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.

The 2990WX has an MSRP of $1799, its successor isn't going to be ~45% cheaper!

@Misha:
I don't think Braw is wavelet-based since there is not the same gain when going half or quarter resolution as with R3D.

I think the successor of the 2990WX will be around the same price $1800...2000 but with 64c/128tr.

The Q3 2019 with the 32c/64tr will be the successor of the 2950x $899, at a $1.000 it's not ~45% cheaper but ~10% more expensive.

I finally built a box that will do real time 4K. i9 9940x cpu and RTX 2080 gpu. No one I know is shooting 8K yet, so I don't know how this box would do.

Red has some demo material.

i9 9940x cpu $1,130 and RTX 2080 gpu $700 ~ $1,830.

or

TR2950x cpu $ 900 and 2x RX VEGA 64 gpu's 2x $400 ~ $1,700.

The cheaper system is atleast 60% faster in resolve.

It will be most likely some Jpeg2000 decoder which Nvidia/RED done, so once this is moved to GPU there is not that much need for fast CPU. It's basically new RED Rocket, just cheaper (not overpriced so called "specialised hardware").
If you pick good format then editing 8K can be fairly easy already.
