never used a Vega card, however my 1080TI Works great :)
Bought a couple of Vega a few months ago, they are great for gaming but seeing that the 1080ti is slightly faster I feel I might have wasted some money and crossfire is terrible in most games. Running on a 4k/60hz monitor on ultra for most games, most games run at ~45-60 fps (Single card). I am planning on using a Samsung CHG90 for gaming which is equivalent to 2 1080 monitors so I expect much higher frame rates. Bigger issues are: -Prices: Bought one at $550 and the other one at $600 but on ebay right now they go for ~$800 which is insane. -Power consumption: I had to replace my 500w PSU. -Heat, they get very hot, I am planning to set a custom loop. -Drivers: sometimes the screen shuts suddenly and I have to hard restart the PC. My overall opinion is that if you can grab it for ~$500 go for it, if not, don't bother with it. I feel like the features that the card include are pretty advanced, but they are not being used correctly and that the drivers are holding this card down. I am an AMD fan, but I am not dumb, and I understand the criticism towards this card. I hope that the next gen NAVI are better and cap compete with Nvidia, but I am starting to doubt about that.
Well, When the amount you paid for AMD's EGG is equal to the amount you would pay for the best video card on the market, then I would argue that you should expect the greatest experience.
Never owned the VEGA. 1080ti is amazing for its price/performance. GTX 1080 is good too. Would'nt roll the dice on these Vega chips now that I know how well Nvidia's work, especially considering Nvidia had the tech manufactured a lot sooner than AMD, who are as usual, Late to the table and carrying less food when they get there.
"Talk about fucking morons" STFU you stupid whining little arrogant child. You came in and whined just as loud as the rest. Stop pointing fingers and acting all high and mighty. You involved your own ignorant-ass and then started name calling. You are just as PETTY and PATHETIC as everyone else in here. Go cry into your pillow, Barbie.
This is the age old conflict. Chevy vs. Ford. Everyone grows up loving one or the other and can find reasons that it dominates. Both these cards are sick. Truly out of reach for most Family having PC elitists.
or don't talk about things you have no understanding of. if your technical knowledge ends at random numbers you see on the screen don't comment on it. the RX vega has a much larger bus width than the 1080 which makes them /almost/ identical in that aspect. if you have 1 lane road with the speed limit of 120 mph vs a 4 lane road with a speed limit of 60 mph you're moving more traffic through the 4 lane road even though it's a slower speed and let me stop you before you try and go and write up an angry rebuttal with "ITS STILL FASTER IN PERFORMANCE" this direct line of comments is about memory not about the overall performance of the gpu.
Last I checked this was a comparison of the 1080ti wasn't it? All these comments are back and forth, using the 1080 in the their examples for price and the 1080ti for performance. Who is ignorant now peeps? Talk about fucking morons. Came in the comments to research and see if I can get some info since I don't tilt to either side and all I see is fanboys crying.
True, but he didn't say 1080ti, he said 1080. There's a big difference between the two, namely the 1080 is 8gb where the 1080ti is 11gb. Meanwhile the vega 64 also has only 8gb of vram. So the VEGA 64 does with 8gb what the 1080ti needs 11gb to do.
Idiot Vulkan is just a successor to OpenGL it has nothing to do with "Windoze" good luck running your "Vulkan" in DOS, IDIOT!
Like they say:"ignorance is bliss."
LOL the Vega is on par with mining compared to the 1080ti... Try again.
Not today it isn't. The Vulcan 64 is the same price or less expensive on the market than the GTX 1080.
They perform just fine, your making it sound as if AMD cards cant run games at all. Sure, Vegas are very expensive and a 1080 would be a better choice for gaming but Vega 64 is still a very fast card.
The Vega 64 is great for gaming. Its not the best, but you will not be disappointed on the performance side of things.
YES!!!
Correct Michael. And on the Vulcan software stack Vega 64 outperforms the Ti version in everything as well. And it is less $$ than the 1080Ti.
Radeon was pretty dumb with marketing there. While I prefer this GPU for professional work even to the Titan Xp (since those 12TFlops mean a lot), I don't really think this was supposed to be marketed as a gaming GPU, but a Proffesional/Gaming GPU.
IF the price comes down on the rx vega 64, I will definitely consider it. I suspect that the miners are going to buy up the market again. I'm very interested to see how it improves as the drivers are tweeked. In the mean time... I'll stick with my gtx.
I doubt the average gamer would hate the rx vega.... They would be happy to have either card!
You are an idiot my friend. For you, don't know the difference between a GTX 1080 & a GTX 1080Ti ...
Vega 64 is half the price my friend. Google before you say something silly.. https://www.pccasegear.com/category/193_1875/graphics-cards/geforce-gtx-1080-ti https://www.pccasegear.com/category/193_1900/graphics-cards/radeon-rx-vega-64
The prices I have looked at show the GTX 1080 ti to be about $100 more expensive. That in itself is not a big deal. What is a huge deal is if you want to go 4k and have Gsync that costs about $900 for the monitor. As opposed to the lower price on the Vega Costco has a 4K free sync monitor for $299. That my friend is a big deal since that $600 monitor difference can be in a second Vega.
When was the last time Nvidia made a CPU lol...
1080ti is for gaylords.
