NVIDIA is the performance king of graphics cards, period.
You might notice that AMD Radeon graphics cards are completely absent from this testing... and that's because I couldn't even get the Dell UP3218K monitor detecting on a Radeon GPU. I tried:
- AMD Radeon R9 Fury X
- AMD Radeon R9 Nano
- Radeon RX 480
- Radeon RX 570
- Radeon RX 580
- AMD Radeon RX Vega 56
- AMD Radeon RX Vega 64
- AMD Radeon RX Vega 64 LCE
None of these cards would work with the Dell UP3218K on the latest (or the last few driver sets) but they would detect the 8K monitor and it would work with the default drivers that come with Windows 10. Alternatively, if I powered the machine off (and didn't uninstall the Radeon drivers), took the Radeon card out, installed any GeForce card and turned it on, the 8K monitor would detect.
Weird AF. I reached out to AMD to let them know what's going on, but the Radeon team is so low on staff since they've all left... I don't have many people to go to right now, with technical marketing kind of dead. I'll update this article with a '2.0' piece when/if 8K is repaired on AMD. Until then, sorry Team Red... 7680x4320 is just too hardcore for Radeon right now.
Spending $2400 on the two GeForce RTX 2080 Ti graphics cards and another $3700 on the Dell UP3218K is pretty damn crazy as you're looking at a minimum of $10,000 on the PC at that point. Not many people are going to do that, and if they do they can now take a look at real-world 7680x4320 results to see if they want to buy an 8K display.
The other purpose of doing this is because I love to live on the edge. 8K isn't normal, it's beyond the realms of normal. 8K gaming might not even become a reality, but the entire point of buying this display was so I could push every graphics card to its limit. NVIDIA's new Turing GPU architecture, the crazy amounts of horsepower and GDDR6 bandwidth at its disposal, really gets to stretch its legs at 8K.
We can really see the difference between the older Pascal architecture and the new Turing architecture at 8K, with all of that additional bandwidth and horsepower being utilized much more at 8K versus 1080p and 1440p. 4K is still a point of domination for Turing as well, but these results blew even my mind. I didn't expect to get close to 8K 60FPS gaming in 2018, and yet... here we are.
