GTX 1080 good for 4K?

For those of you that have a GTX 1080. Is it sufficient to run 4K resolution at 60FPS?

My TV seems to have limited resolutions available so I really need a card that can drive the TV at 60FPS. The 1070 I have at the moment can just about mange it with the reduced detail field (green field).

My CPU is a 6700K with 16Gb.

Thanks

I would go for the 1080 ti. It's 35%faster than the 1080. It should do 4k with no problem. I'm in the process of getting one with a aftermarket cooler. Myself.

Or wait a couple of months until the full effect of AMD's new chips drive the prices down on all the NVIDIA chips.

I agree, I would wait a little bit. The new AMD GPU's sound fantastic based on rumor control, for example a 1080Ti killer with 20% better performance and selling for $350-$400 bucks...

I'm not holding my breath on that one, zero hype and I heard it's going to have 8gb of VRam so it's probably going to be a solid mainstream card but not sure about being able to compete with the high end stuff. 1080ti has 11gb of useable VRam which is important in the higher resolutions.

Ryzen is nice but not really adequate for gaming. The kabby Lake 7700k does it better. The amd chips are better for content creation.

Mid and High End cards will get the HBM2 memory...

AMD will begin the "Vega" architecture lineup with the Vega 10, an upper-performance segment part designed to disrupt NVIDIA's high-end lineup, with a performance positioning somewhere between the GP104 and GP102. This chip is expected to be endowed with 4,096 stream processors, with up to 24 TFLOP/s 16-bit (half-precision) floating point performance. It will feature 8-16 GB of HBM2 memory with up to 512 GB/s memory bandwidth. AMD is looking at typical board power (TBP) ratings around 225W.

Next up, is "Vega 20." This is one part we've never heard of today, and it's likely scheduled for much later. "Vega 20" is a die-shrink of Vega 10 to the 7 nm GF9 process being developed by Global Foundries. It will feature 4,096 stream processors, too, but likely at higher clocks, up to 32 GB of HBM2 memory running full-cylinders at 1 TB/s, PCI-Express gen 4.0 bus support, and a typical board power of 150W.

Apparently AMD will be releasing their "Flag ship" CPU soon, a 12-Core and 16-Core (32 Thread) clocking at 5ish GHz...

But for right this minute, the I7-7700k and 1080Ti would be the best combo for strickly gaming. If rendering videos or other number crunching work, the Ryzen would be a better choice. Either way you can't go wrong...

For my money... I am staying with WinTel and waiting for the prices to drop. If Ryzen had been out for a year or so, maybe then. I am not going to be the experiment, but I will enjoy the price drop.

I agree, you can be caught up in wait until next year and never make a decision. What I am saying is AMD just dropped many new chips on the market RECENTLY. Those chips are going to have an effect in the next 3 to 6 months as the market adjusts to 50% off chips doing the same thing. If these chips prove out, you are going to save some coin. On the other hand, if you need it now, you need it now... good luck.

Well I can now answer my own question.....

The answer is NO, a GTX 1080 cannot run 4K at 60fps and neither can my new MSI 1080 TI Aero!
(with I7 6700k and 16Gb)

I have had to drop the resolution to 1440p and now it is happy.

My GTX 1070 is now paired with an AMD 1700x running on my other machine, it is quite happy running 1080p at 60fps.

I run 4k at over 120fps on a 1080ti with a 6700k. 16gb ram. The settings are turned up but I disabled the motion blur. I've seen were a few people with high end systems seem to have a problem but other people don't. On the grasslands field the frames go over 400fps. There is a guy here with a single Titan Pascal which is just a little faster getting the same performance as me.

I have the MSI 1080ti Gaming X.

So you are getting more than twice the performance of my machine.

I will run the superposition benchmark and compare it with your results.

I was getting 30-40fps with my twin 970's at that resolution. That is equivalent to the 980ti. That wasn't acceptable to me hence the upgrade to the 1080ti. The engine that RF-X uses, like the superposition benchmark isn't really reliant on a fast CPU. It's all about the GPU.


Make sure you are up to date with the RealFlight updates too, they made some changes to how the software works and it really helps performance. I turned off depth of field, bloom, and blur. I don't like those effects and have never used them in any simulator.
