Adobe Premiere doesn't care about the GPU much, even with pretty heavy effects and 8K you wouldn't notice the difference between a 1060 and a 2080ti, but one thing you usually don't want to do is to pair it with an AMD GPU due Adobe's craptastic support. https://www.pugetsystems.com/labs/articles/Premiere-Pro-CC-2018-NVIDIA-GeForce-vs-AMD-Radeon-Vega-1206/ https://www.pugetsystems.com/labs/articles/Premiere-Pro-CC-2... And 8GB is more than enough, heck if AMD memory management worked as in dev's would've used it then 4GB is enough for 4K even today, there are plenty of GDC talks about it and how some games on average only accessed 3GB of memory for a given level the biggest ones were from Doom and Witcher 3 iirc. This is how the Xbox One X can do 4K even if it's at 30fps with only 12GB of RAM shared between the GPU and CPU and how even the PS4 pro can do 4K with 8GB and in all cases when they can't it's not a memory limitation but rather a fill rate / horsepower issue. I'll take NVIDIA's stellar memory management and compression and tiled rendering over AMD's 1TB of memory bandwidth and 16GB of memory for 4K gaming, and 4K gaming on PCs is well meh, I'm actually regretting getting a 4K monitor and a 1080ti SLI setup something which i will remediate once the 1440P FLAD HDR Gsync monitors come out to the market.

"Heavy" GPU-accelerated 2d effects, like Optical Flow Time Remapping, are used quite often in my experience. Its the easiest way to get the "cool slo-mo" that made movies like 300 popular. Good Youtubers are using the effect a lot in their videos now. You're right about Adobe being bad with OpenCL, but its just an example. But my overall point is that the 2d video editing community is mostly about FP32. A high end FP32 card caters towards 3d renderers, 2d video editors, and others in the professional marketplace. Davinci Resolve users seem to get a bigger benefit out of Vega cards than 10xx series NVidia cards. So it depends on your video editor. ---------- Aside from scientific compute, I'm having issues figuring out where FP64 support is an issue. All of the applications I'm aware of are FP32. There's a clear difference in the rendering of heavy effects (Optical Flow based Resampling) or 3d editors, so a good GPU really makes a difference in those cases. > And 8GB is more than enough, heck if AMD memory management worked as in dev's would've used it then 4GB is enough for 4K even today, there are plenty of GDC talks about it and how some games on average only accessed 3GB of memory for a given level the biggest ones were from Doom and Witcher 3 iirc. XBox and PS4 Pro are bad examples to use. Those systems have far weaker GPUs, and the textures aren't truly 4k. If you enter a game with 4k texture packs (or 8k texture packs, like Star Citizen), you can expect your memory usage to spike significantly. 8GB is still sufficient, but gamers are expecting better and better textures. 4k + 10-bit HDR textures take up a lot of room.

  >XBox and PS4 Pro are bad examples to use. Those systems have far weaker GPUs, and the textures aren't truly 4k. Textures are the same as v.high/high on PC the only thing that some PC games add is an uncompressed texture pack which are simply stupid to begin with. Xbox One X is a great example of a system that can push 4K or near 4K gaming because it does so pretty darn well. The memory capacity is really not an issue with 8GB, in fact the only cases where the 2080 really pulls a head of the 1080ti is in higher resolutions especially 4K. >if you enter a game with 4k texture packs (or 8k texture packs, like Star Citizen), you can expect your memory usage to spike significantly. 8GB is still sufficient, but gamers are expecting better and better textures. Most textures in a game are well beyond 4 or even 8K regardless of the resolution, heck a simple texture atlas is huge. Star Citizen is a crap game to use as an example as both the textures are overall simply horrid and it make PUBG looks like a well optimized title. Overall the 2080 gives you RTX which is RT + Tensor Cores which will become very important as WinML/DirectML games begin to ship since NVIDIA both assisted Microsoft in defining the spec and it's essentially tailored for their Tensor Cores, you get concurrent Int/FP execution per ALU which will give NVIDIA a huge boost as integer shaders (e.g. compute shaders with heavy bool logic) will become more common and you get a more mature ecosystem, better encode/decode and various other small QoL improvements. For gaming specifically the Radeon 7 doesn't have anything to offer other than to those that care more about the brand than what they get for their investment. I really miss the days of the HD4000 series or the days when the R300, and sadly I don't see AMD getting out of this cycle any time soon, Fiji was late and underwhelming, Vega was late and underwhelming, and now Radeon 7 is late and underwhelming. If Navi is another mid range GPU will see 15%-20% improevemnt over Polaris if we're lucky, once we get closer to Feb 7th I'm pretty sure we'll see that in 1080p there is likely no difference between VEGA64 and Radeon 7 and the only place we see the difference is in 4K due to slightly higher fill rate and more bandwidth since AMD still can't get delta compression to work correctly.

It's "enough" because it has to be. Game developers need to constantly pay attention to these budgets because people who play their games have hardware with limited performance. If everyone had more of a resource then none of them would say no to that particularly now that GPU compute is becoming more popular in games.

  If the Witcher 3 team found they actually accessed just over 3GB of memory within a given stream window then yes while its true that it’s all about managing resources this isn’t an issue that requires compromise just yet. Doom had a similar talk, resource management is a key factor in game development. GPU compute is a completely different issue.
