only 11 GB in an 8k time-line.
The real good comes in Q3 2019 with the 32c/64tr Threadripper at 4.5 GHz all-core for around a $1.000 which can not only speed up R3D workflow, but all workflows.
